Have been using this nearly a month and so far its working very well. Have jad lots of compliments about my skin. No irritation and no strong smell.

It didn’t really do anything for my skin, didn’t see any results.

I've been using retinol products for a while now. This one is a really good quality product. It doesn't cause any irritation. After a month i could see results. It reduced fine lines and made my skin texture better. Highly recommend

Sunday Riley is an expert in retinol and vitamin c products. I continually use this serum for 2 years already, my lines became less, blemished disappeared and sun spots are much lighter than before. It’s a holy grail. 

You have to be patient and not expect over night miracles with this product when it comes to lines or scars, but this really works for me. I had quite a bad scar on my cheek which has now gone, i had it for a few years prior to using this product. Fine lines have reduced significantly and my skin is generally alot fresher looking. I'd say it hasnt done a great deal for enlarged pores or hormonal spots (but not sure if fhis is meantto work for this). It would take a lot for me to switch to another product as this is one really works.
