What is Perioral Dermatitis?

Perioral Dermatitis is a skin condition that is often mistaken for Rosacea. According to the National Rosacea Society, Perioral Dermatitis causes a red and bumpy rash to form on the lower portion of the face, particularly around the mouth. The appearance of Perioral Dermatitis can look very similar to the pimples and spots of Subtype 2 Rosacea which explains why it is often mistaken for the condition.

The cause of Perioral Dermatitis is said to be close to an allergic reaction rather than being classed as a chronic inflammatory condition. Many medical professionals state that the condition could be caused by the use of hash cosmetics, fluorinated toothpaste, steroid creams, steroid sprays, sunscreen and other products.

The condition differs from Rosacea because with Rosacea the cause is unknown but with Perioral Dermatitis the cause is said to be clearer with triggers being easier to spot. That being said Perioral Dermatitis still isn’t completely understood and some professionals think there may be a link between the condition and Epidermal barrier dysfunction, activation of the innate immune system, altered cutaneous microflora and follicular fusiform bacteria. Perioral Dermatitis can affect anyone but according to DermNet New Zealand the condition often appears in women between the ages of 15 and 45 years and is less common in men.
