The Microfine Face Scrub and Face Buff Brush can be used at different frequency for the best effect. Here’s a breakdown of what each product can do: 1) The Face Buff Brush can be used with a daily face wash to gently get rid of grime and debris, and lift up hairs to prep your skin for a close shave. 2) The Microfine Face Scrub contains a physical exfoliant (actual microfine particles buff away dead skin cells), as well as natural exfoliation agents like Alpha and Beta Hydroxy Acid, so it’s a little tougher on clearing pores and removing dead cells than the brush. Although the Face Scrub is also made for sensitive skin, you might want to only use the Face Scrub twice a week to get a feel for how it affects your skin. Then, if you think your skin is ready, you can increase the amount of times you use it. 3) Exfoliation and cleansing are integral for oily, but sensitive skin, but you should take the time to find your own skin schedule that works for you. After all, everyone’s personal preferences are different.
