Five Ingredients. That's it.
01
Non-Nano Zinc Oxide Mineral
+

Active UV filter

The only active ingredient in Swellies. UVB & UVA protection from one ingredient.

02
Coco Caprylate/Caprate Plant-derived ester
+

Texture and feel

Replaces the synthetic silicones found in most sunscreens with a biodegradable alternative that gives the same dry, silky finish without the environmental cost. Absorbs fast, leaves no greasy residue, and creates a smooth, comfortable skin feel.

03
Dextrin Palmitate Cassava-derived
+

Gel texture and finish

Converts the formula from a liquid into a lightweight breathable gel that slips across your skin with a velvety feel at the point of application.

04
Polyhydroxystearic Acid Castor oil-derived
+

Dispersion and blendability

Disperses Zinc Oxide evenly throughout the formula, which is a large part of why Swellies blends in and doesn't leave a noticeable white film on your face.

05
Iron Oxides Mineral
+

White cast elimination and blue light protection

Neutralize the white cast that comes with zinc oxide by adding a very small amount of natural pigment, just enough to give a sheer, skin-toned finish.

Our Story

Sunscreen's counterculture.

I spent years looking for a mineral sunscreen that didn't feel like a compromise. Anything that felt good was loaded with hormone disruptors and silicones. Anything with clean ingredients felt like a thick paste I'd dread putting on, let alone reapplying. Couldn't find one that solved both problems.

So we built it. Five ingredients. Every one of them solves a problem that made me hate sunscreen. The formula is founder-developed and made in-house. No contract manufacturer, no mystery actives, no filler.

We're not a clean beauty marketing company packaging up someone else's formula with a better label. We're not a surf brand trying to convince you we're cool. We don't have 12 SKUs and a lifestyle campaign. We have one product, we built it ourselves, and it works.
