Very few cosmetics are entirely free of preservatives; this is because all cosmetic products that contain water are prone to bacterial growth. Traditional cosmetic preservatives use chemicals to inhibit bacterial growth. But these chemicals are harmful to both our skin and our health, so various international health organizations attempt to regulate the use of these chemicals. DrLOUIE products DO NOT USE any chemical preservatives. Then how are the products safe from bacterial activities? Simple. Through self-preservation system. DrLOUIE’s innovative self-preserving formula adjusts water activity and uses the synergy of the ingredients to inhibit microbial growth. So our products can be free of harmful chemical products while ingredients are still fresh and active. Dr. Louie, the developer of the DrLOUIE cosmetic line, is an expert on self-preservation system and has been working on perfecting a unique self-preservation system for more than 30 years, resulting in 4 patents related to self-preservation formula.
