Exfoliation Frequency
The skin problems people blame on their moisturiser are usually over-exfoliation. Acids and scrubs aren't the villain; how often you use them is. The bottle says daily. The right answer for almost everyone is one exfoliant, one to three nights a week, in the evening. Below that line you get smoother texture and more even tone within a month or two. Above it, the same products quietly take your barrier apart and make everything else in the routine sting.

Your skin already sheds itself every 14 to 45 days, depending on age and body site 1. Exfoliation just hurries the last step. AHAs (glycolic, lactic, mandelic) dissolve the glue between dead cells; salicylic acid is oil-soluble, so it clears clogged pores, which is why it's the acne acid. The limit is that your skin only makes new cells so fast. Strip layers faster than the base replaces them and the barrier goes thin and leaky — that's when the moisturiser you've worn for years starts to sting.

Inside the window, acids build skin; they don't wreck it. Six months of an AHA lotion left forearm skin about a quarter thicker with denser collagen and no inflammation 2. Salicylic acid beats placebo on acne, clearing the closed comedones you can't pop 3, and gets a guideline nod as a well-tolerated leave-on active 4. Gluconolactone matches glycolic with less stinging 5. The honest gap: the weekly cadence is calibrated from tolerability, not a head-to-head trial.

One acid, one to three nights, and let your skin set the number.

The first payoff is subtle; the second is that everything else works. Inside a month, makeup sits better and skin stops looking dull under harsh light. By six weeks, people say you look less tired without knowing why. Over six months to a year, skin gets visibly fuller and fine lines soften, the same direction the forearm histology took 2. The quiet bonus: at the right cadence, retinol stings less and your other actives absorb more evenly. The same three minutes run daily gives you the opposite skin.

The fine print — when to skip it, and what people get wrong

Over-exfoliation rarely announces itself. The tell is a familiar moisturiser that suddenly stings, tight waxy-looking skin, small flaky patches, and acne that gets worse instead of better. If your skin stings on a product you've used for months, stop all acids, retinoids, and vitamin C for two to four weeks; cleanse gently, use a ceramide moisturiser, wear mineral sunscreen. Most cases settle inside three weeks. If it hasn't calmed in a month, see a dermatologist.

Some skin should stop entirely right now. No exfoliation during an active rosacea or eczema flare, on broken or sunburned skin, or in the week after waxing or laser. On isotretinoin, dial home use to almost nothing. In pregnancy, low-percentage glycolic and lactic are low-risk; salicylic is fine on small areas but not at peel strength 4. On darker skin, the main risk is lingering dark patches after any irritation, so stay at the low end, favour mandelic or gluconolactone, and treat sunscreen as mandatory 8.

The tingle does not mean it's working. A well-formulated acid at the right pH usually doesn't sting; stinging means the barrier is already compromised. "Use daily for best results" is a marketing line — the strongest studies used 25% glycolic closer to an in-office peel, and true daily use suits only a minority of oily skin. Read "daily" on the box as "probably twice a week." And physical scrubs aren't inherently damaging: soft round abrasives used lightly once a week are fine; jagged nut-shell grit dragged hard is the actual problem.

დაკავშირებული სახელმძღვანელოში (5)
Undermines
  • — Most 'my moisturiser stopped working' problems are over-exfoliation quietly stripping the barrier.
დაკავშირებული
  • — Harsh cleansing stacks on exfoliation to strip skin; match a mild cleanser to a conservative exfoliation cadence.
  • — Dry brushing counts toward your exfoliation budget; stacking it on acids is how skin gets over-stripped.
  • — Acids are one of the four active families — but cadence matters more than strength; almost never daily.
  • — Fresh-exfoliated skin burns faster — acids and scrubs strip the top layer, so daily SPF is non-negotiable if you exfoliate at all.
