Recognised for its antioxidant power, astaxanthin is a fat-soluble pigment belonging to the carotenoid family. Found in unicellular microalgae, it helps combat signs of skin ageing. Generally well tolerated and without notable side effects, this active ingredient can be mixed with other substances to amplify its benefits. Let's discover them together.
Astaxanthin: Which other active ingredients should it be combined with?
Association No.1: Astaxanthin and Carotenoids.
Theastaxanthin is known for its strong antioxidant power. Its effectiveness increases when it is combined with other carotenoids, particularly beta-carotene, lycopene, lutein or even zeaxanthin.
Association No. 2: Astaxanthin and Vitamin E.
The Vitamin E (INCI: Tocopherol) was first identified in 1922. It is a fat-soluble compound and an essential component of sebum. When applied to the skin, it has antioxidant properties to combat oxidative stress. A study has shown that astaxanthin is capable of acting in synergy with Vitamin E to enhance its antioxidant power.
This combination of active ingredients is particularly beneficial for acne-prone skin. Indeed, dysseborrhea is characterised by a problem with the composition of sebum, notably a deficiency in vitamin E. This is a vitamin that protects squalene, one of the constituents of sebum, from its oxidation into lanosterol by free radicals.
Indeed, this change in composition results in a modification of the sebum's texture, which then becomes thick and eventually clogs the pores, promoting the appearance of spots or blackheads. This synergy of active ingredients could help to compensate for the vitamin E deficiency and prevent the oxidation of squalene, allowing for the recovery of sebum with a normal texture and limiting the formation of spots or comedones.
Association No. 3: Astaxanthin and Hyaluronic Acid.
Derived from the fermentation of wheat, hyaluronic acid is known for its highly hydrating properties. Indeed, it can retain up to a thousand times its weight in water. However, the body's production of hyaluronic acid tends to decrease with age, leading to the appearance of the first fine lines on the skin's surface. The application of hyaluronic acid helps to reduce the appearance of fine lines and make the skin more supple and toned. Clinical studies have also shown that astaxanthin can prevent skin dehydration. Working in synergy, they combat the signs of skin ageing and thus prevent skin dehydration.
Association No. 4: Astaxanthin and plant extracts rich in polyphenols.
Polyphenols are a family of molecules that plants naturally produce for their defence. These are potent antioxidants capable of neutralising free radicals. Certain plant extracts are particularly rich in polyphenols, notably thered ginseng extract, thekale extract, rosemary extract or even the tagetes extract.
We have made the decision to combine astaxanthin (INCI: Haematococcus Pluvialis Extract) with two plant extracts rich in polyphenols in our antioxidant face cream : the ginseng extract (INCI: Panax Ginseng Root Extract) and the kale extract (INCI: Brassica Oleracea Acephala Leaf Extract) rich in sulphur. Thanks to this combination of botanical actives, this cream helps to combat the free radicals responsible for dull complexion and premature skin ageing.
