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 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 minute 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 minutes but 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 year warranty which is wonderful i strongly recommend you give this a try
