If you saw a sunscreen that was marked ‘SPF30’ and one that was ‘SPF30+’, which do you think would be the better sunscreen? Asking yourself whether that’s a trick question, you’d be correct, strangely, it’s the SPF30. I don’t intend to cause a panic with this statement, they’re both providing 30x more protection than unprotectedContinue reading “SPF30+ vs SPF30 a sunscreen showdown”
There has been increasing consumer concern over the use of ‘chemicals’ in everyday products, as a consequence, there has been a surge in the number of do-it-yourself or homemade products being publicized on-line. Sunscreens are no exception to the DIY craze, but are these products all they’re cracked up to be? In short, the answerContinue reading “The dangers of DIY sunscreen”
Despite high SPF50+ sunscreens on the market that are capable of providing hours of protection from sun damage, it’s an unfortunate reality that people continue to become sun burnt while wearing sunscreen. The reasons why we’re still getting sun burnt are simple – we aren’t applying enough sunscreen to properly protect ourselves. Having done someContinue reading “More is more, how much sunscreen is enough?”
I’ve always had reservations about the use of aerosol* based sunscreens since I had heard reports of people accidentally setting themselves on fire in the United States. Having seen an increased number of product performance complaints about aerosol based sunscreens, I had serious doubts about the ability for these products to achieve the claimed sunContinue reading “Can aerosol sunscreens cause more harm than good?”
SolarD sunscreen was introduced into the Australian market in late 2014, advertised as being a technologically advanced formula that permits the particular wavelengths of ultra-violet light that your body uses to naturally produce vitamin D. The concept for this product is new and no doubt of interest to consumers with the increasing concerns over their vitamin DContinue reading “SolarD, Vitamin D and Sun Protection”
With the introduction of SPF50+ sunscreens into Australia in late 2012, early 2013, there had been, and continues to be, a belief by some (including some fairly reputable organizations), that there is a negligible increase in protection as compared to previous generation SPF30+ sunscreens. Given SPF is the acronym for ‘Sun Protection Factor’, logic should prevail that 50+ provides considerably better protection than 30 and it is, twice as good in fact!
The articles that have been written dismissing SPF50+ will always raise a supposed minor change in protection by referring to a “1.3% increase in protection” which is an incorrect representation of a factual figure. There is a 1.3% increase, however the increase relates to the absorbance, where SPF30 sunscreen absorbs 96.67% of UVB radiation (and plenty of UVA also), whilst SPF50 sunscreen absorbs 98.00% of UVB radiation (SPF50+ actually absorbs over 98.33%). If we presume an SPF30 sunscreen was to provide 300 minutes of protection, an SPF50 sunscreen certainly does not offer a paltry additional 3.9 minutes in the sun (300 minutes multiplied by the supposed “1.3% increase in protection”).
