BIOTHERM Blue Therapy Red Algae Cream

Judging from the ingredient list, "BIOTHERM - Blue Therapy Red Algae Cream" works well for improving skin hydration 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

• This moistruizer also contains peptides (palmitoyl tripeptide-1 0.30% - 0.55% and palmitoyl tetrapeptide-7 0.30% - 0.55%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of peptides is, but it is very likely that peptides in skincare are helpful. They might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
• Adenosine 0.25% - 0.45% in this product adds an anti-aging property to it. Adenosine is a chemical present inside our skin cells. A clinical trial confirmed that topical application of adenosine in a low concentration reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where we our mimic is the most active, for example, in the corners of the eyes or on the forehead).
