Choosing Milk Ingredient for Milky Serum

For making a cloudy white, milky serum, you should use cosmetic-grade milk extracts or derivatives, not fresh milk.

Fresh milk is not suitable for cosmetic formulations because:

• It is highly perishable and can spoil quickly.
• It contains components that are prone to bacterial growth, leading to contamination and safety issues.
• It is difficult to stabilize and preserve in a serum base.

Cosmetic-grade milk ingredients, such as hydrolyzed milk protein, milk lipids, or other processed milk derivatives, are specifically prepared for use in skincare products. They are stable, safe, and provide beneficial properties while contributing to the desired texture and appearance.
