Introduction
The method of exfoliation depends on the thickness and location of the stratum corneum. For thickened stratum corneum on the palms and soles, apply 20% urea cream and cover with plastic wrap, using nightly before bedtime. For mild hyperkeratosis on smooth skin that is not excessively thick, topical application of 10% urea cream or adapalene gel may be used.

What is the correct way to exfoliate?
Exfoliation methods include chemical peels (such as alpha hydroxy acids) and dermabrasion, but the choice of method should be based on individual skin conditions. For dull skin with a thick stratum corneum, low-concentration AHA peels can be effective.
For individuals with sensitive skin and a naturally thin stratum corneum, exfoliation is generally not recommended. The most commonly used exfoliation method—AHA peels—requires careful control of acid concentration. Excessive concentration may lead to over-exfoliation, resulting in skin peeling, redness, reduced resistance to ultraviolet radiation, and even pigmentation.
The proper method of exfoliation involves using medications. Topical keratolytic agents can promote normal skin turnover, such as salicylic acid ointment, high-concentration urea cream, tretinoin cream, or oral retinoids for exfoliation. Avoid using hot water scalding or physical methods such as scraping with a blade, as these cause unnecessary physical or chemical irritation.
If hyperkeratosis recurs, patients should visit the dermatology department at a reputable hospital, where a dermatologist can perform a thorough evaluation, identify the underlying cause of excessive keratinization, and provide appropriate treatment.
