<s>[INST] i HAVE UGLY BLACK LEGS & ARMS. hOW DO i LIGHTEN UP? i AM FAIR SKINNED OTHERWISE [/INST] Hello! My dear, whatever may happen never refer to yourself as ugly. Beauty is a perception... and It's not always external.... ! Dark color of your arms and legs could be due to harmful effects of Sun. First and foremost always apply sunscreen. The right method of application is that apply liberally, 10 - 15 min before stepping out into the sun and re apply after 2-3 hours. A broad spectrum sunscreen such as Uncross aqua gel will be good and non-sticky for a tropical climate. For lightening, you can try creams such as Bolivia but considering it is a large body part it is usually not continent to apply creams. You can opt for Chemical peels such as Glycol or TCA peels, for which your cosmetologist can guide you. At home, you can try a mix of gram flour(began) with milk, apply like a paste keep for 5 min and wash it off, you can do this 2-3 times a week and follow it with a moisturizing lotion. Let me know the progress. Take Care Best Chat Doctor.  </s>
