Sunscreens

Applying sunscreen

Checking the skin for a reaction …

Different sunscreens are usually made with different ingredients and care needs to be taken in case your child has a reaction to it. We recommend testing for any skin reactions using the “self patch test” before applying it onto larger areas of the body. To do this, rub some of the sunscreen onto a small patch of skin on the inner elbow daily for a few days, up to 2 weeks. You should be on the look out for any skin changes – including redness, blistering, raised swelling or hives, flakiness or itching of the skin. Avoid any sunscreen that causes any of these skin reactions or allergies.

How much to use…

Use generous amounts of sunscreen, at least half a teaspoon to each of your child’s arms, legs, front and back of the body, and to the neck and head.

When to apply…

Ideally sunscreens should only be used in children older than 6 months of age. Apply the sunscreen at least 20 minutes before going outdoors. Remember to reapply it every 2 hours and/or after any water activities such as swimming or playing in the water or if there has been excessive sweating.

Choosing the right sunscreen

We recommend…

We recommend sunscreens that have a high ‘Sun Protection Factor’ (SPF) that is, SPF of 30 or more, are ‘broad-spectrum’, and are water-resistant. Current standard is SPF 50 +, so this is ideal. For toddlers and children with sensitive skin, it is best to use sunscreens that use minerals like zinc oxide or titanium dioxide and those that are preservative free.

Should I use sunscreen sprays, lotions or sticks?

Lotions are easy to apply. Although sprays and sticks are a fun way of applying sunscreen in children, they can make it difficult to ensure adequate coverage of all skin surface. Ultimately, it's important that you choose whichever type that will make it easier for you and your child to apply sunscreen without too much fuss or resistance.

What is SPF?

It is a number that tells you how well and for how long your sunscreen protects you and your children from the sun’s harmful rays. The larger the number, the better the protection.

What is broad spectrum?

There are two main types of sun rays that can be harmful to your child called ‘UV-A’ and ‘UV-B’ or ultraviolet A and ultraviolet B. Broad-spectrum means that your sunscreen will help protect your child against both of these harmful rays which is important in preventing skin cancers.

What does ‘water resistant’ mean?

Sunscreens that are labelled ‘water-resistant’ are less likely to wash off when your child comes into contact with water after applying the sunscreen. It is still very important however to keep reapplying sunscreen every 2 hours or after water based activities.

Tips for parents

Choose the sunscreen that you know your child will use.
Teach your child how to apply sunscreen – make it part of their routine.
Be the role-model for your child in sun protection by using it yourself.
