Updating the classic French manicure with an icy blue micro tip offers a subtle pop of cool color while preserving a clean, minimal silhouette. Prepare the nails with a sheer nude or translucent pink background polish to unify the nail bed color. Select an opaque, creamy icy blue shade for the tip line. Using a fine-liner detail brush with minimal polish, paint a delicate, razor-thin line along the curve of the free edge, keeping the line under one millimeter wide to avoid shortening the appearance of the nail bed. Alternatively, press the tip gently into a silicone nail stamper coated with icy blue polish for an instant micro line. Finish with a glossy top coat to lock in the clean design.
