With the alarming numbers of skin cancers being diagnosed around the world, it is increasingly evident that people of all colours need protection from ultraviolet radiation.
Protection should start from a young age and continue through your life. Please always ensure you check with a physician for children under 6 months.
SPF = Sun Protection Factor which specifies on your bottle of sunscreen how much protection your sunscreen offers against UVB rays.
In general, the higher the number, the greater the protection.
- SPF 6, 8 and 10 = Low Protection
- SPF 15, 20 and 25 = Medium Protection
- SPF 30 = High Protection
- SPF 50+ = Very High Protection
This is measured using a standardised test.
The SPF number indicates how many times longer you can stay in the sun before starting to burn. The way it works is that you take the number of minutes it normally takes your skin to burn in the sun with no protection (let’s say 15 minutes). Then, you multiply that number by the SPF number (in this case, factor 6). Since 15 x 6 = 90, you should have 90 minutes before you start to burn. In other words, the higher the SPF the greater the protection. But remember these are theoretical values. In reality the time depends amongst other factors on your skin photo type and the local UV intensity. You should always reapply every 2 hours or after swimming, sweating or toweling.
To choose the right SPF, you need to consider several factors. The most important of these is your skin’s phototype, which includes the colour of your skin before exposure to the sun, your hair and eye colour and other factors. You also need to think about where you are going on holiday and what time of year it is.

The sunlight that reaches us is made up of two types of harmful rays:
- Long wave ultraviolet A (UVA). These rays can age us.
- Short wave ultraviolet B (UVB). These rays can burn us.
Overexposure to either can damage the skin. There’s also a third type of ray, UVC - these are the shortest and strongest, but thankfully they’re absorbed by the ozone layer and don’t typically reach the Earth.
UVA rays penetrate deep into the dermis, the skin’s thickest layer. Unprotected exposure can lead to premature skin ageing and suppression of the immune system. And when your skin’s ageing defenses are down, you’re at risk of skin cancer.
UVB rays will usually burn the superficial layers of your skin. The intensity of UVB rays vary by season, location and time of day, with peak hours from 10am to 4pm. Sunburned skin doesn’t just feel awful, it can cause permanent damage over time.
All EU Sun Protection products have a ‘Period after opening (PAO)’ indicating how long the product is safe to use after opening by the consumer.
Our Hawaiian Tropic TM products contain a PAO of 12 months after opening. This means that we recommend any bottle that is left over after one year of opening, should be replaced to ensure you have the highest standard of protection and quality.
The Skin Cancer Foundation, founded in 1979, endorses a wide range of Hawaiian Tropic TM Lotion and Oil products with an SPF 15 and above, due to the high levels of UVA & UVB protection they provide. This organisation dedicates itself to reducing the incidence of skin cancer through a combination of research, public education and awareness.
