Visit the dermatologist or esthetician. While you may have a general idea of what kind of skin you have, the best thing to do is make an appointment with a skin professional like a dermatologist, esthetician or even your facialist. Since they see skin for a living they will be able to give you a proper and specific diagnosis down to areas of your face. Your forehead may be dry, but your chin region might be slightly oily. They will give you a plan on the best way to clean your skin.

Go to high-end department stores. Macy's, Bloomingdale's and Nordstroms all have high end beauty counters. If you are someone who has the means to spend a little extra money on the finest soaps and creams, then by all means go ahead. Communicate what you learned from your dermatologist or esthetician with the sales associates. However, if you do not want to spend lavishly on their soaps and lotions, ask for free samples! It's their job to give them to you. Then at home, do a trial and error process, find what works for you and makes your face feel fresh and clean. Then go to eBay and buy it at a discount!

These brands are frequently on sale and also frequently provide coupons in your local Sunday paper. Other stores like Costco and Big Lots offer these products at steep discount when you buy in bulk.
