This sounds probably like some irritant or may be an allergic rash
. Alcohol and spicy food may induce flushing
but its more of generalised redness involving forehead, cheeks and chin.
To treat the area, apply any mild steroid cream like hydrocortisone
. Acoid sun and to bro n safe side avoid alcohol or spicy food. It should resolve in few days. If it does not, meet a dermatologist
Hope this helped.
