Absolute best protection against skin cancer
The best protection against skin cancer is to protect yourself against sunburns. Sun exposure, even without burning, could possibly contribute to that, but the worst is to use sun exposures and have so much damage that the skin can’t handle it, which usually results in redness and irritations of sunburn. In order to do that, you really need to use more than just the sunscreen.
You need to time your outdoor activities if you are fair skinned, so that you are outside before 10 or 11 in the morning or after 4 in the afternoon. It is also important to be under shade such as an umbrella or overhang of a building and also to use sun protective clothing because that protects better than sunscreens.
Sunscreens should be used in addition to protecting against the reflected light from water, sidewalks or sand. This is the start of best natural skincare.
