One of the most damaging things to human skin is the sun. The sun emits ultraviolet rays that can cause further damage to skin that is already experiencing acne trouble, increasing redness and inflammation. Be sure to wear a sunscreen lotion with an SPF of at least 15 and has the ability to block UVA and UVB rays. Apply to the skin before entering the sun (at least 20 minutes in advance). Before applying, make sure the screen isn't acne sensitive.
If you have combination skin, you need to address two challenges at once. First you will want to get a handle on the oil production, usually in the "T-zone" extending across your forehead and then vertically down your nose and chin. The second, is to provide enough moisture to the dry areas of your skin, usually your cheeks. You can achieve both goals by assiduously washing with gentle cleansers that will remove excess oil, without stripping your skin completely and then making sure the dry areas of your face are adequately moisturized.
To prevent premature sun damage to your skin, it's very important to wear sunscreen. Choose one that blocks UVB and UVA rays. Pick an SPF factor high enough to continue to protect you after it begins to wear off. For example, an SPF of 10 will drop to a very low protection of SPF 5 after you sweat for a bit or wipe your face.
Be sure to use natural products on your skin. Don't use products that have a long list of ingredients that read like a chemistry book. These are bad for your body and your skin. Some specific chemicals to watch out for are triethanolamine (TEA), diethanolamine (DEA), and monoethanolamine (MEA). All three of these chemicals can be found in many US skin care products, but you should know that they are not allowed in European countries because they have been found to cause cancer!
