January Jones is ''afraid'' of having plastic surgery.

The 'Mad Men' actress isn't against people going under the knife to enhance their looks, and she might even have it done in the future, but she admits she couldn't do it right now because she's scared.

She told online magazine Violet Grey: ''Whatever helps a person feel beautiful and confident is fine with me.

''I personally am afraid of the procedures that involve anaesthetic but ask me again in twenty years.''

However, the 36-year-old star has found another way to keep herself looking younger, and it's a little tip she picked up from her mother, by not over plucking her eyebrows because it structures the face.

When asked what she's learnt from her mother over the years, she explained: ''She [my mother] always told me that if I kept making so many weird and ugly faces my face would eventually freeze that way. Luckily I found a job where funny and/or frozen faces are encouraged.

''Also, to not over pluck your eyebrows, a strong brow makes you look younger.''
