Our reader Rachelle asked:

I heard that we’re supposed to reapply sunscreen throughout the day. Am I supposed to remove my makeup in the middle of the day and apply sunscreen again?


If you are indoors, one application at the start of the day is sufficient to protect your skin against the UV rays. But if you are heading outdoors, it is recommended to re-apply your sunscreen generously once every two hours, or after swimming, sweating or towel drying.

The re-application of sunscreen helps to ensure an optimal level of protection. During the course of the day, friction with clothing, sweat or water from the sea or swimming pool removes sunscreen from your skin. To keep an adequate level of protection, re-application is necessary.

How much sunscreen should we apply?

The amount of sunscreen to wear depends on the shape and size of your face. The recommended usage for sunscreen application is two milligrams per square-centimetres of your skin. This works out to an average of 2 teaspoons worth for the entire body.

Sunscreen should be applied daily, even on cloudy or rainy days as long as UVA rays are present all year round and can pass through clouds. These damaging UVA rays penetrate the skin deeply to the dermis layer and can cause serious damage, both in terms of skin’s colour (graying), structure (wrinkles, sagging) and immune system (drop in immune defences).

How should we re-apply sunscreen?

When you are re-applying sunscreen, make sure that you apply liberally and evenly on your face/body so that every part is covered. Pat gently instead of rubbing the sunscreen into your face or body. It is also important to apply sunscreen at least 20 minutes before the first sun exposure.
