Subject: Sample Formulation for Concentrated Cream / Sleeping Mask (Whitening & Dark Spot)

Hello!

Based on your request for a concentrated cream that can be used as a sleeping mask, focusing on skin whitening and reducing dark spots, here is a sample formulation incorporating the key ingredients discussed previously.

Please note that formulating cosmetics requires specific knowledge and equipment. This is a sample formula for your reference, and adjustments may be needed based on desired texture, stability, and performance.

Sample Formulation:

• Water: q.s. to 100% (Base)
• Glycerin: 5% (Humectant, Hydration)
• Beta Glucan: 5% (Hydration, Soothing)
• N-Acetyl Glucosamine: 4% (Helps reduce hyperpigmentation, improves skin hydration)
• Niacinamide (Vitamin B3): 5% (Brightens skin, improves skin barrier function, helps with dark spots)
• Azelaic Acid: 10% (Targets dark spots, reduces redness, has exfoliating properties. Note: Formulating with 10% Azelaic Acid can be challenging due to its solubility and potential for irritation. It may require specific solubilizers or dispersion techniques.)
• Allantoin: 0.5% (Soothing, helps skin healing)
• Licochalcone A: 1% (Soothing, antioxidant)
• Gotu Kola Extract: 5% (Soothing, helps with skin repair)
• Green Tea Extract EGCG: 5% (Antioxidant, soothing)
• Thickener (e.g., Aristoflex AVC): 1.5% (Provides texture and stability)
• Emollient (e.g., Caprylic/Capric Triglyceride): 5% (Improves skin feel, reduces greasiness)
• Preservative: 1% (Essential for preventing microbial growth)
• pH Adjuster (e.g., Lactic Acid or Sodium Hydroxide): q.s. to pH 5.0-6.0 (Optimal pH for stability and efficacy of actives)

Instructions (General):

1. Combine water phase ingredients (Water, Glycerin, Beta Glucan, N-Acetyl Glucosamine, Niacinamide, Allantoin). Heat gently if needed to dissolve solids.
2. Disperse thickener in the water phase or oil phase depending on the thickener type.
3. Combine oil phase ingredients (Emollient, Emulsifier - if using a cream base). Heat gently.
4. Combine water and oil phases (if making a cream) and emulsify.
5. Cool down the mixture.
6. Add heat-sensitive ingredients (Azelaic Acid - pre-dispersed/solubilized if needed, Licochalcone A, Gotu Kola Extract, Green Tea Extract EGCG, Preservative).
7. Adjust pH to 5.0-6.0.

This formulation combines potent whitening and dark spot ingredients with soothing and hydrating components suitable for a concentrated cream or sleeping mask. Remember to perform patch testing before using any new formulation.
