at the corners of my mouth. every morning i have been able to "pop" at least one of them and a white pus will come out. I do get the occasional cold sore (3-4 per year), but i dont get them at the corners of my mouth. Additionally, the corner of my mouth seems a bit reddish and irritated. You cant notice the white spots
Perioral dermatitis, a condition related to acne vulgaris, consists of red papules that may appear microvesicular that typically affect the nasolabial folds, perioral area or perioccular area. It usually affects women between the ages of 20 and 45.

It is commonly caused by the use of fluorinated topical glucocorticoid steroids to this area.
It is treated in a similar manner to acne vulgaris with tetracycline antibiotics or erythromycin but, without the use of topical steroids.
Recently, photodynamic therapy (PDT) has been reported to be helpful, although large studies have not yet been performed.
Roaccutane has been used in patients with severe perioral dermatitis with some benefit. Do consult with a dermatologist regularly.
