I love this acne treatment regimen! It keeps me blemish free and I never worry about breakouts! I would highly recommend this to anyone that has even the smallest amount of blemishes! I do not have severe acne, so I am not certain how it would help that type of condition, however it is wonderful for occasional blemishes and minor breakouts. Effectiveness I never have breakouts since I started using this acne treatment regimen. Ease of Application This is very easy to use! I use cotton balls to apply. The application is as easy as can be. Convenience I find it very easy to use. I keep a set in my bathroom that I use in the morning, and I keep a set a the gym that I use after every workout. It is very convenient to carry with you because the bottles are lightweight and portable. Side Effects I have not had any side effects. My skin is very clear without any redness or drying. Immediacy I used this for about two weeks before I saw a major improvement in my skin and complexion.
