I have sensitive skin — can I use this mask and what precautions should I take?

If your skin is sensitive or reactive, do a patch test before applying the mask to your whole face: apply a small amount behind the ear or on the inner forearm, leave for the recommended time, rinse, and wait 24 hours to check for redness, itching, or stinging. Do not use the mask on already irritated, broken, or sunburned skin, and keep it well away from the eye area — the peel-off action and active ingredients can be too aggressive for the delicate periorbital zone. The formula contains yogurt components (milk proteins), lactic acid (an AHA), a vitamin A derivative, and essential oils for fragrance; each of these can provoke sensitivity in some people. If you have a known milk allergy or intolerance, the milk proteins in the yogurt powder are a potential concern. After removal, rinse with lukewarm water and follow with a fragrance-free moisturiser to support barrier recovery. If any persistent irritation occurs, discontinue use and consult a dermatologist.
