The market for home light-based (IPL) hair-removal devices has grown in Japan, and they are popular purchases for visitors too. But the expectation — "same results as a salon", "permanent hair removal" — does not match how these devices are actually classified, and the Consumer Affairs Agency has issued warnings.
| Class | Who | How it works | What it can do | Legal status |
|---|---|---|---|---|
| Medical laser hair removal | Doctors and nurses (medical institution) | High-output laser destroys the follicle | Permanent hair removal (suppresses regrowth long-term) | Medical procedure (MHLW notice, 2001) |
| Salon light hair removal | Beauticians | Lower-output light (IPL etc.) | Hair reduction (not permanent) | Illegal if it destroys the follicle. The words "permanent hair removal" may not be used |
| Home light device | You | Light at still lower output | Hair removal and reduction | General goods (雑貨, zakka — neither a medical device nor a quasi-drug) |
[Verify] Check the scope of medical procedures against the MHLW notice (Iseii-hatsu No. 105, 2001), and the incident cases against the published materials of the Consumer Affairs Agency and the National Consumer Affairs Center of Japan.
It does not. Permanent hair removal is for medical lasers only. Home devices reduce hair, and the assumption is that hair returns once you stop.
That is the main cause of burns, blisters and pigmentation. Follow the manual's output setting (graded by skin tone) and the interval between sessions (for most devices, once every 2 weeks).
The light reacts to melanin, so tanned skin carries a high burn risk, and products forbid it. In summer, sunscreen and shade are a precondition for use.
Each product has its own forbidden areas. Around the eyebrows, near the eyes, mucous membranes, moles and tattoos are forbidden by most products. Follow the manual.
Salon light hair removal is hair reduction, and may not be described as permanent. Understand the difference from a medical institution, and check the contract and cancellation terms (the cooling-off right under the Act on Specified Commercial Transactions). For problems, call the consumer hotline on 188 (Japanese-language line to your local consumer affairs centre).
