Biotin, Pure 99.7%: The Beauty Vitamin Your Formulations (and Skin) Need

Why Biotin Is More Relevant Than Ever

In a beauty industry packed with trends, buzzwords, and miracle promises, some ingredients stand the test of time. Biotin—also known as Vitamin B7 or Vitamin H—is one of them. Biotin has long been a staple in supplements for healthy hair, skin, and nails—but in 2025, it’s making a comeback in topical form, gaining new attention for its direct-to-skin benefits.
At Bulk Naturals Wholesale, we’re seeing more brands—from minimalist clean-beauty startups to advanced cosmeceutical lines—rely on high-purity Biotin, Pure 99.7% to develop products that deliver visible results without complexity. Whether you’re formulating your next bestseller or shopping for ingredients to support your personal care routine, biotin belongs on your radar.

What Is Biotin—and Why Does It Matter?

Biotin is a water-soluble B-vitamin that plays a key role in converting nutrients into energy, particularly in the metabolism of proteins, fats, and carbohydrates. This energy is essential for producing keratin, the primary structural protein in hair, skin, and nails.

Most people associate biotin with oral supplements—but when used topically in the right form and concentration, it can deliver targeted results right where your body needs it most. Think: a cuticle serum that strengthens nails over time, or a scalp mist that supports growth at the root.
And because your body doesn’t store biotin, topical replenishment is more than just a trend—it’s a smart, science-backed strategy.

For Consumers: What Can Biotin Do for Your Routine?

If you’re shopping for products that contain biotin, you’re looking for more than just a cosmetic fix. You’re likely dealing with breakage, dryness, brittleness—or all of the above. And you want solutions that feel natural, gentle, and effective.
Here’s what biotin can support:

✨ Hair: From Thinning to Thriving
Biotin helps reinforce the keratin structure in your strands and scalp. If you’ve noticed more hair in your brush lately—or your texture feels weak and over-processed—biotin can be a game-changer. It’s commonly included in:
  • Scalp serums for density and follicle health
  • Strengthening conditioners and masks
  • Leave-ins that repair without weighing down
  • Clean, fragrance-free shampoos for sensitive scalps
✨ Skin: The Glow You’ve Been Missing
Biotin supports skin cell regeneration, oil balance, and barrier resilience. It’s not as famous in skincare as niacinamide or hyaluronic acid—but it quietly boosts hydration, elasticity, and smoothness, especially in:
  • Barrier-repair night creams
  • Rehydrating toners with aloe and B-complex
  • Post-exfoliation calming serums
  • Lip or eye-area care for stressed skin
✨ Nails: Stronger, Smoother, Less Breakage
Say goodbye to peeling and chipping. Topical biotin encourages better keratin production in your nail beds, leading to smoother, stronger growth over time. You’ll find it in:
  • Fortifying hand creams
  • Nail & cuticle serums
  • At-home manicure treatments
  • Dry oil blends for nail health

Common Biotin FAQs 

Q: How long until I see results from biotin in my skincare or haircare?
Most users report improved smoothness and hydration within 2–4 weeks. For hair and nails, expect 6–12 weeks for noticeable strength and growth.
Q: Will it make me break out?
Biotin is typically well-tolerated, especially at topical concentrations. If you’re sensitive, start with a lower concentration and avoid combining with heavy comedogenic oils.

How to Formulate with Biotin

Biotin (Vitamin B7) is a powerhouse ingredient for supporting skin health, hair growth, and nail strength—but its physical properties require a bit of extra care when formulating. Because biotin is insoluble in oil and only sparingly soluble in water, it can’t simply be mixed into every type of formulation. Here’s how to work with it effectively:

✅ Use in Emulsions and Water-Based Formulas

The best way to incorporate biotin is in oil-in-water (O/W) emulsions, such as lotions, creams, or lightweight serums. In these formulas, biotin is added to the water phase, where it can be dispersed (even without fully dissolving) and remain bioavailable at low concentrations—typically between 0.01% to 0.1%.

Usage Rates

  • 0.01–0.1% in general skincare and haircare
  • 0.1–0.2% in nail-focused or targeted treatments

Using an emulsifier helps bind the oil and water phases together, allowing the biotin to be delivered evenly throughout the formula.

💡 Tip: Make a lightweight lotion or serum using an O/W emulsifier like Olivem 1000 for sprays.

💧 Suspension in Gels or Serums

Another effective method is suspending biotin in a thickened water-based gel, such as an aloe vera serum or toner. Using natural thickeners like xanthan gum can help keep the biotin dispersed and stable, even without full solubility.

🚫 Not for Anhydrous Formulas

Since biotin does not dissolve in oils, it’s not suitable for anhydrous products like facial oils, body butters, or balms—unless you’re using more advanced techniques like encapsulation (e.g., liposomes), which require special equipment and ingredients.

🧪 Pro Formulator Tip:

Always add biotin to the heated water phase of your formulation to help it dissolve more efficiently, and blend thoroughly before emulsifying. For spray formulas or toners, a solubilizer may be needed to keep the formula uniform.

✅ Ingredient Pairing
Biotin synergizes beautifully with:
