I have very oily skin and can't use a lotion or cream. I bought this to use as a moisturizer before makeup application.  It glides on silky smooth, absorbs quickly and is not sticky as others have stated. I love it! It gives my skin a nice glow without being shiny.  It moisturizes and smooths my skin perfectly!

This was recommended by a makeup artist on Instagram as a pre-primer because it has a very tacky finish. That is definitely true, it goes on very smooth but definitely sticky. If not using as a primer, you definitely need something after this. I used it as a primer and at night before a night cream and it worked well under both. It holds products in place well. Additionally, the ingredient list is amazing and makes me feel a bit better about the price. I was able to get this on sale, and you really only need a small pump so I imagine this will last awhile (and I don't plan on using daily). I would recommend this as a primer or for someone looking to add a little luxury to their regimen.

I've been using this a couple of months now and have used about nearly half the bottle, and I've noticed a great difference in my skin! I use it each night after spraying La Roche-Posay's Thermal Spring Water, then follow with a light moisturizer and face oil. I use it all over my face, around my eyes, on my neck and décolleté, so I'm pretty liberal with it, but it has a very thin texture so spreads very easily. A little goes a long way. It has a nice fresh scent too. The only thing is that it is slightly tacky at first, but quickly dissappates and then I don't notice it at all. In the morning, I spray the thermal spring water on my face as well after cleaning with my clarisonic, then I use this wonderful serum mixed with a bit of BB Cream, spf, and highlighter. I think it helps to thin out my makeup, giving me a somewhat sheer look. This product is just fantastic! My acne scars have faded, a spot of melanin on my cheek has also lightened, but not sure if it's this or my Obagi Nu-Derm #3 that I use as a spot treatment. Overall though, this has given my skin more clarity, evened out my skin tone, and kept any fine lines and wrinkles at bay! Great, great product!

I use this product with Exuviane Evening Restorative Complex. My skin looks good for a 75 year old.

After reading reviews here on the product which were very favorable I decided to buy it. My dislike for the product is that it is very sticky after applying and doesn't absorb well at all. If you use it in the evening before bed your face will stick to the pillow.

Lean finely textured beef is made from beef heated and spun in a centrifuge to separate the meat from the fat, before the final product is treated with a puff of ammonium hydroxide gas to kill any bacteria.

good texture - I like how it makes my skin feel smooth but not greasy - all day long.

I have not noticed a significant difference in fine lines but it does go on nice and smooth and goes well under make-up.

smooth as silk.. slides on .. it is perfect.. BIONIC serum makes your skin feel like silk

I really like Exuviance Vespera Bionic Serum, because I have noticed my skin seems less dry and has a better all over appearance. It is expensive but it lasts a long time since you only use a small amount.
