3 thumb rules:
Always apply sun lotion or spray at least 20 minutes before sun exposure allowing your skin to time to absorb this protective cover. After twenty minutes in the sun, reapply the sunscreen to help ensure even and complete coverage.
You should reapply sun protection regularly, especially after swimming or towelling.
Avoid intensive midday sun.
10 thumb rules:
Know your skin type and protect yourself accordingly. Everyone should take it easy for the first few days of exposure. Let your skin get used to the sunshine progressively.
Don't stay out in the sun between 11am and 3pm. The sun's rays are less intense early in the morning and late in the afternoon.
Use a sunscreen that's appropriate to your skin type and to the level of sun you're exposed to. The lighter your complexion, the more slowly you should increase your exposure time.
Take extra-special care with your kids. Make sure they wear caps, light-coloured T-shirts and sunglasses. Little ones need frequent applications of sunscreen on all parts of their bodies. Playing in the sand and running in and out of the water can wash away the sunscreen. Babies should not be left in direct sunlight; their skin and eyes are ultra sensitive!
Most skin damage occurs when you are a child.
Remember to apply and re-apply your sunscreen when exercising or playing sports in the sun. Perspiration causes sunscreen run-off!
Stay away from surfaces that reflect sunlight back at you - or else increase your sun protection. Snow, ice, sand, white cement all increase the effects of UV rays. Did you know that most UV rays can "dive" down into the water? It's a fact to keep in mind when you take a dip or paddling about.
Self-tanners are a great cosmetic aid, however many of these products offer no sun protection at all! The "tan" they produce won't block out any UV rays.
Keep out of the sun altogether if you are taking medicine that contains photosensitizing compounds (ask your doctor to be sure).
If you should experience severe sunburn, especially blistering burns, consult a doctor without delay. A bad sunburn always requires medical attention.
Be sure that your sunscreen contains both UVB and UVA filters. Although UVA's don't "burn" the skin, they penetrate deep into the skin's lower layers where they do considerable damage. UVB's, which are most intense when the sun is at its zenith, are chiefly responsible for sunburn.
How do you pick the right sunscreen for you?
Look for a product that combines these three essential features:
A broad-spectrum formula - one that filters long and short UVA's as well as UVB's
A formula that won't break down and lose its power in sunlight - in other words, a formula that's photo stable.
Protective formula with a SPF of 15 or higher.
An ideal sunscreen formula must also be:
Water resistant
Easy and pleasant to apply - otherwise you probably won't use it, or won't use enough!
SPF 10...25...40... What do the numbers mean?
Your sunscreen's Sun Protection Factor indicates the level of protection it affords against sunburn. The numbers make it easier for people to choose the sunscreen best suited to their complexions and conditions of exposure.In broad terms, you can say that an SPF of 10 or under is Low
Between 10 and 20 Medium
Between 20 and 40 High
Over 40 Very high
It is a good idea to wear a high SPF on nose and checks when sunbathing and that wearing lip balsam to avoid cracking lips.
Use sunscreen for protection, not to stay out longer in the sun!
