Remedies for common family ailments: 5. Sunscreen creams and lotions

Prolonged exposure to strong sunlight significantly increases the risk of skin cancer. Sunscreens provide useful protection from sunburn if correctly used. Some sunscreens contain chemical compounds which work by absorbing UVB wavelengths. Others contain chemicals which act as reflectants of UVA waves, eg titanium dioxide. Stars on the packet indicate how much UVA protection the product provides-the more stars, the more protection. Products are labelled with their sunscreen protection factor (SPF). The higher the factor, the greater the protection. Products used on children should have an SPF of at least 15. Fair-skinned and freckled people also need a high SPF as they burn easily. Use products according to the manufacturer's instructions and reapply at intervals and after swimming. Some products combine sunscreen properties with being water resistant perspiration-resistant or insect-repellent. Avoid folklore remedies like coconut oil. It is better to go or a scientifically formulated, branded product. A properly formulated after-sun lotion is advisable in order to counteract the drying effects of the sun on the skin.
