1 Vitamin E - It doesn't directly reduce melanin production but it is effective in reducing hyper pigmentation caused by melanin over production.  Use a good SPF protection to all the exposed parts before going out in the sun and keep ypurself covered (It may get hot though...so upto you!!)
The HPV vaccine protects preteens, teens, and young adults from Human Papillomavirus (HPV). Research shows that when boys and girls are vaccinated early - at 11 or 12 - they're better protected from the serious health problems HPV can cause, including certain cancers and genital warts.
Three vaccines are available to prevent infection by some HPV types: Gardasil, Cervarix, and Gardasil 9. Both protect against initial infection with HPV types 16 and 18, which cause most of the HPV-associated cancer cases. Gardasil also protects against HPV types 6 and 11, which cause 90% of genital warts.
