WIMJ summary for anti-aging

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl dipeptide-1 cetyl ester, 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.

WIMJ summary for evens skin tone

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.

WIMJ summary for exfoliation

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.

From product name

WIMJ summary for moisturizing

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: 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 dipeptide-1 cetyl ester, ceramide np, hydroxypalmitoyl sphinganine

Ingredient	Effectiveness	Concentration	Irritancy
2-oleamido-1,3-octadecanediol	HIGH
squalane	HIGH
oryza sativa bran oil	HIGH
