(Corrects Allergan company stock price in final paragraph)

NEW YORK, Sept 14 (Reuters) - Allergan Plc said revenue from its medical aesthetics business could double by 2025, even as it faces increasing competition for its blockbuster wrinkle treatment, Botox.
The drugmaker announced earlier on Friday the acquisition of Bonti Inc, which makes a shorter-acting neurotoxin than Botox.
Allergan is also doubling its investment in direct-to-consumer ad spending and beefing up its sales force as companies like Revance Therapeutics Inc and Evolus Inc vie to wrest market share with rival treatments to Botox. The company made the announcements at its Medical Aesthetics Day in New York.
Chief Commercial Officer Bill Meury said Allergan expects revenue at its medical aesthetics unit to grow to $7 billion to $8 billion. That compares with revenue of $3.8 billion from the business in 2017.
Beyond Botox, the unit includes dermal filler Juvederm, the CoolSculpting fat-freezing systems, and other treatments.
He said the forecast implied an 8 to 10 percent compound annual growth rate.
Meury said the Bonti acquisition would allow the company to market a new "starter toxin." Patients could test drive the treatment, which lasts for two to four weeks, to help them decide if they want to use longer-term Botox.
Shares of Allergan fell 0.9 percent to $188.21 on Friday, while shares of Revance were down 1.1 percent and Evolus fell around 2.5 percent. (Reporting by Michael Erman Editing by Chizu Nomiyama and Bernadette Baum)
