Hello and welcome to healthcaremagic
Hyperpigmentation of face, commonly known as melasma, is managed on 3 basic principle steps:
-Inhibition of melanogenesis to prevent synthesis of new pigment and thus relapse.
-Exfoliation to shed away the existing pigment and
-Sun protection to prevent further sun induced darkening
If I was the treating doctor I would suggest you to use a broad spectrum sunscreen throughout the day, that which offers both UV A as well as UV B protection. Reapply the sunscreen every 2-3 hours, in adequate quantity.
At night you could use a cream containing one or more of the skin lightening agents like
kojic acid,
hydroquinone, azaleic acid etc. These ingredients inhibit synthesis of new pigment by inhibiting melanogenesis.
Simultaneously you could also opt to undergo a few
glycolic acid peeling sessions from a
dermatologist, to exfoliate existing pigment.
Metasone plus cream is a triple drug combination of a topical steroid+hydroquinone+
tretinoin. It is a gold standard combination for treatment of hyperpigmentation. Though it is very effective for facial hyperpigmentation, however, it should never be used without a dermatologist 's supervision because it may cause side effects like irritation, acne,
photosensitivity etc.
This combination is often misused by patients for extended periods of time and ultimately the patient lands up with side effects like acne, photosensitivity, telangiectases etc.
In any case this combination should never be used for more than 2-3 months at a stretch because of fear of these side effects.
Therefore I would suggest that you visit a dermatologist for proper advice regarding hyperpigmentation and follow up while you are using this cream.
