Who It’s For
Choose this serum if you want the Ammuri Exosome-positioned formula and a multi-active brightening routine. If your skin is reactive, patch test and introduce gradually rather than assuming every brightening formula will suit every skin type.
How to Use
- Apply a small amount to clean, dry skin according to the current packaging directions.
- Allow it to absorb before moisturiser.
- Use morning and/or evening according to skin tolerance.
- During the day, finish with an appropriate broad-spectrum sun-protection product and follow its current label directions.
Exosome Serum vs Extreme Brightening Serum
These are presented as separate Ammuri product pages with different ingredient stories. The Exosome Serum is currently positioned around Kojic Acid, Glutathione, Vitamin C and Alpha Arbutin. The Extreme Brightening Serum is positioned around Kojic Acid + Alpha Arbutin with Hyaluronic Acid, Aloe Vera and Vitamin E.
You do not need to layer both. Choose one formula according to the ingredient profile shown on the physical product you receive and your skin tolerance.

Realistic Expectations
There is no reliable universal 2-, 4-, 8- or 12-week results schedule. Visible marks change gradually and at different rates depending on the type of mark, skin, sun exposure and consistency of use.
Frequently Asked Questions
Does this serum regenerate skin cells?
We do not make that medical or biological claim. It is a cosmetic brightening and hydration serum.
Is it guaranteed to suit sensitive skin?
No. Patch test if your skin is reactive and stop use if persistent irritation occurs.
Should I use it with the Extreme Brightening Serum?
Not automatically. One well-chosen brightening serum is usually a clearer routine than stacking two similar products.
Do I need SPF50 specifically?
Use an appropriate broad-spectrum sun-protection product and follow the exact protection rating, amount and reapplication directions on that product’s current label.
Important: This is cosmetic skincare, not a treatment for melasma or another diagnosed pigmentation disorder.
