Start small. It's a safe bet you really don't have to buy over a dozen different lines of skin products to have healthy and nice looking skin. Start with a simple cleanser, then you want something that is good at both cleaning your skin and preventing breakouts but won't slather a bunch of oil into your pores or leave your face feeling stripped. It usually is not a problem to use a simple cleanser that is non-prescription. Be sure you buy a product for adults. Products marketed to teens are usually harsher and might contain products that could harm an adult face.
It's important to allow your products time to be effective. You'll look in vain for that miracle product that gives results in a day, or less. To be fair, use a product for several weeks or more before you decide it doesn't work. You'll know by then if the cleansing is adequate and break-outs are improving. At that point you can move to the next product and repeat. A lot of people use multiple products before they find one they like and that works.
Do you have especially sensitive skin? You may want to try an all-natural cleanser if you experience break-outs because the chemical ingredients may be causing this. You can find cleansers with avocado or egg whites, so that could be a good alternative for you. Perhaps some olive oil is all you need (believe it or not, olive oil is fantastic for your skin). Sometimes skin types are too sensitive for the products in stores. If that's you, then go check out your kitchen cabinets and the refrigerator because you may be able to whip-up something that will be perfect for you and your skin.
You have various methods for identifying the best skin care product for your skin. If you don't mind the trial and error approach then you can just purchase products until a good match crosses your path. Taking this approach will lead to a few missteps but that is common. Stick to these methods and you will find what works and what does not.
