Product claims breakdown

Anti-aging

RETINOL at ~0.1–0.35%

Strong evidence

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

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.

RETINOLRole: HeroTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating~0.1–0.35%

GlycerinRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.5–5.3%

DimethiconeRole: Key activeA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2.8–4.2%

Cetearyl alcoholRole: Key activeA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~1.4–2.2%

Dimethicone crosspolymerRole: Key activeUsed to create a thicker product texture. Helps soften the upper layer of the skin and might be able to prevent moisture loss from its surface~0.4–1%

CyclopentasiloxaneRole: Key activeA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~0.4–0.95%

Sodium polyacrylateRole: Key activeUsed to create a gel-like product texture, as well as to stabilize emulsions~0.35–0.85%

Sodium hyaluronateRole: Key activeOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.05–0.25%

Moisturizing

4 ingredients contribute at the levels below

Good evidence

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: glycerin, sodium hyaluronate.

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: dimethicone, cetearyl alcohol.

CYCLOPENTASILOXANERole: Key activeA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~0.4–0.95%

DIMETHICONERole: Key activeA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2.8–4.2%

GLYCERINRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.5–5.3%

Exfoliation

RETINOL at ~0.1–0.35% delivers this without it being on the label

Quiet bonus

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.

Evens skin tone

RETINOL at ~0.1–0.35% delivers this without it being on the label

Quiet bonus

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

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.
