Regarding your inquiry about the toner formulation:

The staff has confirmed that the ingredients in your toner formula can be mixed together.

Mixing Instructions:
Gradually add each ingredient into the Witch Hazel (Alcohol Free) Plus Allantoin base. Stir or blend gently until everything is dissolved and well combined.

Important Note:
The staff advises that using DMAE at a 10% concentration may cause skin irritation, especially for those who have not used it before. It is recommended to start with a lower concentration, such as 5%, if you are new to this ingredient.
