My skin reacts easily — how can I tell if these strips are safe for me before doing a full area?

Because the strips contain activated charcoal and black caviar extract alongside the wax base, treat them as an active cosmetic product. Cut a small piece (about 1 cm²) from a strip and apply it to a discreet area — such as the inner forearm or just behind the ear — following the same warm-press-pull method. Wait 24 hours. If you see persistent redness, itching, swelling, or tiny blisters, do not use the product on your face or bikini line. Even without a reaction, avoid waxing if the skin is currently irritated, has micro-cuts, active breakouts, sunburn, or if you have used strong exfoliants (AHAs, BHAs, retinoids, physical scrubs) in the past 48 hours. These ingredients thin the stratum corneum and make lifting more likely. If you are on topical prescription treatments (e.g., tretinoin, isotretinoin), consult your dermatologist before waxing any area. Hormonal changes (menstrual cycle, pregnancy) can also heighten sensitivity, so consider timing your session for when your skin is typically calmest.
