Sunblocks - stop UV rays penetrating the skin by adding a layer on the skin surface.



Sunscreens - penetrate to deep layers of the skin and reflect harmful rays.

The key to selecting an effective sun protection product is to understand the ingredients in the products, and how they work based on the activities you engage in.

There are two types of UV that harm your skin:

UVA - damages the inner layers of the skin and causes wrinkles and lines, and skin cancer.

UVB - the most damaging radiation, burns the skin and damages the skin cell DNA, resulting in long term skin disease.

Most sunscreens protect from UVA damage, but only broad spectrum sunscreens protect both from UVA and UVB. These are the ones to look for.Previously, those products that protected from both UVA and UVB were referred to as 'Sunblocks'; and those that protected the skin from UVA, referred to as 'Sunscreens'.

Many consumer bodies around the world are now banning manufacturers from referring to their broad spectrum sun protection products as sun blocks, unless they work in the manner as outlined above.

This has just added confusion to the market for consumers - hence the need to fully understand the ingredients in the products.

Overall you are aiming to use a sun protection product that:

• Maintains its effectiveness for the duration



• Is easy to apply and does not stain clothing.

So next time you slip, slop, slap, take a minute to read the label of your sunblock or sunscreen lotion and ensure you are getting all the sun protection you thought you were.

Sunblocks and sunscreens differ considerably in their sun protection. Are you really getting the protection the advertisements claim?
