Fabulous

I've tried so many nail products and none lasted more than a day before they would start to chip and show wear. This is the first to really impress me with its long wear and great protection against breaking.

Loving the Londontown products!

I chose to give my nails a break during lockdown and only used oils to moisturize and treat my nails. Now I am ready to start using products again and purchased the Nail Treatment, Nail Hardener, 2 shades of polish and the clear Gel Top Coat. I'm loving all of them. My nails are healthy and strong, and the polish is beautiful.

MY GO-TO FAVORITE BASE COAT

I have been using this base coat for years and it is my go-to favorite. Love how it coats and protects my nails, which I really need since I have nail psoriasis, which results in fragile, peeling, easily broken fingernails. It is my only base coat choice after years of using other base coats. Easily outperforms Chanel, YSL and other premium brands, this will be part of my manicure kit for years to come.

Brittle no more

I just started using this product to help with my nails that have been splitting up the middle. I'm hopeful this will prevent the splitting.
