COSRX - The Retinol 0.5 Oil - 20ml

Start with 2-3 times a week at night and gradually increase as tolerated. Some users can use it every night, while others may prefer less frequent use.

No. Retinol makes your skin more sensitive to the sun. Always use it at night and apply a broad-spectrum sunscreen in the morning.

Reduce the frequency of use, and consider consulting with a dermatologist.

Use with caution. Start with a very small amount and frequency, and monitor your skin's reaction. It's advisable to consult a dermatologist.

Results vary, but it may take several weeks or months of consistent use to see noticeable improvements in skin texture and the appearance of fine lines.

You can use hydrating serums and moisturizers to help counteract dryness. Avoid using with other highly active products at the same time, especially AHAs, BHAs, and Vitamin C, particularly when starting out.

Store in a cool, dark place away from direct sunlight and heat.

Reduce frequency of use. Start with once a week, then gradually increase as your skin adjusts. If irritation persists, consult a dermatologist.

Ensure consistent use and proper application. Results may take time. Consider increasing the frequency of use if tolerated. If no improvement is seen, consult with a dermatologist.

Check the expiration date. If expired, do not use. Properly store the product away from sunlight and heat.
