Dear folks I want to share my happiness with you. I cure my stubborn face SD with mixture of pure aloe-vera and himalayan salt. Just add table spoon of salt and little destil water to 2 dl aloe gel. Let shake it and give some time to dissolve. Wash your face with soap and apply gel on skin and give couple min massage. I did it every evening and after 7 days you should see a big difference. In a couple of weeks gone.
