A good daily sunscreen costs S$15 to S$47 in Singapore, and this week Watsons and Guardian have cut almost every bestseller. We priced eight on 5 October 2026, from a S$15.22 Biore gel to a Buy 1 Get 1 on Beauty of Joseon.
Singapore's UV index sits in the "extreme" band on most clear afternoons, so sunscreen is a daily buy here, not a holiday one.
> Quick view: cheapest good pick is Biore UV Aqua Rich Watery Gel at S$15.22 (Watsons, to 14 Oct); most bestsellers run S$20-S$47; the catch is that Watsons' deals end 14 Oct and Guardian's 27 Oct, so the same tube can cost 25% more next month.
WHY IT WINS: Kao's Biore UV Aqua Rich line is the Japanese drugstore staple for a reason. The Watery Gel and Watery Essence are both SPF50+ PA++++, spread like water, dry without a white cast and work on face and body, so one tube covers a whole morning routine.THE PRICE: on 5 October Watsons sells the Watery Gel 70ml at S$15.22 (was S$20.30, 25% off), the cheapest SPF50+ on this list, and the Airy Hold Cream 70g at S$19.92 (20% off). Both markdowns run to 14 October 2026. Guardian has the Watery Essence 70g at its regular S$20.30.FINE PRINT: the Watery Gel feels slightly tacky for the first minute on oily skin; if you hate that, the Airy Hold Cream sets matte.BEST FOR: anyone who wants a cheap, pleasant daily sunscreen for face, neck and arms.
Watsons: UV Aqua Rich Watery Gel 70ml S$15.22 (was S$20.30, 25% off) and Airy Hold Cream 70g S$19.92 (20% off), 5-14 Oct 2026.

WHY IT WINS: the Korean cult sunscreen that turned rice and probiotics into a TikTok staple. Relief Sun (Rice + Probiotics) SPF50+ PA++++ is a light, moisturising cream with a dewy finish that sits well under makeup and suits normal to dry skin. Oily or combination skin should pick the Relief Sun Aqua-Fresh (Rice + B5) version instead.THE DEAL: Watsons lists both at S$28.95 for 50ml, and the original Relief Sun is on Buy 1 Get 1 from 5 to 14 October 2026: add two to the cart and one is free, which makes it about S$14.48 a tube. It is out of stock online at Guardian.FINE PRINT: the free unit only applies when two are in the same cart, and the B1G1 label we checked sits on the original Relief Sun, not the Aqua-Fresh.BEST FOR: dry or normal skin, and anyone who wants a two-month supply for the price of one.
Watsons: Relief Sun (Rice + Probiotics) SPF50+ 50ml S$28.95, Buy 1 Get 1 (add 2 to cart), 5-14 Oct 2026.

WHY IT WINS: the dermatologist favourite. The UVMune 400 range adds Mexoryl 400, a filter La Roche-Posay says blocks ultra-long UVA rays that most sunscreens miss, in a fragrance-free formula made for sensitive and photosensitive skin. Pick the Invisible Fluid for normal skin, Oil Control Fluid or Gel Cream for oily skin, or the Anti-Dark Spots fluid for pigmentation.THE PRICE: Guardian sells the Fluid, Oil Control Fluid, Oil Control Gel Cream, Hydrating Cream and Tinted Fluid at S$45.50 each (was S$56.90) from 30 September to 27 October 2026, and spending S$80 on La Roche-Posay there adds a free Hyalu B5 Serum 10ml while stocks last. Watsons lists them at the full S$56.90 but takes 33% off when you buy three, to 7 October.CHEAPER ROUTE: the kids' Dermo-Pediatrics Invisible Fluid 50ml is S$27.10 at Guardian with the same SPF50+ rating.BEST FOR: sensitive, acne-prone or pigmentation-prone skin, and anyone on retinoids or after laser or IPL.

WHY IT WINS: a Korean bestseller that feels like a moisturiser. The Birch Juice Moisturising Sunscreen SPF50+ uses birch sap and hyaluronic acid for hydration, plus niacinamide and adenosine, and Watsons' listing says it is dermatologically tested and hypoallergenic. It leaves no white cast and works as a one-step moisturiser and sunscreen on normal skin.THE PRICE: Watsons sells the 50ml at S$19.20 (was S$32, 40% off) under its Best Buy tag from 5 to 14 October 2026. That is half Guardian's S$38 list price, and Guardian is out of stock online anyway.FINE PRINT: it is a dewy chemical sunscreen, so very oily skin may find it too rich by mid-afternoon.BEST FOR: dry or dehydrated skin, and anyone who wants to skip the separate moisturiser.
Watsons: Birch Juice Moisturising Sunscreen 50ml S$19.20 (was S$32, 40% off), 5-14 Oct 2026.

WHY IT WINS: Japan's best-known sport sunscreen, from Shiseido. The Perfect UV Sunscreen Skincare Milk SPF50+ PA++++ uses what Anessa calls Auto Booster technology, which it says strengthens the UV film on contact with sweat, water and humidity. That makes it the one to pack for Sentosa, a run along East Coast or a long outdoor day.THE DEAL: Watsons sells the 60ml gold bottle at S$47 and takes 30% off when you buy two, from 5 to 14 October 2026 (about S$32.90 a bottle). Guardian has the gentler Mild Milk 60ml at S$37.60 (was S$47) and the Brightening UV Gel 90g at S$28.80 to 27 October; its Skincare Milk was out of stock online on 5 October.FINE PRINT: it is a milk you shake before use, and the water-resistant film needs a proper cleanser or oil to remove at night.BEST FOR: outdoor sport, beach days and anyone who sweats through ordinary sunscreen.

WHY IT WINS: a French pharmacy fluid with a dry-touch matte finish. Photoderm Aquafluide SPF50+ PA++++ is fragrance-free and water- and sweat-resistant, made for sensitive skin, and its thin texture dries fast enough to put foundation on top a minute later.THE PRICE: Guardian sells the 40ml at S$32.90 (was S$43.90) from 30 September to 27 October 2026. In the same Guardian sale, the Photoderm XDefense and Spot-Age fluids are S$35.10 and the Lait Ultra face-and-body milk is S$39.60.FINE PRINT: 40ml is a small bottle, so at a proper two-finger dose for the face it lasts about six weeks.BEST FOR: oily or combination skin, office makeup wearers and anyone who hates a shiny finish.
Guardian: Photoderm Aquafluide SPF50+ 40ml S$32.90 (was S$43.90); XDefense and Spot-Age S$35.10, 30 Sep-27 Oct 2026.

WHY IT WINS: a pink-tinted physical (mineral) sunscreen that brightens dull or sallow skin, so many people wear it instead of a light base. The Tone Up Physical Sunscreen SPF50+ PA++++ is labelled for sensitive skin, with a 6-free formula, ceramide and botanical extracts, and the box calls it ultra-light and moisturising.THE PRICE: Guardian sells the 50ml at S$24.70 (was S$30.90) from 30 September to 27 October 2026, and the non-tinted Physical Sunscreen at S$23.90. Watsons lists the Physical Sunscreen at the full S$30.90, and the older chemical Tone Up UV Essence at S$30.20.FINE PRINT: the tone-up tint suits fair to medium skin; on deeper skin tones it can look ashy.BEST FOR: sensitive skin that reacts to chemical filters, and a no-makeup brightening look.

WHY IT WINS: a hydrating fluid from the brand behind the long-running Ultra Sheer range. Hydro Boost Hydrating Fluid SPF50 combines hyaluronic acid, pro-vitamin B5, niacinamide and antioxidants, and Neutrogena's artwork says it suits all skin types with no white cast. It is thinner than Round Lab's cream, so it layers more easily under makeup.THE PRICE: Guardian sells the 50ml at S$25.40 (was S$33.90) from 30 September to 27 October 2026; Watsons charges the full S$33.90. For the body, Guardian has Beach Defence Lotion SPF50 198ml at S$23.15 (was S$30.90).FINE PRINT: SPF50 is a single plus short of the SPF50+ rating most rivals here carry, which matters little in daily use if you apply enough.BEST FOR: dry or dehydrated skin that wants a fluid, not a cream.
Guardian: Hydro Boost Hydrating Fluid SPF50 50ml S$25.40 (was S$33.90); Beach Defence Lotion SPF50 198ml S$23.15, 30 Sep-27 Oct 2026.

For most people, Biore UV Aqua Rich Watery Gel SPF50+: light, no white cast, face and body, and S$15.22 at Watsons to 14 October 2026. For sensitive skin, La Roche-Posay Anthelios UVMune 400 at S$45.50 at Guardian (to 27 October) is the dermatologist pick.
A matte fluid. Bioderma Photoderm Aquafluide (S$32.90 at Guardian) dries to a dry-touch finish and is water- and sweat-resistant; La Roche-Posay's UVMune 400 Oil Control Fluid (S$45.50 at Guardian) is the pick if your oily skin is also sensitive. Biore's Airy Hold Cream (S$19.92 at Watsons) is the budget option.
At Watsons this week. Relief Sun (Rice + Probiotics) SPF50+ 50ml is S$28.95 on Buy 1 Get 1 from 5 to 14 October 2026, so two tubes cost S$28.95, about S$14.48 each. Guardian lists it at the same S$28.95 but was out of stock online on 5 October.
Singapore's UV index regularly reaches the extreme range around midday, so an SPF50 or SPF50+ broad-spectrum sunscreen is the sensible daily choice. Apply about two finger-lengths to face and neck, and reapply every two hours outdoors or after swimming, sweating or towelling.
