Melanin is a natural pigment that determines skin, hair, and eye colour. Hyperpigmentation has multiple causes and may be focal or diffuse. Most cases are due to an increase in melanin production and deposition. Hyperpigmentation can occur as a result of hormonal and age-related changes, sun damage and post inflammatory response (i.e. mark left by acne). At Clapham Skin Clinic we offer several treatment options for clients affected by hyperpigmentation; these include Obagi product range (such as Obagi Nu-Derm System, Obagi Vitamin C serum, Obagi blue peel radiance and blue peel. facial peels such as Obagi Blue Peel Radiance and Obagi Blue Peel), Cosmelan and Neo-Strata range. Choice of treatment is determined by the severity of the hyperpigmentation and the skin type.
