Sun Protection: Applying Enough?

Government recommendation that sunscreens with an SPF of 15 are sufficient to prevent sunburn - and the subsequent potential cancer risk -  is based on standard test conditions, not on how much the public use on their skin in reality! During the testing, manufacturers apply 2 mg/cm2 of the sunscreen to the skin but in real life people usually apply much less, only around a quarter to half of this amount (0.5 - 1 mg/cm2) and reduce the protection indicated by the labelled SPF. Therefore, a sunscreen with a high SPF such as 50 will only give an SPF of between 3 and 19. To meet the government recommendation, an adult would need to use 35ml of sunscreen (SPF15) per application. If reapplied every two hours, as is also recommended, a standard 200ml bottle would be used up in two to three days. This is impractical and expensive. Sunscreens carry the ‘Boots star rating system’, which indicates the ratio of UVA and UVB protection. As discussed in a previous blog, the SPF refers to the amount of UVB protection offered and the stars indicate UVA protection; more stars, more UVA protection. UVA makes up more than 95 per cent of UV radiation and contributes to ageing, UVB is the main cause of

Inadequate UVA Protection in Day Moisturisers

Research shows that not all daily moisturising creams that contain UV filters and claim to provide broad spectrum UV protection provide UVA  protection. Day moisturisers are an established part of our skincare routine and skincare manufacturers are increasingly adding UV filters to skin care products as the link between UV radiation and photo-ageing progresses has been proven.   A review of the ingredients of the 29 top selling day creams with claims of broad spectrum UV (using sales volumes from the US website Amazon) assessed the level of UVA protection that could be expected from the product,  looking for the presence of the UVA filters - avobenzone, octocrylene, ecamsule (L'Oreal patented Mexoryl SX) and zinc oxide. 6 of these 29 products contained no active ingredients that provide UVA protection. 7 of the remaining 23 contained zinc oxide but only 3 contained levels greater than 5 % required to provide ‘adequate’ UVA protection. 16 products contained avobenzone but only 3 had adequate concentrations of octocrylene necessary to stabilise the avobenzone, notoriously unstable on contact with UV rays. Although the study notes that further research is needed to investigate the actual UVA protection provided by the products, the researchers conclude that many day creams do not offer long wave UVA protection.

Ageing in the Sun

By |2016-12-07T08:33:53+00:00May 26th, 2010|Skincare Research, Sun Care|

Sun is the dominant factor in the onset of premature ageing! Had we always protected our faces, the way Japanese women often do, our skin would age in a different, subtle way. Ageing with sun protection Our aged face would have a smooth and even surface with only few fine wrinkles. We would be able to distinquish some loss of elasticity (due to thickenned, disoriented bundles) and thinning (atrophy) but no signs of inflammation and only a moderate decrease in perfusion giving our facial skin slightly drawn, pale appearance. The upper skin layer, epidermis, would be still working well in comparison to photo-aged skin. Ageing in the sun (photo-ageing) If we have suntanned all our life, our facial skin will have an uneven (bumpy) surface and sallow, yellowish tone with mottled pigmentation (sun spots). We will see coarse wrinkles and a severe loss of elasticity (due to the thickening of dermis and increase in elastotic amorphous mass, less structural fibres and underlying inflammation). Also the capillaries become prominent on the skin surface (teleangiectasia) contributing to the uneven skin colour. Epidermal changes - and the risk of skin cancer - are also profound. If like me you would rather your face aged in a subtle way, protect your face during the summer.

Sunscreen Application

Topically applied sunscreens protect by absorbing or reflecting radiation at the skin surface. UV filters can be grouped into two broad categories: organic (previously called chemical) and inorganic (previously called physical) (Yaar and Gilchrest, 2007). Organic sunscreens absorb UVR, convert it into heat, and thus prevent photons from interacting with molecules in the skin. Organic sunscreens are usually „invisible‟ and hence cosmetically appealing. Sun Protection Factor (SPF) of a sunscreen is primarily a measure of protection against UVB. It is defined as the minimal perceptible erythema, or minimal erythema dose (MED) ratio between sunscreen-protected and unprotected skin. If a person normally experiences the onset of redness to unprotected skin after 10 minutes of sun exposure, sunscreen with SPF 8 would provide protection against perceptible sunburn for 80 minutes. SPFs are now also categorised as providing low to very high protection: Low protection SPF 6 to 14/Medium protection SPF 15 to 29/High protection SPF 30 to 50/Very high protection SPF 50 + (i.e. SPF 50+). It is recommended that people select sunscreens with SPF 30 or higher (Palm and O‟Donoghue, 2007) because they generally do not apply sufficient quantities of the product. The recommended SPF 30 takes into account these behavioural factors that lead to a reduced level of protection (if applied adequately, then

Stay Safe in the Sun

The tanned face is attractive but over-exposure to the UV light is damaging to the skin cell's DNA and causes sunburn (in severe cases also blistering and pain). Take care and prevent skin cancer (melanoma), now the most common cancer amongst women in their 20s! Stay Safe in the Sun - Avoid the sun during the hottest part of the day, between 11am and 3pm. Find shade under umbrellas, trees or other shelters. - Always cover up, sunscreen alone is not enough. Wear T-shirts, wide-brimmed hats and UV protective sunglasses. - Apply sunscreen generously, also when travelling as sun will still have an effect on your skin through the windows. - Use sunscreen with UVB protection of at least SPF 30 (SPF 50 for children and people with pale skin) and also high UVA protection. - Keep babies and young children out of direct sunlight! *** If concerned about changes in your skin following sun exposure - particular attention should be paid to moles that change in shape, size or colour - consult a local specialist. FaceWorkshops have teamed up with a Consultant Dermatologist, Dr James Britton, at Spire Hull and East Riding Hospital.
