I would like to know if this formulation is viable, if the ingredient concentrations are appropriate, and if there are any potential issues like irritation or texture problems. The expert response mentioned potential irritation from the active ingredients and the need to adjust the Pro Polymer amount.

Answer

Hello,

Regarding your formulation for treating melasma, freckles, and dark spots:

  • Tranexamic Acid and Azelaic Acid: The staff noted that using both Tranexamic Acid (5%) and Azelaic Acid (7%) together at these relatively high concentrations might cause skin irritation, depending on your skin's sensitivity. However, they confirmed that these ingredients can work together effectively.
  • Pro Polymer: Due to the presence of Azelaic Acid, which can weaken the gel structure, the staff recommended increasing the concentration of Pro Polymer. They suggested starting with 1.5% and adjusting as needed to achieve your desired gel consistency.
  • Other Ingredients and Steps: The staff confirmed that the other ingredients and the mixing steps you provided are correct.

In summary, the formula is generally viable, but be mindful of potential irritation from the high concentration of the active ingredients, and adjust the Pro Polymer to get the right texture.
