Here are 3 smashing ways butter LONDON HQ fancies wearing Mellow the Yellow Nail Brightening Treatment.
1. Sheer Glow

This revolutionary 2-in-1 nail formula has such a pearly opalescent colour that many on the butter LONDON team prefer letting Mellow the Yellow shine on its own. Plus, it’s handy when you’re short on time. You don’t have to choose to apply a nail care treatment or a nail lacquer. It’s a one-and-done, no-think nail hack for showcasing a polished manicure even when you’re in a rush.
2. Basecoat Beauty
Apply Mellow the Yellow as a base coat underneath your favourite Patent Shine 10X Nail Lacquer for an ethereal “glow from within” look. Whether you choose to paint the entire nail in opaque coverage or let the pearly pop shine through, rest assured your nails are being conditioned 24/7 to help brighten the appearance of nails for when the lacquer comes off.
3. French Tip Base

Daring enough to try a DIY French Tip for your at-home manicure? Our team sure is. Apply Mellow the Yellow as a base to your French Tip for a dazzling extra touch that catches the light.
