Actress Gwyneth Paltrow has thanked water and its "healing power" by sharing her no make-up selfie on Twitter.

The 41-year-old posted a selfie sans make-up on the microblogging site to celebrate World Water Day on March 22, reports huffingtonpost.com.

Paltrow had also said that her beauty routine is "very minimal".

"After I drop my kids, I always exercise and then I take a shower and I basically just put on moisturiser - and that's kind of it," she said.

"If I have a meeting or something I'll put on some mascara, but that's as far as I go," she added.
