I'll cut to the chase....
I do not have any professional qualifications regarding dermatology or the like.
I do have mild/moderate acne vulgaris, that comes and goes when it pleases, since the age of 13ish and I am 28 years old.
I am trying a diet of plenty fresh veg and fruit, (predominantly veg) brown rice, lentils, chickpeas, flax seeds, nuts.
Drinking one glass of water and Apple Cider Vinegar (1 table spoon) a day.
Drinking plenty of water.
Reducing dairy intake.
Reducing potato intake.
Reducing sugar intake.
Reducing highly processed food.
Also concentrated tomato pasta sauces and tomato paste (it may exacerbate my acne, it feels like it does)
Also it is possible highly spiced food may aggravate it also.
Factors I cannot control is weather change.
I am also putting ACV on my face, 1 part water, 1 part ACV, but instead of leaving it on, I wash it off after 30-60 seconds
I have been doing most of these things for about 4 days, I will let you know in a few days or so how things are going, thanks for reading and all the best with your endeavors.
