The CND Shellac Gel Polish – What’s Old Is Blue Again (7.3ml) is a professional UV/LED gel polish designed to deliver long-lasting colour, mirror-like shine, and salon-quality performance. Part of the Upcycle Chic collection, this shade is a striking azure blue that brings a fresh, modern twist to classic blue tones—bold yet wearable for both everyday and statement manicures.

Formulated with CND’s original Power Polish system, it combines the ease of traditional nail polish with the durability of gel technology. The result is a smooth, even application that cures instantly under a UV or LED lamp and provides up to 14 days (or longer) of chip-resistant wear without dulling or peeling.
