Why You’ll Love It

Before You Choose 5%

Choose this serum if you already use retinol comfortably and specifically want Ammuri’s highest-strength standard option. Higher strength is not automatically better; a lower strength used consistently can be a better choice than a stronger formula that repeatedly irritates your skin.

If you are new to retinol, start with Ammuri Retinol 2.5%. If you want a step-up option, compare Ammuri Retinol 3.5%.

How to Use

1. Use in the evening on clean, completely dry skin.
2. Apply a small amount, avoiding the eye and lip areas.
3. Start 1–2 evenings per week and increase gradually according to skin tolerance.
4. Follow with a gentle moisturiser.
5. Use broad-spectrum SPF every morning while using retinol.

Which Retinol Strength Should You Choose?

2.5% — lower-strength starting option.
3.5% — step-up option for experienced users.
4% — high-strength intermediate option.
5% — Ammuri’s highest-strength standard retinol serum.

Higher strength is not automatically better. Choose the lowest strength that gives you a comfortable, consistent routine.

What to Expect

Retinol works gradually. Over time, skin may look smoother, more refined and more even in appearance. Some dryness can occur while adjusting; persistent burning, soreness or significant peeling are reasons to reduce frequency or stop use.
