Base coat format, ingredients and what the data lists

This is a liquid, brush-on base coat in a bottle, applied with the brand's pro-wide brush. The brush is the widest part of the story here: it is shaped to cover the nail in fewer strokes, which is where the smooth, even coverage comes from. The product data does not list a volume for this bottle, so check the pack for the exact size. What the data does confirm is the format (a brush-on lacquer base coat), the ingredients listed (vitamin A and vitamin E) and the vegan formulae claim.

Where this base coat fits in your nail routine

Think of it as the bridge between bare nails and colour. You clean and shape your nails, then brush on the base coat, then follow with your lacquer and a top coat. Because it is a fast-drying formulae, it does not add much waiting time between steps. Used this way, it helps nails look neat and well-groomed and gives your colour a smoother surface to sit on.

Does a base coat work under nail polish?

Yes. This product is a base coat, which means it is designed to be applied before your nail lacquer rather than worn on its own as a colour. The brand describes it as part of a three-step system, with up to 7 days of wear when the full system is used. The pro-wide brush is shaped to hug the nail for smooth, even coverage without streaking or bubbling, so the colour you layer over it sits on a tidier surface. If you usually skip a base layer, this is the step that goes first.

Pairing this base coat with cuticle oil and polish

If cuticle oil is part of your routine, it works best as a separate step from your polish layers, since oil and lacquer do not mix well. Keep the oil for the skin around the nail, and keep this base coat for the nail plate itself. A simple order is: preparation your nails, apply the base coat, then add your colour and top coat. The fast-drying, high-shine formulae is built to sit under nail lacquer, so it can be the first lacquer layer you reach for.
