Brief Answer:
Possibly excess androgens or toxins being expelled from the body

Detailed Answer:
Hello sir and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. Oily skin also known as seborrhoea is due to excess oil from the skin; it is more commonly possible in men (Especially those who are in and around their puberty, and the elderly men). It does have a little to do with alcohol consumption, but if you stopped just recently I would have to say that this is a good thing, because your body might just be trying to expel as much of the toxicity from your body as possible.

I hope you find my response helpful. Please feel free to write back to me for any further clarifications, I am always here to help.

Best wishes.
