Formulation Analysis

Your formula includes a good combination of active ingredients targeting moisturizing, anti-wrinkle, and whitening benefits:

• Moisturizers: Rose Water, Double Hyaluron Liquid, Aloe Vera Extract, WaterLock™, Repair Activator™. These help hydrate the skin and prevent moisture loss.
• Anti-wrinkle/Antioxidants: Pure-Adenosine™, Pure-EGCG™, Pure-Phloretin™, Perfect-C™, Repair Activator™, Shiso Extract, Pure-Naringin™. These ingredients work against signs of aging and protect the skin from free radical damage.
• Whitening: Perfect-C™, Pure-Naringin™, Pure-Phloretin™. These ingredients can help brighten skin tone.
• Soothing/Anti-inflammatory: Rose Water, Aloe Vera Extract, Shiso Extract, Pure-Naringin™, Pure-EGCG™, Pure-Phloretin™. These can help calm skin irritation.

The percentages of the active ingredients seem reasonable for a cosmetic product.

Procedure Analysis

Your procedure outlines the steps for mixing the ingredients. However, based on the ingredients and the use of Light Cream Maker™, this formulation is designed to create a light cream or lotion, not a typical low-viscosity serum. Serums are generally much thinner.

Regarding the steps:

1. Steps A, B, and C: Mixing the water-based ingredients and hydrating the Hyaluronic Acid is a standard approach for the aqueous phase.
2. Step D: Combining several active ingredients (Pure-Adenosine™, Pure-Naringin™, Pure-EGCG™, Pure-Phloretin™, Perfect-C™) together before adding them to the water phase (C).
3. Step E: Adding the mixture from D to C, then adding Repair Activator™, and finally adding Light Cream Maker™ to form the cream.

The main point to consider is the incorporation of Perfect-C™ (Ascorbyl Tetraisopalmitate). According to its description, Perfect-C™ is an oil-soluble Vitamin C derivative. While Light Cream Maker™ is an oil-in-water emulsifier that works without heat and can handle up to 20% oil, your procedure mixes the oil-soluble Perfect-C™ with several water-soluble or dispersible powders (Pure-Adenosine™, Pure-Naringin™, Pure-EGCG™, Pure-Phloretin™) in step D and then adds this mixture to the water phase (C) before adding the emulsifier (Light Cream Maker™).

This method might not properly emulsify or disperse the oil-soluble Perfect-C™ into the final cream structure. Oil-in-water emulsifiers like Light Cream Maker™ typically work best when the oil phase (containing oil-soluble ingredients) is gradually added to the water phase (containing water-soluble ingredients and the emulsifier) while stirring, or when the emulsifier is added to the oil phase before combining with the water phase, depending on the specific emulsifier instructions.

Additionally, the description for Light Cream Maker™ notes that ingredients containing electrolytes, such as Aloe Vera Extract, can soften the cream, and suggests adding such ingredients gradually at the end and potentially increasing the amount of Light Cream Maker™ if needed. Your procedure adds Aloe Vera Extract in step A, before the cream is formed.

Conclusion

The ingredients you have chosen are suitable for a product aiming for whitening, anti-wrinkle, and moisturizing effects. The formula will result in a light cream texture due to the inclusion of Light Cream Maker™.

However, the proposed procedure for incorporating the oil-soluble Perfect-C™ might not be the most effective method for ensuring its stability and even distribution throughout the cream. A more standard emulsification technique that properly incorporates the oil-soluble component with the emulsifier would likely yield a more stable and consistent product.

It is recommended to follow the specific usage instructions for Light Cream Maker™ and Perfect-C™ to ensure proper formulation, especially regarding the incorporation of oil-soluble ingredients and handling of electrolytes.
