Exfoliation refers to the removal of dead skin cells (corneocytes) from the surface of the skin, either through chemical agents (such as alpha- and beta-hydroxy acids or enzymes) or physical/mechanical means (such as scrubs). This process can improve skin texture, unclog pores, and promote a smoother, brighter appearance.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation, redness, or stinging | Common | Especially with chemical exfoliants or over-exfoliation; usually transient. |
Dryness and flaking | Common | Removal of the outer barrier can reduce moisture retention. |
Increased photosensitivity | Common | Particularly with AHAs; sunscreen use is advised. |
Microtears or abrasion | Uncommon | More associated with harsh physical/mechanical exfoliants. |
Post-inflammatory hyperpigmentation | Uncommon | Can occur in darker skin types after irritation or aggressive exfoliation. |
Contact dermatitis or allergic reaction | Rare | Reaction to specific exfoliating agents or additives. |
Chemical burns | Rare | Linked to high-concentration acids or prolonged contact. |
