Bought this because my skin had broken out loads in lockdown and aside from a lot of uneven skin tone from old spots I was getting some weird redness on my cheekbones. I also permanently had dry, scaly feeling skin around my chin and nose (have had this for a couple of years). This product was like a miracle cure as soon as I started using it, it got rid of the dry scaly skin on my nose and made my skin generally so much softer, as well as calming the redness on my cheekbones and the breakouts. A couple of months in, I still have some sun damage on one cheekbone that I don't think it has really altered, and for a while, I thought it was making my blackheads worse, although this has gone back to normal now (i.e. I still have them all the time but they are not getting worse). My brother kept getting really bad flare-ups of red inflamed skin on his nose that he was treated with steroid cream and I persuaded him to buy this serum because of the impact it had had on my dry skin, and it has really sorted it out for him - he doesn't use the steroid cream anymore and has had no more flare-ups so far. So in conclusion - it isn't really what it is advertised to do but for dry, scaly skin or irritated dry skin I would massively recommend it! And I do feel like it has generally controlled my breakouts and improved skin tone. I should say that like other people have said it does feel a bit tacky for a while after application and is a bit shiny, but it eventually soaks in (I try to use it while my toner is still a bit damp, that way I can use less and spread it more easily). Also under foundation and powder (use the Ordinary serum foundation and NYX powder), it feels fine. I don't get any redness from it but I use glycolic acid toner so my skin is used to chemical exfoliants.
