How to whiten after sun repair

Eat more fresh fruits and vegetables, especially those rich in VC such as broccoli, cabbage, carrots, tomatoes, lemons, strawberries, kiwis, etc., or appropriately supplement with some foods that can help even out skin tone and accelerate skin healing, such as: lily, mung beans, white fungus, lotus seeds, coix seeds, etc.; as well as nuts such as almonds, walnuts, and sesame seeds.

What ingredients can whiten

VC and its derivatives

This seems to be an ingredient that everyone can think of, and it is also very safe. VC and its derivatives can break down melanin in the skin, promote the production of skin collagen, and reduce inflammatory spots. Taking VC orally also has a whitening effect, but it may be unstable when used in skin care products, so scientists have developed various VC derivatives such as L-ascorbic acid for whitening.

Fruit acid

Fruit acid is an organic acid extracted from fruits. The most commonly used one is glycolic acid extracted from sugarcane. It improves skin tone by removing aging keratin cells, and it must reach a certain concentration. However, the product ingredient list will not tell you the concentration, and for sensitive skin, fruit acid may cause excessive irritation and is more suitable for oily skin with a thicker stratum corneum.

Arbutin

Arbutin is extracted from the bearberry plant and reduces the synthesis of melanin by inhibiting the production of tyrosinase. Arbutin has a high safety factor at a concentration below 7% and has a good whitening effect.

Licorice Extract

Licorice extract improves hyperpigmentation and reduces the generation of free radicals by dispersing melanin and inhibiting the biosynthesis of melanin and cyclooxygenase respectively. However, the effect of improving pigmentation needs further verification.
