Medicube PDRN Pink Peptide Serum + COSRX Hyaluronic Acid Intensive Cream + COSRX Retinol 0.5

You can successfully use the Medicube PDRN Pink Peptide Serum, COSRX Hyaluronic Acid Intensive Cream, and COSRX The Retinol 0.5 Oil together, but because 0.5% retinol is a high-strength, potent active, you must alternate nights or use the sandwich method to
protect your skin barrier.

Morning Routine (A.M.)

Cleanse: Wash with a gentle, hydrating cleanser.

Hydrate & Glow: Apply the Medicube PDRN Pink Peptide Serum on slightly damp skin to leverage its peptides, niacinamide, and PDRN for radiance and elasticity.

Moisturize: Follow with the COSRX Hyaluronic Acid Intensive Cream to lock in multi-depth moisture.

Protect: Finish with a broad-spectrum sunscreen of SPF 30 or higher (mandatory when using retinoids)

Evening Routine (P.M.) — Non-Retinol / Recovery Nights

Cleanse: Wash face and pat completely dry.

Repair: Apply the Medicube PDRN Pink Peptide Serum to support skin recovery and barrier health. Seal: Apply a generous layer of the COSRX Hyaluronic Acid Intensive Cream.

Evening Routine (P.M.) — Retinol Nights (2 to 3 times a week max to start)

Cleanse & Dry:  Wash face and ensure skin is completely dry to prevent excess penetration and irritation.

The Buffer (Sandwich Method): Apply a thin layer of the COSRX Hyaluronic Acid Intensive Cream first if your skin is sensitive.

Active: Apply 1-2 drops of the COSRX The Retinol 0.5 Oil, gently pressing it over your face while avoiding the eye and lip areas.

Seal: Finish with another light layer of the COSRX Hyaluronic Acid Intensive Cream.
