Brush On Block Mineral Sunscreen Powder Refill — Translucent SPF 30, Lightweight Broad-Spectrum & Reef-Friendly

Brush On Block Mineral Sunscreen Powder Refill is a translucent, reef-friendly SPF 30 mineral powder designed to refill your self-dispensing brush for lightweight, non-greasy face protection.

Keep your Brush On Block brush topped up with this plastic-free refill of natural mineral powder sunscreen. Formulated to sit sheer on skin while offering broad-spectrum UVA/UVB coverage, the refill is an eco-conscious way to maintain daily facial sun protection without sticky lotions or white cast. The powder is water-resistant and free of common chemical sunscreens that harm reefs, making it a travel- and ocean-friendly choice.

How does this refill work with the Brush On Block brush?

The refill is designed to be poured into the empty chamber of the self-dispensing brush so you can restore the powder-based applicator quickly. Its fine mineral texture flows easily through the brush’s mechanism, letting you sweep a consistent veil of SPF onto the face whenever you need a boost.

• Pour-and-twist refill format fits original Brush On Block brush
• Fine, talc-free mineral powder disperses evenly through bristles
• No mess reloading—minimal spills when following directions
• Maintains brush’s self-dispensing function for on-the-go use

Will the powder change my skin tone or feel heavy?

This translucent formula is engineered to be sheer and lightweight, so it won’t noticeably alter skin tone or feel greasy. It layers invisibly over makeup and bare skin, offering a matte, natural finish that’s suitable for daily touch-ups.

• Translucent finish blends with most skin tones
• Powder format reduces shine and oily feel
• Works well over makeup for midday reapplication

Is this product safe for sensitive skin and the environment?

The refill contains natural mineral actives and avoids parabens, PABA, phthalates, oxybenzone, and octinoxate, lowering irritation risk and complying with reef-friendly guidelines. It’s formulated for sensitivity-conscious users who prefer mineral protection without common chemical UV filters.

• Vegan-friendly and free from parabens, PABA, and phthalates
• Hawaii-compliant, oxybenzone- and octinoxate-free reef formula
• Mineral-based SPF 30 for broad-spectrum UVA/UVB coverage

How long does the protection last and how should I reapply?

The powder provides water-resistant SPF 30 protection when applied properly, but like all sunscreens, it should be reapplied after heavy sweating, swimming, or towel-drying. Use the brush to refresh coverage every two hours for extended sun exposure or as needed during the day.

• Broad-spectrum SPF 30 with water resistance for active days
• Reapply after swimming, heavy sweating, or towel drying
• Convenient brush makes quick touch-ups practical and clean

Who is this for? The Brush On Block Mineral Sunscreen Powder Refill is ideal for people who prefer mineral-based sun protection, want a refillable, low-waste option, or need a portable, non-greasy way to reapply SPF during the day. It suits sensitive skin types, reef-conscious travelers, makeup wearers seeking invisible sun coverage, and anyone who likes the convenience of a self-dispensing brush for on-the-go protection.
