BIOTHERM Blue Therapy Red Algae Uplift Day Firming Rosy Cream

Based on the ingredients included, "BIOTHERM - Blue Therapy Red Algae Uplift Day Firming Rosy Cream" works well for moisturizing the skin. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin, sodium lactate, rhamnose, 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 (palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, dimethicone, cetearyl alcohol 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 (palmitoyl tripeptide-1 0.30% - 0.55% and palmitoyl tetrapeptide-7 0.30% - 0.55%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, 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 0.25% - 0.45%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
