Japanese skincare and cosmetics have a loyal following abroad, and for good reason. Whether it is a gentle cleansing oil, a well-loved sunscreen, or a discontinued shade someone has been hunting for years, a lot of it never officially reaches overseas shelves. If you are already in Japan and shopping on behalf of a friend or reader, here is how to buy well and ship without nasty surprises.
What people actually want
The steady requests tend to be sunscreens (the light, high-SPF kind), cleansing oils and balms, sheet masks, hydrating lotions (the watery "toner" step Japanese routines love), and a handful of drugstore staples that cost a fraction of their export price. Prestige counter brands get asked for too, but the drugstore tier is where the real value sits.
Where to buy
Rakuten is the workhorse. Official brand stores and large drugstore chains both run shops there, so you can compare sellers, read reviews, and often stack points. Stick to the official brand store or a well-rated pharmacy seller rather than the cheapest unknown listing.
Physical drugstores (Matsukiyo, Welcia, Sundrug and friends) are great when you want to check a product in person and grab the freshest stock. For anything discontinued or limited-edition, Mercari is the place people turn to, since sellers clear out old shades and packaging there.
Reading a listing like a local
Watch for 内容量 (volume or net weight), 使用期限 (use-by, if listed), and whether it is 新品 (new) or 未使用 (unused). On Mercari, "未開封" means unopened. Photos matter: ask for a shot of the base of the tube or box, where you will often find the 製造番号 (lot or manufacture number). That number, plus the batch, lets a buyer roughly date the product.
Expiry, lot and authenticity
Japanese cosmetics are not always stamped with a printed expiry, because the law only requires one when a product lasts under three years unopened. Unopened staples are generally fine for around three years, but freshness still matters for sunscreens and anything with active ingredients. For authenticity, buying from official brand stores or established drugstore sellers is the simplest protection. If a counter brand price looks too good on a marketplace, treat it with suspicion and cross-check the packaging against the brand's official images.
Shipping and import limits
This is where cosmetics get fiddly. Liquids, gels, pressurised aerosols (hairsprays, some sunscreens, mousses) and items with certain flammable or alcohol content face air-shipping restrictions. A proxy service may simply refuse to forward aerosols or large liquid volumes, or route them by slower surface mail. Always confirm before you buy a case of anything.
On top of courier rules, some destination countries cap how much cosmetic product an individual can import for personal use, either by quantity or by item count per shipment. A friend receiving a dozen of one lipstick may be treated very differently from someone receiving two. It is worth checking the destination's personal-import guidance first so a parcel is not held or returned.
Some countries limit personal cosmetic imports by quantity or item count, and couriers may restrict or refuse liquids and aerosols. Check both the destination's rules and your proxy's prohibited-items list before ordering.
Customs and cost
For a small, light parcel of skincare the customs charge is often minor or nil, but that depends entirely on the destination's threshold and how the value is declared. Duty and tax are usually calculated on the item value plus shipping, so a heavy box of glass bottles can tip over a threshold faster than you expect. Our landed cost calculator gives you a quick estimate before you commit, and if you are sending to Australia the Australia customs guide walks through the current rules.
Put simply: buy from reputable sellers, check the lot number and freshness, avoid aerosols unless your proxy allows them, and confirm the destination's personal-import limits. If you want sellers who already handle overseas forwarding, our list of Rakuten shops that ship abroad is a good starting point.
