To reduce the appearance of spots and flakes, exfoliation is required before applying powder. Exfoliation can be mechanical nature or chemical peel with appropriate products. For mechanical exfoliation, I advise you to find a suitable sponge or a device that will not be too hard on the skin.

After cleansing moisturize the skin with essential oils, serums and creams, but if you don't know in what order to apply products, I recently wrote a post on that topic so check it out. 

Brushes and Beautyblender will help you in the perfect foundation application, and my suggestion is to invest in Beautyblender sponge that will apply foundation without disturbing the upper layer of skin, which is why you will have fewer problems with flakes.
