Suntan lotion may be ineffective or even dangerous
Conventional wisdom says "apply lots of suntan lotion and avoid the sun". I'm beginning to see reports that a number of suntan lotion brands don't work. I'm also seeing reports that suntan lotion may contain substances that are actually harmful to the body. Furthermore, new research is showing that people may not be getting enough sunshine.
For sure, too much sun can cause skin cancer. There is also evidence indicating a rise in tanning parlor use with an increase in skin cancers.
On the flip side, there is growing belief and awareness that people just aren't getting enough sun. If you aren't aware already, you definitely want to read about Vitamin D and cancer as well as Vitamin D and diabetes. This is probably one of the most important medical findings of recent years.
Here are some links I've compiled concerning sunscreen:-

Finally, related to this topic is a fascinating cream that supposedly heals non-melanoma skin cancers called Curaderm. No surgery needed!
