Have you been getting sun protection wrong all along?

You may think that just putting on a high factor of sun lotion will keep you safe from the sun's rays, but you'd be wrong. Reduce skin ageing and protect yourself from skin cancer with these tips for using sun lotion correctly.

Spending time in the sun is great for mental wellbeing, but it’s essential to respect the sun’s power and protect your skin properly. Here's what you need to know:

1. Use lotion that protects from both UVA and UVB

Ultraviolet radiation (UV) damages the skin’s cellular DNA, which can cause both short-term and long-term damage. UVA and UVB are the two kinds of UV ray that affect us on the Earth’s surface. Both can damage our skin and can cause cancer. But many lotions only protect you from UVB radiation and SPF (skin protection factor) is only a measure of how well the lotion will protect you from UVB light.

To make sure you are protected from both UVA and UVB check the bottle for a star rating, which is the measure of UVA protection. Three to five stars will protect you sufficiently. Look for the term ‘broad spectrum’ which means the lotion protects from both UVA and UVB.

2. Apply top to toe

Sun damage can affect any bit of skin, so make sure you use lotion on all exposed skin. Put it on before you get dressed in the morning so that you don’t miss any bits. Don’t forget the tops of your ears, back of your hands and your hair parting if you have one.

3. Reapply regularly

All lotions can rub off and and even if they claim to be waterproof most won’t resist the rubbing from your towel when you dry yourself. So as a rule reapply after every dip in the water, after playing sports or sweating and at a minimum every two hours. Bold features like noses, brows, ears and cheek bones may need more regular application.

4. Use a minimum of factor 30

The higher the factor, the greater the protection from UVB rays as long as you follow the above advice. It may be tempting to use a lower factor to achieve a tan, but in reality this will only damage your skin and could lead to burning. Particularly if your skin hasn't seen the sun in a while it's important that you use a high factor (40 to 50), which can be reduced to 30 after a week.

Children should always wear factor 50 as their skin is much more delicate than an adults, and more vulnerable to burning.

A UVA protection factor of three to five stars will provide adequate protection from UVA rays. 

5. Wear sun lotion even if you cover up

Many people think they don't have to wear sun lotion if they are covered up in clothes. In fact, many fabrics will not protect you from the sun's rays. UPF is a rating of sun protection for clothing and other fabrics. Lighter fabrics, which are more popular in sunny months typically have a lower UPF rating, and are less protective than heavier fabrics. So it's important that you apply sun lotion even if you cover up.
