Question
Can Natural Moisturizing Amino Acids, Hyaluronic Acid, and LHA be combined in a serum formulation? What are the considerations regarding their stability, especially concerning pH?
Answer
Based on the information, combining Natural Moisturizing Amino Acids, Hyaluronic Acid, and LHA in a serum is possible, but stability depends on the pH.
- These ingredients are generally stable at pH 4.0 and above.
- If using a high concentration of LHA, measure the final formula's pH.
- If the pH is below 4.0, adjust it upwards with a base.
- Note that raising the pH might slightly reduce the effectiveness of LHA.
