If you eat right and get a little sunshine every day, you shouldn't need to take a multi. Try to eat as many fruits, vegetables, and greens as possible - and get 10-15 minutes of full sun exposure (best source of vitamin D) everyday. A great way to get your fruits and greens is a "green smoothie". Basically you take equal parts fruit (apples, bananas, mangoes, berries, etc.) and greens (spinach, kale, chard, collard greens, etc.), add a little water and/or ice, blend well, and voilà...you've got a great tasting smoothie packed with pretty much every vitamin and mineral known to man. You also get tons of healthy plant fiber, amino acids, phyto-chemicals, and more.
A dermatologist diagnoses perioral dermatitis by examination. No other tests are usually done. The first step in treating perioral dermatitis is to discontinue all topical steroid creams , even non-prescription hydrocortisone. Once the steroid cream is discontinued, the rash appears and feels worse for days to weeks before it starts to improve. Heavy face creams should also be stopped. One must resist the temptation to apply any of these creams to the face when this happens. Think of the face as a cream junkie that needs a "fix"- one needs to go "cold-turkey".
The general goals of treatment for dermatitis involve reducing symptoms, healing the skin, and preventing exposure to irritants and allergens that cause outbreaks. Special creams and lotions that contain anti-inflammatory compounds may be used to soften and soothe the skin, and topical corticosteroids may be applied to the skin to relieve itching. However, corticosteroid-containing medications can cause skin-thinning, dilation of superficial blood vessels that leads to unsightly red spots on the skin, and abnormal skin pigmentation. There is also a risk of systemic absorption of corticosteroids, which can lead to disruption of normal physiological steroid production. Topical immunomodulators (TIMs), which are steroid-free skin medications, have been developed. These agents work by inhibiting the activation of immune substances. However, due to their potentially dangerous side effects (., lymphoma), TIMs are considered second-line treatments for dermatitis. Other therapies used for dermatitis include antihistamines, phototherapy, which uses ultraviolet radiation to suppress immune reactions, and photochemotherapy, which combines phototherapy with the administration of a light-sensitizing compound such as psoralen.
