Hello, this is not normal. Please inform other components in the formula. How to mix EGF into the formula is the best. The complete product is obtained, add EGF to the formula, blend at high speed. but takes the shortest time Do not spin for a long time

Hello, please modify as follows: 1. Allantoin is insoluble in more than 0.5% of water. In this case, 83% of water is dissolved Allantoin about 0.4%, downgrade Allantoin to 0.35%. 2. Try changing สารกันเสีย from Phenoxyethanol which can cause a protein denature to Mild Preserved Eco 1% instead 3. EGF to the formula. in the last step If you don't use a blender To add and stir quickly and vigorously for a short time, do not stir too long.
