2. Ask a friend or family member to check areas you can't see easily such as ears, scalp and back.
3. Look out for moles or patches of skin that are growing, changing shape, developing new colours, inflamed, bleeding, crusting, red around the edges, itchy or behaving unusally.
4. If in doubt get it checked by your GP or dermatologist.
Clothing should always be your first line of defence against damage from the sun, with sunscreen being used in addition to clothes, including a hat, t-shirt and UV protective sunglasses.
Find the right sunscreen
Use a sunscreen of SPF30 (SPF stands for ‘Sun Protection Factor’) and refers to the level of protection against UVB radiation, linked to skin cancer. Look for a four or ideally five-star UVA rating on the bottle which will help protect from UVA radiation, associated with skin ageing. You may also find that the UVA rating is represented by the letters ‘UVA’ inside a circle. Keep babies and toddlers should be kept out of direct sunlight.
Get your timing right
Skin needs time to absorb sunscreen, so apply generously about 20 to 30 minutes before going out. Re-apply frequently at least every two hours, as it can come off when sweating or through rubbing.
The sun tends to be strongest in the middle of the day, so find some shade typically between 11am and 3pm, especially if you are very fair skinned. Just 10 minutes of strong sunshine is all it takes to burn pale skin.
