On the compatibility of peptides and glycolic acid
The key to skin care is the compatibility of ingredients. Peptides have the ability to repair the skin and promote collagen growth; glycolic acid is a fruit acid, which can rejuvenate, exfoliate and change the skin. Both are effective when used alone, but when used together, the compatibility of them is not negligible.

Peptides are mostly chain-like structures composed of amino acids, which are soft or sensitive in nature. Glycolic acid, acidic, can dissolve keratin, pass pores, and make skin smooth. However, its acidity may also affect the structure and activity of peptides.

From the chemical analysis, the acidic environment of glycolic acid, some amino acid residues or protonation in peptides, cause peptide chain conformational changes and reduced activity. And high concentrations of glycolic acid or peptide hydrolysis, break its structure and lose its efficacy.

However, under appropriate conditions, the two can also be compatible. If the concentration of glycolic acid is controlled in a mild range, when the concentration is low, it has little effect on the peptide, and the two can achieve better skin care effect. First use the peptide to nourish the muscle base, and then use the glycolic acid to rejuvenate the skin, or use it in time-sharing, can avoid its conflict and take advantage of its strengths.

In general, peptides are compatible with glycolic acid. When observing the differences in concentration, order and skin type. Use it well, it can bring out the brilliance of the skin; if you are not careful, it may damage the skin. Therefore, users should be cautious, according to their own skin shape, explore the beauty of combining the two, and achieve the maintenance of the skin.
