What the product description says
“Reveal Skin Youthful”
Source: Yesstyle

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: retinyl acetate.

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.

What the product description says
“Even Skin Tone”
Source: Yesstyle

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: yeast extract.

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.

What the product description says
“With additional moisturising effect, it penetrates nutritions into deeper layer of skin hence to protect skin texture from being damaged and retain freshness of your skin.”
Source: Yesstyle

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": hyaluronic acid, yeast extract.

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).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

This product contains antioxidants (ascorbic acid, ubiquinone) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - yeast extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Product summary

"CS12 - Active Night Serum" could be helpful for: Anti-aging and Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid) 3.90% - 5.90% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
  • Humectants (hyaluronic acid 0.45% - 1.00% and yeast extract 4.90% - 7.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
