Thank you for your enquiry. I highly recommend that you get yourself on to a very specific skin care regime. You need a good cleanser that will encourage your skin to gently resurface on an ongoing basis (EG one of the Neostrata or Nimue cleansers). You should be using potent anti-oxidants in your day products (EG: A cream form Lamelle’s Nourish Range or one of the Skin Ceuticals Anti-Oxidant serums), and then at night, something high in retinol (EG: Skin Ceuticals Retinol 0.3 or Skin Medica’s Retinol Complex or Lamelle’s Evening Glow). This product combination, will most definitely even out your skin and prevent further dark marks, work on the existing darkened areas and get your skin looking radiant. You do not need to purchase everything at once, you can slowly introduce one product a month until you get yourself on to everything you need.
