ROUND LAB Birch Juice Moisturizing Sun Stick

"ROUND LAB - Birch Juice Moisturizing Sun Stick" has a good moisturizing formula. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (acetyl hexapeptide-8, hexapeptide-9, glycerin, glyceryl glucoside and hyaluronic acid) 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). Palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, tripeptide-1, oryza sativa bran oil and vinyl dimethicone in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

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 (0.20% - 0.40%) it cannot have a noticeable benefit for the skin.
• This moisturizer also contains Peptides (hexapeptide-9 0.20% - 0.40%, palmitoyl hexapeptide-12 0.25% - 0.40%, palmitoyl pentapeptide-4 0.20% - 0.40%, palmitoyl tripeptide-5 0.20% - 0.40%, palmitoyl tripeptide-1 0.25% - 0.45%, palmitoyl tetrapeptide-7 0.25% - 0.45%, tripeptide-1 0.25% - 0.45%, copper tripeptide-1 0.20% - 0.40%, acetyl hexapeptide-8 0.20% - 0.40%, dipeptide diaminobutyroyl benzylamide diacetate 0.20% - 0.40% and nonapeptide-1 0.20% - 0.40%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, 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 they are helpful. Peptides 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 0.20% - 0.40%. It 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 somewhat 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).
