A precision nail gel that smooths thick, ridged nails
SVR Xérial 40 Nail Gel is a targeted gel for damaged, thickened or ridged nails on the hands and feet. It is built on SVR’s patented complex of 40% pure urea and amino acids, which exfoliates and hydrates the nail at the same time, so the surface becomes smoother and less thick. Salicylic acid refines the nail plate further, while piroctone olamine helps purify the nail environment and keep fungal flora in check. SVR reports that 100% of users saw reduced nail thickness and 95% found their nails smoother after regular use.
The texture
A clear, fragrance-free gel applied with a fine brush built into the tube, so it goes exactly where you need it. Its precise tip keeps the gel on the nail and off the surrounding skin.
Who it suits
- Thick, hard toenails that are difficult to cut
- Ridged, rough or uneven fingernails
- Nails damaged by friction, shoes or sport
- Adults, children over 3, and pregnant or breastfeeding women
Worth knowing before you buy: Results build up over weeks, since nails grow slowly. Apply only on the nail: the high urea content can sting cracked or irritated skin around it. For rough heels, choose Xérial 50 Extreme or the Nutri-Repairing Feet Cream instead.
How long one tube lasts
Used morning and evening on a few nails, the 10ml tube lasts around two months.
