Remember that the consumption of oily or fatty foods does not cause acne, nor will it make it worse. No studies – scientific or otherwise – have ever linked the two. Many bodybuilders also believe that tanning beds keep acne under control by “drying” the skin, but this is not the case. A tanning bed actually saps moisture from your skin and leaves the oils behind, and over time, tanning can cause skin cancer. Finally, using antibacterial soap to wash your skin can cause certain strains of bacteria to become resistant to the anti-bacterial agent, which can have a significant impact on your health.
Oral corticosteroids ( Prednisone , Solu-Medrol ): Acne may be caused by systemic steroid use, but "steroid acne" is usually characterized by an acute eruption of tiny papules and pustules over the chest and back. Oral steroids may play a role in the treatment of cystic acne, not on their own, but as an adjunct to other antibiotic or isotretinoin therapy to try to suppress scarring inflammation in the skin as fast as possible. This may be especially important with the initiation of isotretinoin therapy, and many providers will start low-dose systemic steroids at the start of isotretinoin therapy in order to block the anticipated flare in disease that retinoids may trigger.
In addition to the mentioned side effects several others have been reported. In both males and females acne are frequently reported, as well as hypertrophy of sebaceous glands, increased tallow excretion, hair loss, and alopecia. There is some evidence that anabolic steroid abuse may affect the immune system, leading to a decreased effectiveness of the defense system. Steroid use decreases the glucose tolerance, while there is an increase in insulin resistance. These changes mimic Type II diabetes. These changes seem to be reversible after abstention from the drugs.
