Review (5/5): Overall pleased with the product and its functionality.
I felt like it worked pretty well. Noticed that it cleaned significantly. I got a facial with extraction last month and my esthetician back home recommended using one of these once a month if I didn't want to pay for a facial with extraction every month.
I didn't notice if the manual recommended how often it should be used, but I assume not too often since it can really affect your skin. Parts of my face were affected worse than others, but the redness went down significantly overnight. When I went to get my facial done, the redness was pretty evident on my face for about 4-5 days.
