What make-up should I use, Doctor?

This is an exceedingly common question among my female patients. Most women know to use only non-comedogenic and oil free products to avoid clogging pores and producing acne but still have questions regarding the ideal make-up to use. Along with many other dermatologists, my resounding response is to utilize a mineral based make-up usually in a loose powder form.

A number of mineral based make up products are currently available including the following brands:  Bare Minerals, Bare Escentuals, Glo Minerals, and Jane Iredale just to name a few.

Tareen recently relocated from New York, where she worked at a high-end Manhattan practice. In addition to being an adjunct professor at the University of Minnesota’s Medical School and an expert for, Tareen is launching cosmetic services such as Botox and fillers at the Ivy Spa in Minneapolis.

There, she’ll help Minnesotans capture her same impossibly fresh look.

“Small, subtle things make a huge difference,”  she said. “I don’t want somebody to say, ‘What did you have done?’ I want somebody to say, ‘You look well rested.’ ‘You look like you got a great haircut.’ ‘You look like you went on vacation.'”

My patients are always surprised when I check their fingernails and toenails for skin cancer. “Doc, you can even get skin cancers under your nails?” is the typical question. Indeed, although rare, it is possible to get skin cancers, and even deadly forms of melanoma under the nail.

If Hutchinson’s sign is present, a biopsy should be performed urgently.   Continue reading
