From nail strengtheners to rapid-dry nail polish and stick-on nails, now is a smart time to shop for serious savings across some of OPI’s most in-demand ranges.
OPI have launched their 45th Birthday Bash sale, a rare opportunity to upgrade your entire nail routine for a fraction of the usual price. And among the bestsellers is the Repair Mode™ Bond Building Nail Serum - which is said to work wonders in weeks.
Credited with reforming biters and gel addicts' talons, with fans saying their 'nails are the strongest they've ever been', the frequently sold-out bottle is now back in stock and reduced to just £20.30.
The OPI 45th Birthday Bash sale is a great time to try the brand's bestselling Repair Mode™ Bond Building Nail Serum.
A first-of-its-kind product, it has a Patented Ulti-Plex Technology™ that penetrates the nail surface, for repair that starts from within.
Hailed by beauty lovers as a 'wonder' product with many claiming their 'nails are the strongest they've ever been', the fast-drying, easy-to-apply formula promises to deliver significantly stronger, shinier and healthier nails in just six days with regular use.
OPI’s 45th Birthday Bash sale has landed, and shoppers are wasting no time filling their baskets with bestsellers
If your nails snag and chip easily, then it's the perfect time to follow in scores of shoppers' nail journeys and follow their recommendation of the OPI Repair Mode. And now with 30 per cent off, thanks to the OPI 45th Birthday Bash sale.
The OPI Repair Mode™ is here to reverse some of the damage caused by years of gel manicures, nervous biting and picking.
You might have heard of bond-building shampoos and conditioners, but OPI has taken the same technology to help build new bonds from within the nails for smoother, stronger talons.
Going further than bog-standard nail strengtheners, the twice-daily serum helps to repair nail keratin structure by penetrating the surface to build new bonds inside the natural nail. When used twice a day on bare nails for six days, it has been proven to repair 99 per cent of nail keratin, resulting in smoother, stronger nails.
A fan favourite, brittle nails recommend the nail serum time and time again, so much so that the serum has sold out twice, with one sold every six minutes.
With 30 per cent off, it's a great time to invest in your nails ahead of the spring and summer. And, if you're looking for a new glossy, long-lasting manicure, then there's plenty to entice you further with savings on the bestselling OPI Infinite Shine and RapiDry 60 Second Drying Polishes.
The TikTok-viral OPI Press-On Nails are also on sale, with users claiming they last far longer than expected and rival salon results, so these could be a great way to save on the expense of salon bookings.
