For most people in Bangladesh's climate: 2–3 times a week is plenty. Daily chemical exfoliation is too much for almost everyone and is the fastest way to damage your skin barrier.
| Skin type | How often |
|---|---|
| Sensitive / dry | 1× per week (start with PHA, the gentlest) |
| Normal / combination | 2× per week |
| Oily / acne-prone | 2–3× per week (BHA suits you best) |
AHA vs BHA — which one?
- AHA (glycolic, lactic acid): works on the *surface* — brightens, smooths texture, fades dullness and dark spots. Best for dry/normal skin. (AHA guide)
- BHA (salicylic acid): oil-soluble, goes *into* the pore — clears blackheads and acne. Best for oily/acne-prone skin. (BHA guide)
- PHA: the gentlest, for sensitive skin.
You usually only need one exfoliating acid in your routine — not all three.
Signs you are over-exfoliating
- Tight, shiny, or "too smooth/waxy" skin
- New stinging when you apply other products
- Redness, flaking, or sudden breakouts
- Skin feels more sensitive to sun
If you see these, stop all acids for 1–2 weeks and focus on a gentle cleanser, moisturizer and sunscreen until the barrier recovers.
The rules
1. Exfoliate at night, never the same night as retinol.
2. Always wear sunscreen the next morning — exfoliated skin burns faster.
3. Don't stack an exfoliating cleanser + exfoliating toner + a peel — pick one acid step.
