The innovative nail polish system All Week Long has a special daylight-formulation - for up to 7 days perfectly polished nails. This system functions in 2 phases: ALL WEEK LONG NAIL POLISH + ALL WEEK LONG TOP COAT. A base coat is not necessary. The special ALL WEEK LONG TOP COAT dries through natural daylight and protects nail polish from chipping. Over time the ALL WEEK LONG TOP COAT strengthens the nail polish due to a reaction with natural daylight. The polish appears glossy, perfect and colour intensive up to 7 days. Change the colour of your nails according to your mood!
