hi im dr satya
welcome to health care magic.
glowing face with lomella is due to hydroxyquninone . a component which alters the melanin
content of the melanocyte
thus bringing about glow on your face, please do understand that at any time if there is an over exposure to sunlight there will be a change of color.
regarding the duration it is necessary to know whether the cream was prescribed by the doctor or purchased from a medical shop.
kindly consider use of a sunscreen.
avoid use if there is any redness
of the skin.
thank you take care
