Mulethi is more commonly known as licorice; and is the root of Glycyrrhiza glabra. It is extremely popular because of its anti-inflammatory and anti-oxidant properties; the latter of which is attributed to the presence of galbrene in it. Scavenging harmful free radicals of the skin, galbrene, together with the sunscreen properties of licorice, control skin-aging. Licorice also contains a molecule named licochalcone, which works wonders for acne-prone skin; by controlling sebum/oil production and killing bacteria. Another active ingredient in licorice is galbridin. It is a mild and non-toxic bleaching agent; and thus helps in skin lighting and brightening, as well as fighting hyper-pigmentation; without the risk of permanent discoloration.
