Could seaweed-based face ash be the cure for acne?

Brown seaweed may not look like the answer to a spotty teenager’s problems, but scientists say it can banish the bugs that trigger acne.
An active ingredient from brown seaweed found only off the coast of Brittany, France, can cut spots by nearly two thirds. A new clinical trial of treatments containing the ingredient showed the number of spots fell by 64 per cent and blackheads by 60 per cent after just eight weeks.
The trial is the first cosmetics clinical study in acne to be published in an official dermatology journal.The study investigated products from a range of OXY treatments using the active compound called Phycosaccharide ACP.
They are mainly aimed at teenage boys and young men, with nine out of 10 suffering problem skin triggered by the male hormone testosterone.
