Frequently Asked Questions

How do I start using retinol?

Begin with 0.025-0.05% concentration, applied 2-3 nights per week. Gradually increase frequency as your skin tolerates. Always follow with moisturizer and wear SPF daily.

Can I use retinol every night?

Once your skin has adapted (usually 8-12 weeks), nightly use of 0.1-0.3% retinol is safe for most people. Start slow to minimize the 'retinization' adjustment period.

What is the difference between retinol and retinoids?

Retinol is an over-the-counter form of Vitamin A. Prescription retinoids (tretinoin, adapalene) are 10-20x more potent. Korean beauty brands often use gentler retinol esters for daily use.

Should I use retinol in the morning or at night?

Always at night. Retinol degrades in sunlight and increases photosensitivity. Apply the next morning's SPF 50+ to protect skin.

What Korean products contain retinol?

Top Korean retinol products are available on Olive Young Global. Look for COSRX Retinol 0.1 Cream, Some By Mi Retinol Intense Reactivating Serum, and Medicube brands.
