Does Artistry Signature Select™ Personalized Serum Hydration Amplifier address the Balance Skin Nutritional Requirement and help balance skin’s microbiome?Yes, the Hydration (H) Amplifier can be considered to address the Balance requirement. In fact, it works in a beautifully complementary way to the Artistry Skin Nutrition™ toners — both promote a balanced microbiome, but they work in different ways. The H Amplifier encourages defense mechanisms within the skin and the Artistry Skin Nutrition™ toners reduce biofilm formation. We’ve learned that keeping the microbiome in balance (and preventing biofilms) is one of the key Skin Nutritional Requirements for visibly healthy skin.
