Words From Our Community
Honest reviews from skincare lovers around the globe.
I purchased this product because I was suffering from severe split and cracked nails. It comes in a tube, so I can use it anytime, anywhere, just like hand cream. The tapered end of the tube makes it easy to adjust the amount. The pleasant scent of essential oils is soothing every time I massage my nails in. I used to use uka's nail serum, but the brush-type bottle was too hard to carry around, and I couldn't keep up with nighttime care. This time, I'm aiming for strong, healthy nails.
I love this! It's light, but still feels moisturizing. I think it's perfect for daytime use. The scent is unique, but not too strong, so I think it's fine to use before or after meals! It's so comfortable to use, I plan to buy it again!

Some portable nail oils are as small as 2mm, but I bought Osaji because it's 10g. It's suddenly starting to feel like autumn, and my fingertips are starting to feel dry, which is a sign of the season. After applying the serum around the nails and the rest to the entire nail, I followed up with hand cream, and the whiteness of my nails disappeared and they became shiny. I carry it with me and use it every time I wash my hands. The tip is thin, so it's easy to apply directly. I use Uka's nail oil before bed and Osaji during the day. Just a little effort makes a huge difference to my fingertips.
P.S. My nails have gotten significantly harder and healthier. They feel harder when I touch them, which makes housework easier and makes shampooing safer! I feel more secure. (Review 1) I quite like Osaji's products. The scent and effectiveness are nice. This time I used the nail serum. My nails are thin, weak, and small, so they require more care than most. I haven't used gel nail polish in a while, but when I went to the salon once last year, even the gel polish came off within a week, leaving my nails so damaged. Since then, even when I do my own manicure, it peels off in sections, so I have to remove it with remover every other day and reapply. My nail condition has gotten worse. Lately, I've been using Muji remover and removing it less frequently. I've been focusing on nail care, thoroughly practicing the following routine: lotion → this → nail oil → hand cream. Before applying clear nail polish, I apply this serum and then blot with tissue before applying the other. It definitely helps the polish stick better! However, the serum seems to contain oil, so it's important to blot it. This has gotten long, but this serum is very gentle and has a nice scent. It also removes the lines on my nails, so I think it really moisturizes. Serums are for those with weak nails, and they help keep them healthy. Oils are supposed to moisturize. I bought this after researching online, and I've been using both the serum and the oil. So far, I've had a good experience with the serum. I'll continue using it and add anything I can. Personally, I like the scent, too. It's a lovely, relaxing scent. Osaji is more expensive than department store brands, but less well-known than luxury brands. However, it's not inferior to those. I'd love to see more recognition.
