"On the Compatibility of Glycolic Acid and Copper Peptide"

The compatibility of glycolic acid and copper peptide is really important for skin care efficacy. Glycolic acid is active, has the ability to exfoliate and promote cell renewal, and is often a good product for skin rejuvenation. Copper peptides are known for stimulating collagen production and repairing skin damage.

However, whether the two can be used together remains to be seen. Glycolic acid is acidic and has a low pH value, while copper peptide can survive and play an effective role in a specific acid-base environment. If the two are used together, the acidic nature of glycolic acid or the structural variation of copper peptide will impair its activity. The stability of copper ions in copper peptide is easily affected by pH. In case of strong acid, a chemical reaction may occur, resulting in the impairment of its original effect.

And the skin's tolerance to both also needs to be considered. The stimulation of glycolic acid may weaken the skin barrier for a short time. At this time, if copper peptide is used in combination, it may increase the burden on the skin and cause discomfort, such as redness and tingling.

However, studies have shown that if properly prepared, the concentration and the timing of use can be controlled, and the two can also complement each other. For example, first condition the skin with low-concentration glycolic acid. After the skin adapts and exfoliates moderately, then use copper peptide, or use the channel opened by glycolic acid to make copper peptide more easily penetrate the skin and exert its repair ability.

To sum up, the compatibility of glycolic acid and copper peptide has both opportunities and challenges. Users should be cautious and carefully observe the skin's reaction in order to take advantage of advantages and avoid disadvantages and achieve the best skin care.
