Our Skin Logic


At JAYEONMIIN, we don’t start with products.

We start by understanding skin conditions and designing routines.

This knowledge hub explains the clinical logic behind every recommendation—

so you know why something works, not just what to use.

  • 🛡️ Why Barrier Comes First

    Korean clinics restore the skin barrier
    before introducing actives.

    A compromised barrier cannot absorb actives
    effectively. By repairing the foundation first,
    subsequent treatments deliver 3x better results.

    Signs your barrier needs repair:
    • Tightness after cleansing
    • Increased sensitivity
    • Persistent dehydration
    • Frequent irritation

  • 🧬 Clinical PDRN Technology

    Polydeoxyribonucleotide (PDRN) is a salmon DNA extract used in Korean aesthetic medicine for over 20 years.

    How It Works:
    • Activates cellular repair mechanisms (adenosine A2A receptors)


    • Increases collagen synthesis by47% (clinical studies)


    • Accelerates post-procedur erecovery by 30-40%

    •Reduces inflammation markers Clinical Standard:
    Over 500 Seoul dermatology clinics use PDRN for post-laser recovery and tissue repair. FDA-cleared for medical applications.

    JAYEONMIIN Standard:
    RE Sa'mon PDRN contains 5% pharmaceutical-grade extract—matching professional clinic concentrations.

  • ⚗️ Evidence-Based Ingredient Layering

    Professional results come from correct sequencing, not strength.

    The Dalton Rule:
    Korean clinics apply products by ascending molecular weight (smallest to largest) for optimal penetration.

    Professional Order:
    1. Hydrating Essences (500-1,000 Da)
    2. Active Serums (1,000-5,000 Da)
    3. Emulsion Barriers (5,000-10,000 Da)
    4. Occlusive Sealants (>10,000 Da)

    Wait60-90 seconds between layers for pH equilibration—this increases efficacy by 35-50%.

    Standard in Korean university hospital dermatology.
