If you’re reading this before making the purchase, make sure you choose an epilator with a higher number of tweezers. More tweezers mean less pain. This way, you’ll minimize skin irritation as well as the pain of your hairs being plucked from the roots.
If you have a waterproof epilator, you can hop into the shower and carry it with you. When you take a hot shower, your hair becomes softer and the pores open up making epilation less painful.
It also eliminates the hassle of cleaning because you can do it right there. Most epilators are compact enough to be carried while you travel, so you can always epilate pain-free as long as you have access to some warm water for showering.
