A great polish

This is a lovely shade, and I'm surprised by how well the colour shift occurs. When cold, its a dark grape.
When warm, mine doesn't shift to a magenta pink like you see in BSG's picture, but instead, a dusty mauvey pink. Its still a dramatic change, and it is beautiful. Natural nails feel strong, and product has does not easily chip. Fully opaque in 2 coats.


I ordered this gel back in August 2020 (7 months ago now) and finally got around to trying it today. I’m pretty disappointed with the formula. It’s extremely think and stringy. I did 2 layers and the polish is so thick that I’ll probably end up removing it from the one nail that I used it on, as it looks a bit strange. It hasn’t been opened and all of my gels and polishes are stored upright in a dry place which is not exposed to sunlight. I’ve never had issues with any of my other BSW gels and I also used “Neptune” Phases Gel for my manicure and the formula is great. I tested the colour changing and it’s just “meh” for both polishes. I probably won’t try any other colour changing gels, I’ll just stick to the regular gels. It’s too bad, the colours on the website look like they could be amazing, but unfortunately for me, they just aren’t great.

Hi Heather,

Thank you for taking the time to leave a review for #P10 I'm Really A Mermaid.

We apologize the product was not as expected.
Rest assured, we are here to troubleshoot and solve any issue together.

Please note these steps that may help to achieve a smoother application for any thicker gel products received:

1.Carefully place the tightly closed bottle into a bowl of hot - warm water for 15 minutes
2. After this, carefully remove from water and shake/roll the bottle very well upside down for 30-60 seconds
3. Apply in a thin and even coat

However, from your photos, we can see this bottle may be a possible defect.
In which case, we will be in contact directly with an exchange for you!

We look forward to speaking with you soon.

Thank you.

Best regards,

I'm Really A Mermaid

Love both shades tons of sparkle

Extremely thick

This particular color was very thick and goopy and stringy and hard to work with. I reached out to customer service and they attested all gels with hexagonal glitter is thick and goopy, which i disagree with. Love the effect, hate the texture.

Cute but nothing extra special

It is a unique idea and very intriguing, however the colours didn't turn out as nice as I anticipated. The pink is very sheer. I put on an excessive amount of layers because I kept expecting a nicer colour. However, I wouldn't recommend against it. It is still a nice nail polish.
