Works for
Evens skin toneAscorbic acidWorks well
“Formulated with 23% Vitamin C plus Vitamin E to fade hyperpigmentation, even skin tone and combat signs of aging.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.
In addition, this product contains hydroxyethyl urea. 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.
Anti-agingAscorbic acid, Adenosine + 1 moreWorks well
“Formulated with 23% Vitamin C plus Vitamin E to fade hyperpigmentation, even skin tone and combat signs of aging.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid, adenosine.
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.
MoisturizingBetaine, Polyglycerin-3 + 5 moreWorks
“Also contains panthenol to soothe and fortify skin, while birch juice keeps hydration levels high.”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": betaine, hydroxyethyl urea.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
Anti-oxidationSide benefit · Ascorbic acid, Adenosine + 1 moreWorks well
This product contains antioxidants (ascorbic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
ExfoliationSide benefit · Hydroxyethyl ureaWorks well
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: hydroxyethyl urea.

Product summary

Ingredient callouts
- 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 (23.00% (declared)) it cannot have a noticeable benefit for the skin.
- Adenosine 0.20% - 0.80%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
- Humectants (hydroxyethyl urea 0.45% - 1.05%, polyglycerin-3 1.40% - 2.00% and betaine 2.80% - 4.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
