Serum Formulation Advice

Thank you for your interest in our ingredients and for sharing your proposed serum formula. It's a good selection of ingredients targeting multiple skin concerns like wrinkles, dark spots, and texture.

Here are the answers to your questions:

1. Recommended Serum Base

Yes, we have ready-made serum bases that can simplify the formulation process and help achieve the desired texture. Based on your goal for a non-sticky, fast-absorbing serum, you might consider:

• Silky Serum Base (Face/Eye): Provides a smooth, non-greasy feel.
• Silky Serum Base Plus (Face/Eye, Oil): If you plan to include oil-soluble ingredients or want a slightly richer feel that is still non-greasy.
• Hyaluronic Acid Gel Base: A simple gel base that provides hydration.

Using a ready-made base can help ensure a pleasant texture similar to commercial serums.

2. Formula Suitability and Recommendations

Your selection of active ingredients is excellent for addressing wrinkles, roughness, dark spots, and promoting radiance. The combination of Niacinamide and Acetyl Glucosamine is particularly effective for brightening and improving skin tone.

Here are a few points to consider and potential adjustments:

• Soy Extract (Isoflaqua™): Your proposed concentration of 5% is higher than the recommended usage rate of 0.1-1.0% for Isoflaqua™. We recommend reducing the concentration to within the suggested range (e.g., 1%) to ensure efficacy and avoid potential issues.
• Vitamin B5 (D-Panthenol Care): While 5% is within the maximum usage rate, it can sometimes contribute to a slightly sticky feel in the final product, as noted in the product description. If you prioritize a completely non-sticky texture, you might consider reducing the concentration slightly (e.g., to 3%) or ensuring your chosen serum base is formulated to minimize tackiness.
• The concentrations of Safe-B3, GlucoBright, Centella Asiatica Extract (Madecassoside 90%), Alpha Bisabolol, and Liquid Azelaic are within or close to the recommended ranges and are suitable for your goals.

Overall, the formula is well-designed, and adjusting the Soy Extract concentration is the primary recommendation.

3. Mixing Steps

Assuming you are using a ready-made serum base, the mixing process is generally straightforward:

1. Add the water-soluble powder ingredients (Safe-B3, GlucoBright, Isoflaqua) and liquid ingredients (D-Panthenol Care) to your chosen serum base. Mix thoroughly until fully dissolved and homogenous. Gentle warming might be needed depending on the base, but avoid prolonged high heat.
2. Once the mixture has cooled to below 40°C, add the heat-sensitive ingredients (Centella Asiatica Extract, Liquid Azelaic). Mix well.
3. Add Alpha Bisabolol. Since it is oil-soluble, ensure it is properly dispersed or solubilized in the base. Mix until clear or evenly dispersed.
4. Check the pH of the final serum and adjust if necessary to a range compatible with all ingredients (ideally between pH 5.5-6.5).
5. If your serum base does not contain a preservative, add a suitable broad-spectrum preservative at the recommended usage rate.

Always ensure each ingredient is fully incorporated before adding the next.
