The Barrier: Why Skin Stings And Feels Tight

Bricks And Mortar

The standard description is the best one. The flattened dead cells at the surface of your skin are the bricks. Between them sits a lipid mixture — ceramides, cholesterol and fatty acids — and that is the mortar.

The mortar is what the barrier actually is. It keeps water inside you and keeps irritants, allergens and microbes outside. When it is intact, skin feels like nothing. When it is not, skin becomes a topic.

How To Tell Yours Is Struggling

• Tightness immediately after washing, before you apply anything.
• Stinging from products you used to tolerate perfectly well.
• Redness or patchiness that comes and goes without an obvious trigger.
• Flaking alongside oiliness, which confuses people constantly.
• Moisturiser that seems to disappear within an hour.

That last pair is worth pausing on. Skin that is oily and flaky at the same time is not confused. It is losing water through a damaged barrier and producing extra oil to compensate, which is a barrier problem wearing an oily disguise.

What Breaks It

How It Repairs

The good news is that the barrier repairs itself given the chance, usually over two to four weeks. The bad news is that the chance means stopping things, which is harder than starting them.

• Simplify to three products. Gentle cleanser, moisturiser, sunscreen. Nothing else for a fortnight.
• Stop every acid and retinoid temporarily. They can come back later, more slowly.
• Wash in warm water, not hot, and pat rather than rub.
• Look for ceramides, glycerin and panthenol on a moisturiser label. All three have real evidence behind them.
• Give it four weeks. One turnover cycle, again.

The Inside Half

The barrier is made of lipids, and lipids have to be manufactured by the cells underneath. Pantothenic Acid supports that manufacturing, which is why its topical form, panthenol, appears in so many barrier-repair moisturisers. Vitamin A regulates how skin cells mature as they rise, and immature cells make a poorer barrier.

None of that replaces the three-product routine above. It is the other half of the same job, working from underneath while the moisturiser works from on top. Gelagen is built around exactly that idea.
