• B. Vegetables
• C. Milk
• D. Grains

Answer: (C)

Lactic acid, known for its alpha hydroxy acid (AHA) properties, is primarily derived from milk. This substance is produced through the fermentation process of lactose, which is the sugar found in milk. Lactic acid has hydrating and exfoliating properties, making it a popular ingredient in skincare products aimed at improving skin tone and texture. Its ability to enhance the skin's natural moisture retention while promoting cell turnover makes it particularly beneficial for esthetic procedures. While fruits, vegetables, and grains can contain various acids, they are not the direct source of lactic acid. Instead, they tend to be associated with other types of acids, such as citric acid from citrus fruits and malic acid from apples. Therefore, understanding the origin of lactic acid is crucial for estheticians and skincare professionals to effectively utilize its benefits in treatment formulations and recommendations.
