“Skin Regimen Polypeptide Rich Cream”
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:
carnosine, 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: butyrospermum parkii butter, glycine soja oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl tetrapeptide-2, palmitoyl tripeptide-5
“Ideal for those with wrinkles, signs of ageing, stress and fatigue.”
This product contains acetyl tetrapeptide-2, carnosine, palmitoyl tripeptide-5. These ingredients might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.
This product contains antioxidants (carnosine) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

"Comfort Zone - Skin Regimen Polypeptide Rich Cream" has a good moisturizing formula. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (carnosine, glycerin and caprylyl glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (glycine soja oil, oleyl erucate, orbignya oleifera seed oil, butyrospermum parkii butter and c10-18 triglycerides) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
