3. What is Ascorbyl Glucoside AA2G Good for?
Because it is eventually converted into vitamin C in the skin, it inherits all the core functions of VC and has additional advantages due to its characteristics.
a. Outstanding whitening and spot-removing (inhibiting melanin)
(1)Mechanism of action
1)Inhibiting tyrosinase activity: This is a key catalyst in the process of melanin production. VC can interfere with its activity and reduce the production of melanin from the source.
2)Reducing already formed melanin: VC can reduce the already formed, darker "oxidized melanin" to the lighter "reduced melanin", thereby lightening the color of spots and acne marks and brightening the overall skin tone.
(2)Effect: Continuous use can effectively improve uneven skin tone, fade sunspots, age spots and acne marks, and achieve a brighter and fairer overall skin tone.
b. Powerful antioxidant (neutralizing free radicals)
(1)Mechanism of action: When the skin is exposed to ultraviolet rays, pollution and other environments, it will produce a large number of "free radicals", which will attack healthy cells, leading to skin aging, dullness and loss of collagen. VC is one of the most important water-soluble antioxidants in the human body.
Effect:
1)Preventing photoaging: By neutralizing free radicals and reducing the damage of ultraviolet rays to the skin, it serves as an "invisible sun protection" (but cannot replace sunscreen!)" .
2)Anti-inflammatory and soothing: Reduces the inflammatory response caused by oxidative stress and is beneficial for acne-prone and sensitive skin.
3)Protecting other ingredients: Often compounded with antioxidants such as vitamin E, it can enhance each other's antioxidant effects and work together to protect the skin.
c. Promote collagen synthesis (anti-aging)
(1)Mechanism of action: Vitamin C is an indispensable cofactor for the synthesis of collagen. It can activate the enzymes that catalyze the synthesis of collagen (prolyl hydroxylase and lysyl hydroxylase) and stabilize the molecular structure of collagen.
Effect: Continuous use can improve skin elasticity, increase skin firmness, thereby reducing fine lines and wrinkles and delaying signs of aging.
d. Improve rough and smooth skin texture
(1)Mechanism of action: It protects cells through its antioxidant effect and promotes the renewal of healthy skin cells.
Effect: It makes the skin feel smoother and more delicate, and the pores appear smaller visually.
