Skincare treats repair and preservation as two versions of the same thing. They are not. Barrier repair is a reactive process — initiated when elevated TEWL signals that the lamellar lipid matrix has been compromised....

Most face washes are built around anionic surfactants. They produce foam, cut through oil, and leave skin feeling unmistakably clean. They are also, according to decades of barrier research, the most consistent source of daily...

TEWL — transepidermal water loss — is the measurement researchers and dermatologists use to assess whether a skin barrier is intact or compromised. This article explains what TEWL is, why some degree of it is...

A cleanser that caused no problems at 28 can be quietly destabilising the same skin at 45. Not because the formula changed. Because the skin it is landing on has. The barrier's capacity to recover...

Moisturising every day and still waking up to dry, tight skin is one of the most common skincare frustrations — and one of the most systematically misunderstood. The moisturiser is not failing. The problem is...
