Anti-agingNiacinamide, Acetyl tetrapeptide-9 + 6 moreStrong evidence
“A clinically backed face cream that provides long-lasting hydration and helps reduce the appearance of fine lines for a smooth, supple feel.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, acetyl tetrapeptide-9, copper tripeptide-1, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
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.
MoisturizingAcetyl tetrapeptide-9, Niacinamide + 23 moreStrong evidence
“A clinically backed face cream that provides long-lasting hydration and helps reduce the appearance of fine lines for a smooth, supple feel.”
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:
anhydroxylitol, glycerin.
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: helianthus annuus seed oil, myristyl myristate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, acetyl tetrapeptide-9, copper tripeptide-1, niacinamide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1
Anti-blemishNot advertised by the brand · Niacinamide, Aloe barbadensis leaf juiceStrong evidence
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.
Evens skin toneNot advertised by the brand · NiacinamideStrong evidence
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: hydroxyethyl urea, niacinamide
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.
ExfoliationNot advertised by the brand · Hydroxyethyl ureaStrong evidence
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.

A naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.
