Your Essential Guide to Starting Retinol

Retinol is powerful, but using it wrong can backfire. Here’s how to do it right:

• Start Low and Slow: 1–2 nights per week → build tolerance over weeks.

• The Sandwich Method: Moisturiser → retinol → another thin layer of moisturiser (great for sensitive skin).

• Patch Test: Always test before applying all over your face.

• Understand Purging: Tiny whiteheads in usual breakout areas = normal. Painful, itchy irritation = stop and reassess.

• Sunscreen Daily: Retinol without SPF is pointless. Protect with SPF 50 PA++++ every morning.

• Absolute Beginner? Start with COSRX or Innisfree.

• Sensitive but curious? The beauty of Joseon Revive Eye Serum is foolproof.
