AETHIC’S NEW VOLUNTARY PHOTO-STABILITY SUNSCREEN LABELLING ANNOUNCED.
– AETHIC FOUNDER FED UP OF MISLEADING LABELLING ON SUNSCREEN HAS CREATED HIS OWN AND URGES OTHERS TO FOLLOW SUIT.
The under-reported photo-stability aspect of sunscreens is to get greater
prominence on-pack with a rating system proposed by London-based skincare
Photo-stability indicates how quickly a sun filter degrades when exposed to sunlight. Photo-unstable filters degrade quickly leaving skin vulnerable to burning and skin damage after a relatively short time, while photo-stable sun filters work better for longer.
The proposed labelling system declares the remaining protective efficacy of sun filters after 120 minutes of sunlight exposure in constant laboratory conditions.
Obligatory SPF ratings, which relate to UVB protection only, are useful, however, they do not convey a complete picture. UVA protection is equally important as is a product being water-proof and actually staying on. Yet none of this matters if the active ingredients, the UV filters themselves, are degrading too fast.
While scientists working on sun protection regularly research and report on the photo-stability of ingredients, the consumer has seldom had access to this
important information when selecting which product to buy.
Prof Paul Long, an expert in Marine Biotechnology and Therapeutics at King’s
College London, who has done considerable work on naturally occurring sun filters, says: “It is high time that the industry reports to consumers on the photo-stability of sun filters in a comprehensible way.”
Adds Aethic CEO, Allard Marx: “People deserve to know how photo-stable the products on offer are and this voluntary labelling system goes some way to achieving that. We will, of course, be adopting it ourselves in our next production runs, later this year.”
