The position, representing around 57 million shares, is held through Rock Nominees.\n\nThe accumulation comes during a turbulent period for the company. Shares in SkinBioTherapeutics plunged earlier this year following the suspension and subsequent resignation of former chief executive Stuart Ashman amid allegations of financial misrepresentation.\n\nThe identity of Mark H Dixon has not been officially confirmed, and the company has not commented on who ultimately stands behind the growing stake. One unverified report has suggested a possible link to a figure involved in horse race breeding, though this has not been substantiated.\n\n**TR-1: Standard form for notification of major holdings**\n\n|   |   |   |   |   |   |   |\n| --- | --- | --- | --- | --- | --- | --- |\n| NOTIFICATION OF MAJOR HOLDINGS (to be sent to the relevant issuer and to the FCA in Microsoft Word format if possible) i |  |  |  |  |  |  |\n|  |  |  |  |  |  |  |\n| 1a.
