Generally speaking, it is mostly a myth that diet affects acne
. It is much more likely that the acne breakouts are because of something else you are doing. For example, many times when people begin eating more healthy foods, they may also be taking some nutritional supplements or perhaps exercising more frequently.
Certain nutritional supplements, especially those that are used for body building, can make acne worse by changing the balance of hormones circulating in the body. Exercise can make acne worse, because the excess sweating leads to increased debris on the skin and clogging of pores.
I would suggest that you try a simple skin cleansing regimen, such as a daily antibacterial soap and some gentle exfoliation. If this doesn't work you may want to consider adding an over counter acne product that contains either benzoyl peroxide or salicylic acid, both of which help to unclog pores.
If these measure don't work, then you should set up a visit with your primary care doctor
or with your dermatologist
. They can take a look at your skin and suggest stronger prescription medications, if together you feel like these are necessary to help get the breakouts under better control.
