Lactobacillus/Pear Juice Ferment Filtrate
The details
This ingredient is exactly what it sounds like: pear juice fermented with the Lactobacillus bacteria (the bacteria is filtered out of the final product). The main thing that comes out of this process is lactic acid , an AHA. Lactic acid is one of the more well-studied AHAs in skincare: Fermentation also adds some bonus phenolic compounds with antioxidant activity. The only catch with this ingredient is that it is difficult to tell how much lactic acid is in any given product. Ferment filtrates don't come with standardized acid concentration like a 5% lactic acid serum would; this just means the actual exfoliating effect will vary depending on the formula's overall percentage and pH. Remember that AHAs make your skin more sun-sensitive, so be sure to wear sunscreen.
