Not a sponge was developed and designed by me, plain & simple….I designed not a sponge because I was tired of using makeup sponges on my sensitive skin that caused terrible breakouts. No matter how much I tried to wash my makeup sponges they never got clean or disinfected. As a professional makeup artist I never used makeup sponges on my clients because I didn’t feel confident in them being sanitary plus to use a new one on each client would cost a fortune. I did some research and found tons of people had the same issues as me and decided to do something about it.
