Whether glycolic acid and peptide serum can be used together for
skin protection, the appropriate combination of the products used, whether it is related to efficacy and skin safety. The combination of glycolic acid and peptide serum is quite popular.

Glycolic acid is a fruit acid or the like, its molecules are small, and can quickly penetrate the stratum corneum of the skin. With the ability to exfoliate, it can make the old waste exfoliation fall off, make the skin surface renewed, radiant, and can stimulate the production of collagen in the dermis, making the skin firm and elastic. However, its nature is more lively, if used improperly, it may cause sensitive, redness, and tingling skin.

Peptide serum contains a variety of active polypeptides. Peptides are small molecules composed of amino acids, which can simulate the natural signals of the human body, stimulate cell activity, promote the synthesis of collagen and elastic fibers, strengthen the skin support structure, and achieve the effect of anti-wrinkle and firming; they also have anti-inflammatory and soothing effects, which can protect the skin and stabilize.

As for whether the two can be used together, it is time to analyze them in detail. Glycolic acid thins the stratum corneum of the skin and increases its permeability, and peptide serum is easier for the skin to absorb. However, glycolic acid may cause skin sensitivity to increase in a short period of time. If used in combination with peptide serum at this time, some active ingredients in the peptide may exacerbate skin discomfort.

Therefore, if you want to use glycolic acid and peptide serum together, it is necessary to test the skin's tolerance first. Take a small amount of glycolic acid products, apply them behind the ear or on a small piece of facial skin, and observe 24-48 hours. If there is no redness, swelling, itching and other discomfort, you can try it. For the first time, it is advisable to use low-concentration glycolic acid products and peptide serum at different times, such as peptide serum in the morning and glycolic acid products later. And the frequency of use increases gradually, and observe the skin's reaction. If the skin is sensitive or uncomfortable, stop and consult a professional dermatologist or beautician.

In short, skin care methods, your mileage may vary, product matching must be cautious, to protect skin health as the first priority.
