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

This refill delivers the same light, mineral-based broad-spectrum shield you expect from Brush On Block without the plastic waste of a full new dispenser. Formulated for sensitive skin, the translucent powder blends invisibly over makeup or bare skin, resists water, and complies with Hawaii reef-safety standards by avoiding oxybenzone and octinoxate. It’s an economical, travel-ready way to maintain daily sun defense on the go.

How do I refill my Brush On Block brush easily?

Refilling is straightforward and mess-minimizing: remove the old sponge insert, pour in the powder refill, and reassemble the brush. The design keeps powder contained so you can refill without coating your counter or bag. It’s intended to be a simple swap that restores full dispensing performance.

• Remove twist cap and extract old refill sponge
• Pour powder slowly into the reservoir to avoid spills
• Replace sponge and cap, then prime brush with gentle presses
• No tools required—finished in minutes

Will the translucent powder change my skin tone or makeup?

The formula is sheer and designed to sit invisibly on a wide range of skin tones, so it won’t leave a white cast or alter foundation color. It dusts on smoothly and can be applied over makeup for midday touch-ups. Because it’s a mineral powder, coverage is matte and natural rather than creamy or oily.

• Translucent finish blends with most complexions
• Works over foundation, tinted moisturizers, or bare skin
• Matte texture controls shine without cakey buildup
• Suitable for quick midday reapplication

Is this refill safe for sensitive skin and ocean environments?

The ingredient profile focuses on non-chemical mineral actives and excludes common irritants such as parabens, PABA, and phthalates. It’s labeled vegan-friendly and formulated to be gentle for many sensitive skin types. Additionally, the powder meets reef-safety guidelines by avoiding oxybenzone and octinoxate, reducing impact on marine ecosystems where those ingredients are restricted.

• Mineral-based SPF 30 provides broad-spectrum protection
• Free from parabens, PABA, and phthalates
• Hawaii-compliant, reef-friendly formulation
• Vegan-friendly and created for sensitive skin tolerance

How long does protection last and how should I reapply?

The refill restores the Brush On Block brush to deliver SPF 30 mineral coverage; reapplication frequency depends on exposure and activity. For routine daytime use, reapply after heavy sweating, towel drying, or several hours outdoors. The brush format makes it convenient to refresh protection without sticky residue.

• Provides SPF 30 broad-spectrum protection per application
• Reapply after swimming, sweating, or extended sun exposure
• Ideal for quick touch-ups throughout the day
• Water-resistant but reapplication advised after water exposure

Who this refill is for: Anyone who already owns—or plans to buy—a Brush On Block brush and wants a sustainable, portable way to maintain daily sun protection. It’s especially suitable for people who prefer mineral, non-greasy sunscreens, those with sensitive skin seeking a gentle formula, and travelers who want a spill-resistant, airport-friendly option. If you value reef-safe ingredients and practical touch-up capability, this translucent SPF 30 refill keeps your face protected without altering your look or routine.
