Hi there, can anyone offer some advice on treatment for my knees. I have brown marks on them which are making me miserable and really self conscious. People have commented on them and now I'm anxious to wear anything where they are on show. I've tried various moisturisers / using a pumice stone to exfoliate, but to no avail. I'm very fair in skin tone so it's quite obvious. Any advice very much welcome 🙏
