How to Choose the Right Retinol Strength

Retinol works best when matched to your skin's current experience level. Starting at the right concentration helps you build tolerance gradually and get the most from the ingredient over time.

• Retinol 2.5% — The ideal starting point for retinol beginners and those with sensitive skin. Gentle enough to minimise irritation while still encouraging skin renewal.
• Retinol 3.5% — The natural next step for intermediate users who have built tolerance at lower concentrations. Suited to those targeting more established fine lines and uneven texture.
• Retinol 5% Apple Stem Cell (this product) — Ammuri's most advanced retinol formula. Designed for experienced users seeking maximum skin renewal, combining high-potency retinol with regenerative Apple Stem Cell technology for long-term anti-ageing results.
