Interviews
Real experiences from medical professionals and skincare specialists
I cut the prescriptions, recommended a skincare product — and that became word of mouth.
Most acne patients leave with an antibiotic prescription after extraction. But many of them resist medication. Since placing La Théorie in our clinic, I've been able to give patients a real at-home routine to maintain their results. Fewer flare-ups meant fewer complaints — and satisfied patients started bringing in friends. Recommending a skincare product instead of another prescription actually built more trust. New patient referrals increased, return visits went up, and we now have a far more stable revenue structure than procedure-only treatment ever gave us.

It turned out the skincare product was driving more return visits than the treatments.
No matter how well a treatment goes in the salon, if a client goes home and uses something irritating, they're back to square one. I came across La Théorie on YouTube — a skincare line built specifically for troubled skin — and decided to try it. Once clients had a proper home routine, the results from our treatments lasted much longer. That naturally led to more return visits and referrals. Now it's the first product I explain to every new client.

La Théorie began its journey through dermatology clinics and medical aesthetic salons — spaces where efficacy is non-negotiable and trust is everything. Recommended by doctors, chosen by patients, our products quietly became a staple in over 200 clinics across Seoul and Busan.
We have recently expanded into Chicor, one of Korea’s leading premium beauty retailers, marking our first step beyond the clinic and into the broader consumer market. More patients. More skin. More stories.
