Customer Reviews
Good quality, quick delivery
I ordered the Niacinamide Vitamin B3-10% Serum and it arrived pretty fast, took about 6 days to get to my place in California. The serum itself felt good, not sticky at all. My skin definitely looked a bit less oily after using it for a couple weeks. Packaging was secure too.
Consistent results with serum
This was my third time buying from CosIQ and they're still reliable. Got the Sunscreen Serum SPF 50 this time, along with another bottle of the Vitamin C-8% Serum. The sunscreen is really light, not greasy or anything, which is great for daily use. My first order was just the Vitamin C, then I tried the AirGel moisturizer, and all of them have been good quality. They always ship pretty quickly, and the products consistently deliver what they promise. That's why I keep coming back for my skincare needs.

Can you use more than one discount code on CosIQ? I have one from an influencer but also want to use the first order discount.
hey, was thinking of trying the CosIQ vitamin c serum but heard some stuff about fakes online. are these legit or should I just stick to Sephora brands?
