How Sunscreens work
Sunscreens protect the skin from burning by either absorbing the harmful rays or reflecting them from the skin. No sunscreen can provide total protection from all of the sun's rays and that's why it is always important to cover up using appropriate clothing and eye wear especially during the hottest part of the day.
What active ingredient does Surfpase Tinted Sunscreen SPF30+ use?
Surfpaste Tinted Sunscreen uses 38% Non Nano Zinc Oxide which reflects UV-A and UV-B rays rather than chemical actives which absorb these rays.
What does Broad Spectrum mean and is it important?
A sunscreen that provides broad spectrum protection protects against UV-B rays as well as UV-A. All sunscreens protect against UV-B rays which cause sunburn however not all protect again UV-A which causes premature ageing of the skin.
Recent studies have shown that UV-A radiation plays a large role in causing gene mutations that can lead to skin cancer. Therefore it is vital that when using a sunscreen you check that it offers broad spectrum protection.
What is SPF and what protection does it give?
SPF stands for Sun Protection Factor. SPF numbers are an approximate indication of how much protection from the sun the product will provide for your skin. Skin starts to burn after 5 to 10 minutes in the sun. Sunscreen extends that time by a multiple of the SPF e.g if we use an average time of 8 minutes to burn without sunscreen then:
SPF30 sunscreens will protect for 30 x 8 minutes or 240 minutes (4 hours)
SPF15 sunscreens will protect for 15 x 8 minutes or 120 minutes (2 hours)
It is also important to reapply sunscreen every 2 hours or after towelling dry or excessive sweating. This will not prolong the amount of time you can stay in the sun but will ensure the effectiveness of your sunscreen for the remaining time that your sunscreen provides protection.
How much do I need to apply and does it work immediately?
It is important to apply your sunscreen 20-30 minutes before going out in the sun. This allows the sunscreen to reach each layer of the skin and provides maximum protection.
Sunscreen should be applied evenly and liberally to ensure all exposed areas are protected.
Always read the label and use only as directed.
