Week 1–2: Introduction phase
Start with a low-concentration retinol (0.025% to 0.1%) applied once or twice per week at night. Cleanse, wait for skin to dry fully, apply a thin layer of retinol, then follow with moisturiser to buffer any dryness.
- Cleanse with a gentle, non-stripping cleanser before applying retinol.
- Let skin dry for 10–20 minutes before applying to reduce sensitivity.
- Apply a pea-sized amount evenly across the face.
- Follow with a hydrating moisturiser to reduce peeling and tightness.
