I have been using this serum for just under a month. The serum has a lightweight, non-sticky consistency. I have been shaking up the bottle before applying, otherwise the serum doesn't seem to mix properly and comes out clear and orange. The packaging recommends applying 2 - 3 drops. 2 drops was enough (as I ended up just focusing the product on my dark spots). I did struggle with the dropper a bit as it didn't seem to pick up much product - and since the bottle is not clear it's hard to gauge how much product is in there.
After using for a few days, I was a bit surprised to notice orange product in my hairline one afternoon! I realised it was the serum - this is why I ended up focusing on the dark areas away from my hairline/brows. It also meant that I changed from applying the product morning and night to night only unfortunately (unless I was working from home and wouldn't see anyone!). I also noticed that the serum had a strong, almost unpleasant scent on a makeup remover pad when I'd be washing my face at night (after applying it earlier in the day) which was a put off putting.
Despite this, it felt pleasant on my skin and there was no noticeable scent while it was on my skin. It didn't clog my pores which I really appreciated.
I will keep using the serum but I would not purchase it again. There are serums that are just as nice/nicer (and provide the same or better results) at the same or better price points. I think my dark spots may have faded a bit, however my pores look the same and overall my skin doesn't look brighter.
This product felt quite luxurious to start using, but didn't quite do everything it had promised. While I did notice that my skin tone looked more even the following morning after using it, I didn't notice any difference in my pores or fine lines throughout the trial period. It did also start to give me a breakout after using it every night for the first couple of weeks. While the consistency was nice and silky and it soaked in quickly and didn't feel tacky on my skin, I noticed an odd metallic smell on my hands the following morning after using it, even after washing my hands. I'm interested to see the results after even more use!
