gentle, low-maintenence exfoliator.
I bought the mini version of this brush and I love it for long-term treatment of pretty much any skin condition. It's a great exfoliator on my sensitive, blemish-prone skin, and I also think it improves brightness and helps my cleanse penetrate more effectively to clear my pores. I only use it probably 3-4 times a week. Other perks are that it SO rarely needs to be charged and super easy to travel with. I use it with a tea tree oil cleanser, as any soaps that are hyper-exfoliating are too much with the foreo.
