Cheers Most people have that experience :-) But more seriously, one assumes that you are an individual with very little melanin and thus very little natural protection against UV skin damage. |

I use the house brands from CVS and Walgreens. Currently Walgreens "Sport 50" which I believe is SPF50. I don't see much difference versus the CVS SPF30 sun blocker I used before but I am not very sensitive to sun burns. I ride all year and the skin begins to tan more towards the summer which seems to make it less sensitive. Some tan remains through the winter because we have a lot of sunny days then as well. My rides are 3-5h. So far I haven't noticed any rub-off onto clothing but I only apply it to exposed skin. So it would only have a chance to rub into my cargo shorts from above the knee when pedaling. It just hasn't happened noticeably. -- Regards, Joerg http://www.analogconsultants.com/ |

Even after a 5h ride in the glistening sun his skin remains very white so the sun blocker must be protecting because it prevents even a minimal tan. -- Regards, Joerg http://www.analogconsultants.com/ |

But there are some doubting that sunscreen use significantly reduces skin cancer. As with other "safety" mechanisms, the lab tests say one thing but the long term population data says another. On the other hand I can assure you that the incidence of new basal cell cancers on my forearms is greatly reduced after using Sun Block and several friends have the same experience. Re your reference above, it appears to be a simple count of noses of those who used sun block daily and those who used it only infrequently but that would seem to ignore the fact that Basal Cell Carcinoma occurs in areas that is not exposed to the sun. The ratio seems to be about 1/3 on areas not exposed versus 2/3rds in areas exposed. Apparently the general scientific attitude toward Basal Cell, particularly, is: sal-cell carcinoma is a common skin cancer and occurs mainly in fair-skinned patients with a family history of this cancer. Sunlight is a factor in about two-thirds of these cancers; therefore, doctors recommend sunscreens with at least SPF 30. However, a Cochrane review examining the effect of solar protection (sunscreen only) in preventing the development of basal cell carcinoma or cutaneous squamous cell carcinoma found that there was insufficient evidence to demonstrate whether sunscreen was effective for the prevention of either of these keratinocyte-derived cancers. The review did ultimately state that the certainty of these results were low, so future evidence could very well alter this conclusion. One-third occur in non-sun-exposed areas; thus, the pathogenesis is more complex than UV exposure as the cause. If we are both reading the same report it appears that the report could not identify sun damage as the sole cause of cancer and said so. I can find nothing that states that UV damage DOES NOT, in some cases, cause cancer simply that the data is too uncertain to make a specific statement. |

The idea of tanning was, I suppose, because everyone else on the beach had a nice tan and I guess the "white skins" didn't want to stand out. It allowed the existing cells to tan by passing UVA, but blocked UVB. According to the London Telegraph's reporting, some modern sunscreen norms require that a UVA protection claiming label must be backed up by a UVA PF of at least one-third of the stated SPF (UVB) rating. Boris Johnson was wrong indeed: Letter-boxes (taped shut) are best! https://www.huffingtonpost.co.uk/entry/boris-johnson-defended-by-leading-imam-over-burka-comments_uk_5b6bf966e4b0530743c71456 But as rbt's readers exclusively die from the effects of wrong gear selection, lightweight component failure, bike route muggings, closed brewpubs, wildlife attacking, styrofoam lids or missing styrofoam lids, the only rbt-relevant sunscreen quality is whether it dissolves expensive grips and other plastic materials (including black lycra matters) and, maybe, if it can be used as an emergency chain lube. |
