How to Start Safely

Retinol is one of the most well-researched anti-ageing ingredients available — but it requires a gradual introduction. Begin with once per week for the first two weeks, then slowly increase frequency over 6–8 weeks as your skin builds tolerance. Most people can reach 3–5 times per week with a comfortable, well-managed routine.

How To Use

Step 1: Cleanse thoroughly and allow skin to dry completely (wait 20–30 minutes after cleansing for best tolerance).
Step 2: Apply a small amount — a pea-sized quantity is sufficient for the entire face.
Step 3: Follow immediately with the Organic Aloe Vera Gel or a gentle moisturiser to support comfort.
Step 4: Use SPF 50 every morning without exception — retinol increases photosensitivity significantly.

Complete Your Anti-Ageing Routine

Retinol MAX 5% is Step 2 of the Ammuri Anti-Ageing Routine — designed to work in sequence with:

• 🧬 Peptide Anti-Ageing Serum — Apply before retinol on retinol nights to support collagen synthesis and barrier integrity
• 🌿 Organic Aloe Vera Gel — Apply after retinol to calm, hydrate, and support skin comfort overnight
• ☀️ Vitamin C Day Cream SPF 50 — Essential every morning — non-negotiable when using retinol

When Will I See Results?

• Week 1–2: Skin may feel slightly drier or more sensitive as it adjusts — this is normal
• Week 3–4: Skin texture begins to refine; radiance improves
• Week 6–8: Fine lines appear softer; skin looks more rested and even
• Week 12+: Meaningful, sustained improvement in skin firmness and clarity with continued use

Individual results vary. Consistent use and daily SPF 50 are essential for optimal results.

Which Retinol Should I Choose?

New to retinol? Start with Supreme 2.5% and build up. Already using retinol regularly? MAX 5% or the Apple Stem Cell formula will deliver the most visible results.

Frequently Asked Questions

Q: Is 5% retinol suitable for beginners?
A: This is a high-strength formulation. If you are new to retinol, begin with once per week and build gradually. Read our Retinol 101 guide before starting.

Q: Why must I use SPF with retinol?
A: Retinol accelerates cell turnover, making skin more sensitive to UV radiation. Without daily SPF 50, you risk UV damage that counteracts retinol's benefits.

Q: Can I use retinol with brightening ingredients?
A: Yes — retinol and brightening actives like Kojic Acid and Vitamin C are complementary. Use brightening actives in the morning; retinol in the evening on alternate nights.

Q: What if my skin feels irritated?
A: Reduce frequency and apply the Aloe Vera Gel after retinol to support comfort. Never apply retinol to damp skin — always wait until skin is fully dry after cleansing.
