How We Work

    The 23MD Method.

    A four-part methodology — diagnostic, structural, sequential and systemic — that governs every consultation, plan and treatment at 23MD.

    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.

    Dermal Architecture

    Structure · Contouring · Volumising

    Dermal Architecture is our injectable methodology. We treat the face as a layered structure — bone, deep fat, superficial fat, skin — and intervene at the level the concern actually lives in.

    • Structure. Reinstating the underlying scaffolding where bone resorption or laxity has shifted proportion.
    • Contouring. Shaping the perimeter — jawline, chin, temples, brow. Subtractive thinking.
    • Volumising. Replacing what time has taken, only where loss is genuinely the cause.

    Combining Treatments

    System · Structure · Surface

    When more than one treatment is needed, the order matters. We work from the inside out — internal foundations first, structural support second, surface finishing last — so each stage supports the next.

    • System. Internal foundations first — hormones, metabolism, sleep, inflammation.
    • Structure. Then the architecture — bone-level support, deep volume, ligament-aware contouring.
    • Surface. Finally the surface — regenerative facials, boosters, polynucleotides, devices.

    360 Longevity

    Hormonal · Metabolic · Regenerative · Lifestyle

    360 Longevity is the wellness arm of the 23MD method. It maps healthspan across four interlocking systems, and treats them as one continuous physiology — not four separate appointments.

    • Hormonal. Comprehensive panels and bioidentical, physician-led replacement where indicated.
    • Metabolic. Glucose, insulin, lipids, body composition.
    • Regenerative. IV nutrients, sleep architecture, cellular repair.
    • Lifestyle. Movement, nutrition and stress load, written into the plan.

    Begin with a doctor-led consultation.

    Every 23MD patient starts with The Foundation Reset — bloods, 4D facial assessment, 360 Longevity consultation, and a written treatment plan within 24 hours.
