Cosmetic medical device company Tria Beauty Inc. has so far raised $40 million in an open-ended equity funding round, and 13 unnamed investors are contributing to the pot, according to regulatory documents.

The Pleasanton, Calif.-based company expects to wrap up the offering by 2015 with no cap on the total raised, according to company filings. Tria went public 1 year ago in an IPO underwritten by Morgan Stanley and Wells Fargo.

Tria Beauty makes at-home hair removal and skin rejuvenation devices that operate with light-emitting technology. The products are sold through via physician prescription as well as over the counter at retail stores.

Regulatory filings reveled that several company directors involved in the filing have links to Vivo Ventures, Aisling Capital, Technology Partners, DeNovo, SurgeRx, PLxPharma and Bay City Capital.

Last year Tria Beauty launched a hoped-for $20 million raise from 6 unnamed investors.
