Plain-language, fear-free technical guidance for indie and natural-leaning skincare brands — from a working cosmetic chemist who formulates, writes and teaches in Gqeberha, South Africa.
Three ways to work together — whether you are commissioning your first formula or checking the claims on a label that already exists.
Technical Guidance
An honest, second pair of eyes on the technical side of your product — before you spend money on a run you cannot sell.
Ingredient and INCI list review
Claims and copy accuracy review
Formula feasibility checks
Interpreting TDS, COA and stability reports
Product briefs you can hand to a lab
Formulation Design
Theoretical formulas built around your brief, your budget and the ingredients you actually want to use — with the reasoning written out.
Theoretical formula development
Anhydrous formulations — balms, butters, oils
Ingredient substitution and cost guidance
Phase, process and packaging notes
Handover documentation for your lab
Workshops
Hands-on sessions in Gqeberha and online, for makers who want to understand what they are doing rather than follow a recipe blindly.
Lip balm making
Candle making
Read an ingredient list like a chemist
Small-group and private bookings
Beginner-friendly, no chemistry background needed
Lab testing — stability, challenge and compatibility testing — is arranged through accredited partner laboratories. I prepare the brief, interpret the results and tell you what they mean for your product.
Hi, I'm Aamina.
I am a cosmetic chemist based in Gqeberha, South Africa, and the person behind Amino Molecule. I started this studio because too much skincare advice online is either technically wrong or designed to frighten you — and neither helps you make a better product.
I hold a Diploma in Personal Care Formulation and I am the founder of the skincare brand Luyun, so I know what it is like to sit on the other side of the bench: the sampling, the stability wait, the label that has to be right the first time.
I also write the Amino Molecule blog, where I unpack ingredients, INCI names and marketing claims in the same plain language I use with clients. No fear-mongering, no miracle claims — just what the science actually supports.

Writer of the Amino Molecule blog and Claim Check series
Learn
Free, accurate cosmetic science writing — for founders who want to understand their own products, and for anyone curious about what is really in the bottle.
Claim Check
Claim Check: "chemical-free"
Why the phrase cannot be true, what it usually means in practice, and how to write a claim that is honest and still sells.
Regular posts on ingredients, claims, formulation and the business of making skincare — written for people who are not chemists.
Ingredient glossary
A growing plain-language glossary of INCI names, what they do in a formula, and which ones are worth the money.
Claim Check series
One marketing claim at a time, examined against the evidence — what it can say, what it cannot, and how to phrase it legally.
Workshops
Small, hands-on sessions where you make something real and leave understanding why it works. All materials are provided, and every workshop ends with a written recipe and notes you can keep.
Working with brands at the very start of their formulation journey.

Aamina read my INCI list and found two claims I could not legally make. She rewrote them in a way that still sounded good — and explained exactly why the originals were a problem.

I had a formula I loved and no idea whether it was stable. The feasibility check saved me from ordering packaging for a product that would have separated in three months.

The lip balm workshop was the first time chemistry made sense to me. I now formulate my own balms and I understand every ingredient I put in them.

Let's talk about your product
Tell me where you are in the process — an idea, a half-finished formula, or a label that needs checking. I will reply with an honest view of what you need next.
