no- your hair doesn't come back thicker or darker, l've been doing this at least once a month for 8 or 9 years. It's just peach fuzz. But getting rid of it helps exfoliate the skin and makes your makeup look amazing. I'm obsessed with this spray , it helps you find every hair and keeps your skin moisturized. For 20 years old and up only!! Please preteens and teens, don't do this. It could be dangerous for you to use the razor and you really don't need it! skincare skincareroutine LTKOver40 LTKSummerEdit LTKFindsUnder50
