Does the skin need exfoliation?

In general, whether the skin needs exfoliation mainly depends on its actual condition. If the skin is relatively thin, exfoliation is usually unnecessary; if the skin is thicker, exfoliation may be needed. The detailed analysis is as follows:

When the skin is thin, its outer stratum corneum (outermost layer) is already relatively thin and sufficiently translucent, allowing light to pass through and reflect the skin's natural glow. In such cases, exfoliating may damage the skin’s natural protective barrier, increasing sensitivity and making it more vulnerable to external irritants such as UV radiation and pollutants. This can lead to discomfort including redness, stinging, or irritation. Moreover, exfoliating thin skin may accelerate aging, making fine lines and sagging more likely.

When the skin is thicker, the stratum corneum tends to be thicker as well, which may hinder normal skin metabolism and nutrient absorption. In these cases, exfoliation helps remove dead skin cells from the surface, resulting in smoother, softer skin and improved absorption of skincare products. Additionally, exfoliation can help address dullness and rough texture, giving the skin a brighter, more radiant appearance.

If exfoliation is needed, it is recommended to visit a reputable medical facility and undergo chemical peels such as glycolic acid (alpha-hydroxy acid) peels under the guidance of a qualified physician. Glycolic acid peels use high-concentration acids to promote shedding of the aged keratinized layer, accelerate new cell regeneration, and stimulate collagen and elastic fiber production in the dermis, thereby achieving skin brightening, fading pigmentation, and improving overall complexion. The typical cost reference for glycolic acid peels ranges from 2,000 to 12,000 yuan per session. Results are generally noticeable around two weeks after treatment, although side effects such as peeling may occur.
