ComfiSkin vs Thea
Thea is an AI skincare app that charges a subscription, sells products in the app and offers prescriptions through telehealth. ComfiSkin sells nothing, charges nothing and never needs your face.
Where Thea makes money
ComfiSkin: $0, nothing to sell
From Thea’s App Store listing and Fitt InsiderThe short answer
Thea costs $19.99 a month or $99.99 a year after a trial that renews automatically. It also sells products in the app and offers telehealth prescriptions, so the advice, the shop and the pharmacy are one business. Its CEO admitted it “wasn’t clear to people” that some promoters were its ambassadors, it stores your face photos on its servers, and its terms force disputes into private arbitration.
What that means: an app that earns three ways from your skin worries, marketed in ways that weren’t always clear. For prescriptions, see your own doctor. For choosing products, ComfiSkin is free and sells nothing.

Advice, shop and pharmacy in one
Fitt Insider described Thea as “combining diagnostics and commerce”, with a shoppable database and prescriptions including “microdosed acutane” and the hair-loss drug finasteride. It raised $4 million from investors in 2026.2 So the same company that tells you what’s wrong with your skin earns from the subscription, from the products it recommends and from the prescriptions it arranges.
That’s a lot of reasons to find a problem. ComfiSkin earns nothing from your skin worries. It helps you understand the products you have and are considering, and if you need medication, it tells you to see a doctor.
What that means for you: when one app diagnoses, sells and prescribes, every step has a reason to say you need more. Prescriptions belong with your own doctor.
Marketing that wasn’t clearly marketing
Replying publicly to an App Store review, Thea’s CEO acknowledged that “it wasn’t clear to people that this was a team of ambassadors”, referring to people promoting the app online.1 Promotion that doesn’t look like promotion is exactly what makes social media skincare advice hard to trust.
ComfiSkin doesn’t pay anyone to talk about it. If you hear about it, it’s because someone found it useful.
What that means for you: some of the enthusiasm you saw for Thea online may have been organised by Thea.
Your photos, on their servers and behind a paywall
Thea’s privacy policy says it stores your face photos on its servers “along with the photo itself”, and its App Store label lists photos, sensitive info and location as linked to you.3,1 One reviewer complained that “now you have to PAY to view all your photos” of their progress.5 Its terms also require binding arbitration and waive class actions.4
ComfiSkin never asks for your face. If you keep progress photos in its journal, they stay on your phone, and you never pay to see them.
What that means for you: your progress photos live on Thea’s servers, and seeing them can cost you. In ComfiSkin, they’re yours, on your phone.
