Care & Use

very strong and fast drying base coat, made my nails last multiple days without budging or noticable chips.
This base coat is seeming to help my nails last quite well, but was a bit weird applying to nails. Got a bit sticky and uneven but doesn’t seem to be a problem since they are still lasting!
My fave base coat to date.
so fast, love my free gift so pretty
I find that this base coat works very well hanging onto the nail and gives a nice smooth beginning for the polish
This base coat is fantastic! I work on boats and get my hands wet all day but my manis have been lasting 5 days when previously they would only last for 1 - 3 days. I will definitely order more when it runs out and Im keen to try the ridge filling base coat too to put under more sheer polishes!
Super Smooth has been a real hit for me – long-wearing and helpfully blurring. (Extra Strong didn't seem to vibe with my nails, but it's worth trying both to see which you like.) Thanks, Cosmic!
Every mani I use the super smooth base over the Extra Strong base. This ensures my mani lasts, and all the ridges I now have on my mani’s are always super smooth, no ridges visible at all. I love this duo.
I always use a base coat,I love this one because I have found it helps my mani last longer, the Extra Strong lives up to its name . I have found it to be better than other base coats. Highly recommend!
I love using the extra strong base coat. I used to have a lot of breakage and snaps but with this base coat I seem to be able to maintain lovely long nails
I needed to find a base coat without PVB and this is wonderful! My nails are recovering and I'm really happy with the longevity of my manicures
Love this base coat! It's now my go-to. Super easy to apply. It dulls the yellowing of my nails, dries quickly and smoothes ridges. Never have a problem with my mani not lasting the week esp when paired with a top coat!
A really fantastic smoothing base coat that dries quickly and sorts my ridged nails right out. Awesome value too. I have another ridge smoothing base from another brand and it doesn’t compare in any way. Will be sticking with this one now.
I got this as a freebie in a recent order and I am pleasantly surprised. This is the ultimate base for longer-lasting manis with minimal chipping. Will have to repurchase once I run out
I’ve found the smoothing base coat to be really long lasting! I had trouble with the extra strong base coat, but the customer service at Cosmic Polish has been incredible.
This base is a must have. It seems to have ridge filler because my nails are all seamless after I've applied the base. It dries super fast which is a bonus
Bethany threw in a free Extra Strong base for me when I was missing a polish in my order, I wasn't expecting that so thank you for the amazing service! This basecoat has been a complete gamechanger for me, I always experience some chipping after a couple days at work as I'm an optical dispenser and always repairing glasses. I had just accepted my fate somewhat, I work with my hands so there isn't much getting around it but my polish actually held up all week using this basecoat with only some minimal chipping! I've tried it out now for a few weeks and I am always getting a full week of wear before any small chips appear, previously it was only a couple of days. I guess it's also working really well with my body chemistry, because no other basecoat as worked for me this well. It is excellent, thank you again Bethany!
Absolutely love it, have a few pits an dents in my nails and wit worked perfectly to fill them so my polish looks smooth as a baby’s bottom 😂
Using the extra strong base coat I have had my most recent mani last twice as long as is normal for me when I use other brand base coats, absolutely delivers on what it promises. I'm obsessed!
Really easy to apply, excellent foundation for their lovely colours! Thanks :)
Like the slight tint so you don't mix it up with the top coat.
Dries quickly, does the job
Such a smooth base for the polish which made it last so much longer than I expected!
Nice colours.
Don't last a week though.
Political Bias of the company towards a minority left me wondering why as it's nail polish not government department.
Will not purchase again for that reason.
Regardless of the reply, I'm a customer buying nail polish. Political bias does not need to be part of the company agenda, but if you wish to limit your customer base, you go for it. It won't help your sales any.
We're proud of our support of all minorities and standing up for what's right, as we are a small business and have every right to do so. Thank you so much for your order though and I'm glad you liked the colours :)
Easy to apply and super quick to dry.
Really helped to make my colour last a lot longer 😊
This does exactly as promised, smooths out ridges and grooves on my nail bed for a perfect base. So impressed with this product!
Bonus it dries quickly!
perfect base coat under any Cosmic Polish
This is amazing. Love how smooth it makes the nails
This is amazing, really smooths out all the ridges and gives a great, even base
This has become my favourite basecoat. It dries quickly, helps my polish apply smoothly and I've noticed since using it my polish is lasting a day or two longer before chipping. Will definitely be stocking up 😂
