Luminescent Serum The first step in fixing your skin problems is figuring out what type of skin you have. Without knowing what type of skin you have, it is nearly impossible to choose the correct product to fix any issues you may be having. Understand your skin type before you start treating it.Even if your skin is oily, you still need to moisturize. Make sure you apply a moisturizer after you wash your face and before you put makeup on. Even though it may seem unneeded, it will help balance the production of oil. If you are overzealous in drying your oily skin, you will find that it will respond in kind by producing more oil.
