I have hypersensitive, rosacea-prone skin. I've been using the complete ZZ system for about a month, and my skin looks better than it ever has. I don't have any blemishes (if only you knew how mind-blowing that is for me--I've had breakouts since I was 7 years old!), there's much less redness, and best of all my skin isn't constantly itchy and burning. Love it!
