On the Advantages and Disadvantages of Sharing Glycolic Acid and Salicylic Acid
Glycolic Acid and Salicylic Acid are both commonly used acids for skin care. Modern people have a good idea of exploring whether the two can be used together to achieve better skin care effects.

Glycolic Acid is an alpha-hydroxy acid, which has a small molecule and can easily penetrate into the stratum corneum of the skin, promote the metabolism of keratinocytes, and make the skin's surface old and waste exfoliation, which in turn makes the skin smoother and more delicate, and also has an effect on brightening the complexion and improving dullness.

Salicylic acid is a beta-hydroxy acid, which is lipophilic. It can penetrate deep into the pores, dissolve oil, and remove corneal plugs that block pores. It has a good conditioning effect on skin problems such as acne and acne, and can also reduce skin inflammation.

If the two are used together, they can theoretically complement each other. Glycolic acid improves the surface texture of the skin, and salicylic acid targets the internal cleansing and inflammation of the pores, which seems to improve the skin condition in an all-round way. For oily and thick-skinned skin with acne, it may play a synergistic effect, not only cleaning pores, but also accelerating the renewal of old waste keratin.

However, using both also carries risks. These two acids are both irritating to the skin, and when shared, this irritation may be superimposed. Those with sensitive skin may experience redness, tingling, itching, and even discomfort symptoms such as desquamation. Long-term overuse may also damage the skin barrier, reduce the skin's ability to resist external stimuli, and make it more susceptible to environmental factors, causing many skin problems.

Therefore, those who want to use glycolic acid and salicylic acid to share must first check their skin conditions. Those with strong skin tolerance can try it cautiously under the premise of strictly following the usage specifications. Initially, it should be tried on a small scale and at a low concentration. After the skin adapts, gradually expand the scope of use and increase the concentration. If the skin feels uncomfortable during use, stop using it immediately and seek professional help. Only in this way can we ensure skin health while pursuing skin beauty.
