We always advise you complete a patch test before using our products. To do this, please apply a small amount of the eyeliner on to the skin behind your ear to check there is no irritation. You should allow 24 hours to ensure no reaction occurs before using the eyeliner properly.
If any irritation occurs, please wash off immediately using a cotton pad doused in micellar water. Once removed, continue to wash with cold water to ensure all the product is removed.
If irritation continues, please seek medical attention.
