The incidence of sensitive skin, irritation, and dermatitis is increasing and reported to be common among 30-50% of women-depending on the race.  It seems that Asian and Northern Europeans have the greatest occurrence. 

There are two types of sensitive skin.  The first is induced by increased nerve activity which produces burning or itching.  This type of sensitivity is due to abnormal skin function, nerve enlargement or hyperactivity and is not visible on the skin surface.  Applying even mild irritants will activate the sensitivity.  Also, continued low fat diets and lipid lowering medications can make the skin more susceptible to a reaction. 

The second type of sensitive skin is visible with redness, hives, scaling, burning, and itching when exposed to sunlight, water, humidity changes, and topical agents.  This sensitivity is usually due to exposure to topical irritants, allergic reactions, hayfever, asthma, and a history of dermatitis.  It is reported that approximately 30% will react to retinoids, 15% will be come allergic to tea tree oil, and 10% will have a reaction to UV light. 

How do you treat sensitive skin?  It is better to use fragrance free products as opposed to unscented of hypoallergenic products.  Stay away from products containing essential oils, formaldehyde, quaternium 15, and SD alcohol.  You should also avoid steam, paraffin treatments, saunas, scrubbing products, microdermabrasion, and acid or enzyme exfoliants. 

Ceramides are necessary for improvement.  Sunscreens are imperative but only use ones containing zinc oxide.
