Medix 5.5 Collagen + Caviar Age Control Moisturizer

Judging from the ingredient list, "Medix 5.5 - Collagen + Caviar Age Control Moisturizer" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Medix 5.5 - Collagen + Caviar Age Control Moisturizer ticks this box. Humectants in this product (acetyl hexapeptide-8, glycerin, butylene glycol 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 (helianthus annuus extract, isopropyl myristate, butyrospermum parkii butter, dimethicone and cetyl alcohol) 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

• We like that this moisturizer contains peptides (acetyl hexapeptide-8 0.40% - 0.65%). 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.
