ZD net has an interesting story about a Japanese software maker who’s launching a skin care guide for use on Nintendo’s DS portable game player. This unique software provides beauty tips based on the users’ body temperature and hormone balance.

We quote from the article:

Konami, known for sports titles such as Pro Evolution Soccer, said that by marking a target date such as a wedding in the software, DS users can get customized, daily skin care instructions in the run-up to the big day.

“We have developed the software under the concept of getting pretty while having fun,” Konami’s digital entertainment corporate officer, Naoyuki Notsu, told a news conference.

Konami Digital Entertainment is Konami’s game software unit.

The DS has two screens, opens like a book and allows gamers to control play with a stylus, instead of by manipulating a keypad.

Its intuitive playing style, coupled with software designed to cater to game novices, such as the Nintendogs pet-training game, has helped Nintendo expand its clientele beyond a young male audience to include women and the elderly.

The skin care software will go on sale on October 18 in Japan for $37 (4,500 yen). Konami has no specific plans at the moment for an overseas launch.

Now I just have to decide: do I want a new DS or an iPhone?
