WIMJ summary

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, vitis vinifera seed extract.

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.

Ingredient	Effectiveness	Concentration	Irritancy
acetyl glucosamine	HIGH
acetyl hexapeptide-8	MEDIUM

What does the product description say?

"A brightening two-step mask that delivers brightening benefits by diminishing the look of dark spots and discoloration for a vibrant, luminous glow."

WIMJ summary

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

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: morus nigra root 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 does the product description say?

"Step one is a soothing primer that infuses skin with soothing moisture, preparing skin for step two, the brightening power of the gel cream."

WIMJ summary

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: algae extract, faex.

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: squalane, algae extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl glucosamine, acetyl hexapeptide-8, linoleic acid, tetraacetylphytosphingosine

Ingredient	Effectiveness	Concentration	Irritancy
camelina sativa seed oil	HIGH
acetyl glucosamine	HIGH
acetyl hexapeptide-8	HIGH
