Do SPF moisturisers offer enough protection?
A moisturiser with SPF can provide effective protection – but only if you apply enough. “You have to apply quite a large amount, otherwise you don't get sufficient amount of protection,” Dr Laftah explains. “Studies often demonstrate that most people apply less than what's expected on the bottle with sunscreen and even less when it comes to moisturisers.”2 To get the full benefit, she recommends using around two finger lengths of product (roughly half a teaspoon) for your face, neck and ears.
SPF moisturisers are great for everyday use – particularly on lower UV days or when you’re mostly indoors. As Dr Laftah explains, “If you're indoors most of the time but sitting next to a window, or you just have a short commute, an SPF30 moisturiser should be absolutely fine.” However, for longer periods outdoors, holidays (including
festivals) or when the UV index is high, a dedicated sunscreen (SPF 30-50) is still recommended.

Dr Laftah also notes that while UVB exposure is lower in winter, UVA rays can still penetrate through clouds and contribute to long-term skin damage. “We know that UVA contributes to fine lines and
wrinkles forming. If you want to reduce that progression, wearing sunscreen is really important.” She adds that for those with delicate skin,
pigmentation concerns or a family history of skin cancer, using a broad-spectrum sunscreen year-round may be the better option.
Finally, if your skin needs extra hydration, it can be worth separating the two steps. “If you feel like your skin requires extra hydration, then I would opt to separate the two. Have a really good moisturiser, then follow with sunscreen.”
