Underarm rash with salt stick deodorant

What to do with rash caused from natural salt stick deodorant?

[Bhupinder Kaur, MD]

Hello,
I cannot confirm anything without examination but it sounds like irritant contact dermatitis. Irritant dermatitis, the most common type of contact dermatitis, involves inflammation resulting from contact with acids, alkaline materials such as soaps and detergents, cosmetics, or other chemicals.

Avoid using any lotions and creams for the meantime. Wash the area with a mild cleanser with moisturizing properties like Cetaphil. Then apply a good hypoallergenic moisturizer over the area and see if this improves. If the symptoms still persist then you can apply mild steroid like dermacort. Topical immunomodulators can be used in severe conditions. Creams containing ceramides may be helpful in person with irritant contact dermatitis. Use of emollients, dimethicone can also be used. Use of propylene glycol, lactic acid, urea, salicylic acid which are found in many therapeutic skin products should be avoided.

If the irritation persists then please get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
