Sun Damaged skin is the main cause of pigmentation issues and is predominantly seen in light skinned individuals . For those with dark skin pigmentation tends to be related to melasma or post-inflammatory hyperpigmentation caused by hormonal issues , acne , psoriasis , burns or injury . When the skin is exposed to UV radiation , hormonal imbalance or trauma , it activates melanocytes which increase melanin production . Melanin is the pigment that gives the skin color. When melanin is not evenly distributed it can cause freckles , brown spots or patchy pigmentation . Treatments available at Dr Kora Aesthetics for Sundamaged skin
