On the frequency of using glycolic acid on the outside of the femur
for skin maintenance, those who use glycolic acid on the inside of the femur often need to be cautious. The skin on the inside of the femur is more delicate than other parts, so the frequency of using glycolic acid cannot be generalized, and it needs to vary according to the skin type.

If it is oily skin, the sebaceous glands secrete vigorously, and the greasy skin can easily cause pores to clog and cause various diseases. In this case, the frequency of use of glycolic acid can be moderately increased. At the beginning, it can be used every three days to observe the skin's reaction. If the skin is well tolerated and does not show redness, swelling, tingling and other uncomfortable conditions, it can be gradually increased to every two days. However, it should not be used too frequently to avoid damage to the skin barrier

As for dry skin, it is already dehydrated and the stratum corneum is thin. If glycolic acid is used, the frequency should be slowed down. It can be used once a week at the beginning, so that the skin can gradually adapt. After use, it is necessary to replenish water and moisturize in time to prevent the skin from being too dry. After several weeks, if the skin adapts, it can be increased to Tuesday every week.

Neutral skin is between oil and dry, and the state is relatively stable. When using glycolic acid, it can be used every two to three days. However, after each use, it is also necessary to pay attention to the changes of the skin. If there is any discomfort, adjust the frequency immediately.

Sensitive skin, weak epidermis, poor tolerance, and extremely prone to allergies. Use glycolic acid on the inside of the strand with caution. Try it on a small area of skin first, such as behind the ear or inside the elbow, and observe it for 24 hours. If there is no adverse reaction, you can try it on the inside of the strand, and the frequency should not exceed once a week.

Where glycolic acid is used on the inside of the strand, you should pay close attention to the skin's reaction, and adjust the frequency of use in a timely manner to achieve the purpose of maintaining the skin without damaging the health of the skin.
