Effectiveness of Sunscreens
There was a discussion here awhile ago about the effectiveness of sunscreens. It was said that most sunscreens in the U.S. are ineffective because they're photo-sensitive and break down easily in the sun. Neutrogena Dry Touch is one of SPFs that was recommended in that thread. But, then I read that lotions with certain ingredients - avobenzone was one - are what you need. As long as it has those ingredients and is broad-spectrum. I have Coppertone Water Babies SPF 50 with Avobenzone that I wear year-round. How do I know if it is a "durable" sunscreen? I'm assuming it's not because it wasn't listed with the Dry Touch, but I guess I'm confused because the article I read says it's a good one. There doesn't seem to be much clear information out there on this topic. I'm also not sure what is really true and what is being put out there to sell products. Can someone please explain it to me? Is my sunscreen ok, or do I need a stronger one? I wear sunscreen year-round to prevent pre-mature aging, but in the midwest where it's cloudy and 30 degrees this time of year, is it really necessary? Plus, I'm kind of in the mindset that we're all going to age, anyway. I don't want to be wrinkly at 25, but I'm close to that age and don't have a whole lot of aging signs. How much of it is stress and genetics related compared to sun? When you're 30, you're going to show signs of aging regardless of what SPF you use? I'm just trying to decide if buying a certain type of SPF is worth it. I'm definitely wearing it because I'm fair-complected, but I really don't know what to buy at this point.
