Supergoop! (Re)setting Powder

A zinc oxide powder for touching up sun protection over makeup. Useful for reapplication — and not adequate as your only sunscreen.
At a Glance
Mixed

A powder sunscreen like this does not deliver the SPF on the label in real use. The SPF on any sunscreen is measured at a thick, even layer. Studies of powder sunscreens find people apply about a tenth of that, which is well short of the labeled SPF. So the label says SPF 35, but the way you brush it on will not deliver that.

Where a powder shines is reapplication. Almost nobody reapplies sunscreen, mostly because of makeup, and a powder brushes on over a finished face without wrecking it. A layer of this at midday beats the nothing most people apply.

Start with a proper sunscreen in the morning, then use this to top up. It is talc-free and fragrance-free, with ceramides to offset the dry feel powders can have.

How it works

Reapplication is the biggest unsolved problem in sun protection. Almost nobody reapplies sunscreen, and the main reason is makeup — you are not going to rub lotion over a finished face at 1 p.m.

A powder solves that, and this one solves it well. It brushes on over makeup, cuts shine, and adds real zinc oxide. A layer of this at midday is much better than the nothing that most people apply.

Talc-free and fragrance-free, with ceramides added to offset the drying feel powders usually have.

Used for its actual purpose — a top-up over sunscreen you already applied — it is a genuinely useful product.

Everyday habits

How to use it
  • When: Over a sunscreen you already applied, as a midday top-up.How much: Powders go on thin, so you will not reach the label SPF from powder alone. Brush on an even, visible layer. Where: Face, focusing on areas that get direct sun. Reapply: Every 2 hours outdoors, and after sweating or swimming. Best use: Treat it as reapplication over a base sunscreen, not as your first layer.
Who should be careful+

Do not use this as your only sunscreen. This is the important part. The SPF number on any sunscreen is measured at a thickness of 2 mg/cm². Studies of how people actually apply powder sunscreens find they get on roughly a tenth of that — nowhere near enough to deliver the SPF on the label.

The label says SPF 35. The reality of how you'll brush it on does not. Apply a real sunscreen in the morning. Use this to top up.

It is small and expensive — 0.15 oz for around $30–35. If you tried to use it for full-face coverage it would cost a fortune and still under-deliver.

The translucent shade can look chalky on deeper skin tones.
