Adding Active Ingredients to Ready-Made Peel-Off Masks

You are looking to add active ingredients to a ready-made peel-off mask base. The suitability of active ingredients depends on the type of ready-made mask base you are using and the properties of the active ingredient itself. Generally, peel-off mask bases are water-based systems, so water-soluble active ingredients that are compatible with the polymers used in the mask base are usually suitable.

Here are types of active ingredients and examples commonly used in peel-off masks:

• Hydrating Agents: Help increase skin moisture, making the skin look plump.
  • Examples: Hyaluronic Acid, Glycerin, Panthenol (Vitamin B5)
• Soothing Agents: Help reduce irritation and soothe the skin.
  • Examples: Aloe Vera Extract, Chamomile Extract, Allantoin
• Brightening Agents: Help reduce dark spots and even out skin tone.
  • Examples: Vitamin C Derivatives (e.g., Sodium Ascorbyl Phosphate), Niacinamide (Vitamin B3) - compatibility with the base should be tested.
• Antioxidants: Help protect the skin from damage caused by free radicals.
  • Examples: Vitamin E, Ferulic Acid, various plant extracts such as Diosmetin (a Flavonoid with antioxidant properties).

Important Considerations:

1. Compatibility: Some active ingredients may react with components in the mask base, altering the mask's texture (e.g., thickening, thinning, separation) or reducing the active's effectiveness. It is essential to test with the specific mask base you plan to use in small quantities first.
2. Stability: Some active ingredients are not stable in water-based formulas or are sensitive to light and heat. You should check the stability information and the correct mixing method.
3. pH Level: Some active ingredients work best within a specific pH range. Adding active ingredients may affect the pH of the mask base and might require pH adjustment, which could impact the mask's peeling properties.
4. Usage Concentration: Active ingredients should be used at the recommended concentration according to the manufacturer's data. Using too much may not increase effectiveness but could cause irritation or negatively affect the mask's texture.

In summary, you can add water-soluble active ingredients that are compatible with the peel-off mask base, focusing on ingredients that provide hydration, soothing, or brightening benefits. Most importantly, you must test for compatibility and stability before actual production.
