About YOGURT
A dairy-derived fermentation product containing lactic acid, proteins, and lipids that conditions skin and supports the skin barrier through its naturally occurring nutrients.
Detailed Analysis
Yogurt is the fermented product of milk, typically by Lactobacillus bulgaricus and Streptococcus thermophilus, producing lactic acid, whey proteins, casein, milk fats, and B vitamins. Under EU regulation 1223/2009, dairy-derived ingredients are not restricted. Lactic acid (naturally present in yogurt) is itself regulated under Annex III with a maximum of 10% in ready-to-use cosmetics. The ingredient provides natural moisturization through milk fats and mild exfoliation through lactic acid, with a well-established safety profile for topical application.
