Exfoliation is the removal of dead cells from the outermost layer of the skin (stratum corneum). Your skin naturally sheds dead cells roughly every 28 days, but this cycle slows with age, sun damage, and hormonal changes — leading to dull, rough, or congested skin. Exfoliation accelerates this process.
Physical vs. Chemical Exfoliation
Exfoliation Methods
| Physical | Chemical | |
|---|---|---|
| How It Works | Abrasion (scrubs, brushes, devices) | Dissolves bonds between dead cells (acids, enzymes) |
| Examples | HydraFacial vortex tip, dermaplaning | Glycolic acid, salicylic acid, lactic acid peels |
| Best For | Surface-level smoothing | Deeper exfoliation, acne, pigmentation |
| Risk of Over-Exfoliation | Higher if too aggressive | Lower with professional calibration |
⚠️ ImportantOver-exfoliation is real. Signs include redness, increased sensitivity, breakouts, and a waxy skin texture. If you're using a HydraFacial or chemical peel professionally, scale back your at-home exfoliation to 1–2 times per week max.
