Avon Skin So Soft – still going strong after more than 20 years. Originally marketed as a skin softener, women found it to be a standout product in terms of its effectiveness even healing cracked skin and preventing stretch marks. Marketed exclusively through Avon’s army of personal sales representatives and through home parties, the company already had a big hit on its hands when it was accidentally discovered that Skin So Soft has attributes of a Bug Repellent. The market for this product has grown exponentially into a diverse and large demographic, which includes use in the military, with gardeners, construction workers, athletes and sports fans, and for use on pets and horses. Skin So Soft, which sells for $10 and under, has sold multi-millions of units and has also been found to be useful in 100 different ways from grease and gum removal to cleaning and softening leather.
