Proton Health

Proton Health is a London-based healthcare technology company that develops Symphony, an AI-driven dermatology platform for people living with chronic skin conditions including eczema, acne, rosacea, psoriasis, hyperpigmentation, redness and dryness. The product is built around identifying the causes of flares rather than treating symptoms alone: users complete a "360° scan" capturing photos, symptoms, lifestyle, mental health, diet and product use, and Symphony compares that profile against large volumes of dermatology data to surface candidate triggers such as stress, sleep, weather, skincare products and foods.

The platform then produces a personalized plan spanning skincare, diet, lifestyle and mental wellbeing. Additional modules include analysis of skincare product ingredients against a user's profile, more than 50 mental wellbeing sessions addressing issues such as social anxiety, the itch-scratch cycle and self-esteem, and condition-specific educational lessons. For users seeking deeper clinical investigation, Symphony offers dermatology consultations, gut and skin microbiome testing and full lab panels.

A private-market data profile classifies Proton Health under telemedicine, patient engagement and medical AI, and describes Symphony as supporting both patients and dermatologists.

Business model

Proton Health operates a subscription-based digital health service delivered directly to consumers through the Symphony app, offering a free initial assessment followed by personalized plans, educational lessons and mental wellbeing content. Paid clinical add-ons include dermatology consultations, gut and skin microbiome testing and laboratory panels. A third-party private-market profile characterizes the company as B2B with subscription SaaS and freemium customer profiles, and records the addition of a pharmaceutical company as a customer.

Freemium and subscription access to the Symphony app, with paid clinical services such as dermatology consultations, microbiome testing and lab panels available as upgrades.

Traction

The company reports more than 4,500 users of Symphony and a 4.9 out of 5 average rating, and states that 92% of members identify at least one new trigger within seven days. Outcome claims on quality of life, skin concern and mental wellbeing improvement are attributed to an internal Proton Health outcomes dataset covering 2021-24, measured as average change at 90 days. A private-market data provider reported a 76% month-over-month increase in monthly visitors in August 2026.
