Using AHA in Skin Cream Formulations

Yes, AHA can be used in skin cream formulations. Common types of AHA used in skincare include Glycolic Acid and Lactic Acid, which help exfoliate skin cells, leading to smoother and brighter skin.

However, there are important considerations and regulations when using AHA in skin creams to ensure safety and effectiveness:

• Concentration: For products used by general consumers, the concentration of AHA should not exceed 10% (some types like Glycolic Acid recommend not exceeding 5%). Higher concentrations (up to 30%) should only be used under the supervision of a dermatologist.
• pH Level: Formulas containing AHA should have a pH not exceeding 4.0 for optimal effectiveness. According to FDA requirements for general consumer products, the pH must not be lower than 3.5.
• Mixing: Most AHAs can be mixed into the water phase of a formulation. Avoid temperatures above 60°C as this can degrade AHA.
• Sun Protection: Using products with AHA makes the skin more sensitive to sunlight. It is crucial to always use adequate SPF sun protection concurrently and avoid direct sun exposure.

AHA products that can be used in skin cream formulations include:

• Glycopure™ (Glycolic Acid (AHA) 100% Powder)
• Lactic Acid (AHA) Neutralized (pH adjusted type)
• Lactic Acid (AHA) 90% (ordinary grade - smells)
• Lactic Acid (AHA) 90% Deodorized (odorless)

The choice of which type to use depends on the desired properties in the formula. For example, Glycolic Acid has a smaller molecule and penetrates better than Lactic Acid, while Lactic Acid Neutralized is less irritating than other types.
