La Roche-Posay Redermic [C] Dry Skin

"La Roche-Posay - Redermic [C] Dry Skin" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. La Roche-Posay - Redermic [C] Dry Skin ticks this box. Glycerin, hydrolyzed hyaluronic acid, butylene glycol and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (isocetyl stearate, caprylic/capric triglyceride, dimethicone and caprylyl glycol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

• This product also contains vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this moisturizer it is used for stabilizing other ingredients in the formulation. In this concentration (2.00% - 2.50%) it cannot have a noticeable benefit for the skin.
• We like that this moisturizer contains peptides (acetyl dipeptide-1 cetyl ester 0.20% - 0.40%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
• This formulation also includes actives derived from an extract of the Centella Asiatica plant (its other name is Gotu Kola): madecassoside 0.50% - 0.75% The Centella Asiatica actives help strengthen and restore the skin barrier, decrease inflammation in skin and neutralize free radicals. They also can help to reduce scarring. The good news is that these actives work even in low concentrations.
