"I think getting panicked about aging is not worth it -- I was 60 last year, and it's all part of life. I really think you have to embrace all the different ages," Twiggy tells StyleList.
"I'm very lucky because I'm healthy -- if you're healthy, you've got everything -- and I've got a lovely husband and gorgeous kids."
With such a full life, she doesn't need Botox to keep her young. "I've got friends that have had stuff done and their faces don't move -- especially in L.A. They look like frozen people," she says.
"I'm not going to do Botox. It's poison." She also doesn't understand pumping up your lips. "They look like somebody's punched them," says Twiggy.
That's not to say she's ruling out other procedures. "I have friends that have had things done, and they look like they've been on vacation," she says, adding, "I'm not saying I'm not going to do something. But if you're going to do it, [do] research and get the best people."
For now, Twiggy will stick with her tried-and-true maintenance methods. "I use a heavy, thick English cream, and I have for years. I always take my makeup off -- going to bed with your makeup on is not a good idea.
"I splash myself with water in the morning to wake myself up. I get bags under my eyes when I wake up, so I pop a packet of frozen peas on for 10 minutes, or cold tea bags."
Twiggy was in New York City to preview her new HSN sportswear collection, Twiggy London, which consists of pieces inspired by the greatest hits from Twiggy's own closet.
"We wanted to kick off with what I love," she says. "We did a gypsy skirt because I love gypsy skirts. I wanted to do satin sneakers with velvet laces. The Union Jack bags [see above] are because I love tote bags. The waistcoat [vest] is a version of an old vintage one I have from the 1930s.
"It's come out so beautifully," she says of her line. "I'm thrilled."
The Twiggy London collection, which ranges from $29 to $99, debuts April 3 on HSN and hsn.com.
