On when glycol acid takes effect
When glycol acid is used on the skin, everyone wants to know when it takes effect. The effect of this acid is not achieved overnight, but is related to many things.

One is related to the skin type. If the skin is greasy and thick, the stratum corneum is slightly thicker, and the infiltration of glycol acid is slightly slower, and the effect may take a long time. At the time of initial use, or after ten days, the skin will feel slightly moist and slightly uniform in color. If the skin is delicate and thin, the stratum corneum is thin, and glycol acid is easy to enter the skin, or within a few days, the skin has changed, or the skin may feel soft, or the color may be bright.

Second, depending on the concentration. Low concentrations, such as 2% - 5% glycolic acid, are mild in nature, but their strength is slightly weaker. Those who use it are mostly those who are new to this type of acid. When using it for the first time, or more than half a month, the texture of the skin gradually feels fine and shiny. High concentrations, such as 10% - 20%, work quickly. Use with caution, suitable for those who are used to brushing acid. Use it properly, or about a week, you can see significant changes. If there are fewer acne, the skin tone is bright.

Third, it is related to usage. If you apply it thinly on time, use it every day or every day, step by step, and its effect will gradually appear. Or when starting to use, the skin needs to be adapted, and the effect will be slightly felt in half a month, and then it will become more and more obvious. If it is a high-concentration product, the method of fruit acid skin change will be performed. Under the operation of a professional, the effect will appear immediately. In a few days, the skin will be rejuvenated, and then you need to be careful in the future.

Yes, when glycolic acid takes effect, your mileage may vary, depending on the skin, and vary from method to method. Users should carefully observe themselves, step by step, in order to obtain the best effect and get the joy of skin rejuvenation.
