On the compatibility of glycolic acid and peptide
The compatibility of glycolic acid and peptide, the nature of the two is related to whether the compatibility is appropriate, and both doctors and beauty lovers value it. Glycolic acid belongs to the class of fruit acids, which are active in nature and play a significant role in exfoliation and metabolism promotion of the skin. It is often the choice for skin rejuvenation and beauty. Peptides, which are condensed from amino acids, have a variety of physiological activities, such as skin repair and collagen synthesis promotion.

However, when the two are used together, their compatibility must be reviewed. Glycolic acid is a mild acid, and its effect on the stratum corneum of the skin may be different from the transdermal absorption of peptides. The structure of peptides is diverse, or its activity is changed due to the acid environment of glycolic acid. If the structure of the peptide dissolves in contact with acid, or the spatial conformation changes, its biological activity may be reduced or lost.

Looking at various experiments and clinical practices, some peptides can retain their activity in the presence of glycolic acid. Due to the stable structure of the peptide, the acid environment is not enough to break its key chemical bonds. However, there are also peptides, which experience glycolic acid, and their activity decreases rapidly. For example, some oligopeptides, the amino acid residues in their sequences are sensitive to acids, and the slightly changed environment of glycolic acid makes their activity impaired.

And glycolic acid makes the skin barrier temporarily change, at which time the peptide may be more likely to enter the skin. Although this is beneficial, there are also disadvantages. It may cause skin irritation and cause discomfort. Therefore, when using a mixture of the two, it is necessary to At the beginning of use, it is recommended to test it at a low concentration, observe the skin's reaction, and gradually adjust the concentration and frequency to ensure full effectiveness.

In general, the compatibility of glycolic acid and peptide has advantages and disadvantages. Users should use it cautiously according to the characteristics of the skin and peptide, in order to take advantage of it and avoid its harm, and achieve the best condition of skin care.
