On whether fruit acid is suitable for AHA-BHA skin rejuvenation
Those who are good skin protectors in the world often use AHA and BHA to rejuvenate the skin, hoping to exfoliate old exfoliation, make the skin new and radiant. However, there are different opinions on whether glycolic acid can be used after surgery. Here is a discussion.

AHA and BHA are both exfoliators. AHA is mostly derived from fruits, which can penetrate deep into the skin, dissolve the bonds between the cuticles, and make the stratum corneum fall off; BHA is lipophilic and can penetrate deep into the pores, clean sebum, and unclog pores. After the two skin rejuvenation, the skin is temporarily sensitive, the stratum corneum becomes thinner, and the defense is slightly weaker.

Glycolic acid is a kind of AHA, with small molecules and strong penetration. If it is used immediately after AHA-BHA rejuvenation, the skin may be overwhelmed. The skin has been rejuvenated for the first time and needs time to be repaired. At this time, the strong penetration of glycolic acid may cause skin tingling, redness and swelling, and even cause allergies.

However, if after rejuvenation, after several days of recuperation, the skin has no abnormalities. At this time, using glycolic acid is also beneficial. It can continue to promote keratin renewal, improve skin texture, and increase skin radiance. But use it carefully and try it before a small area of skin to see if there is any discomfort. And the starting concentration should be low, gradually increase, so that the skin can adapt.

In summary, after AHA-BHA rejuvenation, glycolic acid should not be used rashly. It depends on the recovery of the skin. When the skin is stable and used in a cautious manner, it can be used for skin care and avoid the risk of skin damage.
