Evaluation of Your Eye Serum Formula for Puffiness

Thank you for sharing your revised serum formula for non-allergic eye puffiness. This formula includes several ingredients beneficial for the eye area, and the adjustments you've made address some of the points raised in the previous feedback.

Here's an evaluation of your proposed formula:

• Effective Ingredients for Puffiness: The inclusion of Coffee Extract and Boswellia Serrata Extract is excellent for addressing eye puffiness not caused by allergies. Coffee Extract is known to stimulate microcirculation, which helps reduce puffiness and dark circles caused by poor blood flow. Boswellia Serrata Extract has anti-inflammatory properties and can help with both puffiness and dark circles. Safe-B3™ (Niacinamide) also contributes by improving blood flow.
• Skin Tightening and Soothing: DMAE is included for its skin-tightening benefits, which can help improve the appearance of the eye area. Panthenol (Pro Vitamin B5) is a good addition for its moisturizing and soothing properties, which are important for the delicate skin around the eyes and can help counteract potential irritation from other active ingredients.
• Texture and Stability: Adding AnyGel™ as a gelling agent will help create a suitable serum texture and improve the stability of the formulation, addressing the previous feedback about the formula being too liquid.
• Preservation: The inclusion of Mild Preserved Eco™ ensures the formula is properly preserved.

Suggested Adjustments Based on Feedback and Ingredient Properties

Based on the staff's suggestions and the properties of the ingredients, consider the following adjustments to optimize the formula and minimize potential irritation, especially for the sensitive eye area:

• GlucoBright™: The staff recommended using GlucoBright™ at 2-4%. Your current formula uses 1%. Increasing it to 2% could enhance potential brightening effects if desired.
• Propylene Glycol: The staff recommended reducing Propylene Glycol to 2-3%. Your formula uses 12%. High concentrations of glycols can sometimes cause irritation, particularly around the eyes. Reducing it to 3% as suggested by the staff is advisable for gentleness. Please note that the product description for Boswellia Serrata Extract indicates it requires at least 6 times its amount of Propylene Glycol for solubility (meaning 12% Propylene Glycol for 2% Boswellia). While the staff indicated the formula can be mixed, reducing Propylene Glycol significantly might affect the solubility of the Boswellia extract. You may need to ensure it is well dispersed or consider if a lower concentration of Boswellia is acceptable if you reduce the Propylene Glycol significantly.
• Slim-Coffee™: The product description for Coffee Extract recommends a usage rate of 1% for the eye area. Your formula uses 3%. While a higher concentration might offer stronger effects, it also increases the risk of irritation on the delicate skin around the eyes. Consider reducing this to 1% or performing a patch test to assess tolerance.

Overall, your revised formula is a good base for an eye serum targeting puffiness. By considering the suggested adjustments, particularly regarding Propylene Glycol and Slim-Coffee™ concentrations for eye area sensitivity, you can create a more optimized and gentle product.
