    Great Multi Purpose Serum

    This is a great serum with multiple benefits. Very light weight and absorbs into the skin quickly. I use this after my toner. Has made a difference in my skin and it totally boosts the effectiveness of my other skincare products I use after. Highly recommend. Been using this twice a day for a year.

    HORRIBLE

    Runny and leaves face sticky and gross. I put it on & washed it off within 5 minutes. This is the worse face product I have ever purchased. I would have given it a negative review if I could. I would advise that this be removed from Target’s App/shelves.

    Strange packaging/USED

    I purchased this product from Target .com and was really disappointed the bottle was small , looked like it had already been used and didn’t come in a box it was shipped in this plastic bag. Definitely caution when purchasing this product

    Good

    Love this. Works great, very thin so it absorbs good. Doesn't pill with rest of skincare.

    Sticky with a rash :(

    Only one verified review except mine ? Interesting that people have clamored after this. I bought in as well…. I really think this is just water with glycerin. It turns whitish when I smoosh it around my face. Feels tight and gives me a red rash. Glycerin is cheap people …go get some and make your own face plumper. I will stay away from the hype next time, as I like my money. If it works for you fantastic. But sticky, hot and rashy for me :(

    Great skin serum for 30+ skin

    Felt great on my skin, improvement of lines and my skin feels firmer. I was using another brand at $100 but didn’t feel it made a difference.
