Too many actives: the most common cause of a damaged skin barrier

The most common route to damaged skin right now is not neglect. It is enthusiasm — a routine assembled from six different recommendations, each sensible on its own, layered onto one face.

What the barrier is, and how it breaks

The outermost layer of skin is a lipid barrier that holds water in and keeps irritants out. It is remarkably tough, and it is worn down by repetition — a little irritation daily, from several directions, is far more damaging than one strong treatment occasionally.

How to recognise a compromised barrier

• Products that never stung now sting, especially around the nose.
• Skin is flaky and oily at the same time.
• A persistent, low-level redness that does not settle.
• Spots healing slower than they used to.
• The feeling that "everything irritates my skin now" — which is the barrier reporting, not your skin type changing.

The combinations that cause it

Layering multiple exfoliating acids. Adding a retinoid on top of an acid routine. Physical scrubs on skin already being chemically exfoliated. And — the herbal version of the same mistake — lemon juice, baking soda or neat essential oils stacked onto a routine that was already doing enough.

What to do about it

Strip back to three steps for two to four weeks: a gentle cleanser, a moisturiser, and sun protection. Nothing exfoliating, nothing "brightening", nothing new. It is dull, and it works.

Then reintroduce one thing and hold everything else constant for two weeks. If something reacts, you will know exactly what.

The rule worth keeping permanently

One new product at a time, two weeks apart. It is slower, and it is the only way to learn anything about your own skin. A routine assembled in one weekend teaches you nothing when it goes wrong.

If you want to start from a settled base, the Pureglow Face Wash is the gentler of our two cleansers and a reasonable place to begin.

And when to stop reading articles

If skin is broken, weeping, or persistently painful, that is not a barrier issue to manage with product choices. See a dermatologist.
