Mackenzie Phillips has dropped $50,000 on Botox, Restylane and laser treatments to her face, as well as 36 hours' worth of extensive dental work and hair extensions.
On ABC's Good Morning America Wednesday, Phillips, 50, said that she wants her makeover to reflect her desire to reinvent her life from the inside out.
"I've no desire to erase anything," she said. "I'm really happy."
The former child star - who has long battled substance-abuse problems - made headlines last year when she admitted her father, Mamas and the Papas musician John Phillips, raped her when she was 18.
She previously said the relationship became consensual, but on GMA she changed her tune. "I've learned from thousands of survivors across several continents … that there is no such thing as consensual incest, because of the inherent power," she explained.
"I do not believe he had malicious intent," she added of her father, who died in 2001. "I believe he was a man who was ravaged by drugs and alcohol."
Though some of her family members criticized her for talking to the press, Phillips -- who is now estranged from most of her family -- said she has no regrets about coming clean about her abusive past.
"OK, right now a child is being raped, so what should I do? Follow the path of sweep it under the carpet, don't talk about it?" she said on GMA. "The more you challenge the conspiracy of silence, the less silence will be acceptable."
