Harken Derm Mineral Sunscreen SPF 50 Travel Size — 80-Minute Water-Resistant, Reef-Safe with Botanical Antioxidants

Formulated by a practicing dermatologist, this zinc oxide and titanium dioxide mineral sunscreen creates a physical barrier to reflect UVA and UVB rays without relying on chemical filters. The lightweight, micronized minerals blend quickly and sit comfortably on skin, while four plant-derived antioxidants help combat environmental stressors. Packaged in recyclable sugarcane tubes, the travel-size option is designed for outdoor sports, water days, and everyday use when reliable, reef-safe protection matters.

How does Ultimate Shield stay on during water and sweat?

The formula includes film-forming and adhesive agents that bind the mineral particles to the skin surface, reducing wash-off from swimming or heavy perspiration. That engineered adherence supports up to 80 minutes of water resistance under standard testing conditions.

• Micronized zinc oxide and titanium dioxide for a stable, physical barrier
• Water-resistant formulation tested for durability in aquatic activity
• Non-greasy finish that helps minerals remain on the skin

Will this sunscreen feel heavy or leave a white cast?

Designed to minimize whiteness, the mineral pigments are finely milled so they disperse evenly for a more natural finish across many skin tones. The texture is lightweight and spreads smoothly, allowing application on the face and body without a chalky feel.

• Micronized mineral particles for reduced visibility on skin
• Sheer, fast-blending texture suitable for daily wear
• Non-comedogenic formulation recommended by dermatology professionals

What skin benefits come from the botanical antioxidant complex?

Beyond sun protection, the antioxidant blend helps neutralize free radicals created by UV exposure and environmental pollutants. These botanicals support skin hydration and resilience, helping keep skin comfortable during extended outdoor use.

• Four plant-derived antioxidants to counter oxidative stress
• Hydrating ingredients that help maintain skin moisture
• Formulation choices aimed at reducing irritation risk

Is this product reef-safe and sustainably packaged?

Yes — the sunscreen uses only mineral active ingredients, avoiding chemical UV absorbers that are restricted in some marine areas. The tube is made from recyclable sugarcane material to lower plastic use and environmental impact.

• Reef-safe mineral actives: zinc oxide and titanium dioxide
• Recyclable sugarcane tube for reduced plastic waste
• Developed with environmental awareness and performance in mind
