We here at Sundicators have been waving the flag for sunscreen and sunscreen re-application from the very first post this blog has presented. We’ve also touted our amazing Sundicators UV monitoring wristbands that alert its wearers, by way of simple color-changing technology, when to re-apply. But let’s for the moment assume that you don’t have any Sundicators and you’re asking yourself the question, how long does sunblock last on your skin?
The amount of time that sunscreen lasts on any given individual is not really fixed. There are actually several factors that contribute to the weakening of its effectiveness on people. Swimming, jogging, or any other activity that causes a person to sweat will reduce the amount of time that sunblock will maintain its protective abilities. And if you are in fact a swimmer, you should certainly re-apply sunscreen just as soon as you emerge from the pool, lake or ocean.
Better To Be Safe Than Sorry Later
Generally speaking though, if you have no way of monitoring the reduction of your sunblock’s efficiency, the rule is to re-apply it every two hours that you spend outdoors. But again, if you’re active in any kind of athletics, or are involved in any significant movement, it’s better to do it even more often than that. Because significant amounts of movement will hasten the erosion of the sunscreen’s effectiveness on your skin. We’d go into more detail as to why, but we trust you to understand why that should be kind of self-evident.
One of the hardships that all sun-safety proponents face, is to try and drill into people that their initial application of sunscreen is simply not enough. Unfortunately, many of those who remember to apply it before they go out for the day believe that that one coating is sufficient. The truth though is that it isn’t. In fact, people who apply a single use of sunblock and then spend several hours, or even all day, outside, may like as not hadn’t even have bothered to have used it at all.
We here at Sundicators have a tendency to occasionally use old sayings to assist us in getting our various points across. And to maintain our consistency, we’ll add one here; better safe than sorry.
The Sun’s Harmful Impact on the Skin
Any prolonged exposure to the sun can, and almost always does, result in one or more forms of the sun skin damage that’s caused by that star’s harmful UV rays. Sometimes, the result is the premature aging of your skin. Other times, it’s wrinkles and sun spots. Beyond that, it can cause basic skin cancer or, even much worse, Melanoma. Nobody, and we mean nobody, wants a diagnosis of Melanoma. In fact, when you have a free minute go right ahead and run a search on it. And then you’ll see exactly what we mean.
So when you’re outdoors, let caution be your guide. Even if it hasn’t yet been two hours since your first sunscreen application, the very minute you sense that more is needed, add it. You have absolutely nothing to lose, and everything to gain.
