Cosmetic Formulator, Custom Formulas, INCI And Private Label
About this Gig
Is your cosmetic or skincare formula separating, irritating skin, losing potency, or failing to scale up for production?
I troubleshoot and fix formulation problems for brands, indie sellers, and first-time founders turning a formula that's failing into one that actually performs.
Whether you built the formula yourself, inherited it from a supplier, or got it from a lab that didn't get it right, I'll tell you exactly what's wrong and fix it, not just flag the problem and leave you stuck.
What I fix:
- Separation, poor texture, or unstable emulsions
- Preservative failure or contamination risk
- Unstable actives (Vitamin C, Retinol, Niacinamide, etc.)
- Irritation or poor skin feel
- Scale-up failures from home batch to commercial production
- Ingredient conflicts or compatibility issues
What you get:
- Full technical review of your existing formula
- Root-cause diagnosis of what's actually going wrong
- Corrected, reformulated version with INCI + percentages
- Updated preservative system and pH range
- Manufacturing notes for a stable re-batch
Message me with your current formula and the issue you're seeing, so I can confirm scope and the right package.

FAQ
Do you need my exact current formula?
Yes, send your INCI list and percentages if you have them. If not, describe the product and issue clearly and I'll work from there.
Can you fix a formula that's already in production?
Yes, I can review a formula that's already being sold and correct it for future batches.
Will you tell me exactly what was wrong?
Yes, every package includes a clear explanation of the root cause, not just a corrected formula.
Is this different from your custom formulation gig?
Yes, this gig is for fixing or improving an existing formula. For a brand-new product built from scratch, check my custom formulation gig.
