Most mineral sunscreens sit on top of your skin, leaving a heavy, chalky layer that breaks down the moment humidity hits. Sol No. 15 was formulated differently — as a tallow-based, anhydrous sun balm that mimics your skin's natural lipid structure to deliver broad-spectrum UVA/UVB protection with a breathable, velvet-matte finish. Designed specifically for hot, humid climates, this natural face sunscreen absorbs quickly and stays put — even under heat and sweat. Key Benefits: Broad-spectrum mineral protection — non-nano zinc oxide provides a physical UV barrier against UVA and UVB rays without chemical filters like oxybenzone or avobenzone Grass-fed tallow — closely mirrors human sebum; delivers fat-soluble vitamins A, D, E & K for deep nourishment that prevents the tight, parched feeling of prolonged sun exposure Dry-touch, sheer finish — Kokum butter creates a lightweight, non-greasy texture; iron oxides and cacao neutralize zinc's white cast for a skin-tone-adaptive glow Essential oil-free, synthetic fragrance-free, minimalist ingredient list How to Use Sol No. 15: Apply as the final step in your morning routine Warm a pea-sized amount between your fingertips until it transforms into a silky, fluid oil Press gently into the face, neck, and décolletage Reapply every two hours or after sweating for continuous protection Pairs beautifully with Milk No. 0 (cleanser) and Dew No. 12 (toner) as the third step in your morning ritual. The Bath Shoppe Glossary of Clean Ingredients Adeps Bovis (Grass-Fed Tallow)The hero of the formula. Tallow's lipid profile closely mirrors human sebum, allowing fat-soluble vitamins A, D, E & K to absorb efficiently — delivering deep nourishment rather than sitting on the surface. Simmondsia Chinensis (Jojoba) OilA liquid wax ester that ensures a dry-touch finish. Helps regulate natural oil production and prevents the heavy, slick feeling common in other oil-based sunscreens. Garcinia Indica (Kokum) ButterA non-comedogenic butter that provides the firm structure of the balm with a high melting point — keeping Sol No. 15 stable in Texas heat while leaving a non-greasy finish. Cera Alba (Beeswax)Locally sourced to provide a natural, breathable water-resistant barrier. Keeps the minerals in place on your skin while you sweat. Non-Nano Zinc OxideA safe, mineral-based physical shield. Non-nano particles sit safely on top of the skin to reflect UVA and UVB rays without being absorbed into the bloodstream. Tocopherol (Vitamin E)A potent antioxidant that protects the skin from UV-induced free radical damage and acts as a natural preservative for the botanical oils. Cacao PowderUsed in its raw form to provide a warm, natural tint that neutralizes zinc's white cast — allowing the balm to blend seamlessly into the skin. Storage: Store in a cool location. If the balm softens in warm temperatures, place in the fridge for 20 minutes to restore consistency.
