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.
Why get vaccinated? HPV vaccine is an inactivated (not live) vaccine which protects against four major types of HPV. These include two types that cause about 70% of cervical cancer and two types that cause about 90% of genital warts. HPV vaccine can prevent most genital warts and most cases of cervical cancer. Protection from HPV vaccine is expected to be long-lasting. But vaccinated women still need cervical cancer screening because the vaccine does not protect against all HPV types that cause cervical cancer.
