Apart from color change of the skin, melasma is harmless and does not cause any other symptoms like irritation or itching of skin.
Melanin is the pigment responsible for skin color. Based on the content of melanin melasma is categorized into 4 types. Epidermal melasma is one which there is excess of melanin pigment in the epidermis layer (superficial) of the skin. Dermal melasma is characterized by special cells called melanophages which is seen throughout the dermis layer of the skin. Mixed type is one in which symptoms of both epidermal and dermal melasma are seen. Fourth type (unnamed) is seen developing on dark complexioned people largely.
Tests and Diagnoses :
Melasma can be identified easily by physical examination of affected skin. It leaves dark brown colored patches on your face. Visual examination is enough for confirming melasma. Very often mixed type of melasma is seen affecting the epidermis and dermal layer of the skin causing discoloration on the face.
Very effective treatment for melasma patches is to apply creams that contain 2% of hydroquinone. It is available over the counter in the brand names of Porcelana and Esoterica. Your doctor may give prescription creams like Glyquin, Obagi clear or Tri Luma. Generally if you want to get hydroquinone concentration more than 2% you may require a valid prescription. You need to apply the cream on the dark brown patches twice or thrice a day. In case you are planning to go out in the hot sun, you should apply sunscreen lotion that contains SPF (sunscreen protection factor) of more than 30%.
Treatments are the same for all types of melasma but the above creams will respond well for the epidermal type of melasma. For many women, no creams are required for managing melasma since it will disappear after some months. Women who develop melasma patches during pregnancy stage will find these patches completely disappearing after delivering the child. Similarly women using birth control pills will find all the melasma patches resolving without any treatment after they discontinue the pills.
For severe cases of melasma your doctor will prescribe creams that contain high concentration of hydroquinone or combination of HQ with tretinoin or corticosteroids. Drugs like retinoic acid, tazarotene, glycolic acid or lactic acid mixed with HQ. All these medications can cause adverse effect like skin irritation temporarily. Ochronosis is a condition that causes permanent skin discoloration for women using HQ for prolonged period. Chemical peeling, micro dermabrasion and laser treatment are some other methods used for treating melasma.
In chemical peeling method the strength of the chemical to be used will be decided by your doctor based on the intensity of dark patches of melasma. He would administer various combinations of chemicals mixed with HQ for effective resolution. In micro dermabrasion method, vacuum suction is done along with exfoliation of top layers like aluminum oxide or diamond chips. Your doctor will adjust the vacuum pressure based on the intensity of patches and your capacity of tolerance.
In any type of treatment method, you cannot expect dramatic results and you need to undergo several sessions for getting positive results. Further you have to continue using sunscreen creams along with this method. You have to discuss with your doctor about the possible outcomes before spending for the procedure.

Some doctors use azelaic acid for treating melasma which is a product that does not contain HQ. Azelaic acid 15-20% is effective in treating melasma without any major side effects. Similarly Tretinoin, Renova are some other non-hydroquinone products for getting good results. You need to use sunscreen formula that contains SPF factor of 30 or above along with hydroquinone for getting effective results.
