Flexure rash, commonly found in the underarms, groin area, under the breasts, or in the folds of the tummy. Also known as intertrigo or flexure psoriasis, which are heat related, moisture related, and often aggravated by yeast and bacterial overgrowth.


For this group of symptoms, Dr. Harlan typically treats his patients with the following routine:

First, Dr. Harlan has his patients apply diluted, vinegar-soaked cotton compresses to the affected areas for 10-15 minutes.

Next, he tells them to remove the compresses and apply SmartLotion® to the affected areas as a thin, disappearing layer. If needed, he recommends using a hair dryer to dry the area.

He has his patients repeat this routine 2x per day for up to 2 weeks.

For the vinegar solution, he recommends the following: Mix 2 tablespoons of white vinegar into an 8 ounce glass of water.

For some cases, he will prescribe an Econazole product, or which works extremely well when combined with SmartLotion®.

Additionally, for best results, he recommends to combine his suggested routine with an antimicrobial wash.

Dr. Harlan also says that OTC clotrimazole cream and miconazole cream work well for these symptoms when applied as a thin, disappearing layer at the same time as the SmartLotion® application.


To prevent flexure rash symptoms from returning, Dr. Harlan instructs his adult patients to apply SmartLotion® 1x per day, or less as needed.
