Why everyone's switching to tallow sunscreen
Tallow is everywhere right now for a reason: it's structurally close to the skin's own sebum, so it absorbs cleanly instead of sitting greasy on top. The problem is most tallow sunscreens were rushed to catch the wave — inconsistent SPF, vague sourcing, no batch testing.
Solsone is the slow version. Eighteen months in development. Eight ingredients we can name. Grass-finished tallow, non-nano zinc, broad-spectrum SPF 50 that tests accurately. Plus the fat-soluble vitamins (A, D, E, K) tallow naturally carries — so daily wear means softer, calmer, more even skin over time, not just UV protection.
The reason it's working isn't the trend. It's the formula.
Most "sunscreens" are doing more harm than the sun.
Here's what's actually in the bottle most people use every day - and why your largest organ is paying the price.
Hormone Ruiner 01
Chemical UV filters
The hormone disruptors hiding in plain sight. Oxybenzone, octinoxate, homosalate, avobenzone — all detected in blood and breast milk within hours of application. No Thank-you!
✓ Zero chemical UV filters. Ever.
Hormone Ruiner 02
Synthetic fragrance
"Fragrance" can legally hide over 3,000 undisclosed chemicals — including known endocrine disruptors. The leading cause of contact dermatitis on a sunscreen.
✓ Zero synthetic fragrance. Ever.
Hormone Ruiner 03
Skin-barrier saboteurs
Silicones, seed oils, and PEGs that suffocate pores, disrupt the lipid barrier, and trap zinc in clumps that cause white cast. Most "clean" SPFs are full of them.
✓ Zero silicones, seed oils, PEGs.
Eight ingredients. That's it.
We don't believe a sunscreen should have 40 ingredients. Bioshield has eight — every one chosen for what it does, sourced from a place we can name.
Non-nano zinc oxide (25%)
Pharmaceutical grade. Reflects UVA and UVB at the skin surface.
Grass-fed tallow
Regeneratively raised, Australia & New Zealand. Bioidentical lipids.
Organic Jojoba oil
Cold-pressed. Mirrors human sebum. Carries actives.
Organic beeswax
Natural water-resistance. Small-batch Oregon apiaries.
Lecithin
Plant-derived emulsifier. No PEGs, no silicones.
Tocopherol (vitamin E)
Naturally derived. Supports skin barrier.
Radish root ferment
Plant-based natural preservative. No parabens.
Silica
Naturally derived mineral that absorbs excess oil and smooths skin.
Three principles. One sunscreen.
BioShield Technology™ is what happens when you stop bolting mineral protection onto a skincare formula — and start designing the formula around the protection.
01
Reflect
25% non-nano zinc oxide
Reflects up to 97% of UVA and UVB at the surface of your skin. Non-nano particles stay where they belong — on top, doing their job.
🔗 Matta et al., JAMA, 2020
02
Restore
Bioidentical tallow
Grass-fed tallow is ~50% oleic and palmitoleic acid — the same fatty acids your skin already produces. Absorbs without greasing, restores barrier function.
🔗 PMC review, 2023
03
Disappear
Jojoba ester dispersion
We pre-coat every zinc particle with jojoba ester — a wax that disperses zinc evenly across the skin. Full protection, invisible finish.

“What's different about Bioshield is that the formula is built on real biocompatibility, it uses the same lipids your skin already produces. It's the most protective, biocompatible sunscreen I've ever seen on the market.”

★★★★★
The first mineral SPF that disappears.
"I'm Fitzpatrick V and I've given up on every mineral sunscreen because of the ghost-cast. Bioshield is the only one that vanishes. I bought 6 tubes after my first ran out."
★★★★★
My eczema didn't react.
"Three years of trying clean sunscreens and breaking out anyway. Bioshield is the first one I've used for a full month with no flare. I'm telling everyone."
★★★★★
Feels like a serum, not sunscreen.
"The texture is wild. Goes on like a moisturizer, sets in 60 seconds, no shine. I'm wearing it under makeup every day now."
Everything you might want to know.
Ingredients & safety
Yes — the formula is made with gentle mineral UV filters and skin-supportive ingredients, making it suitable for most kids and sensitive skin types. For children under 6 months, we recommend consulting your pediatrician before sunscreen use.
Yes — mineral sunscreen is generally considered the preferred option during pregnancy because it sits on the skin’s surface rather than being absorbed like many chemical sunscreens. If you have specific concerns, consult your healthcare provider.
Yes — the formula is made without oxybenzone or octinoxate, two commonly avoided sunscreen chemicals linked to coral reef damage.
Performance
For best protection, reapply every 2 hours when exposed to direct sunlight, and immediately after swimming, sweating, or towel drying.
SPF helps protect your skin from UV damage and reduces the likelihood of tanning, but no sunscreen can block 100% of UV rays. Extended sun exposure may still result in some tanning.
The formula is designed to blend smoothly into the skin with minimal white cast compared to traditional mineral sunscreens. Results may vary slightly depending on skin tone and application amount.
Use & application
Apply generously as the final step in your skincare routine. For the face and neck, we recommend about two finger lengths of product for proper SPF coverage.
The formula is designed to be gentle and non-irritating, especially compared to many chemical sunscreens. However, avoid direct contact with the eyes, as individual sensitivity can vary.
It has a soft, natural scent with subtle warm and botanical notes from the ingredients — without the strong “traditional sunscreen” smell.
