I will reformulate optimize or reverse engineer your cosmetic formula
Skincare and Haircare Formulation Specialist
About this Gig
I will reformulate or optimize your existing cosmetic product.
A formula that's almost right usually needs one or two changes, not a rebuild from scratch.
I'm Josephine, a cosmetic chemist with 7+ years in skincare and haircare. Reformulation work is often the fastest way to fix a product that's already close to working.
What I can fix:
- Replace an ingredient that's irritating, discontinued, or hard to source
- Bring cost per unit down without changing how the product performs
- Adjust texture or stability without starting the whole formula over
- Update a formula to meet a new market's regulatory or labeling requirements
Scope:
- Skincare: moisturizers, serums, cleansers, masks, balms
- Haircare: shampoos, conditioners, treatments, scalp products
Send me your current formula and what's not working, and I'll tell you what's fixable before you order.

FAQ
Do I need to share my existing formula?
Yes, the full ingredient list and percentages if you have them, or as much detail as you know. I can't optimize a formula blind.
What if I only have a product name or a short ingredient list, not percentages?
I can still help, but the fix will involve more assumptions. I'll flag upfront what's estimated versus confirmed.
Can you match a competitor's product?
I can build something with a similar feel and function. I won't reverse-engineer an exact copy of another brand's proprietary formula.
Do you provide physical samples?
No. Formulas are delivered on paper; testing and production happen with your co-packer or lab.
