Why do I need a top coat?
So you’ve painted your nails in an amazing colour... is that your mani done? What’s this top coat thing, and why do you need to add yet another coat? A final layer of clear top coat over your finished manicure is important for a few reasons:
Finish - Some nail polish shades dry matte - neon colours, for example, are notorious for this. Most top coats will restore shine. On the other hand, sometimes you'd prefer a matte finish, and a matte top coat can give the desired effect.
Evening out brush strokes - Some top coats are great for smoothing out uneven application and visible brush strokes, to give a professional finish to your mani. These will sometimes blur your nail art though if you’re not careful (and sometimes even if you are).
Rapid drying - Top coats can speed up the dry time of your polish. Unfortunately, many quick-dry top coats are also prone to chipping, and shrinkage (where the top coat makes the colour recede from the edges of the nail) is more common with quick-dry top coats.
Prolonging your mani - A top coat (along with a good base coat) can help prevent chipping of your manicure. Additionally, tip wear (where polish wears off at the tip and bare nail starts showing) can be slowed down by reapplying top coat every few days.
Hardens nails - Adding a hard layer of top coat can strengthen the nail and prevent breakage.
Smoothing out glitter - Glitter polishes can often leave a bumpy finish. Adding a thick layer of top coat can make it smooth and glossy, and some top coats are especially made for this purpose.
Overall, investing in a good top coat can save some of the polishes you previously thought were unwearable, and extend the life of your precious, time-consuming manicure!
