Once I passed through puberty, I hoped that I'd never have to deal with acne again. Guess again. Acne can affect you at any time in your life, so taking care of your skin is of lifelong importance. Some skin types are oilier than others and therefore are more prone to skin blemishes. If you have to deal with acne—whether mild or severe—there are products out there that can help you deal with your reactive skin. You don't just have to sit back and accept temperamental skin.
The best way to combat acne is to simply take care of your skin in a consistent and diligent way. You have plenty of options available for specific acne products, but none of them will work unless you have a thorough skin care regimen that you diligently follow. If your acne is more mild or only crops up with hormone swings, then you can find skin care products that fit your skin type and use acne-specific products when you have a breakout. If your skin always seems to be in breakout mode, then you'll want to use skin care products that are for acne.
The best products to use for bad acne are oil free. When you have bad acne, you have too much dirt and oil on and in your skin, so definitely don't use products that add to the problem. If your acne is moderate, then keeping a lookout for oil-free products should be adequate, but if your acne is, well, more than moderate, then you have several very acne-targeted products at your disposal. For instance, Proactiv is an acne skin care line that hits acne hard. You don't need a prescription for Proactiv, but you do have to order it, and it will cost more than what you'll find in the local drugstore aisle. If you're especially concerned about your acne, you can go see a dermatologist, who can prescribe hard-hitting medication.
Sometime else to remember about acne skin care products is that the key ingredient in these products is benzoyl peroxide, a drying agent. This chemical works to dry your skin, and when you're in the middle of a breakout (even if that breakout is all the time), then your skin has too much oil and needs to be "dried out," in a manner of speaking. Some people have allergies to this chemical, so if you start having adverse reactions from the acne products you use, go see a dermatologist, and he or she should be able to get you on a product that you'll respond to positively.
