I started using st ives products, and i was using them everyday, and now i have a dark ring around my neck. how do i get rid of it?

Stop use: A dark ring or hyper pigmentation maybe your body's response after it was irritated /allergic from/to the chemicals in these products. I would avoid these products. If its itchy, otc Hydrocortisone cm would help and the darkening will fade w time, avoidance if scratching, and avoidance of sunlight (use spf).

Stop St Ives: Most probably you are having a reaction to this skin product. This is very common and not usually a severe one. Stop using this and after a couple weeks or a month you might try a different product for your skin. If this does not clear or becomes worse you may need to see a skin specialist.
