Custom Serum Formulation Review Request

Question

Hello,

I am planning to order production for a serum based on the public Hyaluron Serum (Preservative-Free) formula, but with added ingredients and adjusted percentages. I would like to request that your staff review the formula before I place the production order today to ensure it is viable, as I want to use the exact ingredients and percentages listed below.

My proposed formula is:

Hyaluronic Acid (Standard Molecule) / 0.30
Hyaluronic Acid (Large Molecule) / 0.50
Hyaluronic Acid (Small Molecule) / 0.30
HyaCoat Skin / 0.20
Glycerin 99.5 / 5
Mild Preserved Eco / 2
Safe-B3 / 10
Panthenol (Pro Vitamin B5) / 1
Ammonium Lactate / 1
MOIST72 / 1
HydroAlgae / 1
Zinc PCA / 1
GlucoBright / 4
น้ำกลั่น / 72.7

I have previously used the public Hyaluron serum formula and liked its moisturizing, non-sticky feel. I want to increase the percentage of B3 and add Zinc PCA, using percentages similar to The Ordinary. I also added GlucoBright to enhance brightening, as the formula already contains B3.

Based on this, can this formula be produced?

My skin type is dehydrated, with some clogged and inflamed acne, acne marks, and is combination (oily T-zone).

Subject: Review of Custom Serum Formulation

Hello,

Thank you for providing your custom serum formulation based on the public Hyaluron Serum recipe. You've listed the ingredients and their desired percentages, which sum up to 100%.

Your formula includes a good range of hydrating ingredients (various Hyaluronic Acid types, HyaCoat, Glycerin, Panthenol, MOIST72, HydroAlgae) and adds actives like Safe-B3 (Niacinamide) at 10%, Zinc PCA at 1%, and GlucoBright (N-Acetyl Glucosamine) at 4% for brightening, oil control, and anti-acne benefits, which aligns with your skin concerns.

Based on typical cosmetic ingredient usage rates:

Niacinamide (Safe-B3) at 10% is a high concentration, although used in some popular products.
Zinc PCA at 1% is within the common range.
N-Acetyl Glucosamine (GlucoBright) at 4% is at the higher end of the common range.

Combining multiple potent actives like Niacinamide (10%), Zinc PCA (1%), and N-Acetyl Glucosamine (4%) in one formula can be effective, but it also may increase the potential for skin irritation, especially given your skin type (combination, some inflammation/acne). While these concentrations are individually plausible, their combination requires careful consideration.

As an AI, I can review the formula based on general knowledge of cosmetic ingredients and their typical usage, but I cannot definitively approve it for production. A professional assessment by our production staff or a qualified formulator is essential to ensure the formula's:

Stability: Will the ingredients remain stable and effective over time in this combination?
Compatibility: Do all ingredients work well together without undesirable reactions or precipitation?
Safety: Is the formula safe and non-irritating for typical use, especially at these concentrations of actives?
Manufacturability: Is it technically feasible to produce this formula consistently?

Therefore, while your proposed formula seems interesting and targets your skin concerns, I highly recommend submitting it directly to our production staff for their expert review, stability testing, and safety assessment before proceeding with manufacturing. They will be able to provide the final confirmation on whether the formula is viable for production as is or if any adjustments are needed.

We appreciate you consulting us before placing your order!
