###Human: Please tell me about the best tan removal treatment available. ###Assistant: Hi. Tanning is due to sun. When you grow beard your hair protects the underneath skin hence it looks fair when you shave. Tan is not deep or stubborn. (attachment removed to protect patient identity). Keep Vitamin C application in evening and night and sunscreen should be used only when you go out in sun. It is useless to use sunscreen when at home. Any medication applied leave it for 2 to 3 hours before washing.
