There are several factors which are contributing to the occurrence of acne such as diet, less amount of physical activities and stress. Even certain type of medicines can lead to development of acne. Male hormone also called androgen is present in the milk which is responsible for the activation of the sebaceous glands and triggering them for the secretion of sebum. If the sebum is secreted in excess amount then it will block the pores of the skin resulting in acne formation. The androgen hormone present in the milk is known as testosterone which later gets converted into DHT due to series of reaction occurring in the sebaceous gland.  Milk as a whole contains several hormone but the amount increases even more when the cow is injected with the hormones for increasing the production of the milk. Drinking milk also increases the level of insulin in the body thereby causing acne. Researches carried out on the dairy industries has given proof to this theory but still there is no confirmed proof that drinking milk can result in acne formation. So the only best solution to know whether milk can give rise to acne is to stop the intake of milk and all dairy products for a week’s time and find the result.
