How to patch test new skincare

A simple two-day check before you put something new on your face.

Five minutes now can save a week of irritated skin.

How

Apply a small amount to clean skin on your inner arm or just behind the ear.
Leave it on and don't wash the area for 24 hours, ideally 48.
Check for redness, itching, burning or swelling.
No reaction? Try it on a small area of your face before using it everywhere.

Good to know

A patch test can't predict everything, especially with exfoliating acids, which can tingle at first. If you have a known allergy, check the full ingredient list (INCI) on the product page before buying. If you have a skin condition, ask a dermatologist.
