COSME DECORTE Repair Nail Serum, 7ml

I dab a little on my cuticles and rub it in, and it quickly penetrates, leaving my skin feeling dry. It's virtually odorless, so it doesn't mix with the scent of my hand cream, making it extremely easy to use. It disappears like alcohol evaporates, but it doesn't disappear immediately after application; it's a strange liquid that only penetrates once you rub it in. If you don't rub it in, the water droplets stay on your nails. When I first used it, I applied it to my nails like nail polish, and I was worried it wouldn't dry at all. Unlike nail oil, it's not greasy or scratchy, and there's almost no strange feeling like wanting to wash your hands after application, which I personally find very pleasing. I think I could use it every day. I haven't noticed any major changes so far, but I do feel like my fingertips are smooth and clean. The packaging is elegant and lovely. It would make a great gift! Thank you, CosDeco, for making such a great product!

I purchased this product in June 2025. I'm troubled by vertical lines on my fingernails and the dryness that causes them to quickly turn yellow as they grow out. I used to have a Muji pen-type nail oil, but the oil remains on the surface of my skin, so I couldn't use it during the day. While it's fine if I could apply it at night and go to bed, I often found myself needing something and having to get up and wash the oil off right away, which made me feel like I wasn't getting the full benefits. I discovered this product when the Décolleté Nails line was renewed, and honestly, I was hesitant to buy it because it seemed expensive. However, I wanted to keep my natural nails looking beautiful, and I thought this would be a better fit for me than buying a bunch of nail enamels, which I only use occasionally, so I decided to buy it. It's an odorless, smooth liquid. Be careful not to run it off if you don't hold your nails level. I massaged it into the base of my nails. It absorbed surprisingly quickly and wasn't sticky. The day after applying it, I noticed a slight change in the surface texture of my nails compared to when they weren't polished. (My nails are usually opaque like frosted glass, but they've become a little more transparent.) It may be within the margin of error, but the vertical lines seem to have thinned as well. It's small, so it's great to carry around and use during your breaks at work or to refresh yourself. I'm not an expert on the nail industry, but I don't think it's the kind of product I'd buy for myself, so it would make a good gift.

It's not sticky and can be spread quickly even with a small amount, making it very easy to use. The packaging is lovely, so you'll want to keep it close at hand.

It's not sticky and is very good.
