Can the technology prevent yellow armpit stains?Updated 4 months ago

Yellow stains are caused by deodorant/antiperspirant or the acidity of your sweat. The primary active ingredient in antiperspirants and deodorants is aluminium. Yellow armpit stains are caused when odourless, colourless sweat (which is a protein) reacts with the aluminium in a care product. We therefore recommend choosing a deodorant without aluminium. LABFRESH technology cannot repel these yellow stains.
