If you're a skincare lover in Iraq, you know that Cosrx is a K-beauty staple — but you might not know how wildly prices can vary from store to store. This week (May 17–24), we’ve crunched the numbers on TajPrice to find the Cosrx serums and essences where comparing prices saves you the most. Some products have a spread of over 300%! Here's your weekly guide to shopping smarter.
1. Cosrx Full Fit Propolis Light Ampoule Serum – 30ml
The biggest price gap this week belongs to 
Cosrx Full fit Propolis Light Ampoule Serum - 30ml. It’s available at only 2 stores, but the difference is jaw-dropping: from 7,000 IQD to 29,000 IQD – a spread of 314.3%. That means you could pay over four times more if you don’t check prices. Grab it at the best price and get intense hydration without the markup.
2. Cosrx Galactomyces 95 Tone Balancing Essence – 100ml
Cosrx Galactomyces 95 Tone Balancing Essence - 100ml is a multi-tasking essence that brightens tired skin, and it’s available at 4 stores. Prices range from 13,650 IQD to 29,750 IQD – a 117.9% spread. That’s a potential saving of over 16,000 IQD. Definitely worth a quick comparison before you buy.
3. Cosrx Advanced Snail 96 Mucin Power Essence – 100ml
Perhaps the most famous Cosrx product, 
Cosrx Advanced Snail 96 Mucin Power Essence - 100ml, is sold at 8 stores. The price range is 13,420–25,000 IQD, a spread of 86.3%. With so many retailers, you can easily find it for under 14,000 IQD if you shop around. Your skin (and wallet) will thank you.
4. Cosrx The 6 Peptide Skin Booster Serum – 150ml
This peptide serum is a powerhouse for elasticity and moisture. 
Cosrx The 6 Peptide Skin Booster Serum - 150ml is available at 6 stores, with prices from 17,500 to 28,000 IQD (spread 60%). The best price saves you over 10,000 IQD — not bad for a booster that preps your skin.
5. Cosrx The Niacinamide 15 Face Serum
A favorite for blemish-prone skin, 
Cosrx The Niacinamide 15 Face Serum is only at 2 stores but has a 45.5% spread (16,500–24,000 IQD). A quick check can save you 7,500 IQD. That’s almost half off!
6. Cosrx The Hyaluronic Acid 3 Serum – 20ml
Cosrx The Hyaluronic Acid 3 Serum - 20ml is a hydrating hero with triple hyaluronic acid. It’s at 6 stores, with a spread of 26.3% (19,800–25,000 IQD). Not the biggest gap, but 5,200 IQD saved is still a nice bonus.
7. Cosrx Advanced The Vitamin C 23 Serum – 20g
A high-strength vitamin C serum, 
Cosrx Advanced The Vitamin C 23 Serum - 20g ranges from 20,000 to 24,000 IQD across 3 stores (spread 20%). The best price is already reasonable, but why pay extra?
8. Cosrx Pure Fit Cica Serum – 30ml
Cosrx Pure Fit Cica Serum - 30ml is a calming, plant-based serum. It’s only at 2 stores, and prices range 13,500–15,000 IQD (spread 11.1%). Minimal difference, but still worth checking if you’re after the best deal.
9. Cosrx Retinol Oil Serum 0.5% – 20ml
For retinol beginners, 
Cosrx Retinol Oil Serum 0.5% has a small spread of 10.1% (20,440–22,500 IQD) at 2 stores. Every dinar counts, especially for a specialty serum.
10. Cosrx The Vitamin C 23 Face Serum
Another vitamin C option, 
Cosrx The Vitamin C 23 Face Serum, is at 2 stores with a tight 7.1% spread (16,800–18,000 IQD). The price difference is minimal, but if you’re already comparing, you might as well get the lower one.
The takeaway? For some Cosrx products, especially the Propolis Ampoule and Galactomyces Essence, prices can double or triple between stores. Always compare on TajPrice before you buy — it’s free, fast, and saves you real money. Happy shopping!
