I can really see a difference in my skin after a week of using it. I noticed that my pores are way smaller and I have less breakouts. However, it does irritate my eczema a little bit, just a little, nothning I can't manage. Oh and the tingling sensation can be overwhelming at times so I like to dilute it with a drop of moisturising serum when I first started. but overall, very happy with the results.  I wished I had tried this sooner!
