Function of botanical extracts in cosmetics
1) Whitening plant extracts: The whitening effect of arbutin is remarkable. It can quickly penetrate into the skin. Without affecting the proliferation concentration of skin cells, it can effectively inhibit the activity of tyrosinase in the skin, so as to block the formation of melanin and reduce skin pigment deposition and remove color spots and freckles. In addition, arbutin does not produce toxic, irritating, allergic and other side effects on pigment cells, and it also has skin moistening, wound healing, bactericidal and synergistic anti-inflammatory effects. Arbutin is one of the most popular whitening materials abroad. Mulberry pigment has certain antioxidant and free radical scavenging effects. Mulberry pigment extract can inhibit lipid peroxidation, improve the blood supply of the skin, nourish the skin, make the skin white, tender, and delay aging. Flavonoids, such as licorice flavonoids, which can effectively eliminate free radicals in the skin or inhibit the activities of various enzymes in the process of melanin formation, thus promoting metabolism, reducing melanin deposition and moistening the skin.
2) Anti-aging plant extracts: With the increase of free radicals in the body, the skin begins to show an aging state. Therefore, scavenging excessive free radicals in the body is an important way of anti-aging. Plant polyphenols and flavonoids are typical free radical scavengers. Common polyphenols include tea polyphenols, grape polyphenols, peel polyphenols, etc. Plant polyphenols have antioxidant, free radical elimination, and can also achieve whitening effect by absorbing ultraviolet light. By inhibiting tyrosinase and peroxidase, plant polyphenols can inhibit the secretion of melanin, reduce skin myelinizations, freckles, brown spots and age spots. Flavonoids have the function of superoxide dismutase activity and scavenging free radicals, which can repair damaged skin, resist lipid oxidation and anti-aging.
3) Moisturizing and repairing skin plant extracts: There are quite a few plant extracts with the effects of moisturizing, such as aloe, seaweed, olive, chamomile and other extracts. For example, hyaluronic acid (HA) extracted from aloe is a plant moisturizing and soothing agent. Studies have shown that the carboxyl group and other polar groups in HA molecules can form hydrogen bonds with water to combine a large amount of water, thus playing a role in water conservation in skin tissues. This water-based colloidal matrix makes the skin soft, elastic and smooth. HA can also promote the proliferation and differentiation of epidermal cells, prevent and repair skin damage.
