"[This review was collected as part of a promotion.] I have never tried anything from this brand before as they are a more luxurious brand to me due to their price point, but this serum was a really lovely product to add into my routine. A little does go a long way with this so even though it is expensive for what you get, it should last you for quite a while. It is fragranced so if you're not a fan of scented products, then this will not be for you. I do have sensitive skin and usually don't take well to products containing vitamin c but this didn't cause a reaction at all. Haven't noticed any instant results but hopefully once I use this more often, I will begin to notice the full results of this serum."
