A potent nighttime retinol oil that helps improve fine lines, wrinkles, texture, and elasticity, while deeply nourishing and protecting the skin with squalane and Super Vitamin E.  

Description:

COSRX The Retinol 0.5 Oil is a concentrated antiaging treatment formulated with 0.5% pure retinol, squalane, and Super Vitamin E (tocotrienol + tocopherol) to support skin renewal and hydration. Retinol (a form of Vitamin A) is known for stimulating cell turnover, boosting collagen production, and improving the appearance of fine lines, wrinkles, and uneven texture. Squalane helps lock in moisture and protects the skin barrier, while Super Vitamin E delivers antioxidant benefits to defend against environmental stressors. This silky oil formulation absorbs smoothly without heaviness and is especially suitable for users who are already accustomed to retinol and want a stronger, more intensive retinol product.

How to use:

1. Evening only: Retinol should be used at night — it can degrade in sunlight. Start slowly:
2. Apply 1–2 drops to clean, dry skin 2–3 times per week at night for the first 1–2 weeks. Build tolerance: If well tolerated, increase to every other night after about 3 weeks.
3. Gently massage into the face, focusing on concerned areas (avoid eye and lip areas). Follow with moisturizer (optional) to lock in hydration.
4. Use sunscreen daily during the day — retinol increases sun sensitivity.
5. Patch test before full application to check for sensitivity.
