Boots Smooth Sensitive Wax Strips are pre-coated with a gentle, hypoallergenic wax formula enriched with chamomile and azulene to minimize irritation during and after hair removal. Each strip clings firmly to hair at the root, removing it cleanly and leaving skin silky smooth for up to four weeks. The soothing post-wax wipes included in the pack remove any residue and calm the skin immediately after use. Dermatologist-tested and ideal for those with reactive or delicate skin.
