On the Cause of Fruit Acid Skin Burning
Fruit acid is commonly used in skin care, but sometimes users feel burning pain in the skin. The reason for this is covered by the following numbers.

First, because of the concentration. Fruit acid has preparations of different concentrations. If the concentration is too high, it is applied to the skin. Because of its strong exfoliation and irritation, the skin cannot bear it for a while, so it feels burnt. If high-concentration fruit acid is used in thin parts of the stratum corneum, such as the cheeks, it is often easy to cause discomfort.

Second, the skin tolerance is different. People have different skin tolerances. Sensitive skin, the stratum corneum is thinner, the barrier function is weaker, and it is more sensitive to fruit acid stimulation. Even if the normal concentration of fruit acid suitable for others is used on such sensitive skin, it may cause burning pain. This is because the nerve endings of sensitive skin are more susceptible to irritation and transmit pain signals.

Furthermore, the frequency of use is improper. If the use of fruit acid products is too frequent, the skin fails to repair and adapt, and continues to be irritated. Accumulated, it is easy to cause the skin to be overwhelmed and cause burning pain. If it should be used every few days, but it is used every day, it is difficult for the skin to breathe.

In addition, no pretreatment or follow-up care is done. Before using fruit acid, if the skin is not cleaned, dirt will interact with fruit acid, or affect the effect of fruit acid, and increase the possibility of irritation; after use, if it is not moisturized in time, the skin will lose moisture, the stratum corneum will be damaged, and it will also cause burning pain.

In summary, if you want to avoid the pain of skin burning caused by fruit acid, you should choose the appropriate concentration and frequency of use according to your own skin condition, and do a good job of pretreatment and follow-up care, so that fruit acid can play a skin care effect and avoid skin discomfort.
