Skin Profile

The Advance Rescue Nail Kit is a complete repair system that strengthens weak nails, softens dry cuticles, and restores a healthy look to your hands. The Enzyme-Activated Conditioning Serum uses Japanese White Pagoda Enzymes with cold-pressed oils to hydrate, smooth, and reinforce brittle nails, making it suitable for recovery after gels or acrylics. The Reboot Oil blends Tsubaki, Tea Tree, Jojoba, and Rice Bran oils to penetrate deeply, reduce brittleness, and support resilient nail growth with natural shine. The Hand and Cuticle Rescue Cream combines mineral-rich Onsen Hot Springs Water, Shea Butter, Carnauba Wax, Jojoba, Squalane, and botanical oils to moisturize and protect dry skin without heaviness, while the professional tools in the kit refine nail edges, smooth ridges, and polish to a glossy finish for a clean, well-groomed look. Designed for all nail types, this system delivers lasting hydration, improved strength, and a healthier appearance with consistent daily use.

How to use
  1. Shape & Smooth: Begin with the Nail Reboot File (Grit 180/120) to shape your nails. File in one direction to help prevent splitting.
  2. Buff & Shine: Use the 4-Way Shining Buffer Block to improve nail health and appearance:

    Step 1: Smooth out ridges using the yellow side.
    Step 2: Refine the surface with the blue side.
    Step 3: Polish to a glossy finish with the white side.

    ✨ Replace buffing pads as needed to maintain consistent results.
  3. Condition with Serum: Dispense a small amount of the Nail & Cuticle Conditioner Serum onto nails and surrounding skin. Massage until fully absorbed.
  4. Reboot with Oil: Apply the Nail Reboot Oil to nails and cuticles. Massage gently in circles to support absorption and encourage nail resilience.
  5. Seal with Cream: Finish with the Hand & Cuticle Rescue Cream. Massage a pea-size amount into nails, cuticles, and dry patches on hands, elbows, or feet until fully absorbed.

✨ Pro Tip: Use the buffer once a week to maintain shine without over-buffing. Apply the serum and oil daily for hydration and strength. Apply the rescue cream at least twice daily or as needed to keep hands and cuticles soft.

Beautiful Packaging, Gorgeous Products

This is a really nice set of nail care products. The packaging is lovely and more than suitable as a gift. It’s a perfect little kit for anyone who wants healthier looking nails. The buffer has extra replacement pads which is very convenient in extending the life of the block. It gives my nails a natural shiny glow. The cuticle cream is quite light and absorbs easily. I adore the reboot oil - it smells delicious and has an easy to use rollerball applicator. My favourite is the hand & rescue cream which I apply just before bedtime. It makes my hands feel super soft. Information is included on how best to use the items. I’m happy these are vegan too! Recommended.

Everything you need to repair and rejuvenate your nails! Really works well!

There is so much to love about this complete set to rejuvenate and repair your nails!

There are two different serums (on a cream and other other an oil) to apply to your cuticles and nails. The cream feels so great and absorbs right in, the oil has a wonderful scent and feels so nourishing. I don’t really like the roller ball application, especially for the nails. I would be easier to apply a drop or two on each nail instead of rolling the oil and then spreading it over the cuticles and nails - but it does work and feels great!

The hand cream is light but very moisturizing and doesn’t leave your hands sticky in any way. My one criticism with this set is the jar the hand cream is in. It is so easy to screw the lid back on a little crookedly which them makes it really hard to get off again. You have to ensure the lid goes on strait or it will get stuck.

The bonus in this kit is the two files that come with it (one to file your nails and the other to polish and buff them to a shiny finish). The buffer set also comes with extra replacement pads.

I have been using this set almost daily on my damaged nails and they are looking and feeling great now.

I do find the price for the set quite high - I would have thought getting all the products in one set you would get a bit of a deal but it is nice to just order the set and have everything you need.

Would make for a nice gift set, but is a little expensive

This is a nice little kit of nail care items and is bundled in such a way that it would be a nice gift. The nail file and buffer are pretty standard nail care tools, nothing unusual about those or the refills for the buffer.

According to the little schedule printed on the container as well as on the pamphlet on the inside, you're supposed to use some combination of the cuticle oil, conditioner serum, and rescue cream twice a day. All of these are nice and smell fine, although the oil smells a little more sharp and not as floral as the serum and cream. I personally find myself reaching for the serum and oil more because they're less messy; I love hand/nail creams, but not so much when they're in a jar with a pop on/off lid since it's a little difficult to get it closed without getting the tin greasy. The oil and serum also absorb more quickly than the cream does, which stays fairly oily and greasy far longer so I end up picking the other 2 more often since I hate leaving fingerprints everywhere if I end up needing to do something with my hands.

At time of ordering, this set was priced at $49.95 and now at time of writing this review, it is listed at $44.99. Overall, it's a nice bundle of nail care items, but this seems a bit overpriced for everything inside. Maybe if any of these were spectacularly fantastic quality I would find this price range more reasonable, but they're not. Don't get me wrong, these are all nice enough, but they're nothing super fancy or particularly standout in quality compared to most other nail files, buffer boards, cuticle oils/serums, or hand creams I've used before.

Feels great, but does not smell great

This nail care kit is pretty nice. I like that it comes with instructions so you know how and when to use everything. The steps are very east to follow so that's a plus. When I got my nails filed down and buffed out, I really like how the cuticle cream and oil felt on my nails. They were both moisturizing and I used them together. The hand cream was nice as well. It's on the ticker side, which I liked because I have very dry hands and thicker creams absorb slower and last longer for me.
The only two downside I have are I did not like the smell of the items. Nothing is overly fragranced, but it did give off an earthy scent that I did not care for. I also wish the nail file was thicker because I found it to be very flimsy.

Restore life to your chapped hands and nails!

I have used the Onsen hand cream before and found it to be extremely smooth on the skin, but now with this nail kit, you are also targeting the nails. It is a multi step kit and they teach you how to use it - you first clean, trim and file your nails, then you use the buffer on it, which gives my nails a nice shine by buffing away the old keratin layers on the top - the buffer block is 4 way and there are replacement pads included. Then you use the conditioner serum, the reboot oil by gentle massage until absorbed into the nails, and a little bit goes a very long way. Then finish the whole thing off with the rescue hand cream, which is very smooth, I would recommend doing this at night and wearing cotton gloves overtop, and you'll have soft soft hands in the morning. This is a fairly comprehensive kit, especially for those who wear artificial nails or even nail polish all the time. When I want to take a break from these, I find my nails very ugly and damaged, so this is a great treatment for revitalizing them. The set is made in the USA and the 'secret' ingredient is Onsen hot springs water which is full of minerals (luckily, there is no chalky feeling which you might expect from the minerals). It is a very nice set, makes a wonderful and thoughtful gift!

Excellent!

I've gotten this onsen cream before so I know it is an excellent moisturizer. The rest of the package is of equal quality, the block for example is the perfect grade, really keeps your nails in shape. I especially love the inclusion of these "eco pads" which are for renewing the buffer block. If you've used blocks for a while you know they can get a bit meh and this is a really clever, thoughtful improvement. The cuticle oil is very good, it absorbs so well like jojoba oil but it has a nice smell to it as well.

Overall I'm very pleased with this set. It would make an excellent gift as well, the packaging is beautiful.

It has everything!

I’m not a person who has a lot of products and I do need to strengthen my nails so this was a no-brainer for me to try out. My initial impressions of the packaging are great and it’s not asking me to get more things to use the product which is big for me. I will use this for the next couple months and post an update at that time.

Easy to follow directions but you must keep up the maintenance which takes very little time.

I can see an improvement in just a few days. My nails and cuticles are very dry and cracked. Check back in a few months to see if improvement is permanent.

Really cool nail rescue kit

I really like this kit. Every time I do my nails, I make sure to use the buffing block to prep my nails with before applying my base coat. It really helps remove the last bit of cuticle stuck to my nail and helps prepare the surface of it. I love the cuticle and nail cream (blue tube). My cuticles actually look healthier which I was a little sceptical of before trying. The cuticle oil is alright. I find it a little hard to apply. The cream and nail file are average.

Deep Hydration for Professional-Level Recovery

The Onsen Secret Advance Rescue Nail Kit is a premium solution for those struggling with dry, brittle, or damaged nails, delivering a spa-quality experience through its high-performance blend of Tsubaki, Shea Butter, and Jojoba. This kit is celebrated for its exceptional moisturizing power, as the serum and cream work in tandem to deeply hydrate and transform rough texture into lasting softness. Both the oil and the rescue cream boast impressive absorbency, sinking quickly into the skin and nail bed without leaving a greasy residue, while the rich, creamy thickness of the hand cream provides a protective barrier that feels luxurious yet weightless. While it represents a higher investment, the value for money is evident in the professional results and the ease of application, with a mess-free design that makes it simple to integrate into your nightly routine for a complete nail and cuticle overhaul.

Good Value, Great Quality

Everything in the box is well made and works well. I love the nail and cuticle conditioning serum! It is saving my fingertips in our Canadian winter. The nail block is excellent quality - not too coarse and brings up a diamond shine. The hand cream does wonders overnight, too. It does have a very, very light rose fragrance which dissipates very quickly.
Two little quibbles which are. It worth knocking off a star:
I find the nail file a bit coarse for my tastes, but it will wear down eventually.
The metal roller on the cuticle oil is not practical. It doesn’t really work very well dispensing the oil and a bottle with dropper would have been more sensible.
Overall, it’s a lovely treat for myself and a great gift for friends.

Self care made easy

I can be super lazy caring for my nails and hands, so this one is a win since its an all in one care box.

I am actually really impressed with this nail care kit. The serum and oils absorb quickly and make my nails feel healthier and smoother after just a few uses. The cream is rich without feeling greasy and works well on my cuticles and hands. The tools included are actually useful and give a clean, polished finish at home. Overall, it feels like a full nail spa in one box.

I like it! Not greasy, cuticles moisturized.

Whether this is helping my nails grow remains to be seen, but it does help keep my nails and cuticles moisturized, which is important to me because I work in an environment that is very dry and cold (about 54° F daily) and my skin dries out quickly, so this Rescue Repair kit is useful for making sure my cuticles do not dry out and crack.

It has a pleasant scent, absorbs well and is not thick or pasty. It does not leave a long-lasting residue or oily feeling, either.

Overall, the cuticle moisturizing properties is enough for me to give it 5 stars alone.

A Complete Nail Rescue Kit That Feels Like a Mini Spa Session

This kit is impressively thorough with retty much everything you need to bring dry or brittle nails back to life. If you're just getting started in your nail care journey, or just want a collection of products that work well together, this is it. The serum absorbs quickly and feels incredibly light, but it packs enough hydration to make weak nails look healthier almost immediately. The reboot oil is the real star and worth the cost of the box. The blend of tsubaki, jojoba, and tea tree sinks in beautifully. With any nail product, its success is based on consistent use. While youll see immedaite results with the file and buffing block, stay on it and you'll have incredibly healthy nails with this.

The rescue cream is another standout. It’s compact but rich, and I love how fast it absorbs without leaving that greasy film behind. The included tools are surprisingly good quality espeially the the buffing block to get that polished, smooth salon finish.

Pros:
Complete system with oil, serum, cream, and tools
Serum absorbs fast and helps reinforce weak nails
Reboot oil deeply nourishes and softens brittleness
Cream moisturizes without leaving a greasy feel

Cons:
Requires consistent use to see the full results
Buffing block wears faster if used heavily

Robust set with plenty of high quality items for nail care

This is an excellent set to maintain your nails and cuticles. The rescue cream feels great on the skin and isn't sticky or greasy. The serum is very similar, but it's easier to apply precisely to your cuticles. I think my favourite part of the set is the oil though. It's rich, thick, and definitely keeps the dry cuticles a lot softer. I would order this set again when I run out.

Works well but kind of product over kill…

This is a nice nail kit, all of the products are high quality. You get a lot of product for your money, it’s a great value. When you start to read the directions you kind of wonder why there’s so many things in the kit. The directions are detailed and tell you which order to use everything in and even how to use the files. They say you can pick if you want to use the cream or oil or to alternate them. The nail file works well and isn’t damaging in the slightest. The buffer is great too and comes with a set of replacement pads. The oil and cuticle conditioner are very moisturizing and they don’t leave your skin oily. The rescue cream is phenomenal and really locks in moisture. All of the products are top notch and have really helped my hands and cuticles in this cold weather.

Great nail care set! Would make a wonderful gift.

I had previously gotten another Onsen kit that included everything in this pack but the nail buffer items - and I loved that kit! The products are definitely good quality and work well to keep my hands and cuticles soft and moisturized. The added bonus of the buffer and replaceable pads makes this set even better. That being said, if price is an issue, and the cost of this comprehensive set is too much, I'd highly recommend getting the 3-pc kit option and using your own (cheaper) nail buffer instead. The key products are really the cuticle oil (the rollerball applicator makes it so easy), serum, and balm. They're all travel ready, too! Great for keeping in your purse during colder months of the year so your hands don't dry out.

Yes for the nail care items - hand cream - meh.

I think strength of this kit is in the nail items (aside from the block). I have a similar block that I use that once you remove it and the hand cream, the kit becomes a better price point for the key items. I was looking for something to keep refresh my nails between gel coats, to help keep them strong and from breaking. I'm a few weeks in and the nails do feel stronger. The hand cream is nice, but its not very big, and I have another one I already like. As a gift, the complete kit is nice, but for myself the value is in the nail strengthening.
