Product summary

Ingredient callouts
- A good concentration of Niacinamide (1.40% - 2.10%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.75%) it cannot have a noticeable benefit for the skin.
- This product contains an effective form of Retinoids (vitamin A): retinol 0.15% - 0.55% and retinol 3.00% - 4.50%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
- Ceramides (ceramide np 0.30% - 0.70%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
- Peptides (sh-polypeptide-22 0.10% - 0.35% and sh-oligopeptide-1 0.10% - 0.50%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
- Another helpful ingredient in this product is Linoleic Acid. It is one of the fatty acids naturally present in skin. It is part of the skin barrier. Preliminary research shows that it might be able to reduce clogged pores.
- Humectants (fructose 0.40% - 0.95%, fructooligosaccharides 0.40% - 0.95% and glycerin 1.80% - 2.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Benefits
Promise: Anti-blemish
What does the product description say?
Minimizes the look of pores and improves uneven tone and texture.
This product can help reduce breakouts and clogged pores because it contains the following ingredient: retinol. This ingredient is used for treating acne and can have a noticeable effect.
In addition, this product contains niacinamide. It can help in reducing blemishes, even though it is less effective.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| niacinamide | HIGH |  |  |
| retinol | HIGH | | |
| linoleic acid | MEDIUM |  | |
Promise: Anti-aging
What does the product description say?
The key ingredient in this mask is yuzu, a citrus fruit known to promote anti-aging and rejuvenation with powerful antioxidants and vitamins.
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid, retinol, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: sh-oligopeptide-1, sh-polypeptide-22.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| ascorbic acid | HIGH | | |
| niacinamide | HIGH | | |
| retinol | HIGH | | |
Promise: Evens skin tone
What does the product description say?
The Yuzu Vitamin C Sleep Mask also includes a K-beauty favorite, niacinamide, to brighten and retinol (Vitamin A) to minimize appearance of pores, even out tone, and smooth skin texture.
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid, retinol.
In addition, this product contains niacinamide. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| ascorbic acid | HIGH | | |
| niacinamide | HIGH | | |
| retinol | HIGH | | |
Promise: Moisturizing
What does the product description say?
Use this as a part of your PM routine, applying on top of your moisturizer and left on overnight.
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
fructooligosaccharides, fructose.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, phenyl trimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, niacinamide, sh-oligopeptide-1, sh-polypeptide-22
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| caprylic/capric triglyceride | HIGH | | |
| phenyl trimethicone | HIGH | | |
| polymethylsilsesquioxane | HIGH | | |
Other benefit: Exfoliation
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: retinol.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| retinol | HIGH | | |
Other benefit: Anti-oxidation
This product contains antioxidants (ascorbic acid, retinol, tocopherol) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| retinol | HIGH | | |
| tocopherol | HIGH | | |
| ascorbic acid | HIGH | | |
