Retinol 5%: The Anti-Ageing Ingredient That Actually Delivers — And Why Ammuri's Formula Is Different
The Gold Standard of Anti-Ageing — Finally at Full Strength
If there is one ingredient that dermatologists, scientists, and skincare experts universally agree on, it's retinol. Decades of clinical research confirm it as the most effective topical ingredient for reversing visible signs of ageing.
But here's the problem: most retinol products on the market are underdosed. The Ammuri Retinol 5% Serum changes that entirely.

Retinol is a form of Vitamin A that, when applied to the skin, is converted into retinoic acid — the active form that triggers cellular change. It works by:
- Accelerating cell turnover — pushing fresh, new skin cells to the surface faster
- Stimulating collagen production — rebuilding the skin's structural support network to reduce wrinkles
- Inhibiting collagen breakdown — blocking the enzymes that degrade collagen with age and UV exposure
- Regulating sebum production — reducing oiliness and minimising enlarged pores
- Fading pigmentation — accelerating the shedding of pigmented cells for a more even complexion
Why 5% Makes the Difference
Clinical studies show a clear dose-response relationship with retinol — higher concentrations deliver faster, more significant results. At 5%, the Ammuri Retinol 5% Serum delivers faster visible reduction in fine lines, more rapid improvement in skin texture, stronger collagen stimulation, and more effective pore-minimising action.

The Ammuri Advantage: Encapsulated Retinol Technology
Ammuri's Retinol 5% Serum uses encapsulated retinol technology — micro-encapsulating retinol molecules in a protective shell that releases retinol gradually for sustained delivery, dramatically reduces irritation, protects retinol from oxidation, and allows higher concentrations to be used safely.
Your Results Timeline
- Week 1–2: Skin may feel slightly dry or experience mild flaking — this is normal and temporary
- Week 4–6: Skin texture visibly smoother, pores appear smaller, complexion brighter
- Week 8–12: Fine lines and wrinkles visibly reduced, skin firmer and more youthful
- Month 6+: Significant, sustained improvement in skin age appearance
How to Use
Evening only (retinol breaks down in sunlight). Apply 2–3 drops to face and neck, follow with a rich moisturiser, and always apply SPF 30+ the following morning. Our Vitamin C SPF50 Day Cream is the ideal morning companion — combining broad-spectrum sun protection with brightening vitamin C. Begin with 2–3 nights per week and increase to nightly as your skin builds tolerance.
Frequently Asked Questions
What percentage of retinol is most effective for anti-ageing?
Clinical studies show that higher concentrations of retinol deliver faster and more significant results. The Ammuri Retinol 5% Serum uses encapsulated technology to deliver high-strength retinol safely and effectively.
What is encapsulated retinol and why is it better?
Encapsulated retinol is micro-encapsulated in a protective shell that releases the active ingredient gradually into the skin. This reduces irritation, prevents oxidation, and allows higher concentrations to be used safely — delivering better results with less sensitivity than standard retinol.
Can I use retinol every night?
Start with 2–3 nights per week and gradually increase to nightly use as your skin builds tolerance, typically over 4–6 weeks. Always follow with SPF 30+ the next morning.
Is retinol safe for beginners?
Yes, with the right approach. If you're just starting out, read our beginner retinol guide to understand what strength retinol you should start with before progressing to a 5% formula.
