Biotin is the B vitamin famous for hair and nails — and the one where ORY® must be most careful about claims. Biotin is essential to the enzymes that build keratin, and true biotin deficiency causes hair loss and brittle nails that oral biotin reverses; but deficiency is rare, and a systematic review found no evidence that biotin improves hair or nails in healthy people [1]. The evidence for topical biotin is thinner still: it is water-soluble, poorly absorbed through skin, and no controlled study shows topical biotin grows hair. High-dose oral biotin also interferes with common laboratory tests, a safety issue dermatologists now highlight [2]. In cosmetics, then, biotin is a supporting, label-recognized nutrient — it hydrates modestly as a water-soluble vitamin, is stable and safe, and pairs with actives that do have evidence (caffeine, adenosine, rosemary, saw palmetto, panthenol). ORY® includes it for its nutrient story and keeps claims to “nourishes” rather than “grows.”
What is Biotin (Vitamin B7) made of?
Cosmetic biotin is synthesized to USP purity as D-biotin (the active isomer). Points to know [1, 3]:
- Water-soluble B vitamin (C₁₀H₁₆N₂O₃S): White crystalline powder; sparingly water-soluble (~0.02% cold; better warm or in glycol/mild alkali).
- Biological role: Coenzyme for carboxylases in fatty-acid and amino-acid metabolism — keratin synthesis depends on it internally.
- Topical penetration: Low; no controlled evidence of hair growth from topical use [1].
- Stable across pH 4–9 and heat; light-stable.
- Typical use: 0.01–0.1% (label-effective levels; higher levels do not add benefit).
What skin type is best suited for Biotin (Vitamin B7)?
Biotin is a gentle supporting vitamin suitable for all seven ORY® skin types:
- All skin types: Water-soluble nutrient with mild hydrating support; non-irritating; no skin-type restrictions.
- Dry: Supporting vitamin in hydrating serums.
- Sensitive: Non-sensitizing; safe.
- Oily, Acne-prone: Oil-free; non-comedogenic.
- Mature, Normal, Combination: Nutrient positioning in serums and creams.
What hair type is best suited for Biotin (Vitamin B7)?
Biotin is a supporting, label-recognized scalp nutrient — paired by ORY® with evidence-backed actives:
- Mature or thinning: Supporting nutrient alongside caffeine, adenosine, rosemary, and saw palmetto; no independent topical growth evidence [1].
- Dry or damaged: Water-soluble vitamin in conditioners (mild hydration).
- Straight, wavy, curly, coily: Nutrient addition for all.
- Oily, sensitive, dandruff-prone scalp: Neutral, non-irritating.
- Color-treated: Neutral.
What are the benefits of Biotin (Vitamin B7)?
Biotin’s cosmetic benefits are modest and must be stated honestly [1–3]:
- Nutrient support: Essential keratin-metabolism coenzyme (internally).
- Mild hydration: Water-soluble vitamin in aqueous phases.
- Safety and stability: Non-irritating; pH- and heat-stable.
- Consumer recognition: Strong “hair vitamin” association.
- Pairing value: Complements actives with evidence (caffeine, adenosine, panthenol).
- Oral relevance (not cosmetic): Reverses hair/nail effects of true deficiency only [1].
