The most important step in skincare: best practices for using SPF 

The sun is a powerful source of vitality and energy – but without the right protection, it can also be one of the greatest contributors to skin damage. UV rays penetrate the skin, breaking down collagen and elastin, accelerating the formation of fine lines and wrinkles. They can also trigger excess melanin (pigment) production, leading to hyperpigmentation, dark spots and uneven skin tone – and, over time, increase the risk of skin cancers. As awareness grows around these long-term effects of sun exposure, broad-spectrum SPF has become a non-negotiable part of any skincare ritual. No longer reserved for summer holidays, sunscreen has rightfully earned its place as a daily essential for protecting skin health year-round.

The most important step in skincare: best practices for using SPF 

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.  

“Daily SPF supports your skin’s own regenerative processes – protecting the collagen, elastin, and cellular integrity that help to keep it in optimal health for years to come.”

Seek shade  

It’s important to remember that SPF alone doesn’t offer complete protection. No sunscreen can block 100% of UV rays.  For example, SPF 15 filters about 93% of UVB rays, SPF 30 blocks around 97%, and SPF 50 offers approximately 98% protection. While the difference may seem small, those few percentage points can add up over time, particularly with daily exposure.

This is why seeking shade — especially during peak sun hours — is so important. Whether you're spending time outdoors or simply going about your day, try to minimise direct sun exposure when UV levels are highest, and wear protective clothing like long sleeves, a wide-brimmed hat, and sunglasses whenever possible. 

Out with the old, in with the new   

Just like the seasons change, so should your sunscreen. The effectiveness of sunscreens can diminish over time due to factors such as exposure to heat, air, and light. To ensure you're getting maximum protection, consider investing in a new sunscreen at the start of each season. Make sure to check the expiration date on your sunscreen, this is indicated on the packaging. Using expired sunscreen may compromise its efficacy and could result in inadequate sun protection. Also keep the SPF vessel out of excessive heat and direct sunlight.
