Hydroquinone For Pigmentation
Our skin is able to
protect us from the harmful sunlight with a substance called
melanin. As more melanin is produced, the skin gets darker and
the more protection we get against the sun. Melanin is
produced by pigment producing cells called
melanocytes. The amount produced is determined by heredity and
exposure to the sun. Asians tend to produce more melanin when
exposed to the sun, hence they tan quickly and are as at risk
for severe burns as most Caucasians are.
However, melanin can be over-produced due to
factors such as sun exposure, hormonal changes (pregnancy,
menopause), ageing or certain medications. Excessive melanin
causes pigmentation problems that show up as abnormal dark
blotches on the skin, causing unevenness in the overall
appearance of the skin.
Pigmentation can be lightened and controlled
through the use of hydroquinone, which works by stopping the
production of melanin without destroying them.
It is advised that
any persons using a hydroquinone cream on their skin to avoid
exposure to the sun, which can stimulate the production of more
melanin and pigmentation on the skin. Hydroquinone should also
only be used in low
concentrations (2% or 4%), and only
as directed by your doctor.
