Rubber base is a type of flexible and durable nail base used in nail extension and strengthening techniques. It has a thicker texture than a classic base for gel polish, is elastic and impact-resistant, making it ideal for strengthening weak and brittle nails.
It can be transparent or coloured, and thanks to its structure, it allows for a slight nail extension of a few millimeters, as well as filling in irregularities and unevenness on the nail plate. The name comes from its rubber-like, elastic texture, which absorbs impact, making the base both strong and flexible.
It is used to strengthen short and medium-length nails and is suitable for all nail types, especially those prone to breakage.
