Although results will vary by individual, most users see noticeable improvement results within 2-3 weeks. Others with darker skin pigment may have to wait for 4-6 weeks. If no sign of improvement after 8-12 weeks, then you might want to seek a more specialised product. By “specialised product” we mean a prescription strength skin lightener).
