Neal Rimmer, Which? scientist, advises: 'There are strict regulations defining what qualifies as a sunscreen. Products such as moisturisers, lip balms and hand creams with SPF aren't classified as sunscreens; they're cosmetic products that include sun protection. In the industry, these are increasingly referred to as “secondary sun protection” products, reflecting that their primary function is not sun protection, but skincare.'
'As a rule of thumb, products that provide detailed guidance on reapplication and limiting sun exposure are more likely to be sunscreens. Look for the logo, a standardised European mark confirming that the product provides an approved level of UVA protection. Sunscreens are also required to display an SPF protection category – – helping consumers understand the level of UVB protection the product offers.'To help you protect your face and body, we spoke to Dr Angela Tewari, Consultant Dermatologist and British Skin Foundation spokesperson.
Read her expert advice and her answers to commonly asked questions about SPF lip balms, best moisturisers with SPF and SPF hand creams, including how they compare to sunscreen and how much product you actually need to adequately protect your skin from sun damage.
Lip products with SPF
The beauty aisles offer an endless array of ways to shield your pout: protective lip tints, SPF lip oils, balms, and flavoured options now all have added sun protection.
Common claims include high-level protection against UVA/UVB rays, lasting moisture, deep hydration and soothing benefits for dry or chapped lips. But do they work?
Are SPF lip balms worth it?
Dr Tewari says: 'Yes. Any form of barrier protection (lanolin, glycerol, beeswax) is really helpful for lip skin barrier protection, as the stratum corneum (the top layer) is thinner. Thus, there is more water loss from the skin, and the lips can quickly feel dry and cracked.
'Add in an SPF (UVB and UVA cover), and you get that protection from the UV rays. The answer is that an SPF lip balm is so worth it. Now we have filters that can be added to give an SPF50.'

Initial applicationReapplicationHand creams with SPF
Your hands may not be the first area of your body you look to protect on a sunny day, but the skin on your hands is actually exposed to the sun more than almost any other part of your body, making them one of the first places to show premature ageing and sunspots.
Common claims include protecting your hands from UVA and UVB rays, while helping to soothe dry skin and reduce visible signs of ageing.
What is the difference between hand cream with SPF and sunscreen?
Dr Tewari says: 'A hand cream with SPF is a moisturising hand product that also contains UV filters. Sunscreen is usually designed to form a uniform, durable UV-protective film on the skin and is more likely to include water-resistance claims.
'The SPF number still depends on the same principle: enough product must be applied. SPF testing is based on 2mg/cm² of product on the skin.'
Neal Rimmer cautions that the 'amount used in laboratory testing is typically much higher than the amount most consumers would apply in real life'.
Hand creams may also include ingredients that help strengthen nails, such as panthenol or cuticle oils, if your nails are brittle or your cuticles are dry. Moisturising ingredients such as glycerin, hyaluronic acid, ceramides, shea butter and aloe vera can help very dry or cracked hand skin. In some cases, you may need two products rather than a one-size-fits-all option. On sunny days with a high UV index, top up with a separate SPF30 or SPF50 sunscreen if your hand cream doesn't include one.

Initial applicationReapplicationMoisturisers with SPF
From hybrid products that are somewhere between moisturisers and sun creams, or moisturisers and foundation, to plenty of products with added sun protection that claim to be useful for more than one thing. Tinted moisturisers with SPF are a popular option, as they're a lighter alternative to foundation; in theory, you might use a little more.
Does SPF moisturiser count as sunscreen?
'Applying foundation first and a spray sun cream on top is a good option; application order is variable and tailored to each person and their skincare routine. Using sun protection and finding strategies that suit you (wearing a hat, sunglasses, wearing long-sleeved breathable clothing, for example) is much more important than in what order you apply your products.'
'Plus, for the SPF claim in the UK, SPF-labelled moisturisers are tested using sunscreen-style SPF methods in a lab.'

Eye creams with SPF
There are significantly fewer SPF eye cream options than for other products with added sun protection. However, you can find dedicated SPF brightening creams or hybrid products, such as SPF sticks, for use on the face, lips, and eyes from various skincare brands.
Do any SPF eye creams work?
Dr Tweari advises: 'Eye creams with SPF can work if they contain properly tested UV filters and are applied generously enough.
'The main advantage is not necessarily that they are stronger than regular sunscreen, but that they may be more tolerable around the eyes. This is related to the product's pH. For people whose eyes sting with regular sunscreen, a dedicated SPF eye product may help them protect the eyelids and under-eye area more consistently.'
What do you need to look for in an eye cream with SPF?
Dr Twearis says: 'Look for SPF 30 or higher, broad-spectrum or UVA protection, and a formula designed to be used around the eyes. Fragrance-free or low-irritant products are preferable if you are sensitive. “Ophthalmologist-tested” or “ocular tolerance tested” can be helpful, although it doesn't guarantee zero stinging.
Mineral filters such as zinc oxide or titanium dioxide may be better tolerated by some people, also the broad band filters mexoryl, tinosorb and triasorb.'

They can, however, complement your sun protection routine and may provide sufficient protection when UV levels are low, such as during the autumn and winter.'
