Pigmented lesions are extremely common – and no wonder, for natural ageing processes and hormonal changes often affect the distribution of the pigment melanin in the skin. This is how irregularly pigmented skin, melasma (dark, blotchy discoloration of the skin on the face) as well as freckles and age spots develop. But all these conditions can be treated gently and effectively using the latest light and laser therapy applied at Swiss Derma Clinic.
