Who It’s For

Choose Extreme Brightening Serum if you specifically want the Kojic Acid + Alpha Arbutin formula story. If your skin is reactive, patch test and introduce gradually rather than assuming every brightening active will suit every skin type.

How to Use

1. Apply a small amount to clean, dry skin according to the current packaging directions.
2. Allow it to absorb before moisturiser.
3. Use morning and/or evening according to skin tolerance.
4. During the day, finish with an appropriate broad-spectrum sun-protection product and follow its exact label directions.

Extreme vs Exosome Brightening Serum

The Extreme Brightening Serum is positioned around Kojic Acid + Alpha Arbutin with Hyaluronic Acid, Aloe Vera and Vitamin E. The Exosome Brightening & Hydration Booster Serum is positioned as a separate multi-active formula with Kojic Acid, Glutathione, Vitamin C and Alpha Arbutin.

You do not need to layer both serums. Choose one according to the ingredient profile on the physical product you receive and your skin tolerance.

Realistic Expectations

There is no universal 4–8 week or 8–12 week result promise. Visible marks change at different rates depending on their cause, depth, age, sun exposure, individual skin and routine consistency.

Frequently Asked Questions

What results should I expect?
It is cosmetic skincare intended to improve the appearance of visible dark spots and uneven-looking tone. Results vary by skin and routine.

Is it guaranteed vegan or cruelty-free?
We only make those claims where current supplier/formula documentation supports them. Check the current packaging or contact Ammuri if certification or ingredient origin is important to your purchase.

Should I layer it with Exosome Serum?
Not automatically. One well-chosen brightening serum is usually clearer and easier to assess for tolerance.

Do I need SPF50 specifically?
Use an appropriate broad-spectrum sun-protection product and follow the exact rating, amount and reapplication directions on its current packaging.

Important: This is cosmetic skincare, not a treatment for melasma or another diagnosed pigmentation disorder. Stop use if persistent irritation occurs.
