Ever noticed that your nails have a yellowish tinge after you remove your favourite shade of polish? Unfortunately it's true that nail polish can turn your nails yellow. Why, you may wonder? There are a couple of causes, but the most common one lies in the colourant within the nail polish formulation.
The colourant in dark nail varnish goes through a chemical reaction with your nail plate when the two meet, and can result in a yellow stain. The problem, however, is that the reaction is totally unpredictable- it won’t happen for every dark nail polish, nor will everyone who uses the polish experience the same discolouring. Another possibility? Many nail varnishes contain the chemical formaldehyde, which reacts with keratin proteins (found in our nails). The result? Brittle, yellow nails.
But luckily for us it's not all doom and gloom, as a couple of easy precautions can avoid the discolouration (and make your varnish last longer too!). Firstly- and we can’t stress this enough- always apply a clear base coat to your nails before your colour coat. This forms a protective barrier, which prevents the colourant from staining your nails. Plus it's great for prolonging your manicure's life cycle (provided you finish off with a clear top coat too. It makes removal so much easier). We love Sally Hansen Diamond Shine Base & Top Coat for multifunctional nail care.
Though it's not scientifically proven, many people swear by the power of lemon juice, and have noticed that rubbing half a lemon on their stained nails dramatically reduces yellowness. The juice is said to act as a bleaching agent, restoring nails to their natural pink shade.
Still no luck? Then it might be best to avoid dark shades of varnish altogether. Reds and browns are especially notorious, so take extra care when working with those and flaunt your favourite pastel and nudes!
