Astaxanthin to combat free radicals due to its antioxidant power.
Thanks to its antioxidant property, astaxanthin is a skin ally. It is a major nutrient that combats premature skin ageing by fighting free radicals. These free radicals damage molecular structures, including DNA, proteins, lipids, etc. Free radicals are promoted by certain external factors such as stress, the environment, or sunlight.
Indeed, exposure to the sun triggers the activity of a series of enzymes that notably cause the degradation of collagen and elastin, the proteins responsible for the elasticity and firmness of the skin. As a result, reinforced by these free radicals, the enzymatic activity leads to the appearance of the first signs of ageing. Due to its antioxidant action, astaxanthin has the ability to capture free radicals and prevent their overproduction, which is the cause of oxidative stress.
It should be noted that astaxanthin protects the skin from sun exposure, but it does not replace sun protection care.
Astaxanthin is a favoured active ingredient in skincare for combating free radicals. Indeed, the accumulation of free radicals accelerates the process of skin ageing. Thanks to its 13 conjugated polyunsaturated double bonds, it can eliminate high-energy electrons. Its amphipathic structure gives it an affinity for both water and lipids, allowing it to insert itself into the bilayers of cell membranes and limit the damage caused by lipid peroxidation. Indeed, lipid peroxidation is responsible for tissue damage due to the formation of free radicals. By capturing these free radicals, astaxanthin protects the skin from tissue ageing and reduces the appearance of wrinkles.
Astaxanthin protects the skin from ageing.
The potent and unique antioxidant power of astaxanthin rests on its ability to cross the cell membrane. Indeed, it possesses both lipophilic and hydrophilic properties. It can combine with the cell membrane from both the inside and the outside. Due to its chemical structure, its polar groups overlap the polar regions of the cell membrane, while the central non-polar area of the molecule inserts itself into the internal non-polar region of the membrane.
Thus, astaxanthin can take a transmembrane alignment in biological membranes, helping to maintain membrane structure and reduce membrane fluidity. This property allows it to act as a cellular shield to combat free radicals.This feature thus protects the entire cell against skin ageing.
Astaxanthin for preventing skin dehydration.
Two studies have measuredthe effects of a topical application of astaxanthin on skin ageing. After three weeks of topical applications of 280 mg/day of astaxanthin cream,the moisture content was significantly increasedby 3.32%. Improvements in skin dryness and itching were also reported.
The second study reveals a 106.67% increase in skin water content after two weeks of applying 140 mg/day of astaxanthin-based cream in participants with dry and combination skin. Thus, these studies have demonstrated that astaxanthin could improve skin hydration although its mode of action is not known.
Astaxanthin for skin firming.
A study has revealed that astaxanthine is capable of stimulating collagen production, a protein responsible for skin elasticity, the production of which decreases with age. Indeed, it is capable of increasing the level of TIMP-1 inhibitor, which reduces the level of matrix metalloproteinases and boosts collagen production.
Present in the form of fibres, collagen is naturally found in the dermis. It ensures tissue regeneration, provides them with high elasticity, as well as great resistance. It acts as a binder between the skin cells, which helps to maintain its structure. By promoting its production, astaxanthin allows the skin to regain its elasticity and firmness.
Utilising astaxanthin to soothe the skin due to its anti-inflammatory properties.
It has been demonstrated that astaxanthin reduces the levels of matrix metalloproteinases (MMP) and pro-inflammatory cytokines. It inhibits the activity of IκB kinase, a complex responsible for controlling the activation of NF-κB. This keeps NF-κB, a pro-inflammatory signalling pathway, inactive within the cellular cytoplasm, thereby allowing toreduce inflammations caused, for example, by skin diseases and to soothe the skin.
The astaxanthin found in our antioxidant face cream.
Aware of the numerous benefits provided by astaxanthin, we have chosen to incorporate it into the formulation of our antioxidant face cream. Along with thekale extract (INCI: Brassica Oleracea Acephala Leaf Extract) and thered ginseng extract (INCI: Panax Ginseng Root Extract), it delivers numerous beneficial effects on the skin.
It protects the skin from external aggressions (pollution, UV rays...);
It prevents wrinkles and fine lines;
It hydrates the skin;
It slows down the premature ageing of the epidermis;
It enhances the skin's firmness.
