Works for
Anti-agingMadecassoside, Acetyl dipeptide-1 cetyl ester + 1 moreMay help
“Anti-Wrinkle Firming CareA daily care product to help reduce the appearance of deep wrinkles and restore firmness.”
This product contains acetyl dipeptide-1 cetyl ester, madecassoside. 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.
Anti-oxidationSide benefit · Madecassoside, Ascorbic acidWorks well
This product contains antioxidants (madecassoside) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
MoisturizingSide benefit · Madecassoside, Acetyl dipeptide-1 cetyl ester + 8 moreWorks well
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, hydrolyzed hyaluronic acid.
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: caprylic/capric triglyceride, dimethicone.
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, madecassoside

Product summary
"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.
