Moderate caution

Sodium lauryl sulfate in skincare

A strong cleanser that can be drying or irritating for some skin types.

What to do about it

Prefer gentler surfactants if your skin feels tight after cleansing.

This one matters more in leave-on products — a serum or moisturiser that stays on your skin — than in a cleanser you rinse off within a minute. Skinvio weighs it less heavily for rinse-off formulas for that reason.
