Using Milk Components in Cosmetic Formulations

Based on the discussion, fresh milk is generally not used in cosmetic formulations like creams. This is because fresh ingredients have a short shelf life and can easily be contaminated with microbes, which would cause the cosmetic product to spoil quickly.

Instead of fresh milk, cosmetic formulations use specific components or extracts derived from milk that are stable and suitable for long-term storage. Examples of such ingredients mentioned are:

• Lactic Acid (AHA): A type of Alpha Hydroxy Acid found in milk, known for its exfoliating properties.
• Hydrolyzed Milk (Casein) Protein: A protein derived from milk, often used for its skin conditioning benefits.

These ingredients allow cosmetic products to benefit from certain properties of milk components while maintaining stability and safety over time.
