La Roche-Posay Redermic Retinol Intensive Anti-Aging Treatment Cream

"La Roche-Posay - Redermic Retinol Intensive Anti-Aging Treatment Cream" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin, sodium hyaluronate 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 (glycine soja oil, cetearyl alcohol, caprylyl glycol, isohexadecane and isostearyl neopentanoate) 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 moisturizer contains an effective form of retinoids (vitamin A): retinol 0.20% - 0.75%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of retinoids is that they can be irritating. If you are not already using a retinoid in your routine, it is best to start slowly and apply the retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily. Because of the irritation risk of retinoids, we recommend to have another, retinoid-free moisturizer in your routine to use on the alternative days or when your skin feels dry.
• We like that this moisturizer contains peptides (acetyl dipeptide-1 cetyl ester 0.10% - 0.45%). 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.
• Adenosine 0.15% - 0.65% in this moisturizer adds an anti-aging benefit. Adenosine is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical adenosine in low concentrations can help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
