From Japanese Drugstore Shelves to the Dinner Table, They Turned a 2H2D Chat into a Checklist

The weekend Ajie got back from Kansai, he spread his suitcase open on the living room floor. Besides a few boxes of souvenirs, it was stuffed with three or four boxes of health products he'd grabbed on a whim at a drugstore. He'd only been curious at first—the same shelf had rows of labels packed with tiny print, packaging in colors brighter than the next, some saying "long-lasting," some saying "moisturizing," with prices ranging from a few hundred yen to over a thousand. He stood there looking for over ten minutes and in the end only picked one box. But after returning to Taiwan, the more he thought about it, the more something felt off: what exactly had he bought, and how was it different from everything else on that shelf?

When Ajie's girlfriend Xiaoqing got home from work, she saw the box sitting on the dining table with a handwritten note he'd scribbled beside it. She didn't immediately ask "why did you buy this?" Instead, she first asked what those few lines on the note meant. Ajie said he couldn't understand anything in the store, so he'd just copied down a few words from the packaging to look up later at the hotel. Xiaoqing laughed a little and said that was so like him on a business trip—writing everything down first and figuring it out later. So the two of them sat down, flipped the box over, and went through the label line by line.

Xiaoqing's attitude put Ajie at ease. He'd been a bit worried about being teased—after all, these kinds of products are often discussed jokingly in Taiwan, as if merely mentioning them means "there's a problem." But Xiaoqing just said that when you buy something, of course you want to understand it—especially what's written on the packaging, who it's for, and whether there are any precautions. None of that has anything to do with saving face. She also reminded him that many products on the shelf look similar but may actually fall into completely different categories. Some are general goods, while others may involve regulations for pharmaceuticals or medical devices. You can't decide based on a few big words on the package.

Ajie said that was exactly what confused him most in the Japanese store. Even though they were all in the same section, some said "quasi-drug," some said "cosmetics," and some said nothing at all, only emphasizing how it felt to use. He'd asked a store clerk at the time, and the clerk politely explained a bit, but his Japanese wasn't good enough and he only caught half of it. After returning to Taiwan, he wanted to understand it properly, so he started researching and typed "Japan 2H2D" into the search bar to see how these kinds of products are actually distinguished in terms of labeling and classification. Xiaoqing didn't stop him—she just said it was fine to look things up, but to check the sources carefully and not treat a single forum comment as a conclusion.

They eventually worked out their own comparison method. First, look at the official classification wording on the packaging, not just the advertising copy. Second, check whether the ingredients and precautions are clearly stated—especially warnings like "do not apply to these areas." Third, confirm whether you're currently taking any medications or supplements, because some things may require caution when used together. Xiaoqing said a coworker at her company had taken several kinds of supplements at once, then felt unwell and was reminded at the clinic to bring the list for a professional to review. That made Ajie realize that no matter what you buy, listing what you're already using matters more than rushing to compare which box works better.

Ajie also noticed that a lot of online discussion lumps different products together—someone takes their experience with A and applies it to B, or writes "how it felt" directly as "what it does." After discussing it, he and Xiaoqing decided that whenever they saw claims like that, they'd set them aside and go back to the packaging and official information. Xiaoqing also raised a question: if you can't even clearly say what category you bought, how can you compare it with anything else? Ajie nodded and said that at least now he knew the point of comparison wasn't whose product was stronger, but whose labeling was understandable, whose source could be verified, and whose usage conditions were clearly stated.

The following week, Ajie put the box in a drawer and didn't rush to use it. He messaged his cousin who works at a pharmacy. She said that if there were any concerns about this kind of product, the simplest approach was to bring the packaging along with a list of the medications or supplements you normally take, and ask a pharmacist or doctor to confirm whether there was anything to avoid. She also reminded him not to interpret a word on the packaging as a therapeutic effect on his own—often it's just marketing language. Ajie screenshotted that message and sent it to Xiaoqing. She replied: "That's exactly right. Ask first, then decide whether to use it."

That night they didn't circle back to the product itself, but talked about what "being ready" meant to each of them. Ajie said he used to think you just bought these things and figured it out later, but now he felt more at ease understanding first and buying after. Xiaoqing said she didn't care what he bought—she cared whether he was willing to voice his questions. The two of them later rewrote the note, dividing it into three columns: "Confirmed," "To Be Confirmed," and "Ask Someone." They stuck it on the fridge. Ajie laughed and said this was probably the first time he'd ever organized something from a drugstore into a checklist like this. Xiaoqing replied that the checklist wasn't to control him—it was so he wouldn't have to guess alone.
