Custom Cream Formulation Advice

Regarding your request to create a custom tester cream with Pure Aloe base and adding the specified active ingredients at the given percentages:

1. Can all ingredients be added at the specified concentrations (total 27%)?
   Adding a total of 27% active ingredients to a base like Pure Aloe may exceed the maximum concentration limit for custom formulations on the website. While the individual concentrations you selected (Vitamin B3 5%, Glucosamine 4%, Sea Kelp Bioferment 10%, Matrixyl 3000 5%, Pepha-Tight 3%) are generally within the recommended usage ranges for each ingredient, the combined total is quite high. It's important to adhere to the website's guidelines for custom testers to ensure the stability and effectiveness of the final product.

2. Can this cream be used day and night?
   Yes, the combination of ingredients you've chosen is generally suitable for both daytime and nighttime use. Vitamin B3, Glucosamine, Sea Kelp, Matrixyl 3000, and Pepha-Tight do not typically cause photosensitivity. However, it is crucial to always apply sunscreen as the final step in your morning routine when using this cream during the day.

3. Recommendations for adjusting the formula:
   Your skin concerns include combination oily T-zone, dehydration, large pores, dullness, roughness, and wrinkles. The ingredients you selected are well-chosen to address these issues:

   • Vitamin B3 (Niacinamide): Excellent for reducing oiliness, minimizing pores, improving dullness, and reducing wrinkles. 5% is a good effective concentration.
   • Glucosamine (N-acetyl-D): Works synergistically with Vitamin B3 for brightening and improving skin hydration and texture. 4% is an appropriate concentration.
   • Sea Kelp Bioferment: Provides hydration and nourishment, beneficial for dehydrated skin. The requested 10% is at the higher end of the recommended range (typically 1-3% for skin) and might contribute to a strong scent or affect texture. A lower percentage might still provide hydration benefits.
   • Matrixyl 3000 & Pepha-Tight: Both are effective peptides for targeting wrinkles and improving skin firmness. Using both can provide comprehensive anti-aging benefits.

   To stay within typical custom formulation limits and create a balanced product, consider adjusting the percentages. A suggested revised formula that still targets your concerns effectively could be:

   • Vitamin B3: 5%
   • Glucosamine (N-acetyl-D): 4%
   • Sea Kelp Bioferment: 3%
   • Matrixyl 3000: 3%
   • Pepha-Tight: 3%

   This combination totals 18% active ingredients, which is more likely to be compatible with a standard base and within typical custom formulation limits, while still providing significant benefits for hydration, pores, dullness, and wrinkles. You could also consider adding a hydrating ingredient like Sodium Hyaluronate at a low percentage (e.g., 0.1-0.5%) if dehydration is a major concern, provided the total percentage remains within limits.

Remember to check the specific maximum total active ingredient percentage allowed for custom testers on the website before finalizing your order.
