Melasma Reduction Serum Gel Formulation: Mixing Reservoir Tech and Pro Polymer

Subject: Review of Melasma Reduction Serum Gel Formula

Thank you for sharing your melasma reduction serum gel formula.

The combination of active ingredients you have chosen, including Tranexamic Acid, Alpha Arbutin, Niacinamide (Vitamin B3), and N-Acetyl Glucosamine (GlucoBright), is a good approach for targeting melasma and hyperpigmentation through multiple mechanisms. Willow Bark Extract, containing natural salicylic acid, can also contribute to skin renewal and potentially improve the efficacy of other actives. The concentrations of the key actives appear to be within effective ranges commonly used in cosmetic formulations.

Regarding the mixing procedure, the staff's advice is correct. Reservoir Tech should be added after Pro Polymer has been fully dispersed and has created the gel structure. This is because Reservoir Tech is not easily soluble in water alone and requires the gel matrix formed by Pro Polymer to help incorporate it smoothly into the formula.

Additional recommendations:

• Check pH: The efficacy and stability of some ingredients (like Alpha Arbutin and potentially the salicylic acid from Willow Bark Extract) can be pH-dependent. Aim for a pH that is suitable for skin application (typically between 4.5 and 6.0) and also optimal for the stability and activity of your chosen ingredients.
• Stability: With multiple active ingredients, monitor the formula for any changes in color, odor, or texture over time to ensure stability.
• Patch Test: Always perform a patch test on a small area of skin before applying the product to the entire face to check for any irritation or allergic reactions.

Overall, this looks like a promising formulation for targeting melasma.
