On the method of using glycolic acid after AHA and BHA
for skin care, AHA and BHA are often the choice for skin rejuvenation. After using AHA and BHA, it is doubtful whether glycolic acid can be used again.
AHA, α-hydroxy acid is also mostly derived from fruits, so it is also called fruit acid. It can loosen the connections between keratinocytes, make the old waste keratin on the surface of the skin fall off, make the skin smooth and delicate, and can stimulate the production of collagen in the dermis, which has the power of skin rejuvenation. BHA is salicylic acid, which is lipophilic, can penetrate deep into pores, clean oil, improve acne, acne, and is anti-inflammatory.
Glycolic acid also belongs to the AHA family. It is the smallest molecular fruit acid and has good penetration. After using AHA and BHA, the stratum corneum of the skin has changed. If glycolic acid is used at this time, the state of the skin needs to be reviewed. If the skin has strong tolerance, and AHA and BHA do not experience discomfort after use, such as redness, tingling, desquamation, etc., you can try glycolic acid cautiously. Apply it on a small area first to check the skin reaction. If the skin is no different, you can gradually expand the scope of application.
However, if the skin is sensitive after using AHA and BHA, such as redness and burning, at this time, use glycolic acid slowly. It is advisable to wait for the skin to return to normal, and then consider it again. When covering the skin for sensitivity, the barrier is damaged. Although glycolic acid is beneficial, it may aggravate irritation and exacerbate skin problems.
In short, using glycolic acid after AHA and BHA should be based on skin tolerance and careful to ensure skin health and achieve skin care effects.
