BRAND FILM
Precise data first, then beauty made for you alone
For a long time, judgments about beauty rested on instinct alone. TheiA Clinic works the other way round: evidence first, analysis first. That is the standard we bring to seoul dermatology.
DERMA CODE · AI SKIN ANALYSIS
Derma Code (AI skin analysis)
Derma Code is an AI skin-analysis program developed in-house by the doctors at TheiA Clinic. It records your skin condition as measured values rather than an eyeball estimate, and those values become the reference material for your consultation. Reading the results and deciding on any treatment is always done by a doctor, in person.
“An AI skin-analysis program developed by doctors themselves — precise data first, then beauty made for you alone.”
STEP 02
AI CURATION
Based on those values, candidate treatment combinations are listed for the consultation.
STEP 03
AI REPORT
The analysis and consultation are compiled into a report you can compare on your next visit.
※ Derma Code is an analysis aid for consultation. Diagnosis and treatment decisions are made by a doctor.
SIGNATURE
Three signature programs
These are the three programs TheiA Clinic Gangnam presents together with a Derma Code analysis. Every procedure follows a prior consultation and a doctor's judgement, and whether it applies to you — and to what extent — depends on your individual skin condition.
- Ultherapy
- ulthera korea
- AI skin analysis
Derma Code + Ultherapy
Micro-focused ultrasound (MFU) device
After Derma Code records your skin condition, we discuss whether and where Ultherapy applies. Ultherapy is an ultrasound-based lifting device held at this clinic — one reason patients searching for ulthera korea come to Gangnam.
- Titanium
- RF lifting
- AI skin analysis
Derma Code + Titanium Lifting
Radio-frequency (RF) device
Using the Derma Code results as a reference, we discuss the scope of Titanium Lifting. Titanium is a radio-frequency device held at this clinic.
- Rejuran
- korean skincare
- AI skin analysis
Derma Code + Rejuran
Injectable treatment
With your Derma Code reading in hand, we discuss whether Rejuran is appropriate — a frequent question from visitors exploring korean skincare. Eligibility and the number of sessions follow the doctor's judgement.
※ Outcomes vary with individual skin condition and lifestyle, and side effects are possible. Please consult a doctor thoroughly before any procedure.
