Review title is Good Purchase [SEP] I was skeptical about this cleansing brush because it didn’t have the shape that could get into crevices. I’m glad I got over it. I’ve been using this and an older model I bought years ago and this one wins hands down. I don’t really have acne. My issues are t-zone congestion and my skin’s texture isn’t smooth. I’m in my mid 30s so I’m trying to get on the anti-aging boat lol. I really like that this has a heat feature. However, It takes about 1 minute 30<br />seconds to heat up so I’ll let it run and do something else. Wen it shuts off then I turn it on again and actually use it. Also the heat is mild. The device makes my skin super smooth and is gentle on the skin. I have combo/normal skin and I can’t stop touching my face. I wake up the next morning and my skin is still smooth. I started using it once a day, then twice a day but switched to once every three days on the lowest setting. My skin is still smooth so I don’t want to overdo it. You will see redness but it goes away fairly quickly. I wet my face, I wet the device and add my cleanser directly it. You can use less cleanser because the device distributes it nicely. This seems to work best with a cream cleanser. It stays on for 2 minutes but 1 minute should suffice. It doesn’t have a beep to let you know when to switch sections. The last setting that dries the device is a nice touch. I only get water on the bristles so I can’t speak on it being waterproof.  I’m thinking of purchasing another one for when the current one needs replacing. This device either has a 1 year warranty which is wonderful. I strongly recommend you give this a try.
