A & F PEARS LTD.
Pears soap is the natural way to a lovely complexion, because it is made from simple, purr ingredients – glycerine, natural oils, cedar, thyme. And then it is mellowed and aged for three month until it reaches a pure transparent. This unique aging process also makes Pears soap extremely long lasting.
Pears soap is specially made to take care of the most delicate of fine skins, cleansing thoroughly, gently naturally. Because the formulation includes glycerine, Pears soap is very effective on dry skin and gentle enough for a baby's skin.
Made in England in the traditional way since 1789.
