Information about Ingredients from MySkinRecipes

Here is the information regarding your questions about the ingredients from MySkinRecipes:

1. Vitamin B3 (Niacinamide) Concentration

Vitamin B3 (Niacinamide) products like Safe-B3™ and Extreme-B3™ are sold as high-purity powders. This means the raw material itself is essentially 100% concentration. The concentration you use will depend on your specific formulation, typically ranging from 1% to 10%. Safe-B3™ and Extreme-B3™ are special grades that can be used up to 10% without causing flushing or irritation, unlike standard grades which may cause irritation at concentrations above 5%.

2. Vitamin C (L-Ascorbic Acid) Concentration and Mixing

L-Ascorbic Acid Vitamin C is also sold as a high-purity powder. The recommended usage rate in formulations is typically 3% to 15% (3% for general wrinkle reduction, 15% for skin whitening).

Regarding mixing with your existing lotion, L-Ascorbic Acid is not stable when dissolved in water and is prone to oxidation. It requires specific conditions for mixing, including maintaining a low pH (ideally between 2.0-4.0, but FDA requires at least 3.5 for leave-on products) and often requires chelating agents like Disodium EDTA to prevent degradation caused by metal ions. Therefore, simply mixing the powder into an existing lotion is not recommended and will likely result in the Vitamin C degrading quickly and losing its effectiveness. Proper formulation is needed.

3. Difference between Mica Powder and Bismuth Oxychloride, and Mixing in Cream

• Mica Powder: These are mineral powders used in makeup to add softness, lightness, and natural coverage. Depending on the particle size and coating, they can also provide a subtle shimmer or matte finish.
• Bismuth Oxychloride (MakeGlow™ Powder): This is a mineral powder that provides a smooth, lustrous texture and a high shine or "Dewy-Glow Effect". It is commonly used in mineral makeup. However, it may not be suitable for sensitive or oily skin as it can cause irritation or make the skin appear more oily.

Both are powders, and while Mica Powder descriptions mention blending into formulas, and there is a liquid form of Bismuth Oxychloride suitable for creams, simply mixing the powder forms directly into an existing cream is generally not recommended. Achieving proper dispersion and a stable, aesthetically pleasing product usually requires specific formulation techniques and equipment.
