Adding DMAE to Your Toner Base

To add liquid DMAE to your 120g Witch Hazel Alcohol-Free Toner base containing 5% Vitamin B5 and 5% Matrixyl 3000, you can aim for a final DMAE concentration of around 3%, which is a commonly recommended usage rate.

Here's how to do it:

1. Calculate the amount: For a 120g base, adding approximately 3.7 grams of liquid DMAE will result in a final concentration of about 3%.
2. Mixing: Ensure your toner base is at room temperature (below 40°C). Carefully measure about 3.7 grams of liquid DMAE and add it to the 120g toner base. Gently stir or swirl the mixture until the DMAE is completely and evenly mixed in.

Important Considerations:

• The recommended usage rate for DMAE is typically 1-10%. While up to 10% can be used, concentrations above 5% may cause skin irritation or a sticky feeling. Starting at 3% is generally recommended, especially for sensitive skin.
• DMAE is known to work well with Vitamin B5, which is already present in your base.
