"On whether fruit acid can be used on the lips"

Fruit acid is a commonly used ingredient in skin care. As for whether it can be applied to the lips, it needs to be carefully studied.

The skin of the lips is different from other parts such as the face and neck. Its epidermis is thin, the stratum corneum is also weak, and it lacks the nourishment of sebaceous and sweat glands, so it is more delicate and sensitive.

Fruit acid has the ability to exfoliate, which can promote the metabolism of the skin and make the skin new. However, it is applied to the lips, which may cause many problems. Because of its acidic properties, it may stimulate the delicate skin of the lips, causing tingling, redness and swelling. Long-term or improper use can even cause damage to the lip barrier, making the lips more susceptible to external stimuli, causing dryness and peeling.

If there is only occasional keratin accumulation in the lips, you can try low-concentration fruit acid products cautiously and in small amounts. However, before application, be sure to try it on a small piece of skin on the lips, and wait for a while to see if there is any discomfort. If there is any abnormality, it should be stopped immediately. And the application frequency should not be too high. After application, careful care is required, and lip balm should be applied in a timely manner to moisturize and moisturize.

However, if the lips are already cracked, damaged, or extremely sensitive skin, do not rashly use fruit acid on the lips. The top priority is to repair the lip skin first, and then consider it when it returns to a healthy state.

In short, the use of fruit acids on the lips cannot be generalized. It needs to be done cautiously according to the skin condition of the individual lips to protect the health of the lip skin.
