I was hesitant to spend more money on a cuticle product, but the Cuticle Conditioner Serum is worth every penny. It not only moisturizes and nourishes my cuticles, but it also helps protect my nails from bacteria and contaminants. I love that it's a serum rather than an oil, so it doesn't leave any residue or mess. This is a must-have product for anyone who wants healthier nails.

As someone who struggles with weak and brittle nails, I have tried countless products over the years. The Cuticle Conditioner Serum is by far the best one I've found. It nourishes and strengthens my nails from the inside out, and the Onsen Hot Spring Minerals blend™ makes all the difference. I can't recommend this product enough!

    Skin Profile

    The Nail & Cuticle Conditioner Serum is a nourishing treatment designed to restore dry, damaged cuticles and nails. Enriched with Jojoba Oil, Vitamin E, Aloe Vera, and Shea Butter, this serum deeply hydrates and strengthens your nails. The formula is enhanced with Wakame Seaweed and White Pagoda Extract, known for their rejuvenating properties. With regular use, this serum promotes healthier nails, faster growth, and stronger, more resilient cuticles. Non-greasy and suitable for all skin types, perfect for daily use.

    How to use
    1. Cleanse & Prep: Wash your hands and nails thoroughly, ensuring they are dry before application.

    3. Massage: Gently massage the serum into your cuticles and nail bed using circular motions.

    ✨ Pro Tip: For best results, use at least twice a day to maintain soft, hydrated cuticles and strong, healthy nails.

    Best cuticle serum

    My coworker told me about this and I’m so happy she did. I’m on my THIRD tube! As a nurse my hands get so dry from using sanitizers and my nails get brittle easily. This serum helps a lot. I keep one in my bag and one in my car! Even my husband uses it! It’s an essential for your day to day routine.

    Helps with Hangnails and Keeps My Cuticles Moisturized!

    I've been using this cuticle conditioner serum and it's really helped improve the look and feel of my cuticles. I usually get super dry cuticles, especially in the winter, and this has definitely cut down on hangnails. Even in the warmer months, I still need to keep my cuticles moisturized, and this does the trick. It’s easy to apply, soaks in nicely, and makes a noticeable difference. Definitely a must-have in my nail care routine—thanks, Onsen!

    Cuticle Saver!

    I got this for my son, who picks at his nails a lot because of ADHD. His cuticles were red, irritated, and really torn up. I started using this every other night, and after a couple of weeks—wow! His cuticles look so much better.

    I’ve also been using it on my own nails to keep them from drying out in the cold, and it works great. It absorbs fast, isn’t greasy, and actually helps heal. Honestly, 10/10. If you have dry or damaged cuticles, you need this!

    💅 A Must-Have for Press-On Nail Lovers!

    This cuticle cream has been saving my fingers! I wear a lot of press-ons, and the glue can be super drying. Lotion doesn’t always cut it, but this cream keeps my skin hydrated without feeling greasy. It has a nice lavender scent and, best of all, won’t loosen your nails like some other oils do. Plus, it works while you're still wearing your nails! The cap did come off, but honestly, who cares? This stuff is a lifesaver—definitely worth checking out!

    Flip or Flop
    Hydrated Nails on the Go

    Do dry nails and cuticles drive you crazy? If you live in a dry climate like me, you know the struggle! I saw this Onsen Cuticle Conditioner selling out on Flip and had to try it.

    Let’s start with the cons—honestly, just the scent. It smells a bit like baby lotion, but it’s mild and fades quickly. Now, the pros? It’s made with natural ingredients, deeply nourishes my cuticles (even after washing my hands!), and penetrates like an oil—without the greasy feel. Plus, a little goes a long way, and it’s compact enough to carry in your purse. Definitely a keeper!

    Love This Product!

    I have worn artificial nails for many years. I decided to take them off. I started using the nail reboot system and my nails are doing great. They look a lot healthier and I love knowing that I am saving money by using this product! My 1st picture was taken 2 days after I started using the product. The second picture is now. I wish they would make nail polish that isn’t damaging to your nails.

    Don't expect it to work in a couple of days
    I bought this because my nails are very weak. I am on a lot of medications and my nails start looking ok but they they split or snap off.
    I have had to move into a nursing home so no nail bar visits. The chinese ones don't come off and last for ages, knacker your nails. I have been putting this cream on my nail and under my nail for just over 2 weeks. I am just seeing improvement. My cuticles come off with no pushing and pulling. I have put a clear rimmel nail hardener over just to protect what I have. I must say it's brilliant. I would highly recommend and if the company want me to test anything I am up for that. I will pay and give my honest review. If your not sure just get the one, I got the twin pack because it worked out cheaper. I won't be running out that's for sure. I will take some photos tomorrow

    Went for a manicure that totally tore up my cuticles so I needed to do something to address it. Ordered this cream and within a week my cuticles were back to normal. Very soft fingers with no pealing cuticles now. See before and after photo which was 1 week apart before/after using 2x/day.

    This stuff is AMAZING

    My nails were terrible, I had started getting Builder nails because my nails were weak, breaking, flaking etc I thought due to being in the swimming pool most days, then before a holiday I used some gel nail remover from Temu and quite literally burned a hole through my nail - they bled! My daughter patched them up as best as she could for our holiday, and when I got home she carefully removed them and I started using an Opi nail strengthener and special top coat, used twice a day for 9 months, my nails grew back slowly but surely, but still flaking and sometimes ripping. I was looking for something new to try and this got rave reviews! Without a word of a lie NO MORE FLAKING, yes, the odd little sharp edge, but even though I keep forgetting to use it my nails are growing and have a shine!

    Sehr gute Pflege für Nägel nach Soft Gel Press Ons

    Ich habe den nail & cuticle conditioner nun schon zum zweiten Mal gekauft und bin sehr begeistert. Er lässt sich gut auftragen und zieht schnell ein. Zweiteres ist für mich das wichtigste Kriterium. Die Nägel sehen danach sehr gepflegt aus und sind weniger trocken und brüchig. Beim ersten Kauf habe ich das Nagelöl auch bestellt. Der Conditioner gefällt mir aber besser, da Öl naturgemäß immer etwas mehr fettet. Ich benutze häufig Soft Gel Press Ons, wodurch die Nägel zwischendurch regelmäßige Pflege brauchen. Mit diesem Serum ist das kein Problem mehr. Kann man wirklich empfehlen!

    Good product, bad packaging

    I’ve only used it a few days but after the first use, I was please with the way my nails and surrounding skin felt. My only complaint is the screw on top. WHY did they make it so it adds an inch to the overall size of the product, making it more difficult to fit into small makeup bags? Also the top is sooo slippery to turn after you’ve just put cream on the your fingers. I would seriously consider not re-buying this product again because of its packaging.

    Ahhhhhhmazing!

    I was skeptical because my nails looked so horrible I thought they were beyond repair. They were cracked and brittle. After the first use there was immediate improvement and my nails keep getting healthier. There’s a world of difference after only a week. Strongly recommend!

    Spendet zuverlässig Feuchtigkeit und pflegt trockene Nagelhaut

    Ich habe die Reparaturcreme verwendet, weil meine Nagelhaut häufig trocken war, und bei mir hat sie tatsächlich geholfen. Besonders positiv finde ich, dass die Nagelhaut nach der Anwendung gut mit Feuchtigkeit versorgt ist und sich deutlich gepflegter anfühlt. Bei regelmäßiger Nutzung hatte ich das Gefühl, dass die trockenen Stellen insgesamt besser wurden und die Haut nicht mehr so schnell spröde wirkte. Ich habe die Creme immer wieder im Alltag verwendet und war mit der Pflegewirkung sehr zufrieden. Gerade bei trockener Nagelhaut finde ich sie praktisch, weil sie die Haut zuverlässig mit Feuchtigkeit versorgt. Für mich erfüllt die Creme ihren Zweck sehr gut und ich würde sie wieder verwenden.

    Super nail cream

    A very light but effective nail cream. Moisturises well around the nails. Have purchased 2 or 3 and 1 for a gift which was well received.
