Regulatory Support


MSL fully understands the role of the Responsible Person within Cosmetic Regulation 1223/2009 and can either adopt that position for a brand or manufacturer or alternatively advise clients on the actions necessary if they wish to act as RP for their own products (if possible).

MSL is therefore able to offer a dual Responsible Person service, helping companies gain regulatory compliance and seamless entry to both the EU and UK markets without having to deal with multiple service providers.
