A good toner essentially delivers hydration to the skin after cleansing and helps remove dead skin cells / built up left after cleansing. It also prepares the skin for the serums to follow and helps in improving active delivery. Minimalist PHA 3% + Biotic toner is formulated to provide three primary benefits: 1. Gentle exfoliation: PHAs are next generation AHAs. Because of its larger molecule size compared to Glycolic acid (molecular weight 178 vs. 76 for Glycolic acid), it penetrates the skin slowly, hence offering gentle exfoliation without causing any skin irritation 2. Hydration: Formulated with an optimum blend of several hydrating ingredients to give your skin a boost of much needed hydration after cleansing. This formula contains super hydrators like Polyglutamic Acid, Panthenol (Vitamin B5), Xylitylglucoside, Anhydroxylitol, Xylitol, Saccharide Isomerate and Amino acids like Lysine, Histidine and Arginine. Combined, these ingredients restore the water skin loses during cleansing 3. Balance skin microbiome: Ecosystem of our skin is a complex environment and it has a diverse microbiota community. Probiotics are the good bacteria that naturally occurs in our body & on our skin and essentially maintains overall skin health. Prebiotics on other hand are what these good bacteria feed on. Prebiotics has been shown to selectively increase the activity and growth of beneficial skin microbiota. On the other hand, topical applications of probiotics directly effects the skin by enhancing its natural defence barriers. This product uses both forms of biotic to restore skin’s natural health and beauty.
