This kit is nice because it comes with a cleanser, toner, and treatment lotion. It is extremely comparable to Proactiv in many ways but this is better because you can buy it from the store and it costs a little less. I found that this kit had helped me some with my acne. The only problem I seemed to have had was that it was a little too drying, which is common for many Benzoyl Peroxide products. I wish this kit would have included a really good moisturizing lotion to combat the dryness some. Overall I am satisfied with my purchase and would most likely purchase this product again. Effectiveness It cleared up my acne some but not entirely. I still got more than five breakouts every other day. Ease of Application The application is easy. With the cleanser you just distribute it onto your hand and massage your face for a minute. The toner you can apply with a cotton ball and the treatment lotion,you just take a small amount and apply to problem areas.I recommend not over doing it with the treatment lotion because it will dry your skin out. Convenience This product is really convenient for me to buy because you can either go to the store or purchase it online. Side Effects Some side effects are dryness and itchy skin. I recommend keeping this away from sensitive skin like around your eye area because you could have an allergic reaction and have your face swell up. Mostly the side effects are common ones and nothing major. Immediacy It didn't work immediately. It took a couple days to see a difference.
