Bakuchiol is a plant-derived compound extracted from the seeds and leaves of the Psoralea corylifolia plant. Published clinical studies show it delivers similar anti-aging benefits to retinol — stimulating collagen production, reducing fine lines, and improving skin texture — without retinol's common side effects of dryness, peeling, and photosensitivity.

This makes Bakuchiol suitable for sensitive skin types and safe to use during the day, unlike traditional retinol which must be used at night and requires sun avoidance.

Astaxanthin is a keto-carotenoid antioxidant naturally found in microalgae. It is considered one of the most powerful antioxidants in nature — research suggests it may be significantly stronger than Vitamin C at neutralizing free radicals.

In skincare, it has been clinically shown to reduce the visible signs of aging, improve skin moisture and elasticity, and protect against UV and environmental damage. It gives our formula an exceptional level of antioxidant protection.

Yes. All Biotite ingredients are plant-derived botanicals — oils, essential oils, and plant extracts. We use no synthetic fillers, harsh chemicals, or artificial preservatives. Every ingredient is chosen for a specific scientific purpose and nothing is added to bulk out the formula.

Our founders' backgrounds in pharmaceutical manufacturing and medical science mean we apply the same rigorous standards to formulation that you'd expect from a clinical product — but with an entirely natural ingredient list.

The full ingredient list is printed on the product label and is available on each product's page on our website. You can also visit our Ingredients page for a detailed breakdown of each ingredient and its benefits, and our Science page for the peer-reviewed publications behind them.

Ingredients may occasionally be updated as we refine our formulas or as ingredient availability changes. Always refer to the product label or website for the most current list.

Yes — Biotite Antioxidant Oil is safe and effective for both morning and evening use. Unlike traditional retinol products, Bakuchiol does not cause photosensitivity, so there is no restriction on daytime use.

If using in the morning, we recommend applying a broad-spectrum SPF over the top as the final step of your routine to protect against UV damage.

As a general rule, facial oils are applied after water-based products (serums, essences, toners) and before or instead of a moisturiser. A simple routine order would be:

• Cleanse
• Toner / essence (if used)
• Water-based serum (if used)
• Biotite Antioxidant Oil
• Moisturiser (optional — many find the oil sufficient)
• SPF (morning only)

If you're unsure, start with just cleanser + Biotite + SPF in the morning to see how your skin responds.

4–5 drops is sufficient to cover your full face and neck. A little goes a long way with a concentrated botanical oil — using too much may leave a greasy finish. Start with 3–4 drops and adjust based on your skin's preference.

Many customers notice improved hydration and a healthy glow within the first week of consistent use. For more significant results — such as reduced fine lines, improved texture, and evening of skin tone — allow 4–8 weeks of daily use.

Skincare results vary between individuals based on skin type, age, lifestyle, and consistency of use. For best results, use Biotite as part of a consistent daily routine.

Yes. Biotite Antioxidant Oil is designed to complement an existing skincare routine. It pairs well with most cleansers, toners, moisturisers, and SPFs.

If you use active ingredients such as AHAs, BHAs, or Vitamin C, apply those first (as they are typically water-based), then follow with Biotite. As with introducing any new product, we recommend adding one new product at a time to your routine so you can identify how your skin responds.
