COSRX The Retinol 0.5 Oil provides powerful anti-aging care for experienced users of retinol. It is formulated using 0.5% stabilized, pure retinol and treats progressive signs of aging such as loss of elasticity and dryness. It is recommended for "intermediate-level" retinol users requiring a highly concentrated retinol treatment. Clinical trial results demonstrate improvement in appearance of wrinkles and in skin elasticity (firmness) within just 4 weeks.
COSRX is known for its short ingredients list that features high quality and effective extracts and compounds that help trouble-prone, dry and dehydrated skin, as well as aging and sensitive skin. All COSRX products are 100% made in Korea and cruelty-free.

Patch test first on a small area (like your jaw or behind your ear) before using it on your full face.
Use only at night on clean, dry skin after cleansing and toning.
Apply a thin layer of moisturizer first if you’re new to retinal or have sensitive skin.
Dispense 1–2 pea-sized drops of retinal serum and spread a light, even layer over your face, avoiding the eye and lip area.
Follow with another layer of moisturizer to reduce dryness and irritation.
Start 2–3 times a week, then slowly increase to nightly use once your skin adjusts.
Wear sunscreen every morning because retinal makes skin more sun-sensitive.
TIP:
Avoid using retinal right after laser treatments, physical scrubs, or chemical peels.
Mild flaking, redness, or irritation can happen at first, this is normal while skin adjusts.
Do not combine with strong acids like AHA or BHA in the same routine.
