5 Mistakes That Might Be Ruining Your Skin Barrier
The barrier is the outermost layer of your skin — cells held together by lipids, keeping water in and irritants out. When it is working you do not think about it. When it is not, everything you apply seems to sting.
Almost all barrier damage is self-inflicted, and almost all of it comes from the same five habits.
Over-Cleansing and Over-Exfoliating
Skin that squeaks after washing has been stripped, not cleaned. A cleanser should leave the face comfortable enough that you could walk away without applying anything.
Acids and scrubs compound the problem. More than two or three exfoliating nights a week removes the barrier faster than it can rebuild, and the flaking that follows is often mistaken for a sign that more exfoliation is needed.
Stacking Actives and Chasing Reactions
A vitamin C serum, an acid toner and a retinoid in the same routine is three demands on skin that can meet about one. Tingling is not evidence that a product is working; it is usually evidence that the barrier is thinner than it should be.
- Washing in water hot enough to feel good on cold mornings.
- Using a new active every night to “push through” an adjustment period.
- Skipping moisturiser because skin already feels oily.
How to Repair It
Stop everything except a gentle cleanser, a ceramide moisturiser and sunscreen. Two weeks of that is usually enough for skin to settle, and there is no faster route — a barrier rebuilds at the pace it rebuilds.
Reintroduce one active at a time afterwards, at a lower frequency than before. The routine you return to should be smaller than the one that caused the problem.
