ComfiSkin vs SkinSignal

The short answer

SkinSignal is free and has no ads, but it names no company or address, its only contact is a Gmail address, its terms say they’re governed by the laws of the Russian Federation, and its privacy policy, titled “Privacy Ploicy”, hasn’t been updated since October 2022. And like any ingredient website, it compares lists without knowing your skin.

What that means: if something goes wrong, there’s no one clearly accountable, and you still have to work out whether a product suits you. ComfiSkin is free too, answers for your skin, and keeps your notes on your phone.

Nobody to hold to account

SkinSignal’s terms define the company simply as “Skinsignal” and say “Country” refers to the Russian Federation, whose laws govern the terms. There’s no legal entity, no address, and the only contact on the site is a Gmail address.1 Its privacy policy is headed “Privacy Ploicy” and dated 25 October 2022, and says it uses Google Analytics and Amazon Web Services.2

Anonymous isn’t the same as malicious, and the site carries no ads. But when you can’t tell who runs a service or where to complain, you have nowhere to turn if something goes wrong. ComfiSkin publishes its privacy policy and terms, and keeps your skin notes on your phone rather than on anyone’s servers.

What that means for you: if you have a problem with SkinSignal, there’s no clear company to take it to.

A comparison of lists, not an answer for you

Like other ingredient websites, SkinSignal compares lists and explains ingredients. It doesn’t know your skin type, your concerns, the ingredients you avoid or what you already own. ComfiSkin does, and puts it all together into one clear answer, in the shop, from a scan of the label.

What that means for you: you still have to work out on your own whether to buy the product.

What to do if you use SkinSignal

  1. Don’t share personal details with a site that won’t say who runs it.
  2. Use comparisons as a starting point, not a verdict on your skin.
  3. Check products against your skin in ComfiSkin, free, with your notes kept on your phone.
