Use a natural moisturiser like aloe vera, egg oil, coconut oil, cocoa butter, kokum butter etc. Good skin care is a must and will reduce discomfort later on. Make sure to choose a product that is perfume-free; the last thing you want is to scorch your most intimate areas with harsh chemicals. Something containing vitamin E and/or aloe will go a long way to making you more comfortable and may improve healing time and appearance. Note that shaving and depilation leave your skin vulnerable to infection. Though applying rubbing alcohol will help prevent these infections, it will also burn, especially for women. Use at your own discretion. Getting started is the hardest part — after you wrangle your hair into the style you want, though, upkeep is fairly easy.  Re-do shaved areas every two or three days. Re-trim hairy areas every one or two weeks. Re-wax every four to six weeks.

How would you rephrase that briefly using Vietnamese?
