Mixing Alpha Arbutin and Safe B3 for Sensitive Skin

Yes, you can mix Alpha Arbutin powder and Safe B3 (Niacinamide) powder with distilled water to create a solution that can be used as a "water essence" (น้ำตบ).

Here are some general guidelines:

• Alpha Arbutin: Typically used at 0.2% to 2%. For sensitive skin, start at the lower end (e.g., 0.2% to 1%).
• Safe B3 (Niacinamide): Typically used at 2% to 5%. While Niacinamide can be beneficial for sensitive skin, concentrations above 5% might cause flushing or irritation in some individuals. Start with 2-4% if you have sensitive skin.
• Mixing: Weigh the desired amount of powder(s) and dissolve them completely in the calculated amount of distilled water to reach the target percentage. Ensure the powder is fully dissolved before use.

Suitability for Sensitive Skin:

• Both Alpha Arbutin and Niacinamide are generally well-tolerated, and Niacinamide is often recommended for sensitive skin due to its barrier-strengthening properties.
• However, any active ingredient can potentially cause irritation, especially at higher concentrations.
• Recommendation: Start with lower concentrations of both ingredients. Always perform a patch test on a small area of skin before applying the mixture to your face.
• A simple water solution lacks the buffering agents, humectants, or soothing ingredients often included in commercial products formulated specifically for sensitive skin. If you find the simple solution irritating, you might consider adding a small amount of a gentle humectant like glycerin or using a different base.
