Exfoliation refers to the process of removing dead cells from the skin's outermost layer (stratum corneum), either through chemical agents (such as AHAs/BHAs) or physical means. This promotes smoother texture, improved radiance, and enhanced penetration of other topical products.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation or stinging | Common | Transient redness, tingling, or burning, especially with chemical exfoliants or higher concentrations. |
Dryness or flaking | Common | Over-exfoliation can disrupt the skin barrier, leading to dryness and peeling. |
Increased photosensitivity | Common | Particularly with AHAs; sun protection is recommended during use. |
Post-inflammatory hyperpigmentation | Uncommon | More likely in darker skin tones, especially after aggressive physical or chemical exfoliation. |
Contact dermatitis | Uncommon | Allergic or irritant reactions to specific exfoliating agents. |
Chemical burns | Rare | Associated with high-concentration acids or prolonged contact times. |
Scarring | Very rare | Typically linked to improper use of strong peels or physical abrasion. |
