Application matters   

We’re often reminded of the importance of wearing sunscreen, but we are not always taught how to apply sunscreen correctly. As a result, even well-intentioned routines can fall short – leading to unexpected sunburn despite using SPF. 

In any skincare routine, sunscreen should always be the final step. Allow a few minutes for your previous products to fully absorb before applying your SPF layer generously and evenly.  

It's also important not to mix sunscreen with other products (such as moisturiser) when you apply it, as this can dilute the formula or interact with the SPF ingredients, reducing its ability to protect against UV rays. Altering the concentration of SPF filters compromises the protection it offers, meaning your skin may not be as shielded as you think. 

Apply the SPF at least 15 minutes before sun exposure, and apply it liberally so that it forms a film on the skin when initially applied.  It can be beneficial to apply a second layer of SPF after the initial one to ensure all ‘mountains’ and ‘valleys’ on your skin – such as facial curves, fine lines – are well covered and protected. Imagine you are painting a wall; two coats of paint provide a more even coverage than one. 

Reapplication   

For optimal protection, an SPF should be reapplied during the day. As a general rule of thumb, aim to reapply sunscreen every two hours, especially if you're spending extended periods outdoors or engaging in water-related activities. Sweat and water can compromise the effectiveness of sunscreen, especially when you are also drying yourself/rubbing your skin with a towel, so regular reapplication is essential.   Don’t forget to apply SPF in overlooked areas – the ears, neck, hands, eyelids, lips, and the top of your feet.
