Brush On Block SPF 30 Mineral Powder Sunscreen - Sheer Daily

Our review of Brush On Block SPF 30 mineral powder sunscreen finds it best suited for people who want a lightweight, reapply-friendly mineral sunscreen they can use over makeup. The updated formula includes skin-supporting ingredients like niacinamide, hyaluronic acid and vitamin C, and its zinc oxide active delivers broad spectrum protection without chemical filters. The twist-open brush applicator makes on-the-go reapplication easy, which is the single biggest reason to choose this product if portability and a translucent finish matter.

Key Features

• Updated formula: Contains niacinamide, hyaluronic acid and vitamin C to help support skin hydration and tone while providing sun protection.
• Mineral active: Uses zinc oxide as the active ingredient, offering broad spectrum coverage without chemical sunscreen actives.
• Twist-open applicator: The brush design controls powder flow so you can pack it closed and apply only after twisting to open for less mess.
• Sheer finish: The translucent mineral powder goes on lightly and can be applied over makeup without noticeably changing skin tone.
• Portable reapplication: The compact powder applicator fits easily in purses or make-up bags for convenient touch-ups during the day.
• Cruelty-free and reef-friendly: Vegan formula without nano-sized particles and without oxybenzone or octinoxate, suitable for environmentally conscious users.

Who It's For

This sunscreen is ideal for people who need a convenient, non-chemical mineral sunscreen to reapply during daily activities, especially those who wear makeup and want a translucent, non-greasy finish. It also suits sensitive and oil-prone skin types because zinc oxide is a gentle, physical blocker and the formula avoids common chemical actives.

People who prefer a liquid or cream sunscreen for heavy water exposure, or those who need a precise SPF measurement for prolonged water sports, should consider other formats. Users who find powder applicators inconsistent may want to test a sample first, since some reviewers reported occasional difficulty getting powder to dispense.
