A Korean retinol serum from Medicube — HPR+5 Retinol Complex at 1% concentration, meaning multiple forms of retinoid work at different depths and speeds simultaneously. Medicube spent 270 days developing the stabilization method that keeps all these retinoids active until they reach the skin. Combined with 0.01% Bakuchiol (plant-based retinol alternative), Niacinamide, Squalane, and Panthenol for a complete anti-aging serum that's easier on skin than traditional high-strength retinol. Has fragrance. 30ml.

• HPR (Hydroxypinacolone Retinoate) — 4th-Generation Retinoid — unlike traditional retinol that needs to convert multiple times before it works, HPR binds directly to skin receptors. This means faster results with significantly less irritation, peeling, and redness. The lead active in the 7-layer system.
• 5-Layer Retinol Complex — Multi-Depth Delivery — Retinal (converts once to active form), Retinol (classic), Retinyl Palmitate (gentle storage form), and additional retinoid derivatives. Each works at a different speed and depth. Encapsulated in liposomes that protect the retinoids from degrading and release them gradually into skin.
• Bakuchiol 0.01% — Plant-Based Retinol Support — works alongside the retinoids through a different pathway, boosting results without adding irritation. Bakuchiol is one of the only plant-based ingredients clinically shown to provide retinol-like benefits.
• Niacinamide + Squalane + Panthenol — Buffer + Hydrate + Soothe — Niacinamide brightens and strengthens the barrier. Squalane delivers lightweight moisture. Panthenol calms irritation. Three ingredients that make this potent retinol serum comfortable for daily PM use.
• 4 Plant Oils + Ceramide NP — Nourish + Barrier — Macadamia, Olive, Jojoba, and Grape Seed Oils nourish skin while the retinoids work. Ceramide NP replenishes barrier lipids. Prevents the dryness and stripping that cheaper retinol products cause.
• HA + Adenosine + Allantoin + Licorice — Hydrate + Smooth + Calm — Sodium Hyaluronate hydrates. Adenosine improves elasticity. Allantoin soothes. Dipotassium Glycyrrhizate calms redness. A complete support system for the retinoid complex.

Start with a pea-sized amount on targeted areas (fine lines, dark spots) every other day at the serum step of your PM routine. After two weeks, gradually increase to thin all-over application every evening. Follow with moisturizer. Has fragrance. 30ml.

⚠️ Contains multiple retinoids (HPR, Retinal, Retinol, Retinyl Palmitate). Use PM only. Apply SPF the following morning. Not recommended during pregnancy or breastfeeding.
