The comparison between glycolic acid and arbutin
Fuglycolic acid and alpha-arbutin are both commonly used agents for skin care, and their performance and effect are different, which is quite important to users.

Glycolic acid belongs to the class of fruit acids, and its molecules are small and can quickly penetrate the stratum corneum of the skin. Its main function is to promote the shedding of keratinocytes, accelerate the renewal of the skin surface, make the skin glow, and gradually disappear the roughness. And it can stimulate the synthesis of collagen in the dermis, which has the effect of improving fine lines and relaxation. However, it is more intense, and those with sensitive skin use it, or cause redness and itching. It needs to be used cautiously at the beginning, starting from low concentration and gradually increasing the dosage.

Alpha-arbutin is long for suppressing blackness. It can block the activity of tyrosinase, reduce the production of melanin, and then lighten spots and whiten, making skin tone even. Its sex is mild, and it is more suitable for all kinds of skin, that is, sensitive skin can also accept it. However, the effect is slightly slower, and it needs to be used for a long time to see significant effect.

If you want quick skin rejuvenation and strong skin tolerance, glycolic acid may be a good choice; if you want gentle whitening, especially for sensitive skin, alpha-arbutin is more suitable. Users should choose it carefully according to their skin type and desired effect, in order to achieve the best condition of skin care.
