DO NOT USE IT DURING THE WARM/HOT SEASONS unless you have dry skin!! If you have the same skin type as me, it's still a good product, but it might feel heavy since it is quite thick. I HATE the dropper on this, it doesn't make any sense! The serum is too thick to be picked up nicely by the dropper, and you cannot use it fully since a lot of leftover product sits at the bottom of the bottle. I would buy this again in a heart beat if they rebottled this with some kind of pump and not that horrible dropper.
