I started using topiclear but then I didn't really see any difference and I heard that it was steroid based. Any suggestions?

Try nivea's underarm lightening roll on deodorant with liquorice extracts. It's worked for me!! :)

Underarm odour is caused primarily by resident bacteria, no matter what you ate. Most (non-aluminum) mineral salts will create a hostile environment where the critters cannot thrive. For the past quarter-century or so, I’ve used nothing but plain old baking soda–the same stuff I used in cooking and cleaning. Cheap, multi-purpose, and works a treat! If you are looking for some natural products then use Natural Deodorant
