When exploring the topic of whether copper peptide and glycolic acid can be used together, the compatibility of the two is crucial. Copper peptide has the effect of promoting collagen production and enhancing skin repair ability. Glycolic acid, as an alpha-hydroxy acid, often plays a role in improving skin quality and rejuvenating skin.

However, when using both, careful consideration is required. Glycolic acid is acidic and may change the local environmental pH, which in turn affects the stability of copper peptide. Due to the stability of copper peptide or the influence of pH, its activity may be reduced under inappropriate pH, which affects skin care efficacy.

In addition, glycolic acid can loosen and thin the stratum corneum of the skin, increasing skin sensitivity. Copper peptides are usually mild, but when the skin is sensitive, they can be used together or cause skin irritation, such as redness, tingling, etc.

Therefore, if you want to use copper peptides with glycolic acid, it is recommended to try it on a small piece of skin first to observe whether there are any adverse reactions. If the skin is well tolerated, you can gradually increase the frequency of use. Or consult a professional dermatologist or skin care expert to get more accurate suggestions according to your skin type to ensure that the skin care process is safe and effective. In this way, you can use both reasonably on the road of pursuing skin beauty to achieve the ideal skin care effect.
