Probiotic-based products make for a better skin care regimen. Not only are these products natural, but do not contain harsh chemicals, are environment-friendly, and are made with a water-based solution that is safe to use in the long-term. The MONO skin care line is a safer option because it does not dry your skin or cause allergic reactions, like benzoyl peroxide or salicylic acid have been known to do. Instead, it continues working long after the solution has been applied to the skin, requiring only 2 to 4 applications a day. Like a bacterial shield, it creates a protective layer of probiotics on the skin. This helps to maintain the proper and healthy level of good bacteria.
