Market Opportunity
La Théorie sits at the intersection of two fast-growing waves.
K-Beauty and Clinical Derma are both outpacing the general skincare market. La Théorie carries both — the cultural momentum of K-Beauty and the credibility of dermatology science.
The fastest-growing sector in skincare
Clinical Derma is growing at 2.6× the rate of general skincare — and La Théorie is built for exactly this market.

The Science
We focused on "taking out."
“Anyone can add ingredients that seem good. But La Théorie is a brand that knows what shouldn’t be included.”
For persistent skin issues — adult acne, folliculitis, dermatitis — what matters most is reducing adverse reactions caused by excessive formulation. We eliminated fatty acids, the hidden trigger behind most chronic skin conditions.
Peer-Reviewed Research

“Skin fungi feed on cosmetic ingredients.”
Malassezia, the fungus responsible for folliculitis and fungal acne, proliferates when fed fatty acids commonly found in skincare. La Théorie is the only brand that systematically removes these triggers from its entire product line.
Sales Achievement
300,000+ units sold to 50,000+ patients. Repurchase was the engine.
Our hero cream alone has driven over 300,000 cumulative units sold as of 2025 — powered by repeat purchases from patients who experienced real results. Not by reach. By results.
Cumulative units sold · Single SKU
Clinic First
We started where skin conditions are treated — not sold.
La Théorie grew exclusively through dermatology clinics. Over 200 clinics across Seoul and Busan have carried our products — recommended by physicians to real patients with real skin conditions.
