On the frequency of application of fruit acid to the skin
The use of fruit acid in skin care is quite critical, but the frequency of application is very particular.

If the skin is healthy and well tolerated, the first use of fruit acid can be applied every seven days. Because the skin is first exposed to fruit acid, it needs to be responded to step by step. Cover the skin's adaptation, like a boat swimming in water, slow will be safe, urgent will be dangerous. After several weeks of adaptation, depending on the state of the skin, gradually increase to every five days.

Those with sensitive skin should be extra cautious. It is advisable to take a small part of the skin and try it first, such as behind the ear or in the elbow, to see if it is uncomfortable. If there is no abnormality, it can be applied to the whole body, and the frequency should be low, and it is appropriate to use it once every half a month. This is because the skin is sensitive and weak, and its power to resist external evil is slightly inferior. If it is used frequently, it may cause redness, swelling and itching.

When applying fruit acid, many matters need to be paid attention to. First, after daytime use, it must be strictly protected against the sun. Fruit acid makes the skin more sensitive to light, and exposure to sunlight can easily cause sunburn and pigmentation. Second, when applying fruit acid, avoid using it with other irritating substances, such as high-concentration alcohol products, strong alkaline cleansers, etc., to avoid overburdening the skin.

In short, the frequency of application of fruit acids to the body and skin needs to be determined according to the characteristics of the individual skin, and it should be done with caution in order to achieve the effect of skin care and avoid the risk of skin damage.
