Most of the dermatologists say that the mixing up of dry cells with sebum secreted by the sebaceous glands causes adult acne. The reason may be partially right but not absolutely. Actually, the cause of acne in adult is the toxins and wastes inside the body that cannot be properly eliminated.  The body expels toxins through the liver, kidney, colon, small intestine, and other organs. If any of these organs is weak and cannot do its function properly, the body tries to flush out unwanted toxins through the pores of the skin.
Mostly adult acne can be seen in women a few days before the menstrual cycle. During this period, the decrease of estrogen and increase of progesterone urges the sebaceous glands to produce more oil. Women who are pregnant often experience bouts of acne due to hormonal fluctuations. It can also be experienced during postmenopausal phases due to the decrease in estrogen level.

One of the alternative therapies for acne is vitamin therapy. Nutritionists generally suggest 30-50 mg zinc supplements to reduce the inflammation and to heal the damaged skin. Chromium helps to breakdown glucose in the body. Vitamin A reduces the sebum and keratin production, but high doses should not be used.

Homeopathy treatment by an experienced practitioner is considered as a good alternative method to acne help. Food and nutrition experts suggest food high in betacarotine such as carrots, pumpkins, yellow and orange fruits and vegetables.
For acne help you need to change your lifestyle. If you really want to get rid of acne change yourself in as many ways as you can. Have a healthy balanced diet. Avoid sugar, caffeine, alcohol, processed food, etc. Exercise should be taken to boost the blood flow.

Sleep for at least 6-8 hours daily. Try to overcome stress. Sebaceous glands become more active when we are in stress. Drink a lot of water to calm the body system.
