Feels good on skin, smell is not too bad. I still have not noticed major changes on my spots but i do like that my skin feels softer.


My skin feels great with this serum! It packs double duty with the brightening from vitamin c and the hydration from the hyaluronic acid. My skin feels plump and fresh. The serum glides and absorbs easily, it doesn't pill or feel sticky. My dry sensitive skin feels good and I haven't noticed any breakouts. Yes, it does have that funky vitamin c smell to it, but I get over it. The price is pretty good for the size of the bottle and the quality of the serum. I'll definitely continue to use it and would consider repurchasing.


When I read reviews about scent smelling like wet cat food, I was so prepared for an uncomfortable experience. However, I’m pleasantly surprised that although there is a bit of smell, it’s not too bad and after a few minutes it’s all gone. The product works well too, my face is extra soft and supple now and I’ve been using it for a few weeks


It smells like tuna but it fades within a few minutes, I use it under my moisturizer and I love it! Can definitely see the difference it plump and it definitely brightened my skin it’s wonderful!!


love this product! smells a little like coffee to me, but i like it !
