Q: Can I use deodorants if I have psoriasis under my armpits?

A: Deodorants can sometimes aggravate psoriasis in the armpits or trigger a flare-up. This is because of the chemicals in them that can irritate the skin. There are deodorants designed for sensitive skin (sometimes referred to as hypoallergenic) and they contain less of the chemicals that can cause irritation and they may also contain emollients to help moisturise your skin.
