Adding Tranexamic Acid 4% to Eye Gel Formulation
Question
I have a gel formulation with the following ingredients:
- Double Hyaluronic (Hyaluron) Gel
- Whitening: Glucosamine (N-acetyl-D) 4%
- Whitening: Nanowhite 5%
- Moisturizing: Bio-Yeast Essence 1%
- Anti-Aging/Anti-Acne: Vitamin B3 (Niacinamide) 3%
- Anti-Aging: Gotu Kola (Centella Asiatica) Extract 5%
- Anti-Aging: Argireline 10%
- Anti-Aging: REGU®-AGE สำหรับรอบดวงตา 5%
- Preservative: Phenoxyethanol
If this gel is intended for use around the eyes, can I add Tranexamic Acid 4% to the formulation?
Answer
Adding Tranexamic Acid to Your Eye Gel
Based on the information available for Tranexamic Acid (Trans-White™), it is not recommended to use this ingredient around the eyes or lips.
Additionally, the regulatory limit for Tranexamic Acid in cosmetics in Thailand and ASEAN countries is no more than 3% for skin brightening purposes. Using 4% would exceed this limit for cosmetic registration. If a formula contains more than 5%, it must be registered as a medicine for treating melasma.
Therefore, adding 4% Tranexamic Acid to your gel formulation is not advisable, especially for use in the eye area, due to both safety recommendations and regulatory restrictions.
