Moisturisers with Sun protection

More and more customers in the UK are anxious about results of over-exposure to the sun, hence sun protection volume sales increased. Apart from proper Sunscreens intended to use as primary sun protection (when swimming, sun bathing), there is a lot of SPF moisturisers which offers additional benefits. Consumers will link daily SPF products additional benefits such as anti-ageing i.e. wrinkles, improving skin elasticity, protection against age spots / blemishes etc.

Sun protection products are intended to defend the skin against harmful UV rays. UV rays are classified as follows to UVA, UVB and UVC rays [1].

  • UVA – is the longest of the three at 320-400 nanometer. Affects elastin in the skin which leads to sun-induced skin ageing, wrinkles and skin cancer. It penetrates skin deeper than UVB rays, which cause direct damage to supporting tissues.

 

  • UVB – ranges from 290 to 320 nm. It is responsible for inflamed skin and sunburn. It is linked to risk of malignant melanoma and basal cell carcinoma (skin cancer types).

 

  • UVC – is absorbed by the ozone layer and does not reach the earth.

 

Moisturisers that have ability to protect our skin against UV rays contain UV filters. UV filters are chemical substances that are classified in two following categories: synthetic/organic filters that absorb UV radiation, convert it and give it back out as infrared and mineral/inorganic filters which reflect UV radiation away from the skin (shown on picture below [2]). Combination of both types of UV filters should be used in these products for optimum effect.

Moisturisers offering UV protection are called SPF Moisturisers. SPF stands for Sun Protection Factor and “expresses their capacity of protection from erythrema after UV exposure. SPF therefore essentially translates protection from UVBR” – UVB radiation [2]. Moisturiser that claims SPF15 permit to stay in a sunlight 15 times longer than without protection. The SPF can be enhanced by controlling rheology of a product primarily film as If film is too thin, there is not enough coverage. If film is too thick on the other side, it can affect spreadability, therefore balance between coverage and spreadability has to be maintained.

Moisturiser offering UVA protection should have UVA logo on the pack letters “UVA” in a circle shown on a figure below.

It is recommended by European Commission to choose products offering UVA and UVB protection as both UVB and UVA can cause sunburn, skin cancer, and premature skin ageing.
