Is it safe to put on sunscreen then put on the acne medication benzaclin (clindamycin and benzoyl peroxide)?
Sunscreen: Typically it is best to apply sunscreen after any and all topical medications. Applying medications over sunscreen can reduce the effectiveness of the sunscreen putting your skin at risk for sun damage. It is perfectly fine to apply medications and then sunscreen as this order will not disrupt the effectiveness of the topical medications. ...Read more
Yes: Sunscreens have a shelf life of three years. After this, they start to lose their stability and efficacy. You should see an expiration date on your bottle of sunscreen and should use it before that date. If you don't see an expiration date, write the month and year you purchased it on the bottle and toss after three years. Do not use any sunscreen that has become lumpy or has turned an odd color. ...Read more
Neutrogena, Alta MD: The neutrogena helioplex and the anthelios by la roche posay are my favorites. For acne prone skin, the alta md uv clear works well. It is important to use sunscreens with both uva and uvb coverage. Spf value refers to uvb protection. The new fda ruling requires uva protection labeling, which will be presented as + (lowest), ++, or +++ (highest). Reapply every 2 hours while in the sun. ...Read more
Sunscreen: Sunscreen combines organic and inorganic chemicals to filter the light from the sun so that less of it reaches the deeper layers of your skin. Like a screen door, some light penetrates, but not as much as if the door wasn't present. Sunblock, on the other hand, reflects or scatters the light away so that it doesn't reach the skin at all. ...Read more
Zinc oxide: Many of the sunscreens available in the us are banned in europe due to concerns about carcinogenic risk of some of the ingredients. However, the risk of skin cancer after a sunburn far exceeds any potential risk from sunscreens. The safest sunscreens are the barrier sunscreens containing zinc oxide or titanium. ...Read more
Skin Cancer: Sunscreens protect your skin from the harmful uv rays of the sun. In addition to damaging the quality of the skin, they can cause cancers to develop. I recommend the physical blocks (zinc and titanium) because they have a very good safety profile and work very effectively. If you are going to be in the sun - use a minimum of SPF 15 - follow product directions. ...Read more
Not really: The fda has recommended that the term sunblock be dropped as it is often very misleading and can result in patients believing they have more protection from the sun than they actually do. I agree, a good sunscreen with an spf of 50, that contains both a uvb protector and a metal such as zinc or titanium oxide for uva. That's all you need if you reapply it frequently. ...Read more
2 things: You need 2 things: a good uvb protector. This is what the spf rating refers to. Octinoxate is wonderful and safe. No more than a 50 spf. Anything higher is useless and to full of other chemicals. You must have a metal in it such as zinc or titanium. These protect against uva rays. Higher spf is nonsense. You must reapply them frequently and avoid the sun to be affective. Wear a hat and be well! ...Read more
Lots!: Put on sunscreen about 20 minutes before heading into the sun. Then reapply every 2 hours (more often if you get sweaty or wet). Make sure you use a broad spectrum sunscreen that protects against both uva and uvb rays. Also- remember your hat and sunglasses! ...Read more
Both are great: Sunblock normally consists of a physical blocker like zinc or titanium oxide which block and reflect both uva and uvb rays. Sunscreen usually means a chemical screen that interacts with the uvb rays to prevent sun damage. A combination of both us very common, but for very sensitive skin, a block is sometimes better. ...Read more
Sunscreen: Sunscreens work via 2 possible ways: 1) chemical blocks that breakdown the uv rays as they pass through the skin and 2) physical blocks that prevent the uv rays from getting to the skin. I recommend the physical blocks (zinc and titanium) because they have a very good safety profile and work very effectively. If you are going to be in the sun - use a minimum of SPF 15 - follow product directions. ...Read more

Shield vs filter: True sunblocks essentially create a shield to effectively block out the sun with zinc oxide being one of the most common preparations. They tend to be opaque. Sunscreens are chemical agents which filter out undersireable wavelengths of the sun and come in a variety of strengths and formulations. They tend to be clear. The diagram represents the spectrum of coverage. ...Read more
