Clean & Clear Persa-Gel 10

Experts recommend Clean & Clear Persa-Gel 10 for those with stubborn acne that resists other forms of treatment. It may be too strong for some, especially those with sensitive skin. Persa-Gel contains 10 percent benzoyl peroxide, the strongest dosage available in an over-the-counter treatment. Reviewers say it is very drying and often causes irritation, but most say the speedy results are worth it, and that it's useful as a spot treatment. Several users say Persa-Gel clears up acne in as little as one to three days. Experts recommend starting with a lower dosage of benzoyl peroxide, such as that found in Proactiv Solution 3-Step System (*Est. $20). Some reviewers say it is best used by those that suffer from occasional blemishes.
