About the Product
COSRX The Retinol 0.5 Oil is a concentrated nighttime treatment featuring 0.5% pure retinol in a lightweight squalane base. Retinol is a form of vitamin A that supports skin cell turnover, helping to smooth texture and reduce the appearance of fine lines over time. The oil format absorbs easily and helps minimize the dryness that can sometimes come with retinol use.
Who is This For?
This mid-strength formula works well for anyone looking to level up their retinol routine, especially if you've already used lower concentrations like 0.1% or 0.3%. It's particularly helpful for concerns like fine lines, uneven texture, or dullness, but suitable for normal, combination, and oily skin types.

FAQs
Q: Can I use COSRX The Retinol 0.5 Oil if I'm new to retinol?
A: This 0.5% concentration is considered mid-strength and is recommended for those who have previously used lower-concentration retinol products; beginners should start with a 0.1% or 0.3% retinol first.
Q: Why is this retinol formulated in an oil base?
A: The squalane oil base helps deliver retinol effectively while providing emollient properties that can buffer potential dryness and irritation associated with retinol use.
Q: Can I use this retinol oil with niacinamide?
A: Yes, niacinamide is generally compatible with retinol and may help support skin barrier function when used together.
Q: Can I use this with other actives like vitamin C or AHAs?
A: It's best to skip other exfoliating actives on the nights you use this oil to avoid irritation.
Q: How long before I can use this retinol every night?
A: After approximately 3 weeks of consistent use at 2-3 times per week without irritation, you can gradually increase application frequency to nightly use.
Q: When should I apply this in my routine?
A: Apply a few drops to clean, dry skin at night after toner and before moisturizer, and always follow with sunscreen the next morning since retinol increases sun sensitivity.
Q: How should I store this product?
A: Keep it in a cool, dark place away from direct sunlight to maintain the retinol's stability and effectiveness.
Q: Who should avoid using this product?
A: Pregnant or breastfeeding individuals should avoid retinol entirely, and anyone with highly sensitive or compromised skin should consult a dermatologist before use.
How to Use
Cleanse face thoroughly and ensure skin is completely dry before application. Dispense one to two drops of product onto your hand. Tap the oil onto your face with fingertips and gently massage into skin, avoiding the eye area and lips. Follow immediately with a moisturizer to seal in the product and support skin hydration. Begin use at 2-3 times per week, then gradually increase frequency to nightly application after approximately 3 weeks of consistent use. Apply broad-spectrum sunscreen every morning, as retinol increases photosensitivity. Conduct a patch test on a small area of skin before applying to the full face.
