A zinc sulphate spray to purify and soothe blemish-prone, irritated skin
La Roche-Posay Serozinc is a zinc sulphate solution for oily, blemish-prone skin, and skin irritated after shaving or sun exposure. A cult La Roche-Posay staple, it is simply a solution of zinc sulphate in thermal spring water, sprayed on to help purify oily areas, calm minor irritations, and refresh the face throughout the day.
The texture
A clear, watery spray that dries down fast, leaving a slightly mattified, refreshed feel with no residue.
Who it suits
- Oily or blemish-prone skin wanting a purifying toner step
- Skin irritated after shaving or a day in the sun
- A quick midday refresh over make-up
- Anyone who wants a very simple, fragrance-free toning spray
Worth knowing before you buy: It contains no active acne treatment ingredient beyond zinc sulphate itself, so it works best paired with a dedicated blemish treatment rather than alone.
