How to use a brow dermaroller safely: step by step

Before you start

Clean, dry skin and a clean roller. Wipe the roller with alcohol before and after every single use, and let it dry. Never share it.

The four passes

Hold the skin taut with one finger. Roll lightly across the brow four times in each direction: across, up, down and diagonal. You are looking for a light tingle, not redness that lasts.

Then the serum

One stroke of serum along each brow straight after rolling. The roller has prepared the skin, so the serum gets where it needs to go.

The four rules

Up to three times a week, never more. Never on broken, irritated or acne prone skin. Replace the roller every three months. Stop if anything stings and speak to a pharmacist.
