Trusted by patients who put safety first
Take Control of Your Aesthetic Journey
Tweak is the UK's Treatment Passport app for aesthetics. Track every treatment, product and practitioner in one secure place, and connect with verified medical aesthetic professionals you can trust.
Right now, the UK aesthetic industry is largely unregulated. "Anyone" can inject "anything" in people's faces. Patient safety, standards, and transparency should not be negotiable. That's why Tweak app was founded — by doctors, for patients.

FOR CLINICS
Be Found by the Right Patients
Tweak is the Treatment Passport app for aesthetics. We help verified medical aesthetic professionals get found by patients who are specifically looking for safety-conscious, qualified practitioners in their area.
Tweak partners with BAMAN and BCAM, giving members of both associations a practical way to help their patients identify verified professionals and keep a record of the treatments they've had.
“Right now, the UK aesthetics industry is largely unregulated. Patient safety, standards and transparency shouldn’t be negotiable. Every clinic on Tweak is verified before going live, so you’re never competing for attention alongside unregulated providers.”
Dr Kat Bennett, Founder, Tweak
How it works
1. Apply and verify. Share your lead practitioner’s name, registration number and proof of insurance.
Get set up. Verification and payment take five to ten minutes.
3. Go live. Once you’re verified and payment is confirmed, your profile is live within 48 hours.
Why clinics join Tweak
– No commission on bookings, and no limit on how many patients you can take through the platform.
– A profile built on trust. Patients can see you’re genuinely verified, not competing alongside unregulated providers.
– Patients who use Tweak’s Treatment Passport to track their treatment history tend to be engaged and considered, not price-shopping around.
Pricing
£29 a month, or £250 a year. No hidden fees.
