I have already used four bottles of this. Me and my dermatologist love it. It makes my skin smooth and hydrated with limited pores. I attached a photo of my skin for reference. This product is light weight and is not sticky like the other brands I have tried. I have very sensitive skin and it has not caused any reactions. It is scent free for anyone with allergies. It is very easy to use and functionable. I typically use it by washing my face and placing it on my skin when my skin is still wet so my skin will drink up water with it. Placing it on water has added an extra hydration boost to my skin. To use it you squeeze the dropper three drops on your hands or directly on your face and rub it on. The dosage says three drops but if I’m very dehydrated I use more. I attached a photo of my skin for reference. ... show more

    • Great Product
I was a little skeptical but gave this product a try. I have seen a difference in my face. My forehead is a little smoother, the lines around my eyes and mouth do not show that much any more. I have received compliments that I look younger. It absorbs really well and there is no stickiness after application. ... show more

    • Serum feels cool going on and holds skin moisture
After applying the serum, your face will feel refreshed, cool, and moisturized. It just takes two or three drops to cover your skin. The product is watery but dries after a few minutes. I use it just before I apply a cream moisturizer. My skin feels more hydrated. I haven't noticed an appreciable difference in fine lines, but I may not have used the serum long enough. ... show more

    • It Really Works
This product is a dream. It truly works at keeping the appearance of lines to a minimum. It is not greasy and absorbs easily. A little bit goes a long way, so you get many uses out of this small bottle.

    • Great product
I've been using this product for about a year now and really like it. I layer it in with other serums and moisturizers, so upon application it does feel a bit sticky, but once it soaks in there's no residue. I religiously use this at night as well as every morning prior to makeup application, and don't have any issues with it affecting my makeup. I can see small changes once it's been applied, but I'm not looking for a miracle here, just something to use as a preventative (especially since botox isn't in the budget right now), and it's certainly working in that regard. I do wish they'd make a slightly larger bottle as another option, because I tend to need a new one every six weeks or so, but that's probably because I use it twice daily and in generous amounts. I find the $35 pricing doable but not ideal, so I generally try to stock up whenever I find a sale going on. ... show more

Works beautifully to hydrate and improve skin tone. Redness has lessened with use!
