Some of these products are based on science and many of them are actually useful! I have personally used many of them and can recommend them based on the scientific evidence.
Many of the products listed are available in your area, although the best one to buy is probably the one with the highest cost and also the most proven. Some products are more expensive than others, but I have tried them and I believe them to be more effective. This is what I recommend. I have also provided an option for those who want to pay more but would rather get the more affordable product. The top three products are: 1) Soothing and Stress Relief Acne Treatment 2) Stress Management Program for Acne 3) Sleep Therapy For Acne, but you can also get this product at any drugstore . Here is a link to the complete list. The rest of the information is from my own experience, and may not be 100% accurate, but the more you read the more you may see the effect it has on you. Please be patient with me as I do my best to describe everything in as many words as possible. I hope this helps, and please leave comments with your experience.
