On the frequency of using glycolic acid in the armpit
The skin of the armpit is delicate. When using glycolic acid, the frequency is particularly critical.

The first use of glycolic acid in the armpit should start at a low frequency. Because the armpit skin is sensitive, if it is used at a high frequency, it may cause discomfort, such as redness, itching, tingling, etc. Generally speaking, once a week is appropriate for the initial stage. This frequency can gradually adapt the skin to the action of glycolic acid and avoid adverse reactions due to excessive stimulation.

After several weeks of adaptation, the frequency can be adjusted appropriately depending on the tolerance of the armpit skin. If the skin has no adverse reactions, it can be gradually increased to twice a week. However, it should be noted that even if the skin is well tolerated, it should not be used too frequently. Excessive use of glycolic acid may damage the barrier function of the armpit skin, resulting in dry and fragile skin, which will increase the risk of skin disease.

At the same time, during the use of glycolic acid, close attention should be paid to the changes of the armpit skin. If there is any abnormality, such as allergic symptoms, skin damage, etc., stop using it immediately and consult a professional dermatologist for advice.

In short, the frequency of using glycolic acid in the armpit needs to be gradually adjusted according to the individual's skin tolerance, in order to achieve the purpose of skin care and maintain skin health.
