Effective ingredients missing or their concentration is too low

Retinyl palmitateUnder-dosedThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.05–0.25%

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

What the product description says
“Purifying Mask nourishes rough, dull, dehydrated and stressed skin, while reducing sebum production and killing bacteria to help clear breakouts.”

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: sodium pca.

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: glycine soja oil, vitis vinifera seed oil.

Glycine soja oilKey active· EmollientEffect: HighA good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.~1.4–2.1%
Vitis vinifera seed oilKey active· EmollientEffect: HighA great emollient that can also have anti-oxidant properties~1.2–1.9%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.8–1.2%
