With SPF now added to everything from moisturisers to foundations, many people assume they’re fully protected from sun damage just by applying their make-up. However, according to Dr Kasim Usmani, a practising GP and aesthetic doctor, multitasking products should not replace proper sunscreen.
The Limitations of Multitasking SPF Products
'SPF moisturisers and foundations do help, but they’re not enough on their own,' he says. 'They are tested in lab conditions using a much thicker layer than people apply in real life, so the protection you actually get is often far lower than the label suggests. Think of them as a bonus layer rather than your main protection.'
If you are relying on a multitasking product, Dr Usmani recommends looking for broad-spectrum protection against both UVA and UVB rays, a minimum SPF 30 (ideally SPF 50), and a high UVA rating such as PA++++ or a high UK star rating.
When Is SPF Moisturiser Acceptable?
That does not mean everyone needs heavy-duty sunscreen every day of the year. In winter, particularly in the UK, UVB levels drop significantly - although UVA rays remain present even on cloudy days.
'On low-exposure days, such as short commutes or mostly indoor days, an SPF moisturiser is reasonable,' says Dr Usmani. 'But for prolonged outdoor exposure, such as long walks, driving or skiing, you still need proper sunscreen. Winter does not mean “no SPF”; it just means being proportionate to your exposure.'
Why Standalone Sunscreens Are the Gold Standard
Standalone sunscreens remain the gold standard because they are specifically formulated to create an even protective film over the skin. They should be applied as the final skincare step after moisturiser, but before makeup, ideally allowing five to 10 minutes to settle before foundation.
For makeup wearers, reapplying SPF throughout the day can feel almost impossible (you do not want to spoil that perfect base!) but Dr Usmani says there are practical ways to top up protection without ruining your look. SPF mists, powders and cushion compacts can all help, although he cautions that sprays should be applied generously rather than as a quick spritz.
'Perfect reapplication is rare,' he says. 'Even dermatologists will admit that. Doing something is better than nothing.'
Commonly Missed Areas
He also warns that some areas of the face are consistently forgotten when applying SPF. The ears, neck, under-eye area and lips are among the most commonly under-protected spots he sees in clinic.
Year-Round Sunscreen Debate
As for the recent debate around whether sunscreen is necessary year-round, Dr Usmani believes the conversation has become oversimplified.
'You do not need to be obsessive with SPF in winter, but daily SPF is still a sensible habit because UVA damage is cumulative all year round,' he says.
And when it comes to children, he is clear: sunscreen should absolutely be part of the morning routine during warmer months. 'Apply SPF 30 to 50 before school, particularly on the face, ears, neck and arms,' he advises. 'Building those habits early is one of the most important things you can do.'
