Having Face Wash Sent to Japan

I was thinking of buying some skin care products from ebay, but ebay tells me this when I try to buy it:

"Certain quantity restrictions and/or licensure requirements may apply to the importation of cosmetics into your country.
Please check applicable regulations for specific import restrictions in your country.
They're for personal use and not for a business or redistribution (about 4-5 different bottles in a set)."

Does anybody know whether I am able to have these sent to Japan?

Similarly, are there some kind of laws regarding importing cologne or hair wax (just a bottle or two for personal use)? Because ebay shows the same message when I try to buy those.
Thanks!!

For reference...
I want melatonin to sleep, but I can only buy one little bottle of foreign reasonable one every time.

By Japanese Pharmaceutical Affairs Law called "Yakuji-hou" in Japan,
many ingredients of drugs, pills and so on
are restricted to import.
In this case, you can get from abroad a small quantity only for using up within a month.
If not so, it will be confiscated at customs house.

You can import cosmetics up to 24 pcs/item for 'personal use'.

Information for those who are bringing medicines for personal use into Japan
(Though the title says 'bringing' but it applies to personal import as well.)

Thanks for the replies!
Seems like it should be fine to have them sent here then :)
