FEEDBACK

摘要

Sharing Feedback's puzzlement over La Prairie face cream and its claim to contain "magnetically charged particles of platinum" (23 June), Ash Choudry wrote to the company owning up to "struggling a little to understand how the particles can have a magnetic charge". He further confessed that "I don't understand what the 'electrical balance' of the skin is. Can you point me towards some kind of online medical resource that explains this?"
