How To Quickly Repair A Broken Skin Barrier

Dr. Shereene Idris, dermatologist, shows us what we can do at home:

Saving face

We say that, since of course the face, being some of the most sensitive skin on the human body and yet at the same time the most habitually exposed, it’s usually the site of such problems as a broken skin barrier.

First though, what actually is the skin barrier? It’s the outermost part of the epidermis (the stratum corneum) that protects against pollution, pathogens, and moisture loss; it’s made of skin cells (the “bricks”) and a lipid matrix (the “mortar”) of ceramides, cholesterol, and fatty acids, topped by an acid mantle that maintains a pH of about 5–5.5.

However, overuse of exfoliants, retinol, or random serums can strip the barrier, leading to redness, tightness, peeling, dryness, itching, burning, and breakouts.

Here’s Dr. Idris’s 5-step plan for fixing it:

1. Stop: stop all products, including sunscreen, moisturizers, and actives; only cleanse with a very gentle cleanser (and if you’re unsure, then just water); protect skin from the sun physically with hats etc instead of sunscreen until healed.
2. Soothe: use simple occlusives like Vaseline or other petroleum jelly to seal in moisture; if inflammation is strong, apply diaper rash cream (such as Triple Paste) with zinc oxide for extra anti-inflammatory protection.
3. Restart: after 2–3 days, introduce calming moisturizers containing glycerin, squalane, ceramides, or colloidal oatmeal; avoid hot water and rubbing your face—use lukewarm water and gently pat dry.
4. Reintroduce: after 1–2 weeks, patch test each of your usual products on a small area for several nights before adding it fully; mild tingling is acceptable, but persistent burning or redness means stop.
5. Rebuild: start with hydrating and soothing actives such as niacinamide (≤5%) or azelaic acid, then add gentle antioxidants like vitamin C derivatives (e.g. tetrahexyldecyl ascorbate) or coenzyme Q10; later, slowly reintroduce retinol and exfoliating acids (if you use them) on alternating nights, increasing frequency gradually.

If in doubt, then “less is more” is the principle to go by when it comes to skincare products:
