incognito Insect Repellent Lotion contains naturally-derived PMD – the same active ingredient as their signature incognito spray and roll-on formulations. Apart from DEET, PMD is the only other active ingredient approved by Public Health England, the Centre for Disease Control (CDC), and the NHS as suitable for all destinations worldwide, including regions where mosquito-borne diseases are present, such as dengue, malaria and zika.
