'Shake It' - @scoutcosmetics eco-luxe 5 Free breathable & water permeable formulation with a signature aromatherapy scent when dry. So, what does breathable mean? Well, many traditional nail polishes create an impermeable barrier between the nail and elements like water and air. With natural beauty in mind, Scout Cosmetics new breathable nail formulation is different. Thanks to a unique polymer, the new formulation allows nails to breathe by allowing oxygen and moisture molecules to freely pass through the nail polish layer even after multiple coats are applied without comprising on vibrancy, richness of colour and shine.
