Lotte, Binggrae and Haitai are converting familiar bars and cones into low-sugar lines. The catch is that “zero” describes one metric, while texture, calories and digestion still have to be engineered.
Open a Korean supermarket freezer in 2026 and the argument is no longer between virtue and ice cream. It is between two versions of the same childhood object. A World Cone can now sit beside World Cone Vanilla Low Sugar. A Pig Bar has a low-sugar relative. Jaws Bar, Screw Bar, Summer Crush, Tank Boy and Polapo have all been translated into the language of zero or reduced sugar. The names are familiar; the nutritional bargain is new.
This is the trend: low- and zero-sugar ice cream has moved out of a specialist diet corner and into the country’s mass-market brand architecture. Korea’s largest frozen-dessert groups are not asking shoppers to learn an earnest new label. They are retrofitting products that already carry decades of memory. That makes the shift larger than a collection of launches—and more complicated than the word zero suggests.
The freezer filled with doubles
The replication is visible across competitors. Lotte Wellfood began building its ZERO platform in 2023, then extended the proposition into Jaws Bar, Screw Bar, World Cone, Tico and Pig Bar. Binggrae first released zero-sugar versions of Summer Crush and Saenggyul Taenggyul in 2024, then launched Deep & Low as a dedicated low-sugar range in 2025. Haitai Ice Cream followed with zero versions of Tank Boy pear and Polapo Sport. By May 2026, Korean reporting described a category no longer led by test products but by reduced-sugar editions of megabrands.
The sales direction supports that reading, although the base is still small. MoneyToday reported that Binggrae’s zero- and low-sugar frozen-dessert revenue doubled in 2025 compared with 2024, while Haitai’s rose roughly eightfold. Lotte said World Cone Vanilla Low Sugar and Tico Milk Choco Low Sugar sold about two million units within 80 days of launch. These are company-supplied figures rather than an audited category total, but they show adoption across three portfolios, several formats and more than one retail season.
A US Department of Agriculture market brief had already identified zero-sugar ice cream as a growth pocket in Korea in 2024, driven by younger consumers and sensitivity to sugar. What changed afterward was not the desire to cut sugar. It was the industry’s confidence that the claim could be attached to mainstream pleasure without quarantining the product as diet food.
That change is clearest in Binggrae’s Deep & Low range. The company launched with chocolate and coffee crunch bars, then added chewy bars and soft pouch formats. Its own product page now presents seven variants and promises no compromise on flavour or texture. The point is variety, not abstinence. Even the celebrity advertising behaves like ordinary confectionery marketing: bright, playful and built around desire. The health message has been absorbed into the entertainment.
Sugar was doing more than making things sweet
The conflict sits inside the ice cream itself. Sugar contributes sweetness, but it also lowers the freezing point, controls hardness and helps create a scoopable or biteable texture. Remove it and the manufacturer must rebuild those functions with other ingredients. In Korea, that often means allulose, maltitol or other sugar alcohols and high-intensity sweeteners, combined with changes to solids, fat and stabilisers.
The result is not one coherent “zero” product. It is a shelf of different trade-offs. An April comparison by Asia Business Daily standardised 12 low-sugar ice creams from Lotte, Binggrae and Lalasweet to 100 millilitres. World Cone Vanilla Low Sugar contained 2.4 grams of sugar but 11.9 grams of sugar alcohols. Pig Bar Low Sugar cut 23.3 grams of sugar compared with the original, while carrying 17.1 grams of sugar alcohols. Binggrae’s zero-calorie tangerine ice used allulose to replace conventional sugar; its Deep & Low chocolate bar was lower in calories than Tico’s low-sugar equivalent, even though Tico was lower in sugar.
Those distinctions matter because “zero sugar,” “low sugar” and “zero calories” are not synonyms. Binggrae’s original Deep & Low launch materials listed 2.4 grams of sugar per bar, but also 153 calories for its chocolate crunch bar and 159 for coffee. A shopper can rationally choose that product to reduce sugar. The same shopper would be mistaken to read the front-of-pack idea as permission to treat every version as calorie-free.
There is a second limit. Korea’s food-safety rules require a warning on products containing sugar alcohols because excessive intake can cause diarrhoea. Tolerance varies, and the amount in one serving does not automatically make a product problematic. Still, a portfolio built on repeatable “guilt-free” pleasure has to respect the awkward fact that the substitute can become the constraint. The more brands stretch zero into cones, coated bars and creamy sandwiches, the more carefully they must communicate what was removed, what replaced it and what remains.
A health trend doing repair work
The non-obvious part of the boom is what it is repairing. Korea’s retail ice-cream market was worth 1.41 trillion won in 2025, according to data cited by Korea JoongAng Daily—nearly 30 percent below its 2015 value. A falling birth rate has reduced the traditional child audience, while iced coffee and bingsu compete for summer spending. In that setting, low sugar is not merely a nutritional response. It is a method for making mature assets newly relevant to adults.
Line extensions are especially useful in a stagnant freezer. The company keeps the recognised silhouette, flavour memory, manufacturing knowledge and distribution slot, while adding a reason for lapsed buyers to reconsider. It can renovate World Cone without persuading the retailer to bet on an unknown cone; it can turn Tank Boy into a current health conversation without discarding Tank Boy. The innovation is partly chemical, but the commercial mechanism is inheritance.
That helps explain why the category is spreading through classics rather than being dominated by one disruptive wellness brand. Specialist low-sugar maker Lalasweet helped prove that an audience existed. The large manufacturers can now distribute the premise across bars, cones, pouches and sandwiches, converting a niche benefit into a choice architecture: original or reduced sugar, familiar pleasure either way.
The freezer therefore reveals a broader product lesson. A mature category does not always need a new flavour to restart attention. Sometimes it needs to reissue its back catalogue under a changed consumer rule. In Korea, that rule is not “stop eating ice cream.” It is “make indulgence legible to the person who now reads the sugar line.”
The summer test can mislead
There is serious counter-evidence. The zero and low-sugar segment still accounts for a small share of total frozen-dessert sales. The 2026 market rebound also coincided with an early heat wave: Lotte’s June ice-cream sales rose about 10 percent year on year, while GS25’s jumped 31.3 percent. Hot weather can make almost every freezer strategy look clever for a month.
Nor is launch velocity the same as loyalty. The decisive evidence will be repeat purchase after promotions, performance outside peak summer and whether the variants keep their shelf slots once curiosity fades. If consumers decide the texture is inferior, if digestive warnings become a deterrent, or if “zero” creates confusion rather than trust, the products may remain optional shadows of the originals.
For food professionals, the useful test is brutally practical: compare the reformulation with the original blind; measure melt, bite and aftertaste; ask shoppers what they think “zero” means; then track second and third purchases, not sampling. A claim that wins the first sale but damages the second is not a platform.
The label must survive the spoon
Low-sugar ice-cream boom matters because it shows how a mature category can use a health rule to reactivate familiar brands. The strongest opportunity is not another worthy diet label; it is a recognisable bar, cone or sandwich whose sugar reduction survives a blind taste test. The risk is semantic overreach: shoppers may hear “zero” and infer no calories, no compromise or unlimited permission, while formulations vary sharply. Watch winter shelf space, repeat purchase and promotional dependence. Those measures will reveal whether reduced sugar has become a durable buying criterion or merely a warm-weather reason to sample an old favourite again.
Korea’s freezer is showing how a nutritional claim becomes mainstream: not by replacing pleasure, but by borrowing its most familiar forms. The opportunity is substantial for brands with ageing icons and strong distribution. Yet the winners will be the products that make the trade-off intelligible. Sugar reduction can be meaningful without pretending that calories, ingredients or portion size disappeared. If low-sugar editions retain their shelf space through winter and generate repeat purchase without heavier promotion, this will look like a durable rewrite of the category. If they retreat after one hot season, 2026 will have been less a health revolution than a very effective summer line-extension campaign.
