I've been using this Vit C serum for over a month and I'm quite satisfied with it. It leaves a slightly sticky feeling after application but after I moisturise it's gone and it doesn't bother me. However, I'm not quite sure if it actually does improve my skin or if it's actually brightening. I have quite oily, acne prone skin with large pores and luckily, it hasn't broken me out. After I finish the bottle, I will probably try the CE Ferulic from Skin Ceuticals, just to see a bigger difference.

Love the texture and the subtle scent. It’s quite moisturising. Where I live it’s hot & humid all the time and sometimes I don’t need moisturiser. The vitamin C is sufficient. I just top it up with sunscreen and I’m good to go!

Doesn’t absorb very well. Gives a weird shine to the skin and I do not like it. Would prefer a lighter cream. This is by far the thickest cream I’ve ever seen. More like an old school cold cream. I use almost all of SRs oils, cleansers and Good Genes etc. But this is my least favorite product. Wish I had not bought it just before summer :( waste of money.

It's not my first vitamin c I use. I really love it. It's not streaky, it doesn't smell bad and the formula is hydrating and creamy, not oily and very nourshirng.. my only complaint is the price and I actually ran out really quickly it only lasts a month and a half, and actually a bottle lasts about two to three months, it was really confusing for me. I'm not going to buy it unless there is a real sale on Sunday Riley, I usually use vitamin c from klairs and I'm in love with it but I had to try this one.

Oh my god this thing seriously brightens without drying your skin out. It just gives you that inner glow instantly without getting sticky. It didn't irritate my skin at all. I noticed a really brighter complexion plus fading of sun spots just after using it for 3 weeks. The best part is you just need a small amount and it smells amazing as well. Definitely a staple product!
