Sensitive skin is not a skin type. It's a skin condition, and in most cases, it's caused or worsened by the products people use trying to fix it.
True physiological sensitivity, where the skin produces an exaggerated response due to genetic factors or conditions like rosacea, affects a relatively small percentage of the population. What most people call sensitive skin is reactive skin, a skin barrier that has been disrupted and is now responding to ingredients it would previously have tolerated.
The pattern is always the same. Skin gets dry or breaks out. Person introduces more products to fix it. Some of those products contain fragrance, alcohol, or harsh surfactants. Barrier gets more compromised. Skin becomes more reactive. More products are introduced. The cycle continues until the person believes they simply have sensitive skin and always will.
The most common irritants in skincare that are marketed as beneficial are: synthetic fragrance (the number one cause of contact dermatitis in skincare), denatured alcohol (listed as Alcohol Denat, used in toners and serums to create a fast-drying finish), sodium lauryl sulphate (a surfactant used in cleansers that strips the lipid barrier), and essential oils (which are biologically active and frequently irritating even at low concentrations).
Ecru products contain none of these. The formulations are fragrance-free, alcohol-free, and built around ingredients chosen specifically because they support barrier function rather than compromise it. Panthenol in the Face Cream converts to pantothenic acid in the skin, which is essential for barrier lipid synthesis. Glycerin in the Cleanser maintains hydration through the cleansing process. Betaine in the Serum is an amino acid derivative that reduces sensitivity responses.
If your skin is reactive, the solution is almost always simplification. Fewer products. Better-formulated products. More time.
