FORMULATED IN BANGKOK · MANUFACTURED IN THAILAND

At 49, I weighed 280 pounds. I couldn't find personal care products I trusted, so I started making my own.

PrimalBasics is a house of skincare and personal care, held to The 0% Standard™ — fourteen non-negotiable exclusions across every formula. Our manufacturing partner is MSRI — a research institute within Prince of Songkla University in southern Thailand.

THE 0% STANDARD™

What we don't include is as specific as what we do.

We publish everything we exclude — and we hold that standard across every product, every batch, every formulation we have ever made. The list below is divided into universal exclusions (in every product) and category-specific exclusions (where the chemistry makes them relevant). It is enforceable, verifiable on the label, and it is the one thing we do not compromise on.

Universal — in every PrimalBasics product:
0% industrial seed oils · 0% synthetic fragrance · 0% hexane · 0% phthalates · 0% parabens · 0% triclosan · 0% sodium lauryl sulfate · 0% propylene glycol · 0% silicones · 0% petroleum derivatives
Category-specific — where chemistry makes them relevant:
0% aluminium (deodorant) · 0% baking soda (deodorant) · 0% fluoride (oral care) · 0% DEET (insect repellent)

Manufactured by a research institute within one of Thailand's leading universities.

  • A research institute, not a private factory.

    MSRI is embedded inside Prince of Songkla University — one of Thailand's top-tier research universities, with recognised programmes in natural products and tropical medicine.

  • Academic-grade quality protocols.

    We are transitioning the entire PrimalBasics range to MSRI's research-grade manufacturing — documented protocols, validated methods, and academic-grade QC that goes well beyond what a private contract factory provides.

  • A verifiable supply chain.

    A materially stronger supply chain than almost any clean-luxury peer can credibly claim — and as each product moves to MSRI, the proof appears on the label, not in a press release.

What customers say

  • Supriya · Bangkok

    “My skin is calmer, my ritual is shorter, and I throw away far fewer half-used bottles. That's the whole thing for me.”

  • Marcus · Phuket

    “I tried Bio Gold expecting another expensive bottle. It is not another expensive bottle. It is the first face oil that I have not run out before I wanted to buy it again.”

  • Chayada · Bangkok

    “ผิวสงบลง กลิ่นหายไป ความมั่นใจกลับมา” — “Skin calmed down, the smell disappeared, the confidence came back.”
