Pull out a magnified mirror, turn on a bright light and take a long look at your reflection. Do you have dry skin or an oily complexion? Knowing your skin type will help you decide which skin care regimen is right for you. If you suffer from regular breakouts or acne, you may need to seek the help of a professional to ensure your skin is in great shape by the wedding. Some medications take up to 12 weeks to take effect, so book an appointment with a dermatologist for a consultation at least six months in advance of the big day. Even if you don't have a year to prep your pores, it's important to adopt a healthy skin care regimen as soon as possible.
