MANILA, Philippines - Apply polish to your nails enough times without giving them a rest in between and you will end up with weak, brittle nails. However, those soy-based polishes come with much higher price tags than the regular ones formulated with formaldehyde. If you refuse to go polish-less this season (we can’t blame you), you can strengthen your nails with this handy new product: the Anny Keratin Power-To Go from Anny’s Care-To Go Express Nail Care line, which is ideal for weak, abused nails. Keratin improves and strengthens the nail structure, reducing the incidences of splitting and breaking.
