Why is using a base coat important?
For starters, using a base coat can improve the longevity of your polish. It contains elasticity that makes the nail polish more durable as your nails bend and also provides an extra dose of 'stickiness'. They can also prevent your polish from staining your nails. This is especially beneficial if you prefer to use dark colours. Some base coats (though not all) can even help improve your nail health, such as helping to strengthen your nails.
