Re: Bleach Creams ! ( abroad)
HQ in high dosages (10%) found in creams used in Africa and India-Pak is dangerous. The ones prescribed in the US --4%-- is safe to use but with precautions. You must wear sunscreen always, dont use if for more than 3 months, (sometimes they say 1 month) to be on the safe side. The reason being HQ can sometimes make the area under treatment darker in some people due to prolonged use...hence the resting period. Prolonged use of high % HQ thickens collagen fibers which damages the connective tissue resulting in blotchy skin.
*2% (non prescription) is ok to use but again must use sunscreen at all times when outside.
(HQ alters production of Melanin)
