Serum Formulation Review and Mixing Guide

Thank you for providing your serum formulation. This formula aims to provide moisturizing, brightening, fragrance, and UV protection benefits.

Let's review the ingredients and how to mix them:

Ingredient Review

• Water (67.00%): The base of your serum.
• Allantoin (0.50%): Helps reduce irritation and supports skin tissue regeneration. The concentration is within the recommended range and aligns with its solubility in water at room temperature.
• TreMoisture™ (Trehalose) (3.00%): A humectant that enhances skin hydration and helps strengthen the skin barrier. The concentration is within the recommended range.
• GlucoBright™ (Acetyl Glucosamine) (4.00%): Works for skin brightening, reducing dark spots, and boosting hyaluronic acid production for moisture. It pairs well with Niacinamide.
• Safe-B3™ (Vitamin B3, Niacinamide) (4.00%): Offers multiple benefits including reducing wrinkles, hyperpigmentation, improving moisture, strengthening the skin barrier, and controlling oiliness. The concentration is within the recommended range for this high-purity type.
• Light Cream Maker™ (0.50%): This acts as an emulsifier and thickener to create the serum texture. It works without heat and can handle the oil/dispersed phase components in your formula (Bisoctrizole, PMMA Booster, fragrances).
• Bisoctrizole (MBBT, e.q. Tinosorb M) (5.00%): A broad-spectrum UV filter protecting against UVB, UVA I, and UVA II.
• PMMA Booster (SPF/Color Booster) (5.00%): Functions as an SPF booster to help increase the sun protection value of the formula.
• Flora Fix™ (5.00%) and Miss Dior (5.00%): These provide the fragrance for the serum. Note that the total percentage of your formula is slightly over 100% (100.5%). You may need to slightly reduce the water percentage to reach exactly 100%.
• Mild Preserved Eco™ (Preservative-Free) (1.00%): A gentle, preservative-free option that also offers some moisturizing properties.

Suggested Mixing Method

Here is a possible method for mixing your serum:

1. In a beaker, combine the Water, Allantoin, TreMoisture™ (Trehalose), GlucoBright™ (Acetyl Glucosamine), and Safe-B3™ (Vitamin B3, Niacinamide). Stir until all powders are fully dissolved.
2. In a separate container, combine Bisoctrizole (MBBT, e.q. Tinosorb M), PMMA Booster (SPF/Color Booster), Flora Fix™, and Miss Dior fragrance. Add the Light Cream Maker™ to this mixture and stir to disperse.
3. Slowly add the mixture from step 2 into the water phase from step 1 while stirring continuously. Stir until a uniform serum consistency is achieved. Avoid high-speed mixing (above 2500 rpm).
4. Add the Mild Preserved Eco™ (Preservative-Free) and stir until fully incorporated.
5. Check the pH of the final product. For optimal performance of GlucoBright™ and Safe-B3™, the pH should ideally be between 4.0 and 7.0.

SPF 50 PA+++ Achievement

You asked if Bisoctrizole (MBBT, e.q. Tinosorb M) at 5% and PMMA Booster (SPF/Color Booster) at 5% will achieve SPF 50 PA+++.

Both Bisoctrizole and PMMA Booster are effective ingredients for UV protection and boosting SPF/PA values. The PMMA Booster description indicates that at a 5% concentration, it can significantly increase SPF (potentially doubling it or more) and PA. However, the actual SPF and PA level of a final product depends on the entire formulation, including the interaction of all ingredients and the manufacturing process.

To confirm that your specific serum formulation achieves SPF 50 PA+++, it is essential to perform laboratory testing (in-vivo or in-vitro) on the final product. Based on the ingredients and concentrations, achieving SPF 50 PA+++ is possible, but it cannot be guaranteed without testing.
