Moisturizing

Niacinamide, Sodium hyaluronate + 16 more

Works well

What the product description says

“An intensive whitening serum which supplies nutrients and moistures to skin for a radiant-looking complexion.”

Source: Yesstyle

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: arginine, betaine.

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: arginine, hydrolyzed collagen.

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

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.7–2%

Hydrolyzed collagenKey active· Humectant, EmollientEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~0.4–0.65%

Diisostearyl malateKey active· EmollientEffect: MediumHelps to soften the upper layer of the skin~0.35–0.6%

Glyceryl acrylate/acrylic acid copolymerKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and provide a longer-lasting hydration. Can create a thicker product consistency~0.3–0.6%

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~0.3–0.6%

ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.25–0.5%

Limnanthes alba seed oilKey active· EmollientEffect: HighThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~0.15–0.3%

Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~0.15–0.3%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~4.8–5.9%

Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~0.3–0.55%

Anti-aging

Side benefit · Niacinamide, Limnanthes alba seed oil

Works well

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

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.

Limnanthes alba seed oilEffect: LowThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~0.15–0.3%
