###Human: How can I treat the skin patches on hand and forehead? ###Assistant: Hi. I have gone through your case. In my opinion, you are having different types of lesions on your face and arms. For the face lesion, apply Clindamycin gel two times a day only on the raised red lesion. Lesion around the eye may take somewhat longer time to heal. Brown lesion on arms is due to sun and dryness. Please regularly apply sunblock lotion with SPF 40 or above to prevent further more lesions. These are called lentigines. For dryness use E45 lotion. No cause for the facial lesion. Sun exposure for brown arms lesion.
