Japanese skincare, read before it reaches your shelf.
Japan regulates skincare in three categories, not two. The middle one approves actives at fixed concentrations, with decades of post-market data, and almost none of that paperwork exists in English. I read those files for aesthetic clinics in the United States.

The gap
Your patients bring Japanese products in from their suitcase. The only information on them is the brand's marketing.
After lasers, peels and microneedling, most US practices stock a French barrier line. Japan has pharma-made sensitive-skin lines that are sold through dermatology clinics there, built for exactly that moment, and no door into a US practice. The evidence exists. It is in Japanese, in a category most US clinicians have never heard of.
The file
Is it a quasi-drug (医薬部外品) or a cosmetic? If it is a quasi-drug there is a named active, an approved concentration and a claim with a dossier behind it. I read the dossier.
The gate
A Japanese cosmetic can be a US prescription drug (azelaic acid at 20%). Japanese sunscreens cannot be sold as sunscreen in the US. Anything that is a drug in Japan never crosses as skincare. I tell you before a patient does.
The wording
What your menu and your retail shelf can say about a Japanese line in your state, in the words a reviewer would let stand. No "healing", no "repair", no borrowed Japanese claim.
Four questions to ask about any Japanese line
- Quasi-drug or cosmetic, and which active at what concentration?The category is printed on the box. The concentration is in the file, not on the box.
- Who is the US responsible person and the importer of record?If nobody can answer this, the product is a suitcase product, not a shelf product.
- What does the Japanese evidence actually show, and in which model?A cell result is a cell result. A quasi-drug approval is a regulator's read of a human dossier. They are not the same sentence.
- What wording survives a US review?The Japanese claim is approved in Japan. Your menu needs its own.
From a client

The Japan Shortlist
For your menu: post-laser barrier care, pigmentation, or sensitive skin. Three Japanese products, the evidence behind each, the claim wording that is safe on a US menu, and an introduction to the brand or its importer. Delivered as one document you can hand to your aesthetics manager.
From US$1,500 per shortlist. Placement is handled with the brand, never with you.
Education and evidence reading, not legal or medical advice. I do not sell products, hold inventory, or act as an importer. US registration and labelling are done by the brand's importer; I read, I introduce, and I say what the file supports.
