The former Spice Girl said in an interview for the latest issue of British InStyle magazine that her and the footballer are not worried about getting older.
She said: 'I have no problem with surgery at all but for me, it looks ridiculous when you have a face that looks 25 and a body that looks 65. I think it's much more modern to go for a natural look.
'But ask me next year and that might change.'
David, 35, and Victoria admitted to using alternative therapies.
The 36-year-old said: 'We both like crystals, as in crystal energy.'
Victoria also praised the oxygen facials she gets from a dermatologist.
She added: 'Dr Lancer has really sorted my skin out.'
Although Posh says she definitely doesn't use fake tan.
Beckham said: 'I've embraced whiteness. I don't use any tanning products. Sometimes in photographs I look orange, which is really random, because I don't use fake tan at all.'
