Too strong
It was a bit to strong when I decided to add vit C in my routine. For the beginners I recommend to find a lower strength vit C. For my rosacea/flashing skin was too strong.

Worth it
I did think a lot to buy or not to buy, and I did. It’s a great serum, skin is silky and smooth after applying, not greasy or oily, just leave to absorb a bit before applying a moisturiser

My favorite!
And amazing serum! I'm on my 3rd bottle and don't plan to stop! Its not irritating, with a great texture and makes a huge difference on my skin - its more even, bright and moisturized. The difference between this one and simple Vitamin C serum from Medik8 is, as I know, in the fact that this one has Squalane, which you need to consider depending on how your skin reacts to it. Also it has some more oils, including citrus one (be careful if you know you're allergic to it) and the concentration of Vitamin C is a bit higher that in the regular version. Also, because of the Squalane the serum feel a bit greasy, which is more just a feeling, its not at all when you put onto you skin. My combination skin reacts perfectly to it, and I use in the mornings following with make up and it doesn't make sebum production worse

This vitamin C serum is amazing. I'm on my 3rd bottle. My skin feels silky smooth after applying this. It doesn't leave skin feeling greasy or oily. It's pricey but worth it.

Not working
Why is this so pricey? It hasn’t made any difference to my skin or pores. My skin still looks red and with acne scars and large pores, no difference whatsoever, I wasn’t expecting major results but still. It’s very expensive to get nothing done
