For reasons that almost no one can explain, beauty and light (whiter) skin have been long associated. But our bodies are usually a mix of many pigments and an entire industry of products exists to help people correct skin tone issues.
One obvious place where skincare creams are regularly used is the face. Dark spot correctors, sometimes in cream form or a serum, can be applied for spot treatment.
These are sometimes effective (and sometimes not) in treating age spots, liver spots, acne scars and other blemishes. Price and performance range widely.
The face is not the only area where skin Whitening is a priority. There are now treatments for underarm lightening, anal bleaching and various creams to whiten genitalia also.
