Blue water testing of Active Sunscreen
Racing a yacht from Auckland to Fiji this year we faced all conditions from gale to dead calm. In a small boat in the open ocean you are kept busy and it is really easy to neglect yourself, often with serious consequences. You need daily routines that include food, water, sleep and protection from the sun, miss out on any one of these and you become a liability to the rest of the crew and the safety of the voyage. Once a day every morning I applied Active Suncream on arrival, 11 days later, not even my nose was burnt! Better still there was no sign of the rash I typically get from other suncreams. Geoff Bates Yachtsman.
Current emulsion based sunscreens do not provide adequate UV protection and the main reason for this is that the film they produce on the skin is too thin. It is because of this widespread deficiency that sunscreens commonly carry the instructions to reapply these water-based emulsion sunscreens every two hours. More than this, sunscreen users are faced annually with the slip slop and slap campaign. Undisguised advice to apply the product in liberal quantities which are frequently messy. Users are also advised to wait 30 minutes, after application before venturing out into the sun.

Dear Sir,
People writing about sunscreens (Health, Oct.30), could pay some attention to teasing out what the sun protection factor really implies. A little simple arithmetic can clear away decades of misinformation. SPF has no dimensions; it is the ratio of two other numbers. When we see where these have come from, we are on the way to a better
understanding. The standard SPF test involves using a UV lamp to produce a mild burn on a volunteer's skin. (Even a mild burn has been shown to produce precancerous damage). For example, if it took two minutes to burn skin that had been coated with a measured amount of sunscreen, and four seconds to produce the same burn on coated skin, the SPF would be 120/4 ie. 30. Human skin, depending on the skin type and the time of day, takes about fifteen minutes in the sun to become red. We are often told that we can multiply the SPF by this time to calculate how long we can safely stay out in the sun, eg. 30 x 15 minutes, or seven-and-a-half hours. But, as Joanne Black told us (The Black page, January 10, 2009), if using the SPF 30+ product she named, we should reapply it, not every seven-and-a-half hours but every two hours.
What has gone wrong? Why the discrepancy? The UV lamp, being so much more powerful than the sun, required only two minutes; not much of a rehearsal for hours out on the sports field. That is the explanation; as far as sunscreens are concerned, real life and the laboratory are very different places. In other words the SPF test doesn't tells us how much protection we will still be getting during actual use, moving and sweating. Some products stay on the skin better than others.
