K.U.
This sounds funny, but I use an electric toothbrush to exfoliate a few times a week and I love it. It's the generic brand from Walmart so it was under $5. I just make sure not to push too hard since the bristles aren't meant for the skin.
Something else I just started using every night and LOVE is 100% pure passion fruit oil. I ordered for around $7 from Natural Bliss' website. I noticed immediately how much smoother and glowy my skin became, my breakouts seriously stopped overnight and my skin is more even-toned and this is only 2 weeks into starting!
