Discussion on whether glycolic acid and psoralen can be used together. The combination of chemical agents is the key to skin care. Glycolic acid and psoralen have unique effects in the field of skin care, but whether they can be used together is the focus of everyone's attention.

Glycolic acid is an alpha-hydroxy acid with excellent exfoliation function. It can loosen the connection between keratinocytes, shed the old stratum corneum, promote skin metabolism, make the skin surface smoother and more delicate, and can stimulate collagen production, improve skin texture and elasticity.

Psoralen is a natural plant extract with relatively mild properties. Its functional retinoic acid can regulate cell differentiation, promote collagen and elastic fiber synthesis, effectively reduce wrinkles, improve skin uneven color and other problems, and low allergenicity, suitable for a variety of skin types.

Discussing the compatibility of the two, from the perspective of chemical properties, glycolic acid is acidic, while psoralen has a stable chemical structure, and generally no chemical reaction occurs between the two. However, in practical application, caution is still required. Due to the exfoliation of glycolic acid, the skin barrier will be temporarily weakened. At this time, if the combination of psoralen is used, although there is no chemical conflict in theory, the skin may be irritated by two active ingredients for a short time, causing discomfort, such as redness and tingling.

Therefore, those with strong skin tolerance can try it on a small area of skin first, observe no adverse reactions, and then gradually expand the scope of use. However, for those with sensitive skin, it is advisable to consult a professional before using it, or use it separately. After the skin adapts, try to use it together, and pay close attention to the skin reaction, and adjust the frequency and dose of use in a timely manner to achieve safe and effective skin care purposes.
