Exhibit 99.4

ALLERGAN EXTENDS EXPIRATION DATE OF EXCHANGE OFFER FOR INAMED CORPORATION

IRVINE, Calif., December 16, 2005 — Allergan, Inc. (NYSE: AGN) today announced that it has extended the expiration date of its exchange offer for all outstanding shares of common stock of Inamed Corporation (NASDAQ: IMDC). The exchange offer will now expire at 5:00 p.m. Eastern Time on Monday, January 9, 2006. The exchange offer was previously scheduled to expire at 12:00 midnight, Eastern Time, on Tuesday, December 20, 2005. Approximately 1,147,000 shares, or 3.2% of Inamed’s outstanding common stock, were tendered as of the close of business today.

In the offer, Allergan will exchange for each outstanding share of common stock of Inamed, either $84 in cash or 0.8498 of a share of Allergan common stock, at the election of the holder. Elections of Inamed stockholders are subject to proration as described in Allergan’s Form S-4 initially filed with the Securities and Exchange Commission (SEC) on November 21, 2005, and subsequently amended, so that 45% of the aggregate Inamed shares tendered will be exchanged for cash and 55% of the aggregate Inamed shares tendered will be exchanged for shares of Allergan common stock.

Allergan also announced that it has received a request for additional information, referred to as a second request, from the Federal Trade Commission, pursuant to the Hart-Scott-Rodino Antitrust Improvements Act, in connection with the transaction. The second request extends the initial 30-day waiting period under the HSR Act that expired yesterday. Allergan has been working with the Federal Trade Commission staff concerning the divestiture of Reloxin^® and had anticipated the issuance of the second request as part of that process. Allergan does not expect the second request to result in a material delay in consummation of the transaction.

Relevant risks and uncertainties include those referenced in Allergan’s filings with the SEC (which can be obtained as described in “Additional Information” below), and include: general industry and pharmaceutical market conditions; general domestic and international economic conditions; technological advances and patents obtained by competitors; challenges inherent in product marketing such as the unpredictability of market acceptance for new pharmaceutical and biologic products and/or the acceptance of new indications for such products; uncertainties regarding analysts and other’s projections and estimates for revenues and earnings of Inamed and market growth rates; domestic and foreign health care reforms; the timing and uncertainty of research and development and regulatory processes; trends toward managed care and health care cost containment; and governmental laws and regulations affecting domestic and foreign operations.

These risks and uncertainties could cause actual results to differ materially from those expressed in or implied by the forward-looking statements, and therefore should be carefully considered.
