Risks and Complications

While the benefits of using a sunscreen are untold, that does not mean their use is without some risk, however minor. Some sunscreens can irritate your skin causing irritant contact dermatitis, a direct result of applying an ‘irritant’ to your skin; allergic contact dermatitis, skin inflammation caused by a hypersensitivity reaction, acting through the body’s immune system, to a particular substance or group of related substances, or photo-allergic contact dermatitis, where the allergic reaction is caused by the combination of the irritant and sunlight. Some people are also allergic to an ingredient used in sunscreens known as PABA (para-aminobenzoic acid) however many sunscreens are now PABA free. If you are worried about having an allergic reaction, a dermatologist can do a patch test for you to advise you on what type of sunscreen you should be using. If you have not done this but have developed a rash from using a sunscreen visit your GP or dermatologist who will be able to help you. Another risk is using out of date sunscreens. It is advisable to buy new sun protection products every year before you go on holiday as if the product has gone ‘off’ it will not be effective in protecting you from UV radiation. Check the ‘used by’ date on the product to make sure.
