PRODUCT DETAILS

Hello, daily defense. Biome Double Defense Sunscreen gives you broad-spectrum SPF50+ PA++++ protection and helps guard against sun exposure linked to premature visible aging and damage.

Rather than feeling like a heavy final layer, it has a lightweight water-essence texture that absorbs easily. The finish is smooth and comfortable, without white cast or stickiness, and suits all skin tones.

Skincare support comes along for the ride. The Special Biome Blend helps maintain skin balance and support the barrier, while kombucha fermented extract and Galactomyces Ferment Filtrate support moisture retention and hydration. Cranberry-derived peptides help support elasticity and a firmer-looking complexion. The formula also contains functional ingredients intended to support a clear, resilient appearance.

It layers easily without residue or heaviness, helping your final skincare step feel simple rather than crowded. You get daily sun care with a light touch, plus thoughtful support for moisture, the skin barrier and visible firmness.
