Sientra Inc. is selling about $75 million of its common stock in a public follow-on offering.

The Santa Barbara, Calif.-based company also plans to grant the underwriters a 30-day option to buy up to about $11.3 million of additional shares.

Sientra, which sells medical aesthetics products to plastic surgeons, plans to use the net proceeds to implement sales and marketing initiatives, expand its U.S. and global commercial organizations, finance research and development efforts and to fund general corporate purposes. The company may also use part of the proceeds to acquire or invest in complementary businesses.

Stifel, William Blair and SVB Leerink are acting as joint book-running managers for the offer.
