    Let’s Be Honest… I Bought This Hoping for Magic
    Let’s be honest-anytime a product says “plumping” or “volume,” my expectations immediately split into two categories: absolutely nothing happens, or I convince myself something happened because I spent money on it. This one actually surprised me. The texture is lightweight but nourishing, and because it’s anhydrous, it feels a little richer without being greasy or heavy. I started using a small amount consistently in areas where my skin looked a little tired or less full, and over time my skin definitely started looking smoother, healthier, and more refreshed overall. One thing I really appreciate is that it doesn’t just sit on top of the skin making you shiny for five minutes and then disappear into disappointment. It absorbs well, layers nicely with the rest of my routine, and leaves my skin feeling soft instead of sticky. The biggest thing I noticed is that my skin just looks more “awake” and healthy lately-like I’ve been drinking enough water, sleeping properly, and making responsible life choices…which may or may not be true. I’ve tried a lot of skincare products that sounded impressive and did very little. This one actually earned a permanent spot in the routine.

    Good product
    I've used a few different volufiline’s and I like this one best. You get a tingling sensation that you don't get from other brands. Most of them are around the same price but this brand seems to have a bit of a larger bottle. I recommend purchasing this product. My smile lines are reducing significantly. I stopped putting it on my under eyes because I read somewhere it can make them worse. You also have to continue using it to keep the changes.

    This makes my face feel amazing
    I love how this makes my face feel! It’s still early to tell how effective it’ll be, but I saw friends yesterday that I hadn’t seen in almost a month and they commented how well rested and useful I looked! It was pretty flattering

    Recommending with caution
    I noticed a slight difference but it did cause some irritation around my eyes. I have very sensitive skin so it’s not that hard to imagine. I have hallows under my eyes and dark circles. It helped lighten them slightly but it also worsened puffiness that was so subtle you wouldn’t have even noticed it. So while it helped the hollows it also caused puffy bumps where people normally would get eye bags. I eye tried to apply with a queue tip just around the edge of the dark circle/hallow. Won’t be using again because I didn’t like the puffiness but I think it’s worth a try with the right application. If you are irritation and acne prone I wouldn’t go for this. It is an oil base and while it’s a thinner oil it still slides around the skin and can get places you don’t want. And to add some context I used this for about 2 weeks for me to see the noticeable difference. Everything prior to that could be placebo. Research online says it should take about a month but as I said, puffiness that was minor became voluminous and noticeable. Wish it was able to stay only where I put it!

    SUPER OILY Consistency
    If you're an oily girl like me, use with caution. This is SUPER oily. When I read serum in the product name, I thought of a gel like serum, not an oil. It is super greasy, so you may want to save this for nighttime skincare. It's too soon to see results but I at least wanted to send out a warning about how oily/greasy it is for my oily friends. If you have drier skin, you may love the super charged shine this lends. I make this kind of shine on my own and don't need more help in that area. Will definitely switch to nighttime use vs daytime.
