Results vary by skin type and concern, but most users notice:

Week 1-2: Improved hydration and skin texture

Week 3-4: Visible brightness and reduced redness

Week 6-8: Significant improvement in fine lines, pore appearance, and overall skin clarity

For best results, we recommend following our 8-12 week protocols. Consistency is key—Korean dermatology focuses on gradual, sustainable improvement rather than instant transformation.

PDRN (Polydeoxyribonucleotide) is a salmon-derived DNA extract widely used in Korean dermatology clinics for skin regeneration.

Clinically proven benefits:

• Accelerates wound healing and post-procedure recovery
• Stimulates collagen production
• Reduces inflammation and improves skin barrier function
• FDA-approved and used in Korean clinics for 15+ years

Our PDRN products (EXO SKIN, DOUBLE PN) contain the same clinical-grade concentration used in professional treatments—adapted for safe home use.

A.

Yes. All JAYEONMIIN products are:

• Dermatologically tested for sensitive skin
• Free from parabens, artificial fragrance, alcohol
• pH-balanced (4.5-6.0) to support skin barrier
• Formulated for post-treatment and weakened skin conditions

However, skin response varies. We recommend:

• Patch test on inner arm for 24 hours
• Start with lower-concentration products
• Follow professional usage guidance included with each product

If you have active eczema, rosacea, or are under dermatological treatment, consult your doctor before use.

A.

Yes! JAYEONMIIN products are designed to integrate seamlessly.

Layering order (thinnest to thickest):

1. Cleanser
2. JAYEONMIIN Skin Booster (watery texture)
3. Your existing serums/treatments
4. JAYEONMIIN Cream or H₂ Moisture Drops
5. Sunscreen (AM only)

Avoid mixing with:

• High-concentration retinol (use on alternate nights)
• Strong AHA/BHA exfoliants (wait 10 minutes between)

Our products enhance absorption of other actives—many customers report their existing products work better after adding JAYEONMIIN.

A.

Regular serums: Focus on surface hydration and single ingredients

Korean skin boosters: Clinic-inspired formulations that:

• Deliver actives deeper into skin layers
• Support structural improvement (collagen, elastin, barrier)
• Use synergistic ingredient combinations (not just one "hero")
• Designed for targeted skin conditioning, not daily maintenance

Think of it this way:

Serums = Daily vitamins

Skin Boosters = Targeted medical-grade supplements
