If you're a Cosrx fan in Iraq, you know these K-beauty favourites don't come cheap — unless you know where to look. This week (May 19–26, 2026), we've crunched the numbers across multiple Iraqi stores to find the products with the biggest price spreads. The result? Some serums and essences cost more than triple in one shop versus another. Here are the top deals where comparing prices pays off most.
1. 
Cosrx Full fit Propolis Light Ampoule Serum - 30ml — Price spread: 314.3%
This lightweight propolis ampoule is a hydration hero, but prices vary from just 7,000 IQD all the way up to 29,000 IQD. That's a potential saving of 22,000 IQD if you buy smart. Available at only 2 stores, so check both before buying.
2. 
Cosrx Galactomyces 95 Tone Balancing Essence - 100ml — Spread: 117.9%
