Bio Gold is the most concentrated expression of what we believe about skin: that it is a lipid organ, and that the best thing you can do for it is give back — in forms it already recognises — what age, weather, and time remove. Golden jojoba (sebum-mimetic wax esters) and olive squalane are the structural backbone. Meadowfoam and prickly pear deliver oxidative stability and γ-tocopherol. Sea buckthorn CO₂ brings omega-7. Natural 99% bakuchiol — a botanical active extracted from babchi (Psoralea corylifolia) seeds — supports skin firmness and clarity over weeks of use, with a tolerability profile that suits daily application.
Why this product exists
We built Bio Gold as the answer to a specific question the ingredient-literate customer keeps asking: what does a serum look like that does not rely on silicones to feel good, does not rely on mineral oil to occlude, does not rely on seed oils that oxidise on the skin, and does not rely on a patented peptide complex whose evidence base is thin? The answer is in the nine ingredients on the label. No hidden fragrance. No hidden preservation. Water-free, because water-free needs no preservation system. Nine ingredients — every one you can defend at an ingredient-literate dinner party.
Ingredients
-
Golden Jojoba Oil (unrefined) 0% Approved — First-press, unrefined. Retains phytosterols and tocopherols that refinement removes. Wax-ester structure is a close match to human sebum — the skin recognises this as "skin lipid".
-
Olive Squalane 0% Approved — Structurally matches a lipid the skin already makes, so it integrates into the lipid film rather than sitting on top. Olive-derived, not sugarcane — a cleaner provenance story.
-
Meadowfoam Seed Oil (unrefined) 0% Approved — The most oxidatively stable botanical oil in the formula. The reason Bio Gold is preservative-free.
-
Prickly Pear Seed Oil (unrefined) 0% Approved — 1 kg of oil from 1 tonne of fruit — an unusually rare ingredient. ~60% linoleic acid, 403 mg/kg vitamin E (γ-tocopherol).
-
MCT Oil (C8/C10) 0% Approved — Base oil. Fast-absorbing, odourless, stable.
-
Sea Buckthorn CO₂ 0% Approved — Omega-7 palmitoleic acid. Documented to stimulate re-epithelialisation and improve skin moisture and elasticity in human studies.
-
Natural Bakuchiol (99%) 0% Approved — A botanical active extracted from babchi (Psoralea corylifolia) seeds. Peer-reviewed work documents improvements in fine lines, firmness, and tone with twice-daily use. Well-tolerated for morning and evening application; no sun-exposure restriction.
-
d-alpha Tocopherol 0% Approved — Natural vitamin E. Protects the formula's oxidative stability and contributes its own antioxidant behaviour on the skin.
-
Bergamot Essential Oil 0% Approved — Steam distilled, bergapten-free. Bright top note.
-
Geranium Essential Oil 0% Approved — Steam distilled. Floral middle; mild antimicrobial.
-
Rosemary Essential Oil 0% Approved — Steam distilled. Herbal lift; mild antioxidant. Each oil present in trace amounts — measured in drops. Very light scent that fades in 30–45 minutes.
How to use
- Apply 1–2 pumps to cleansed skin (morning or evening; we use it evening).
- Massage into face and neck until absorbed.
- Can be used alone or before SPF (morning) or as the last step (evening).
- One bottle is approximately 10–12 weeks of evening use.
What to expect
Week 1: skin feels softer, more even. Weeks 2–4: fine lines appear less pronounced, texture improves. Weeks 8–12: the cumulative benefits of bakuchiol become visible — uneven tone softens, firmness improves, skin clarity advances. This is a compounding product; the longer you use it, the better it works.
FAQ
Is Bio Gold available now?
Yes. Bio Gold ships from our current inventory. Free Thailand shipping.
How does it compare to Augustinus Bader The Serum?
Different formulation philosophy. Augustinus Bader is a peptide-led, water-based serum with a 36-ingredient label. Bio Gold is a lipid-led, water-free serum with a 9-ingredient label. Both are well-made; only Bio Gold is built without industrial seed oils, silicones, or petroleum derivatives.
Can I layer this with the actives I already use?
Yes. Bio Gold is a lipid-led serum, so it layers cleanly with most water-based actives. If you're using something particularly active, apply Bio Gold last so it seals everything in.
Is the formula friendly to sensitive skin?
Bio Gold is formulated without the ingredients that most commonly drive sensitivity flags — no synthetic fragrance, no preservatives (it’s water-free, so none are needed), no industrial seed oils, no silicones. As with any new topical, patch test first; for specific medical concerns, consult your doctor.
How is it different from Biossance Squalane + Rose Oil?
Biossance's product is primarily sugarcane squalane with a small rose oil addition. Bio Gold is nine ingredients deep, uses olive-derived squalane, and includes bakuchiol as the active — a materially deeper formulation.
Pairs with: Bio Clean (paired cleanser), Bio Glide + Bio Recovery (shave), PrimalDent.
