Perioral dermatitis is a common skin condition which typically affects the skin surrounding the mouth (perioral) and the nose (perinasal).  Occasionally, the rash will surround the eyes (periocular) The condition consists of groupings of small, red bumps which may be accompanied by itching or tenderness. Skin in the affected area may be flaky, dry and pink in color. The area tends to be sensitive and may sting or burn with minimal irritation.  Lesions usually occur around the mouth, and often involve the skin around the nose as well. Lesions may also spread to the skin of the chin, cheeks and eyes. 

The exact cause of perioral dermatitis is unknown. There are several factors which may be related to its development, most likely a hormonal change leading to a regional overgrowth of the skin's colonizing microorganisms.  This condition is similar to acne in that it seems to be triggered by hormones and possibly the acne bacteria known as P. Acnes.  It also has small papules(bumps) and pustules(pimples) but is on a background of red flaky skin.  Other contributing factors may include use of certain irritants (like exfoliating lotions or scrubs), some cosmetics (often anti-aging creams), or topical corticosteroids (including nasal spray steroids).  The condition very rarely affects men, but it often develops in prepubertal boys and girls.
