Melanin is the skin’s natural defence shield against the potentially carcinogenic effects of UV rays in sunlight. The skin, which is naturally endowed with melanin, produces more of this pigment in response to sunlight. However, there comes a point when it all goes out of control as a result of overexposure or age-related changes in skin – or both factors working in tandem. Hyperpigmentation may also manifest as melasma. Acne can leave behind deeply pigmented spots.Whatever the origin of hyperpigmentation, there are a slew of techniques and technologies to deal with it. Your dermatologist may often select TCA Peel (trichloracetic acid), a non-toxic peel which is a chemical cousin of vinegar. TCA has been in use for over two decades now and has proved to be an efficacious solution. In certain cases, especially melasma, many lasers are difficult to use but deep-acting TCA has the ability to get right down to the problem.
