The bottom line

This week I’ve been testing Waitrose own-label Baby Bottom Butter.

Designed to prevent nappy rash, sales shot through the roof last year when the news spread about the softening effect it was having on mother’s skin after they used it on their own faces.

Indeed, Bottom Butter (£2.40 for a 200ml jar; ingredients olive oil, vanilla and chamomile oil) does seem to have a very similar effect on my face to Eve Lom’s far more expensive cleanser (£76.34 for a 200ml jar; main ingredients cocoa butter, chamomile oil, clove oil and eucalyptus oil).

I'm going to stick with the Waitrose version for now - as far as I can tell, the Eve Lom version costs an extra £73.94 just because it includes clove and eucalyptus oil (known for their antiseptic qualities) and comes with a muslin cloth...
