I have been using Fruit of the Earth's Aloe Vera Gel (the clear gel)with great success. You can get a big bottle of it for $5 at Target or Walmart or any other drugstore. I have been applying it to my skin twice morning and evening, and it has given me amazing results. It does a great job of healing Acne and smoothing skin and it is very cheap!!
Of course I also avoid sodas and eat well, etc. However after wasting money on so many expensive products it is nice to find an inexpensive product that delivers results.
