As a light skinned, be-freckled woman with a history of pre-melanoma, I have been sternly instructed to keep my dermatologist on speed dial. Every six months I dutifully return to his office for inspection — nervously eyeing the biopsy tray as I sweat through my paper gown, legs dangling from a vinyl exam table.

In preparation for my most recent trip, I decided to be “an empowered patient” and arrive with a list of general dermatology and skin care questions that could be answered during my skin check. Judging from the near-syncopal episodes that I induced in my dermatologist while describing some of my hygiene practices, I’m not being very good to my skin. In fact, he wanted me to know that at least three products that I currently use are “of the devil.” Just in case you are inadvertently engaging in demonic skin care practices as I was — I thought I’d share what I learned:

1. Dryer sheets. According to my dermatologist, dryer sheets contain “a horrible chemical that no one can pronounce” that becomes “slathered all over your clothing” during the drying process. Although I was fond of the fresh scent and soft texture of my gym clothes, he assured me that heat and moisture was the best way to re-activate the irritating chemicals on delicate skin, virtually guaranteeing a contact dermatitis of the nether regions. So if you’ve been experiencing any unpleasant post-work out skin “issues” — consider dryer sheets as a potential cause.

2. Antibacterial ointments. Personally, I find that over-the-counter antibacterial ointments do a great job of preventing razor bumps. However, my dermatologist says that repeated or excessive use of these products can lead to allergies and colonization with antibiotic-resistant organisms. So unless you want to be giving MRSA a “come-hither stare,” you might want to opt out of the Neosporin.

3. Battery-operated exfoliating brushes. I’ve seen so many ads for Clarisonic-type products that I figured they would be a reasonable choice for facial exfoliation needs. In fact, this topic may be somewhat controversial since I know other doctors who recommend these products. However, my dermatologist says that they are overkill and might do more harm than good to delicate facial skin, especially if you use any products that have an exfoliating acid included in their ingredient list, or if you use scrub creams. In other words, if you wash your face regularly, you probably don’t need to use additional aggressive cleaning measures.

In addition to the information provided about evil products commonly used by innocent people across America, my dermatologist offered these general tips for healthy skin:

1. You don’t need so much moisturizer. “You don’t need to put on moisturizer every night just because your mother told you to,” he said, bow tie looming large at eye-level. “Women think they need to apply moisturizer multiple times a day, but there is enough moisturizer in sunscreens and anti-oxidant serums to make additional products unnecessary.”

2. Throw away your 10x mirror. “Honestly, no one sees your skin at 10x, so why should you worry about what it looks like so close up? The best way to make your pores look smaller is to quit looking at them under a magnifier.”

3. Use physical block sunscreen every day. Most of the cheaper, spray-on sunscreens use chemicals to scatter light, but zinc-based sunscreens physically block incoming UV radiation. “The most important part of an ‘anti-aging’ regimen is to avoid sun exposure, and the best way to do that is with constant use of physical blocks.”

4. Skin-lightening cream (hydroquinone) can reduce the appearance of sun damage. Hydroquinone is the active ingredient in most skin-lightening creams. It acts to down-regulate melanin production in melanocytes, but can be reversed fairly easily by UV exposure (i.e. sunlight up-regulates melanin production). So even if you’re already pale-skinned, hydroquinone products can even out skin tones and sun spots – but only if you simultaneously commit to aggressive avoidance of UV exposure.

I hope you’ve found these skin tips enlightening (pun intended). I’ll have to think of some other good questions to ask my dermatologist in 6 months from now, during my next cancer screening. Because as an empowered patient, I intend to learn as much as I can in my 15 minutes with the doctor, and then share it with as many people as possible.
