I was listening to a dermatologist & skin expert on the radio recently and the presenter asked her to recommend a reasonably priced product for sufferers of spots, that could be purchased in a supermarket, high street chemist, etc. She said that the product should include the ingredient salicylic and would recommend Neutrogena Spot Stress Control facial scrub. So, as a spot sufferer for more years than I care to remember, especially on my chin, i went & bought said product and by jove, it bloody well works. I started using it a month ago and within the first week of use all my spots were gone and not one since. I'm in shock. It hasn't made me look beautiful and younger looking, I'm 50, but I'm really delighted with finally having no spots!
I know that everyone's skin is different, and what works for one may not work for another, but I just wanted to share this recommendation and maybe it'll help someone else.
