High mineral protection in a sheer, creamy lotion.

You want strong protection every single day in a formula that goes on sheer, feels creamy and gives your makeup a smooth base.

This lotion gives you broad spectrum SPF 70 from 10% zinc oxide and 3.6% titanium dioxide, with no shaking needed. It blends into a sheer, soft finish that works on its own or as a primer under makeup, and it stays water resistant for 80 minutes. Niacinamide, squalane and panthenol keep skin comfortable, and skinbetter makes it without fragrance.

Who It Is For

All skin types who want high, everyday mineral protection that doubles as a primer.

Not Acne Safe

What You Will See, and When

The sheer, smooth finish is there the moment it goes on. Water resistance lasts 80 minutes of swimming or sweating, and then it is time to reapply.

How to Use

Every morning, whatever the weather and whether or not you leave the house, warm two finger lengths between your fingertips and smooth it over face and neck as your last skincare step, taking it down onto your chest too. Reapply at least every two hours, after 80 minutes of swimming or sweating and straight after towel drying, indoors and by a window too, because the film wears off. Tie it to washing your hands, and keep one by the sink and one in your bag.

The Science

The SPF number measures UVB, the light that burns. Broad spectrum means UVA is covered too, and UVA is the one that stays steady all year, passes through cloud and window glass, and reaches the depth where collagen sits. Zinc oxide and titanium dioxide are mineral filters that absorb and scatter ultraviolet light, and zinc oxide in particular covers the long UVA wavelengths and stays stable in sunlight.

SPF is measured in the lab at 2 mg of sunscreen per square centimeter of skin. In a study of real application, using half that amount brought the SPF down to roughly its square root, and a quarter of it brought it down to roughly its fourth root. Protection drops faster than the amount you skip, which is why the amount matters as much as the number. Reapplication matters for the same reason: the film wears off with time, touch and sweat, whatever the weather.

Questions

Where does it go in my routine?Last, every morning, after moisturizer and eye cream. Makeup can go straight on top.
Do I need it on a grey Seattle day?Yes, and on every other day too. UVA stays fairly steady through the seasons and passes through cloud and window glass, so sunscreen goes on every morning whether or not you go outside.
Does the SPF in my foundation count?Not toward this. SPF does not add up across products, so SPF in makeup is a bonus, never the plan.
Can I wear a tinted sunscreen with it?Yes. A tinted or powder SPF goes over this one as a top up, never in place of it.

Why a Routine Made for You Works Better

General advice is written for everyone, so it has to assume nothing about you. It can tell you what is safe. It cannot tell you what will work for your skin.

Skin changes when it is challenged just enough, then given time to recover and adapt. That amount is different for every person, and it moves as your skin gets stronger. Ask too much and your skin spends its energy recovering instead of improving. Ask too little and nothing changes. Finding that point for you, and moving it at the right time, is where results come from.

Where that point sits depends on:

  • Your skin: its history, how it reacts, and what it is doing today
  • Your health: hormones, medications, pregnancy and any condition that changes how skin behaves
  • Your lifestyle: sleep, stress, diet, sun, exercise and climate
  • Your routine: what you use now, and what has and has not worked before
  • Your goals: what you most want to change
  • Your expectations and timeline: how soon you want to see change, and what is realistic for your skin
  • Your consistency: how much time and how many steps you will keep up with, because the best routine is the one you actually do
  • Your treatments: what you have had and what you have planned

A skin therapist weighs all of this, builds a routine you can keep, and adjusts it as your skin responds. That is why we guarantee our products when they are part of a routine designed by one of our skin therapists. If you have been reading general advice, bring your questions. We will help you sort out what applies to you and what does not.
