Strong Retinol Guide (0.5–1%)

High-strength retinol can deliver impressive results – but only if your skin is ready. Jumping straight to 1% is one of the fastest ways to damage your barrier.

Who is strong retinol for?

• People who have used low-dose retinol consistently for 6–12 months.
• Those with visible photo-ageing, stubborn texture or deeper lines.
• Skin that tolerates actives well.

0.5% vs 1% – what’s the difference?

0.5% retinol is a strong but manageable upgrade. 1% should be treated almost like a prescription-strength product.

How to introduce strong retinol safely

1. Drop back to 1–2 nights per week when switching.
2. Use the “sandwich method” – moisturiser → retinol → moisturiser.
3. Pause other strong actives for a few weeks.
4. Watch for early signs of over-irritation.
