Promising Skincare Product with Clean Ingredients
I have always loved this brand and have purchased many of their skincare products in the past, so I was excited to try their Volufiline after seeing how popular it has become on TikTok. A lot of people online claim it helps plump the skin and reduce the appearance of fine lines and wrinkles without needing injections, which definitely caught my attention. For the price, I think it is a pretty reasonable product if it actually delivers results. From what I understand, this is not a product that gives instant results and it can take at least three months or longer of consistent use before you really notice a difference. Because of that, I cannot honestly say yet whether it works or not, but I plan to continue using it and will update my review over time if I start seeing visible changes. I also purchased a separate roller ball attachment for the bottle because it makes application much easier and more precise. Without the roller attachment, you would mostly be applying the product with your fingers, which can apparently cause your fingers themselves to become plumper from repeated contact. As always, one of the things I appreciate most about this brand is the transparency and focus on clean ingredients. Their products always feel thoughtfully formulated, and I like knowing exactly what I am putting on my skin. Overall, I am hopeful about this product and excited to see the long-term results.

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
