I too have suffered with acne issues and I found that the best method was a 2-week clay mask bootcamp by Veronica Gorgeois.

How I did it:
I applied a clay mask every day for two weeks
* Let it sit on your skin for 15 minutes or more until the clay has dried up. (It will look similar to dry cement)
* Use a damp wash cloth to help remove the mask
I used:
- Bentonite clay (you can buy the clay online with this link) ( goo.gl/yH6URa )
How to make:
- 1 Tea spoon of apple cider vinegar
- 1 Table spoon of bentonite clay
- Water
* add water little by little to achieve a paste consistency
* if it is too runny it will not apply well on your skin - add more clay to the mixture to thicken it
I also drank 2 - 3 litres of water daily; and ate a diet rich in raw vegetables to aid the process.
