The Retinol 0.5 Oil [20ml]

Share information about your product.

COSRX The Retinol 0.5 Oil is 0.5% pure retinol in a squalane and soybean oil base — no water, which keeps the retinol stable. It comes with clinical numbers most retinol products do not publish, and with a structured four-week introduction schedule, because starting too fast is the single most common reason retinol fails.

🎯 What It Does

• Softens wrinkles measurably — 22.02% improvement on forehead lines over 4 weeks
• Works on the eye area — 17.68% improvement on eye-area wrinkles; 18.40% on nasolabial folds
• Improves elasticity — 16.91% external and 13.43% internal elasticity improvement
• Lifts and defines — 13.78% at the mouth corner, 13.54% at the chin
• Refines pores fast — 48.87% pore volume and 45.74% pore area improvement in just 2 weeks
• Stays stable — the water-free oil base protects the retinol from degrading

🔬 Key Ingredients

• Retinol 0.5% — pure retinol at an effective but manageable concentration
• Squalane & Soybean Oil — the anhydrous base; nourish and offset retinol dryness
• Tocotrienols & Tocopherol — Vitamin E antioxidants supporting stability

📋 How to Use

1. Weeks 1–2: use 2–3 times per week at night. After cleansing, at the moisturiser step, apply 1–2 drops to areas of concern — under eyes, mouth, forehead and neck.
2. Week 3 onward: apply every other night, and you may spread over the entire face.
3. Tap in with fingertips from the inside out and let it absorb.
4. Extend or shorten the adaptation phase as your skin dictates — stay at each stage until there is no discomfort.

Important. Retinoids increase sun sensitivity — daily SPF is essential. Do not use alongside other retinoid products. Avoid entirely if pregnant or breastfeeding. Clinical figures based on trials of 20 subjects.
