Aloe, goldenseal, vitamin C, and probiotics are all good and recommended for topical or a temporary treatment for skin inflammation and acne, but there is no substitute for getting at the root source.

Managing stressors...see above treatments, also meditation and exercise...

and most importantly of all...stopping accumulation of toxins and irritants at the source.
Avoid these most blatant and common systemic and skin irritants wherever possible:
-Smoking/drugs/alcohol
-Dairy, and most particularly cow's dairy (known to be poorly digested)
-Gluten (creates leaky gut and inflammation...often expressed in the skin)
-Excessive richness (sugar, candy, milk chocolate, fried foods)

All of these things are known to create loads of systemic toxins which also aggravate the skin. As a vegan you are presumably avoiding dairy, but you may still have loads of gluten in your diet.

Also...if there are other allergens or chemicals in your diet (soya, corn, nuts or legumes, certain fruits, etc) or personal hygiene products (shampoo, oils, lotion, etc) that trouble you personally, you should avoid them wherever possible. Anything consumed or applied or to which you are exposed will affect the skin.

Drinking water & good herbal teas which tonify and purify kidneys, liver, skin, &/or digestive system will tend to help the skin.

Peace & blessings,
