The physical vs chemical exfoliation debate gets framed as a rivalry, but they are two routes to the same destination: removing dead cells from the surface of the skin so it looks smoother and the products applied afterwards can do their job.
Why help a process that happens anyway
Skin renews itself on roughly a 28-day cycle — cells rise, harden and shed without any intervention. That cycle slows with age, and shedding becomes patchy with dryness, smoking or poor sleep. Exfoliation compensates for the unevenness. It is a correction, not a requirement.
Physical exfoliation
Friction: scrubs with abrasive particles, brushes, konjac sponges, peeling gels.
It is cheap, immediate and easy to understand. It is also uneven, and coarse particles cause micro-tears when people press too hard. Reasonable for normal and resilient oily skin. A poor choice for thin, reactive skin or skin with active breakouts — dragging over inflamed areas spreads the problem.
Chemical exfoliation
Acids dissolve the bonds holding dead cells together, so they release without friction.
- AHAs (glycolic, lactic, mandelic) — water-soluble, surface-level, suited to dullness and dryness
- BHA (salicylic) — oil-soluble, gets into pores, the logical pick for oily and congested skin
- PHAs — larger molecules, gentler action, often tolerated by sensitive skin
More even, no micro-tears, and the intensity is adjustable. In exchange you need a proper introduction period and non-negotiable daily sunscreen, since acids increase photosensitivity.
How often to exfoliate
| Skin type | Starting point |
|---|---|
| Oily, resilient | Twice a week |
| Normal | Once or twice a week |
| Dry | Once a week |
| Sensitive | Every 10–14 days, gentle formulas only |
Start at the low end and let your skin set the pace.
Signs you have overdone it
- A tight, shiny surface rather than a healthy glow
- Stinging from products that never stung before
- Flaking, redness, sudden reactivity
- New breakouts appearing during a period of "active" skincare
The fix is to stop exfoliating entirely for two to three weeks and run only gentle cleansing, moisturiser and sunscreen. Adding more products at this stage makes it worse.
Seasons matter too: dry indoor heating in winter is a reason to scale back, not to scrub harder. Faberlic carries both scrubs and acid-based options across its series — see the current catalogue on faberlic.com for what is in rotation. Related routine guides sit in the skincare section.
Exfoliation does not clear acne or remove scarring. See a dermatologist for anything persistent.
