You only need to improve inner elasticity.
Why have we used so many functional cosmetics all this time?
We all know the answer. It's because that's how cosmetic companies make money easily.
For over five years, Mediviti has had supporters evaluate new products on Wadiz,and has blended ingredients that can fill all basic products with elasticity, into their formulations.
Functional ingredients can fast-forward the time it takes to see effects,but we know that the foundation of good skin must be inner elasticity.



In fact, our skin
is perfectly vertical to gravity.
So, skin illustrations shouldn't be shown lying horizontally with gravity,but should be displayed standing vertically. As soon as we set it vertically,
- it became clear why a toner with impressive pore clinical results brought no change to me,
- and why even diligent use of whitening ampoules made it hard to see visible changes,
because we failed to properly address the one key factor: elasticity.It was as if we could immediately identify this deceptively simple cause.



As of February 21, 2024,
- Rather than having a 4.9 rating from 10 reviews,Over 999 reviews A 4.5 rating is more meaningful
- BeautyOnly As a brand dedicated to researchConsistently Releasing new productsConsistently It is more important whether we have consistently received reviews
We believe that our supporters share the same thoughts as Medibeauty.











The retinoid serum is exclusively distributed on Wadiz.

This is Medibeauty's unique cream-water.




To reach the deepest layers of the skin
It must be small enough to penetrate the skin.
That is 500 Daltons. If the ingredient is larger than this... It may be shocking, but it is meaningless.
So, just as we carefully examine each ingredientWe also need to check whether these ingredients have undergone a low molecular weight process under 500 Daltons We must consider this as well. If it has not undergone a low molecular weight process, no matter how hard you try, it cannot penetrate the skin's surface.

If it is not low molecular weight,
There is no point in pressing and absorbing it...!


Just like collagen, after your 20s and 30s,
The more the ingredient almost disappears,
Don't just check whether the ingredient is present or not before buying.
Because even if collagen just brushes by, it can be called a collagen ampoule.
Whether it is low molecular weight, or
Make sure to check before purchasing.
In Korea, there is still a tendency to focus on how much of a certain ingredient is used,
- But as time goes by and customers' knowledge of cosmetics deepens,
- 'So, did you make that ingredient under 500 Daltons or not?' I believe the day will come when people naturally check even that.
Just like how we now casually read the full ingredient list printed on the box as soon as we buy cosmetics and say, 'Oh, purified water is listed first?'

The first ingredient in the Nunbadi Wrinkle Serum is
Ultra-low molecular collagen under 300 Daltons, It is.




By generously blending it,
We achieved an ultra-high concentration formula that hardly feels like a serum.
Its efficacy is almost beyond that of regular cosmetics.
The stimulation is way too strong.
For retinol to form collagen in the skin, it must be converted into 'retinoic acid' that the skin can accept. Retinol changes to retinyl palmitate, and then retinyl palmitate is sequentially converted to retinal.
And then, it must properly settle on the 'retinoic acid receptor(This is the starting point that accepts retinoic acid and converts it into collagen. It's like a transfer platform.)' that everyone has in their skin.



First-generation retinol is
simply applying the most basic form of retinol to the skin. Among the various generations of retinol, it is the most affordable so it is still used.
- However, what the skin really needs is 'retinoic acid,' which is retinol that has undergone several transformations. Since the process of converting retinol to retinoic acid is long, a lot of irritation occurs.
- That is why you can often find reviews of retinol cosmetics on the market saying the irritation is too severe or that their skin was actually damaged.
If you remember trying retinol and thinking it didn't suit you, it's highly likely you only used this first-generation retinol.

Second-generation retinyl palmitate is
a form where retinol is first converted to retinyl palmitate and then applied to the skin. It was much better than retinol, but failed to reduce the molecular size,(Remember the 500 Dalton rule?) It disappeared without a trace.

Third-generation retinal was
successful in reducing the molecular size, but caused severe irritation when applied to the skin.The rate of collagen formation was much faster than the first or second generation, but since the irritation issue was not resolved, it is now a rarely seen ingredient.

No need to transfer
It's like taking a direct route.
To form collagen, it had to bind to the retinoic acid receptor, and because of this binding, the constant transformation caused skin irritation. It's like getting exhausted trying to transfer trains in a subway packed with people.
Retinoids, without receptor binding,simply start forming collagen as soon as they touch the surface of the skin, without transferring, reaching the destination directly. There is no need for unnecessary irritation, and it diligently produces collagen for up to 15 hours.

Completed non-irritation clinical trials.
Regardless of age or skin type,
Let's focus on producing collagen together.


It took 63 years to go from the first to the fourth generation.
Was it an ingredient worth waiting for?
Even if you ask a hundred times, the answer will always be 'yes.' While 67% low-molecular collagen alone can replenish lacking skin elasticity, So that the inner elasticity does not fade away, the collagen production factory must keep running continuously.
A collagen factory that operates without rest, and this is done without any irritation,(= Without burdening the skin) is made possible by retinoids.


If you apply it in the morning, retinoids enable collagen formation for up to 15 hours, and if you apply it in the evening, another 15 hours are possible. As you age, you can quickly replenish the collagen that naturally decreases.
In fact, fourth-generation active retinoids showup to 8 times faster anti-aging effects compared to first-generation ingredients.



Anti-aging that is 8 times faster is possible without irritation with1% of fourth-generation retinoids. You might think, 'Huh? Only 1%?' but if you convert this to ppm,it's 10,000 ppm. Suddenly, it seems like a lot, right? Since ppm is a unit for indicating low concentrations, Medivity doesn't like to play games with ppm.
However,in the market, just because a product contains 0.1% first-generation retinol, prices often exceed 70,000 won,which is a sad fact that such prices are set without hesitation.

Medivity always welcomes comparisons.



Thanks to the extremely fast improvement speed,we do not limit ourselves only to clinical trial results.Visibly Wrinkles are smoothed out. Eye Body Wrinkle Serum There's a reason why this name didn't come out of nowhere.
You don't have to wait long to see these effects. Some people who paid for and used it found three days was enough.



Matrixyl-Synthe'6 also came all the way from France.
If you know the authority France holds in the cosmetics ingredient industry,
You might see Paris not as a city of romance, but as a city of science...!


With just Matrixyl-Synthe'6,
Your skin barrier may not be lacking,
Matrixyl-Synthe'6 is an ingredient based on peptides.Peptides, simply put, are compounds of proteins, Since the skin is made up of proteins, peptides not only directly affect the skin barrier but also play a role in activating new skin.
In other words,Just as you can't build a building without enough bricks, If you lack peptides, you can't create new skin.

No matter how much basic skincare you apply,
If it doesn't containPeptides, it's meaningless. I do.
Although Matriksyil-Syn 6, which is recognized for its efficacy in 33 countries, is already sufficient,Just as you need more bricks to build a bigger building, the more peptides reach deep into the skin and are sufficiently supplied,Visible skin improvement is possible.


Absorption rate when peptides are not low-molecularized
If this happens, peptides become meaningless even if they are present.

In the Mediviti Eye Body Wrinkle Serum,
Absorption rate of 11 types of fully low-molecularized peptides
I repeat,
The 500 Dalton rule is the key.
What Mediviti started,Low-molecular technology for all active ingredients Someday, this will become the standard for all Korean cosmetics!




- You have probably heard a lot about EGF.Activation of the skin helps improve the skin barrier. Especially,When combined with peptides, the synergy is explosive Peptides are the bricks needed to build new skin, and EGF can freely use them to fulfill its role.
- FGF is used as a pair with EGF,To ensure that EGF reaches the deepest layers of the skin, it acts as a pathway. When purchasing EGF cosmetics, make sure to ask if FGF is also included.


- Bakuchiol is actually an incredibly popular ingredient in overseas beauty markets, even more so than in Korea.As a plant-based vegan retinol ingredient, it helps with elasticity as well asimproving radiance. It provides these benefits.
- It's not the first-generation retinol, which was highly irritating and just sat on the surface of the skin,but an upgraded version in line with advances in technology and science—vegan retinol—so it pairs very well with fourth-generation active retinoids. That's why it's such a compatible ingredient.
- Bakuchiol alone is now being used as the main ingredient in new cosmetics,and it's considered a premium ingredient, worthy of being the main component in most products. In Mediviti's Eye-Body Wrinkle Serum, the fourth-generation active retinoid is so powerful that bakuchiol is used as a sub-ingredient, but it is by no means a cheap ingredient.(In fact, it's very expensive... ^_ㅠ)


- Alpha-bisabolol is a whitening functional ingredient officially registered with the Ministry of Food and Drug Safety. Usually, when it comes to whitening, most people think of niacinamide,Mediviti does not usually choose common ingredients—in other words, ingredients that are inexpensive and accessible to everyone—unless there is a special reason.
- For example, niacinamide needs to be blended at 2–5% to function as a whitening ingredient,while alpha-bisabolol only needs to be blended at 0.5%. You can do it. Please remember that ingredients unfamiliar to us are usually those with higher production costs.


- Adenosine is an ingredient officially registered with the Ministry of Food and Drug Safety for its wrinkle improvement function. Even with just 0.4% blended, it is effective enough as a functional ingredient for wrinkle improvement.
- In fact, when elasticity is restored, wrinkles naturally follow, so adenosine is blended only at the maximum ratio allowed by the government.



On the surface of the skin
There are no active ingredients that simply disappear without being absorbed.
Not only collagen with an ultra-low molecular weight under 300 Daltons,Mediviti blends all active ingredients in low molecular form. This is why the Eye Body Wrinkle Serum can visibly accelerate skin improvement.

In fact, people who make cosmetics often joke, 'Why make something that doesn't even get absorbed?' but they can't even imagine blending all active ingredients in low molecular form.
- They have to check one by one whether each ingredient is stably low-molecularized,
- and also whether these low molecular ingredients mix well with others to create synergy.
So when Mediviti says, 'We have made all active ingredients low molecular,' industry professionals are genuinely envious.It's like we've accomplished an expensive and complex process that others want to try but can't even attempt.A kind of vicarious satisfaction Indeed.

That's why Mediviti
is called the cosmetic that industry professionals buy and use.
Researchers know the ecosystem of ingredients so well, they understand how costly and troublesome it is to make products like this.It's just like how buying a cake is much more efficient and affordable than baking one yourself. You just buy and use the Mediviti product.


Makes you wonder if this is really a serum.
Highly concentrated cream-water formula.
It looks like a cream, but when applied, it melts and absorbs like a water serum. In fact, water-based formulas that flow like water are easy to use, so anyone can easily purchase them.(Because we want to make a lot of money) We wanted to make a water-based formula.
But with 67% low-molecular collagen, 1% fourth-generation active retinoid, 11 types of peptides, and 3% French-patented Matrixyl-Synthe'6, we just couldn't achieve a water formula. You could add purified water, butI absolutely hated the idea of adding purified water, which has no real function, just for the sake of 'texture.'

So we kept this formula that just 'looks' thick.
We preserved it as is.
It only looks thick on the outside,but when applied, it's just like water. It is.
You'll think, 'So this is why it's called a serum!' That's why we named it a cream-water formula.

Because we were so stubborn about this,
the manufacturer kept threatening to cut us off every time.

It looks thick,
but unlike creams that stay thick until applied, it's different.

Thanks to its low molecular weight, it melts smoothly the moment you apply it.
It is a unique formula that absorbs like water.
It absorbs very quickly and leaves no stickiness.Because it feels fresh, You can pump and apply generously multiple times. The active ingredients are low-molecular, so they are absorbed as soon as you apply them, and even if you use a lot, your skin won't reject it.
Personally, I recommend applying one pump lightly in the morning,and before going to bed, use three to four pumps generously,from your face down to your neck, when applying. I recommend this. Because it absorbs quickly, it won't rub off on your pillow.









Is this price reasonable?
If you're curious,feel free to search for it.
Mediviti welcomes comparisons.




Now that we've shown you the price,
Can we talk a bit more...?
Starting with 67% low-molecular collagen from France, fourth-generation active retinoids, plus EGF and bakuchiol...It's as if Mediviti is obsessed with elasticity,(I can't really say that's not true.)
- The reason we developed an eye-and-face wrinkle serum focused on deep elasticity is,
- because if you improve deep elasticity alone, many peopleWorrying about each issue separately,
Solve wrinkles, pores, skin texture, whitening, and radiance all at once. Because you can do it all at once.
Since we've shown you even the price you were most curious about, we can finally take a breath,Let me explain the reasons one by one.



When a fully inflated balloon starts to lose air, it becomes wrinkled. This is because the surface, which had stretched to fit the volume, cannot adjust to the shrinking volume, causing the surface area to increase.
As the elasticity inside the skin decreases,When the surface area of the outer skin becomes relatively larger, wrinkles form.

When the surface area of the outer skin increases, the pores exposed on the surface also enlarge.
We usually think that 'tightening the outer skin' reduces pores, but that's no different from temporarily compressing a wrinkled balloon.Just as everything is resolved when you refill a balloon with air, filling the skin's inner elasticity is the easiest way to tighten pores.

It's only natural that stretched outer skin and enlarged pores create rough skin texture. Dead skin cells can also contribute to roughness, but their effect is like dust sticking to a balloon—minimal.
When the inner skin's elasticity is restored,the wrinkles and pores where dead skin cells may have accumulated are smoothed out, so ultimately, the easiest way to refine skin texture is by restoring inner skin elasticity.

In fact, many people's skin is already white and bright.However, as inner elasticity is lost and the skin stretches,shadows form in the gaps of the outer skin, There are surprisingly many people whose skin appears 'dark.'
Think about the people around you. Unless they intentionally tan, people with firm skin rarely have dark and dull skin.

When inner elasticity is lost, the skin texture becomes rough due to wrinkles and enlarged pores, causing light to scatter. Just as a calm and steady water surface reflects beautiful scenery and reveals the depths below,When you restore inner elasticity and refine the skin texture, naturally transparent skin is achieved.

With and without light scattering,
You understand right away, don't you?
Remember, whitening that erases shadows andradiance that transparently reflects light are different concepts.





Mediviti
has returned with a completely new story.
Supporters who have followed Mediviti may know. The original story of the wrinkle serum was not like this. There was more blue, and we used a lot more GIFs.

It felt a bit like this, haha.
But this time, we sharpened our focus and calmly concentrated on explaining the ingredients and components as simply as possible.The name of the product, Eye-Body Wrinkle Serum, naturally emerged as part of the explanation process.
Hmm... Actually, this story
is closest to our true selves.
Manufacturers and Wadiz managers who have meetings with us are always surprised.In the story, we seem very bright, cheerful, and as if we have an MBTI E personality,In fact, everyone who runs Medivity is calm, gentle, and quiet.

If a meeting goes wrong even once,
It becomes an endless cycle of awkward silence...
So then, why did we write our story
in such a lively and popping way?
We thought that was the only way
you would listen to our story.
It's really unfortunate that it has now become just another advertising phrase, but the cosmetics market is so competitive that marketing costs are almost everything. Since these are products used daily, once you win over a customer, you can achieve stable sales. That's why there are so many provocative ads.
So Medivity, in that market,
wanted to meet even just one person somehow,
so we pretended to be bright and lively,as if we were like that. But actually,
- we use plant-derived ingredients with all EWG Green Grade components,
- and find combinations that deliver effective results,
- to create cosmetics not for anyone else,but for Koreans, that truly suit them, and that's what we make.
We put our sincerity into making these products, so if we remain unknown just because we're a small brand, it would feel so, so unfair.We wondered how we could reach our customers, and before we knew it, we felt like we had become just like everyone else.

Because no matter what we look like,
If the products we introduce reach our customers with visible results,
We believe our customers will come back to us even without flashy detail pages or dazzling designs.

When a project succeeds,
Medivity has run many projects on Wadiz, but honestly, our product lineup itself is not flashy.
- It takes years to launch a single product,
- So after hitting it big with one project, it's impossible for us to quickly create a trendy, popular product concept these days,
and showcase it. It just takes too much time... haha.
Every time we succeed in a project, we consistently invest in developing and upgrading new products. It just takes a long time, so it may not be obvious.But this is the unique pace of Medivity, where we pour our sincerity into every step.
Even if you just laugh it off, we will continue to invest all project proceeds into new product development and upgrading existing products, just as we always have at our own pace.

Some of you may already know,
The Sootkama Cleanser, which raised 100 million won on Wadiz, took two years to upgrade,
and all of those costs came from the success funds of Wadiz projects.



Q. Is it safe for sensitive skin?
A. The Eye Body Wrinkle Serum contains active retinoid ingredients, so unlike traditional vitamin A ingredients such as retinol, retinyl palmitate, and retinal, it does not require conversion to retinoic acid for skin absorption, allowing it to be absorbed directly without irritation.However, as always when using a new cosmetic, we recommend that those with extremely sensitive skin do a patch test behind the ear before applying it to the face. Also, it is best to apply it as the last step of your basic skincare routine.
Q. Can pregnant women use it?
A. If you are pregnant or breastfeeding, we recommend that you do not use it.
Q. Can I use it during the day?
A. The Nunbadi Wrinkle Serum may increase your skin's sensitivity to sunlight, so please make sure to use sunscreen. Even if you only use it at night, the retinoid ingredient synthesizes collagen in the skin for 15 hours, so we strongly recommend using sunscreen when going outside.
Also, please avoid using products containing chemical peeling ingredients (AHA, BHA), physical scrubs, or combining with beauty devices or procedures that may irritate the skin.
Q. Can teenagers use it?
A. You may see even better results if you use it during adolescence when sebum secretion is active.The pore improvement effect of the retinol line's ingredients is so outstanding that it is documented in SCI papers. You may see even better results if you use it during adolescence.
Notice.
All before and after photos used in the story were taken after 2 weeks of use and have not been retouched in any way.
However, as with all cosmetics, individual results may vary.
