The 4D Approach
Skin · Structure · Movement · Personality
The 4D Approach is the diagnostic framework that underpins every aesthetic consultation at 23MD. Rather than treating a single feature in isolation, we read the face across four dimensions, and only then propose a plan.
- Skin. Quality, tone, texture, hydration, pigmentation.
- Structure. Bone, fat compartments and ligaments.
- Movement. Expression, muscle dynamics and resting tone.
- Personality. Who you are, and what looks like you.
