The ultimate sun protection guide for your next tropical escape

September is here. And, if you have yet to take a proper break this year, consider this your cue to use those annual leave days.

Singapore Airlines can take you straight to the beaches of Bali and Phuket, the coastline of Danang or the islands of the Maldives, where swimming, snorkelling and long days outdoors offer a welcome change from desks and air-conditioned spaces. After all, The World Health Organization notes that time in natural environments can support mental wellbeing and encourage physical activity and relaxation.

There is just one thing to be mindful of while enjoying all that time outdoors: the sun.

Tropical UV levels can remain high throughout the year, while sand and water can reflect UV rays. Some UV can penetrate the water’s surface. In other words, swimming and snorkelling do not necessarily give your skin a break.

And don’t judge your exposure by how hot it feels. “UV exposure occurs even on overcast days and in cooler weather,” says Dr Rachel Ho, aesthetic doctor and medical director of The Skin Longevity Clinic.

A destination that feels cooler or less humid than Singapore isn’t necessarily gentler on your skin. Sun protection isn’t reserved for days spent in swimwear by the water either.

Warmer climes naturally call for lighter dressing, from sleeveless silhouettes to shorts and breezier layers worn while sightseeing, exploring or dining outdoors.

With more skin exposed, UV protection becomes just as relevant away from the beach.

It’s worth knowing what the numbers and letters on your sunscreen actually mean. SPF primarily measures protection against UVB, the rays responsible for most sunburn and which also contribute to skin cancer.

SPF 30 filters approximately 97 per cent of UVB rays and SPF 50 around 98 per cent when properly applied, Dr Ho explains. For most situations, she says SPF 30 is sufficient, although a higher SPF makes sense if you expect prolonged or particularly strong sun exposure.

UVB is only half the picture. UVA rays penetrate more deeply into the skin and contribute to pigmentation, premature skin ageing and skin cancer. “Broad spectrum” means a sunscreen protects against both UVA and UVB.

You may also see a PA rating, particularly on Japanese and South Korean formulas. Short for Protection Grade of UVA, it indicates the level of UVA protection and runs from PA+ to PA++++. Put simply, the more plus signs, the greater the protection.

Choosing the right sunscreen is one thing. Using it properly is another.

Before heading to the beach or setting off for a morning of island-hopping, apply it generously. “Most people apply far less than the recommended amount,” says Dr Ho, who advises approximately two tablespoons for full-body coverage. Don’t overlook easy-to-miss areas such as the lips, ears, neck and feet.

Then comes the step many people forget: reapplication. Dr Ho recommends topping up every two to three hours when you’re outdoors, and more frequently when water is involved.

If you’ve been swimming or snorkelling, reapply after towelling off and follow the directions on your water-resistant sunscreen. Water-resistant, after all, does not mean waterproof.

As for mineral versus chemical sunscreen, there is no need to overthink it. Mineral formulas typically use zinc oxide or titanium dioxide and can be thicker or leave a white cast, while chemical sunscreens tend to feel lighter and more transparent.

Dr Ho’s advice is to choose “the one that you prefer based on your skin type and cosmetic needs so that you’ll apply and reapply sufficiently” – because the best sunscreen for a day spent swimming, sailing or stretched out on the sand is ultimately one you will keep using.

And because “no sunscreen is fail-proof”, add shade, umbrellas, sleeved or UPF clothing and SPF lip balm where practical. Then get on with enjoying the sun, sand and sea.

Ready to pack your beach bag? Here are the sunscreens worth packing for your next tropical escape.

What it is

A peach-tinted, tone-up sunscreen made with 75% hydrating essence that pairs high UVA and UVB protection with the instant brightening effect of a sheer complexion base.

Designed for dull, tired-looking skin, it leaves the complexion looking fresher and more radiant without reaching for foundation.

Key ingredients and benefits

Why should you get it for a tropical holiday

Hot, humid mornings are when layers of skincare, sunscreen and foundation can start to feel excessive. This covers several bases at once: sun protection, hydration and a subtle peach-toned boost that makes tired skin look fresher. Wear it alone when you want to skip foundation, or use it as a smooth, lightweight base under makeup.

Available at JUNGSAEMMOOL Flagship Singapore at 27 Scotts Road, ION Orchard and VivoCity. Online at JUNGSAEMMOOL Beauty Singapore, Shopee and Lazada.

This combines SPF50+ PA++++ with a nourishing cream that keeps skin moisturised for up to 10 hours, making it useful when your day moves between strong sun and air conditioning. Argan oil helps prevent dryness, while the skincare ingredients target concerns such as dullness and fine lines. A good option when you want your sunscreen to do the job of a rich daytime moisturiser too.

Available at Clé de Peau Beauté boutiques and counters in Singapore. Online at Clé de Peau Beauté Singapore, Sephora, Metro and Takashimaya.

Why should you get it for a tropical holiday

If keeping your T-zone in check becomes a losing battle in tropical humidity, this is one to pack. Its up-to-12-hour shine control helps keep excess sheen at bay, while the pore-blurring finish doubles as a primer if you plan on wearing makeup. Think sightseeing, outdoor lunches and long days exploring when you want your SPF to leave skin looking polished rather than progressively shinier.

What it is

A lightweight, very water-resistant SPF50+ PA++++ lotion for both face and body, designed to keep its protective layer more consistent as you move through the day.

This is the SPF for the holiday where you’re actually going to be outside.

Think hiking in Bali, cycling around an island or spending the day hopping between beaches: heat, sweat and water are exactly the conditions SynchroShieldRepair is designed to respond to.

It is also very water-resistant and suitable for face and body, so you can streamline what goes into your beach bag without compromising on SPF50+ PA++++ protection.

Available at Shiseido boutiques and Sephora stores. Online at Shiseido, Sephora and Shopee.

What it is

A hydrating physical sunscreen for those who like the gentleness of a mineral SPF but not the thick, chalky finish that can come with one.

It’s a clever bit of synergy for tropical holidays, where the elements become part of how the formula performs. And despite its super-waterproof credentials, the gel feels refreshingly light and non-sticky, making repeat applications throughout the day that much easier.

The lightweight, fast-absorbing texture makes its nourishing formula a good fit for the tropics, delivering hydration and antioxidant support without feeling rich or heavy on the skin.

• Non-comedogenic formula: Designed not to clog pores.

Why should you get it for a tropical holiday

This is the one you keep in your bag, not your bathroom. Tropical days have a way of turning even the most polished morning face shiny by lunchtime, and reapplying a cream or lotion over makeup is not always realistic.

A few sweeps of this lets you refresh SPF, mattify and tidy up your complexion in one go, which is especially useful between sightseeing, lunch and whatever comes next.

Tip: Use it as a top-up over your regular sunscreen, rather than relying on powder alone for your initial morning protection.

Available at selected Watsons, Welcia, FairPrice, Unity and Don Don Donki stores, Watsons online,  Shopee and Lazada.
