Medicube Deep Vita A Retinol Serum (30 ml) is a potent anti-aging wrinkle serum driven by an advanced 1% HPR + 5-Retinol Complex. Its key highlight is the use of 4th-generation retinoids delivered via a liposomal system, ensuring deep skin penetration for fast results with minimal risk of irritation.

• Retinoid Complex (HPR, Pure Retinol, Retinal, Retinyl Palmitate): Powered primarily by Hydroxypinacolone Retinoate (HPR), a highly stable form of Vitamin A that binds directly to skin receptors without requiring multi-step conversion. This accelerates cell turnover, boosts collagen production, smooths fine lines, and enhances firmness.
• Bakuchiol: A plant-derived retinol alternative that amplifies the anti-aging effect and refines skin texture without causing redness.
• Niacinamide: Brightens dark spots and post-acne marks, minimizes pores, and evens out skin tone.
• Collagen Complex (3%): Provides intense hydration, plumping the skin and increasing elasticity.
• Soothing Barrier Complex (Squalane, Panthenol, Ceramides): Restores the skin's moisture barrier, deeply nourishes, and counteracts dryness or peeling often associated with retinol use.

1. Weeks 1–2: Apply a tiny amount (the size of a grain of rice) every other night directly onto wrinkle-prone areas like the forehead, between the brows, and nasolabial folds.
2. Week 3 onwards: If your skin has adapted well without significant irritation, you can transition to applying a thin layer over the entire face every night.
3. Essential Rules: Apply to clean, dry skin during your nighttime routine. Always follow up with a moisturizing cream. In the morning, never skip sunscreen (SPF), as retinol increases the skin's sensitivity to UV rays.
