Affiliate disclosure

Luma Index is funded by affiliate commissions. When you click some retailer links and buy something, the retailer may pay us a commission. You don't pay any more.

Commissions never decide which masks we list, the order they appear in, or what information we show. Masks without an affiliate programme are listed in exactly the same way. Commercial links are marked with rel="sponsored", and the retailer's name is always shown on the button.

We use Cloudflare Web Analytics, which doesn't use cookies, to count visits and clicks to retailers.
