Dannii Minogue thinks make-up is a ''time constraint''.

The 42-year-old singer, who has three-year-old son Ethan, admits she rarely wears any cosmetic products on her face any more because it takes too long to perfect.

Speaking to Australia's WHO magazine, she said: ''When I'm not working, I wear minimal makeup - when you're a mum it becomes a time constraint.

''Since I've had Ethan, I'm much more aware of what I'm putting in and on my body.''

The brunette beauty insists the days she ''used to sunbake with baby oil'' are long gone and she maintains her youthful glow with the occasional laser treatments.

However, she's adamant she'd never resort to extreme measure to help with the process of ageing, although she admits she has done in the past.

She explained: ''I don't use Botox. It was definitely something I did in a particular time of my life, but not anymore.''
