Ingredients & Cautions

This product contains HEMA, do not use on those with a HEMA or acrylate sensitivity.

Always wear non permeable, nitrile gloves when handling any UV gel product.

Only apply to healthy nails.

Avoid all contact with skin. If contact with skin occurs, remove immediately.

Do not cure nails with product on the skin.

Use a 36W UV/LED lamp with a minimum of 365 + 405 nanometers to cure. Cure for 99 seconds in low heat mode to prevent heat spikes. If hands are removed from the lamp during curing, always make up lost seconds with another round of curing. It is not possible to over cure this product.

Remove gloves using a 'no touch method' i.e. do not pull from the fingertips where you could touch transferred product, pull down from the wrist, turning the glove inside out and dispose of in general waste. Always use a fresh pair of gloves for each client.

Always wash both yours and your client's hands with warm, soapy water after the final application of top coat and before any hand creams or cuticle oils are applied

Customer Reviews

OMG! Gorgeous and I am a convert!

I usually cannot be bothered to write reviews, but I wanted to reach out to you and say: WOW!

I have been buying other brands Bluesky, Mylee and others for many years and came across Twenty not so long ago. I was discouraged by the much higher price and as I quickly get bored, I did not want to invest that much in a single bottle.

However, your white milky varnish with sparkles convinced me and… my first application was a huge failure! I wanted to use it the same way I use other brands and varnish was far too thick and I did not like it. I felt disheartened and put the bottle away for a few months and was completely not impressed with all the reviews.

I recently bought your shimmery builder as my nails are burnt after using one of Mylee's holo varnishes. I decided to give another go but this time I read your instructions and watched videos and followed recommendations about using different brushes.

OMG – your builder is amazing, and application is a dream (with a right brush). Peach colour with shimmers is gorgeous and so natural – I am in love, and I will be buying more colours from your collection. I love shimmering everything and cannot wait to get all colours (please restock - Charisma!!!!)

Obsessed with this shade

This is the perfect subtle shimmering builder gel! Not only it applies a dream but the colour is beautiful alongside the gold shimmer!

Strong and Beautiful

This gel is durable, beautiful colour and perfect from an every day nude mani.


I love this shade because it’s so subtle but really pretty in the light. Lasts 3 weeks. Will buy again.


I am absolutely in LOVE with everything about this brand. The products, the aesthetic, the customer service. Outstanding ⭐⭐⭐⭐⭐
