Essence Formula Feedback

Thank you for sharing your essence formula. It includes several beneficial ingredients for skin.

Based on the product information available:

• Vitamin B3 (Niacinamide): Effective for reducing wrinkles, hyperpigmentation, improving skin barrier, controlling oil, and anti-inflammatory effects. The recommended pH range is 3-8 (best at 4.0-7.0).
• Glucosamine (N-acetyl-D): Works well with Niacinamide for whitening and reducing dark spots. It also stimulates Hyaluronic Acid production. The recommended pH range is 3-7.
• Panthenol (VB5): Acts as a humectant, moisturizes, reduces inflammation, helps wound healing, and improves skin elasticity. The appropriate pH is 3.5-7.0.
• Zinc PCA: Helps reduce oiliness, accelerates wound healing, stimulates collagen, and can help with dandruff. It is highly soluble at pH 4-6, and precipitation may occur outside of this range. The product itself has a pH of 5-6.
• Allantoin: Known for reducing irritation, soothing skin, and promoting tissue regeneration. It is best used at pH 4-8, with a range of 3-8 being acceptable.
• Natural Betaine: Provides moisture, reduces irritation, strengthens the skin barrier, and helps dissolve Allantoin. The recommended usage rate is 2-10%.
• Glycerin: A common humectant and solvent, used to add moisture and smoothness. Can be used at 1-100%.
• Phenoxyethanol: A preservative effective against bacteria, best used at a pH between 2-9.

Regarding pH compatibility, most of the ingredients (Vitamin B3, Glucosamine, Panthenol, Allantoin, Natural Betaine, Glycerin, Phenoxyethanol) have overlapping recommended pH ranges, generally falling within the 3-8 range. However, Zinc PCA has a more specific optimal solubility range of pH 4-6. To ensure all ingredients remain stable and effective, you would ideally aim for a final formula pH that accommodates all components, particularly the more sensitive ones like Zinc PCA.

Important Considerations:

• While the individual ingredients have known benefits and general pH guidelines, the interaction of all components in your specific concentration and order of addition can affect the final pH and stability. It is highly recommended to measure the pH of your finished formula and adjust it if necessary to be within a range that supports the stability and efficacy of all active ingredients, especially considering the optimal range for Zinc PCA (4-6).
• Evaluating the overall efficacy, stability, and safety of the complete formula requires laboratory testing, which is beyond the scope of this information.

Regarding the availability of Ceramide Complex, Xanthan Gum, Argan Oil, and Royal Jelly Fresh, I do not have access to real-time inventory information. Please check the website directly or contact customer service for the most up-to-date stock status.

I hope this information about the individual ingredients is helpful for your formulation process.
