SPF refers to

Passage 1:PIGMENTATION- UNMASK THE MASK
Melasma is a skin condition that manifests as brown patches on the forehead, cheeks, nose and upper lip. It occurs primarily in women being commonly associated with pregnancy, oral contraception, hormone replacement therapy and sun exposure. Over 30% of patients have a family history.

Broad spectrum sunscreens with an SPF over 30 protecting against both UVA and UVB rays are essential. Chemical peels, microdermabrasion and laser surgery may help but many equally harm by causing irritation and aggravation. Besides pigmentation can recur upon sun exposure and /or hormonal imbalance.

Two points to remember are that treatment is a slow process usually taking several months or more and that results depend upon the depth of pigmentation. Epidermal Melasma (where pigment is located superficially in the upper skin layer) is much more successfully treated than dermal Melasma (where pigment is deeply embedded) and whose treatment basically helps to control any spread.

According to the Wood’s Lamp Surgery that the pigmentation on the cheeks are epidermal while that on the forearms are dermal. In this case facial pigmentation could be successfully treated whereas the forearm pigmentation could be prevented from spreading. But could not be completely cured. Technology like Wood’s  Lamp is invaluable in accurately diagnosing such cases. After a few doses of Sepia you will be delighted to find your hyper pigmentation fading and you can face the future with confidence.
