This serum is FANTASTIC. I 100% see a major difference in my skin when using this product and I can't get enough of it. I'm not crazy about the smell of this product, it smells really strongly of lemongrass which for some reason I just really dislike, but the smell doesn't stay around for very long so it's something I can get over because it really works. This product is marketed as an anti-ageing and I've noticed a slight difference in the fine lines that have started to develop on my forehead and in between my brows from all the facial expressions I make, they have faded a lot and I've also noticed my skin hasn't been as dehydrated and it hasn't been overproducing oil to compensate which is awesome. My makeup has gone on really smoothly since I've used this serum and I have loved it. The product instructions are to apply the serum to cleansed skin and then wait half an hour before applying moisturizer so sometimes I only apply the serum and go to bed but on nights where my skin feels extra dry I apply the Tarte Maracuja Oil over the serum and then go to sleep.
