Skin diagnosis, explained

Before we choose a treatment, we work out where your concern begins. Here is how imaging, examination and our 8-layer model come together to shape your plan.

Why diagnosis comes before treatment

Many skin concerns look similar on the surface but start in different places. A brown patch may be pigment close to the surface or pigment spread more deeply. Sagging along the jaw may come from loosening skin, descending fat, weakened support tissue or changes in the bone beneath. If the wrong layer is treated, even an excellent device can give a disappointing result. That is why our rule is simple: decide the depth first, then the device.

The 8-layer Skin Architecture model

We think of the face as eight layers, from the surface inwards:

  1. Epidermis — the outer surface and barrier; home to much surface pigment, texture and dullness.
  2. Upper dermis — just beneath, where fine texture, early fine lines and some pigment and redness sit.
  3. Full-thickness dermis — the main collagen layer that gives skin its firmness.
  4. Lower dermis — deeper collagen that supports elasticity and structure.
  5. Subcutaneous fat — fat compartments that give fullness and can descend with age.
  6. Fascia — the supportive layer that helps hold tissue in place.
  7. Muscle — responsible for expression lines and some contour, such as a square jaw.
  8. Bone — the foundation; changes here affect everything above.

Ageing tends to work from the inside out: bone changes, deep fat shifts, support tissue weakens and fat descends, leading to hollowing and sagging. Pigment and texture problems, on the other hand, usually begin near the surface. Mapping your concern to the right layer guides every choice that follows.

Mark-Vu imaging

Mark-Vu imaging analyses your skin for pores, pigment, wrinkles, redness and oil–moisture balance. It helps reveal things that are hard to judge by eye, such as pigment that is not yet obvious, uneven redness or areas of dehydration. The images also create a baseline, so future visits can be compared with your starting point rather than relying on memory.

The doctor's examination

Imaging informs the diagnosis; it does not replace it. A director sees you from the first consultation and examines your skin and facial structure directly — how skin moves, where volume has changed, how firm the tissue feels and how your face looks when you talk and smile. The doctor also asks about your history: sun exposure, hormones, previous treatments, sensitivity and lifestyle. For medical concerns such as rosacea, acne or hair thinning, the doctor examines you first before any treatment is suggested. For moles, suspicious lesions are assessed and referred for proper medical evaluation where needed.

From diagnosis to plan

Once the layer is clear, the doctor chooses the approach. A few examples:

  • Surface pigment or melasma: barrier care first, then options such as PICOALEX , BRIGHTONE or Nobleen toning .
  • Texture, pores or acne scars: options such as Potenza or CO2 laser, chosen by depth.
  • Loss of firmness: energy lifting matched to depth — for example 1.5, 3.0 or 4.5 mm HIFU, or RF through the dermis.
  • Volume loss: a dual-plane approach — structural support near the bone first, then the fat layer, with muscle last.

Your Skin Library

Your diagnosis and every treatment are recorded in your Skin Library, our digital treatment record. When you return to Seoul or message us from home, the team can see what was found, what was done and how your skin has changed. Results vary from person to person, and careful records help the plan evolve sensibly over time.

Getting the most from your diagnosis

A little preparation helps the analysis reflect your skin as it really is.

  • Come with clean skin if you can. Heavy make-up or tinted sunscreen can hide redness and pigment from both the camera and the doctor.
  • Bring your history. Note previous lasers, injectables or threads and roughly when you had them, plus any medicines or skincare actives you use.
  • Say what bothers you most. Imaging may show several things; your priorities help the doctor decide where to start.
  • Ask to see your images. Looking at the results together makes it easier to understand why a certain layer and approach are suggested.

Questions about skin diagnosis

  • Is the Mark-Vu analysis painful?

    No. It is a non-invasive imaging process. You simply sit in front of the device while images of your skin are taken and analysed.

  • Can you diagnose my skin from photos on WhatsApp?

    Photos help the team suggest likely options and prepare a quote, but they cannot replace an in-person examination. The final plan is made after a director sees you.

  • Why does the layer matter so much?

    Different devices and injectables work at different depths. Matching the treatment to the layer where your concern starts makes it more likely the plan addresses the real cause.

  • Will I see my analysis results?

    Yes. The doctor will go through your images with you and explain what they show and how they shape your plan.
