Rubber Base Color (or « base colorée en caoutchouc ») is a very popular product in the world of manicure, particularly for the coating and application of à semi-permanent nails. What is it exactly? It's a nail base that differs from traditional bases in that it's thicker and more flexible, hence its name rubber. It is also coloured, which means that it is used as both a base and a colour. What is it used for? Rubber Base Color is an all-in-one product that offers several benefits: * Reinforcement of the natural nail: thanks to its thick, rubbery texture, it forms a protective, long-lasting layer on the nails, ideal for soft, thin, brittle or fragile nails. It prevents them from bending or breaking easily. * Corrects imperfections: its consistency smoothes the nail surface and fills in streaks or irregularities, for a perfectly uniform result and an aesthetically pleasing apex. * Optimum adhesion: it ensures excellent adhesion of the semi-permanent varnish, which lasts longer and peels less quickly. * Saves time: as the product is already coloured, it replaces the transparent base and the first coat of colour, speeding up application. * Mini extensions: thanks to its texture, it is sometimes possible to apply small extensions to the natural nail (a few millimetres) using a template. * Flexibility: it follows the natural movements of the nail without cracking, which is a considerable advantage over some harder bases. What colours are available? Rubber Base Color is available in a wide range of colours. The most popular colours are often natural and discreet, perfect for a nude look or as a base for a French or baby boomer manicure: * Nude and beige (pink, light, dark) * Pink (powdery, milky, candy) * White (milky, covering) * Transparent (although not colourfast, it's a widely used base) However, many brands also offer Rubber Base Colors in other colours;However, many brands also offer Rubber Base Colors in brighter colours (blue, green, purple, red) or with effects (glitter) for those who like a bolder manicure while taking advantage of its fortifying properties.In short, Rubber Base Color is a versatile product that strengthens, beautifies and protects nails while adding a touch of colour.
