We have gathered some frequently asked sunscreen questions to make it easy for you to find the FAQs about sunscreen and the best answers to them so you can protect your skin every day.
What is the difference between UVA and UVB rays?
UVA rays are responsible for considerable photo-damage (sunspots, loss of elasticity etc.) because they penetrate deeply into the skin. This damage can be caused without the tell-tale signs of sunburn.
UVB rays are responsible for the sunburn, inflammation and redness. These rays don’t penetrate as deeply as UVA rays but have more energy to cause damage.
How sunscreen works
Sunscreen uses either chemical filters that react with UV light to ‘absorb’ its energy, defending your skin or physical active ingredients to ‘reflect’ the damaging light away from your skin.
Can I get sunburnt in the shade?
You are less likely to get sunburnt in the shade, but UV light can reach you directly and indirectly – so even though you might not get sunburnt, you are still at risk for sun damage and premature ageing.
How much sunscreen do I need for my face?
Sunscreen is tested at an application of 2mg/cm2 – for the average face size, that equals to about a quarter teaspoon.
What is broad spectrum protection?
Sunscreens that offer broad spectrum protection is a quick indicator that it protects and defends the skin from both UVA and UVB rays in a ratio of 0.4:1 UVA to UVB.
Do high number SPFs provide better protection than low number SPFs?
SPF30 is generally recommended by dermatologists as it protects from 97% of the sun’s UVB rays. Higher number SPF absorbs more UVB rays. It’s important to remember that a higher number SPF doesn’t allow you more time between applications and should still be reapplied as often as indicated on the product label.
Should I use a moisturiser with SPF protection daily?
Yes. You’re exposed to the damage causing UV-rays of the sun year round.
Do I need to take extra precaution in the sun if I’m taking medication?
An increased sensitivity to sun exposure is a side effect of many types of medication including antibiotics and certain blood pressure medicines and anti-depressants. Your physician will be able to advise you on the best care to take when in the sun.
At what age should my baby begin wearing a product with SPF?
Direct sunlight should be avoided by babies under the age of 6 months. Babies should be kept out of direct sunlight, protective clothing, sunglasses and a hat with a brim should be used. Keep babies out of the sun between 10:00 and 15:00. For babies 6 -12 months sunscreen should be used. Limit exposure times and use protective clothing, hats and sunglasses.
