Why we made it

We’re solving the daily SPF dilemma. This formula pairs mineral-based defense with the comfort of your favorite moisturizer so you don’t have to choose between protection and great skin. One step, total coverage.

Why Your Skin Will Love It

  • Dual mineral actives create a seamless shield
  • Hyaluronic acid and squalane deliver lasting hydration from AM to PM
  • Barrier-friendly ingredients support smooth, healthy skin over time

How to use

Apply to clean, dry skin as the last step in your morning routine. Use a generous amount 15 minutes before sun exposure. Reapply every two hours, or after swimming or sweating. Rub in well (mineral-based SPF takes a moment to sink in). Lightweight and breathable on its own, or easy to wear under whatever else you use.

Doesn’t sweat off on the subway!

I needed something that could survive a humid NYC summer and still look okay at work.... this is it. It is so sheer and hydrating, stays put all day!!

Best mineral SPF I’ve tried

So many claim to be invisible and aren’t. This product actually lives up to it and feels so nice on skin too! I've been reapplying it for the first time in my life lol

My new moisturizer

This product has become my 2 in 1 moisturizer and SPF. As a guy who is not a fan of a skincare routine and has darker skin, this is my ideal product.

My makeup sits perfectly on top

I use this right before I put on my makeup, and it’s amazing under the foundation I wear. Honestly feels more like skincare than SPF.

Part of my new every day routine!

This product is awesome and will be part of my daily routine from now on. Absorbs into the skin so easy and feels so fresh. Plus the packaging and branding is so cool. Love my new daily SPF product!
