From the mid-1980s, Jackson's appearance began to change dramatically. The changes to his face, particularly his nose, triggered widespread speculation of extensive cosmetic surgery, and his skin tone became much lighter. He was diagnosed with the skin disorder vitiligo in 1983, which results in white patches on the skin and sensitivity to sunlight. To treat the condition, he used fair-coloured makeup and likely skin-bleaching prescription creams to cover up the uneven blotches of colour caused by the illness. The creams would have further lightened his skin. The lighter skin resulted in criticism that he was trying to appear white. Jackson said he had not purposely bleached his skin and that he was not trying to be anything he was not.
