I use this in conjunction with a bit C serum such as Medik8 Tetra luxe serum for added antioxidant support I will be using it with the Ordinary but C serum this time and it mixes perfectly or can be added afterwards as I'm always in a rush I mix then before moisturizer. Excellent product at great price point .

My skin didn’t get irritated by this and seems to work well with my current skincare.

I use it all morning with vitamine c serum

I used this for a couple of months but didn’t find any difference in my skin

I mix this with other serums from the ordinary make sure to check it’s safe - depending on my skin concerns I will use the correct serum mix to a cream like consistency and apply to my skin
