This may occur, but normally, skin irritation disappears quickly. Your skin gets used to epilating by regular use. To avoid skin irritations stretch your skin with your free hand while epilating.
To relax the skin, we advise you to apply a moisturizing cream (for the bikini zone) or a mild alcohol-free deodorant (for the armpits) immediately after or a few hours after epilation, depending on what is better for your skin.
When you epilate sensitive areas for the first time, skin irritation is not unusual, as the skin is very sensitive here. Therefore we advise you to epilate before going to bed, as skin irritation usually disappears overnight.
