DIY Facial Treatment Mask Formulation

This formulation aims to replicate the key components of the SK-II Facial Treatment Mask based on the provided ingredient list and staff suggestions.

Ingredients:

• Galactomyces Ferment Filtrate (Pitera): 80-90% (Use either Galactomyces Ferment Filtrate (aka Pitera) or Galactomyces Ferment Filtrate (Glycol Free, Glycerin Free, Preservative Free))
• Water: Remaining percentage to reach 100% total liquid phase
• Butylene Glycol: 10%
• Xanthan Gum: 1% (Use Xanthan Gum (clear gel type, smooth texture))
• Disodium EDTA: 0.1%
• Preservative System: 0.2-1% (e.g., Sodium Salicylate + co-preservative)

Formulation Steps:

1. In your main beaker, combine the Water and Disodium EDTA. Stir until the Disodium EDTA is fully dissolved.
2. Slowly add the Xanthan Gum to the water phase while stirring vigorously or using a high-speed mixer to prevent clumping. Continue mixing until a clear, smooth gel is formed.
3. In a separate container, mix the Galactomyces Ferment Filtrate product with the Butylene Glycol and your chosen preservative system (e.g., Sodium Salicylate and a co-preservative).
4. Once the gel base (Step 2) has cooled to below 40°C, slowly add the liquid mixture from Step 3 to the gel base while stirring gently until fully combined and uniform.
5. Adjust pH if necessary (typically Pitera products have a pH between 4-7).
6. Pour the finished mask essence onto compressed mask sheets or store in a suitable container for use with dry mask sheets.

Note: The exact percentage of Galactomyces Ferment Filtrate within the liquid phase (Galactomyces Ferment Filtrate + Water + Preservatives) will determine the final concentration. Using a higher percentage of the Galactomyces Ferment Filtrate product will result in a more concentrated mask essence. Always ensure proper preservation for safety and shelf life. Sodium Salicylate is a water-soluble preservative but is often used in combination with other preservatives for broad-spectrum protection.
