This is thought to play a role in the development of perioral dermatitis.
Case studies show that the use of moisturizers plus cosmetic foundation on a daily basis contributes to an increased risk of developing perioral dermatitis.
Persons with oily skin who do not properly cleanse with water and soap (or other cleanser) are also susceptible.
Daily use of heavy sunscreens also tend to trigger this type of rash.
The etiology and pathogenesis is unknown according to western biomedicine.
The rash of perioral dermatitis is rather distinct though it can often be misdiagnosed as eczema (atopic dermatitis), acne, allergic contact dermatitis, or even rosacea.
Oral (internal) antibiotics are the treatment of choice in western dermatology.
Internal herbs are the treatment of choice in Traditional Chinese Dermatology.
Sometimes the rash only appears at the eyelids (despite the name “perioral” dermatitis).
Tiny papules (small bumps) and small vesicles (bumps filled with a small amount of clear fluid) will appear on an erythematous (red) base. The skin may feel tight and dry with occasional mild itching or burning.
Most of the time the rash will be symmetrical – appearing on both sides of the face.
I am so curious to discover the correlation here (if one exists).
In most cases, perioral dermatitis responds quite well to treatment, though there are times where is recurs or becomes stubborn (like in the health care workers mentioned above).
