<s>[INST] Hello doctor, I am 23 years old and I have this problem for the last three years. My underarm is too dark and I cannot wear sleeveless tops. I am getting married soon and am really embarrassed because the sensitive area is also with dark skin and I really need an absolute solution. [/INST] Hello. I have noted your concern. Regards. For further queries consult a dermatologist online --> </s>
