I have reactive skin—how should I check whether this peptide mask is suitable before putting it on my face?

The product description advises patch testing first if your skin is sensitive. A practical approach is to apply a small amount of the mask’s serum to a clean area such as the inner forearm or behind the ear, then wait 24 hours without washing the spot. If no redness, itching, or discomfort develops, you can try the full mask on the face for the recommended 20–30 minutes.

Even if the test is clear, avoid applying the sheet to irritated, broken, or damaged skin, as the formula is intended only for normal cosmetic care. During use, if you notice stinging, redness, or any discomfort, remove the mask immediately and rinse the area with water, then stop using the product. The mask is formulated especially for dry and normal skin types seeking a moisture boost, but reactive users should introduce it gradually—perhaps once a week—rather than several times in a short period.

Consult a dermatology specialist before use if you have a chronic skin condition, are pregnant, breastfeeding, or are using prescription topical medication, to ensure the routine is appropriate for your situation.
