What Dermatologists Say About Removing Dead Skin
The American Academy of Dermatology explains that exfoliation removes dead skin cells from the surface, which can improve texture and help certain products absorb better. Physical exfoliants use granules or tools, while chemical exfoliants use acids or enzymes to dissolve bonds between cells. The AAD notes that the right method depends on skin type, and over-exfoliation can cause irritation, redness, and sensitivity, especially on oily or acne-prone skin.
According to the AAD, people with dry or sensitive skin should choose gentle chemical exfoliants or soft physical methods, while those with oily or thicker skin may tolerate stronger acids or scrubs. The organization warns against using harsh scrubs on broken skin or active acne, and it recommends patch testing new products. For many people, a balanced routine with a mild chemical exfoliant several times a week is enough to address flaking and dullness without damaging the skin barrier.
Top Ingredients and Product Types for Dead Skin
Alpha Hydroxy Acids (AHAs)
Glycolic acid and lactic acid are among the most studied AHAs for dissolving dead skin cells. The AAD lists AHAs as effective for dry, sun-damaged, or rough texture, and they are common in serums, toners, and peels. The Cosmetic Ingredient Review panel has assessed glycolic acid safety in concentrations typically used in leave-on products, and many brands formulate AHAs at 5% to 10% for at-home use.
Beta Hydroxy Acid (BHA) and Enzymes
Salicylic acid, a BHA, is oil-soluble and can penetrate pores, which is why it is often used for oily and acne-prone skin. The U.S. Food and Drug Administration (FDA) regulates salicylic acid in some over-the-counter products, and the American Osteopathic College of Dermatology notes its use for exfoliation and acne. Enzyme-based exfoliants from fruits such as papaya and pineapple offer a gentler option, breaking down dead skin proteins without the abrasion of physical scrubs.
How to Choose and Use an Exfoliator Safely
Dermatologists recommend starting with a low concentration and using exfoliants no more than a few times per week, then adjusting based on tolerance. The Skin Cancer Foundation advises daily sunscreen use because exfoliation can increase sensitivity to UV rays, and it notes that protecting the skin helps maintain results and reduces long-term damage. People with rosacea, eczema, or active inflammation should consult a board-certified dermatologist before starting regular exfoliation.
The American Society for Dermatologic Surgery states that professional treatments such as chemical peels can be tailored to different skin types and concerns, but at-home products require consistent, careful use to avoid irritation. The FDA provides guidance on cosmetic labeling and safety, and it monitors adverse event reports for skincare products. Consumers should look for fragrance-free, non-comedogenic formulas when possible, and they should stop use and seek medical advice if they experience severe burning, blistering, or persistent redness.
