Good skincare. Just okay for wrinkles and fine lines
I’m not sure it’s filling in wrinkles but it’s not hurting either. I kind of think once your a certain age there isn’t a lot of change that happens with surface level products. It’s kind of more about slowing the aging process versus reversing it. Reversing may only happen in a surgeons office or by treatment from a medical esthetician. That being said I do think this product is offering me support by slowing down the aging process and reducing new lines and wrinkles. My skin definitely has a dewy appearance after using this product. The product is lightweight and goes on like a light oil. It is a tad greasy when it’s first applied but it does absorb well. I try to put this on when I have time to let it absorb a little but I have also been in a rush and had to go straight into makeup application after using. I didn’t have any issues with the quick transition. As with most of the Ordinary line the prices are economical for skincare. I give this 4 stars only because I didn’t really see a change/improvement in my current fine lines and wrinkles. I do think overall it’s offering some benefits. The bottle is small but the amount needed per application is small. You have to shake the product out of a little restricter cap which is kind of annoying. I think a tiny dropper would make for better dispensing and less waste. As with all my facial serums and skincare products, I always rub any remaining product on the tops of my hands.

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!
