Knowledge
Practice guides that actually get specific.
We don't write SEO-volume posts. Each article answers a question practices have asked us in consultations, with GOÄ codes, device specs and experience from real pilot practices.

Introducing a skin-analysis IGeL service in your practice, from consent to billing
3D skin analysis is a classic German IGeL (Individuelle Gesundheitsleistung). We walk through the steps the German federal medical organisations (KBV and BÄK) define for a clean IGeL introduction, from patient briefing through the written agreement to billing, and show where Dermalia fits into each step.

Skin analysis and skin cancer prevention, why 3D topography is not a screening substitute
A cosmetic 3D skin analysis detects UV pigment, wrinkles and pores. It does not detect melanoma and does not replace dermatoscopy or statutory skin-cancer screening. This article makes the methodological limit explicit, describes where the method legitimately complements the prevention chain, and names the regulatory background.

MDR classification for skin-analysis software, what MDCG 2019-11 means for the practice
In June 2025 the Medical Device Coordination Group (MDCG) published MDCG 2019-11 Rev.1 and tightened the rules on software classification under MDR and IVDR. We walk through what this concretely means for software around skin-analysis devices, where the class boundaries sit and what practices should check before deploying.

Patient consent for 3D skin analysis, what Art. 9 GDPR concretely requires
Biometric facial scans are special categories of personal data under Art. 9 GDPR. We walk through which legal bases are available, what the consent must contain, and where the most important traps for the dermatology practice sit. Not a template, a requirements checklist.

Fitzpatrick skin type and Individual Typology Angle, why laser practices need both
Fitzpatrick skin type I-VI has been the standard for laser-energy selection for decades. The Individual Typology Angle (ITA°) provides an objective device-based complement in the CIELAB colour space. We walk through what each scale delivers, where they differ, and how a practice uses them together for safe laser preparation.

Skin analysis for rosacea, what erythema mapping and telangiectasia findings deliver
Rosacea is a chronic, relapsing-remitting indication whose course is hard to document in words. We show how 3D skin analysis with the redness spectrum helps with erythema and telangiectasia, what role IPL and pulsed-dye laser play in the current therapy mix, and where the limits for advertising and diagnostic claims sit.

Skin analysis for pigment disorders and melasma, separating UV from visible pigment
Melasma, solar lentigo and post-inflammatory hyperpigmentation look clinically similar but sit at different depths in the skin. We show what the 3D skin analysis contributes to the differential workup, how the Modified MASI score can be used as a longitudinal metric, and where the limits for advertising sit.

Skin analysis in the acne consultation, what the UV capture actually shows
Porphyrins, pore counts and longitudinal documentation during isotretinoin therapy. We walk through the typical acne report workflow: what a 3D skin analysis shows, what it does not, and where the limits for diagnosis and advertising sit.

Skin analysis in the anti-aging practice, what patients should actually see
A skin analysis is not mandatory in the aesthetic consultation, but when it is used, the format decides patient retention. We show which report building blocks really carry weight in an anti-aging practice and where device marketing misses the point.

Before/after with skin analysis, what makes treatment documentation reliable
A before photo and an after photo are not enough. Anyone documenting filler, botox, microneedling or laser therapies needs reproducible captures, normalised positioning and comparable score values. We walk through the five requirements a skin analysis must meet for honest before/after.

GDPR for medical image analysis, a practice checklist
When you use 3D skin analysis in your practice, you are processing health data under Art. 9 GDPR. What does that mean concretely? We walk through the eight points a practice must clear before the first real patient scan, legal basis, data processing agreement, information sheet, retention and the third-country transfer problem.

Billing skin analysis, which GOÄ code applies when
Digital 3D skin analysis has no native code in the German fee schedule (GOÄ). We walk through the three codes practices actually use today, including multipliers, analogous billing per § 6 (2), and what you must declare as a self-pay service for statutory-insured patients.

Observ vs Isemeco, when each device makes sense
Sylton Observ 520x is a compact multispectral device used by many cosmetic clinics and some dermatology practices. Isemeco D8/D9 are 3D topography systems from the medical segment. We show where the two overlap and where they part ways.

VISIA vs Isemeco, an honest comparison
Canfield VISIA has been the most common skin analysis system in dermatology practices for over twenty years. Isemeco D8/D9 is the younger 3D generation. We compare both devices on the points that actually decide a purchase: methodology, report depth, cloud hosting, service and price.

3D skin analysis vs 2D multispectral, where the difference really lies
VISIA, Antera 3D, Observ, Isemeco, imaging methods in skin analysis differ in more than marketing. We compare 2D multispectral (VISIA) and 3D topography (Antera, Isemeco) along the four report areas where the methods diverge in practice.
