Before treatment:
Grow out your hair so it can be seen and easily grasped with tweezers
Gently exfoliate the area to be treated (a scrub with a washcloth is fine)
Drink plenty of water to hydrate the skin and hair
No caffeine directly before your appointment (caffeine can increase dehydration and cause increased sensitivity)
No retinol products on the area to be treated for at least a week before treatment (retinol can thin the skin and make it more sensitive and reactive to treatment)
After treatment:
Stay out of the sun for at least 24-48 hours
Use sunscreen (preferably mineral sunscreen)
No deodorant, make-up, or rubbing alcohol for 24-48 hours on the treated area
Refrain from going to the gym or using saunas for 24 hours after treatment. You want to keep your skin cool and free from sweat and friction so as not to irritate it.
Don't touch the area.
Keep skin clean using mild soap
Keep skin moisturized with perfume-free and mild lotions
No exfoliation until skin has settled
