Dr. Pimple Popper 101

Dr. Pimple Popper 101

IF YOU ARE A REGULAR VIEWER OF MY YOUTUBE CHANNEL, YOU WATCH ME address all kinds of skin-related topics, using specific medical terms. I tend to stick with what works, the tried and true, but, of course, I have learned many things along the way. Here I’m going to give you a crash course in Dr. Pimple Popper and some skin basics. This will set you up for what follows in the rest of the book and give you a chance to think about your own skin. It’s important when you read Put Your Best Face Forward that you don’t think I’m speaking a foreign language! Just as people use the metric system to talk about measurements, dermatologists use their own special terms to understand and communicate skincare concerns and concepts. These important terms and techniques help you understand the different conditions and treatments I refer to in the book and on my social media. This guide can even help you to understand your own skin better, and to discuss questions and concerns with your dermatologist. (They’ll be impressed by your new vocabulary!)

Dr. Pimple Popper


  • MACULE: This completely flat lesion on the skin measures less than 1 centimeter in diameter and can be any color of the rainbow. A good example is a freckle or a flat mole. When you run your finger over it, you don’t feel any change in the surface of the skin.
  • PATCH: A patch is flat just like a macule, only larger (greater than 1 centimeter in diameter). Examples include vitiligo (white patches where pigment cells have been destroyed), melasma, and a large, flat birthmark.
  • PAPULE: An elevated, raised, well-rounded growth projecting from the skin’s surface that is less than 1 centimeter in diameter. This is different from a blister, a vesicle, or a pustule. Good examples are a raised mole, a cherry angioma, a seborrheic keratosis, and a wart.
  • PLAQUE: This is what we call a papule that is greater than 1 centimeter in diameter. Again, it’s elevated and well circumscribed. Psoriasis is commonly described as plaque-like growths, but many other dermatologic conditions appear as plaques.
  • NODULE: A raised growth under the skin, but it is deeper seated and not as superficial as a papule. You popaholics know this well. A nodule is often at least 2 centimeters in diameter, or about the size of a penny. We use this term to describe lesions such as cysts, lipomas, keloids, and two common skin cancers, basal cell carcinoma and squamous cell carcinoma. See, I taught you something without your even knowing it!
  • VESICLE: A raised, well-circumscribed growth, less than 1 centimeter in diameter, but primarily filled with a clear liquid. This is what we see in cold sores (herpesvirus), chicken pox, and shingles.
  • BULLA: This is something many of you popaholics would get excited to see, because it’s essentially a big blister; a large, water-filled vesicle greater than 1 centimeter in diameter. This is how we describe a friction blister (the type of blister we get from ill-fitting shoes), and also, we see it in many blistering disorders of the skin.
  • PUSTULE: An elevated, circumscribed growth that is much like a vesicle, but instead of being filled with a clear liquid, it is filled with a purulent fluid, pus. This is seen in acne.
  • CRUST: A layer of dried sebum (an oily substance secreted by the sebaceous glands located in the skin and often attached to hair follicles), pus, or blood mixed with epithelial (tissue) or bacterial debris.
  • SCALE: An excess buildup and/or shedding of stratum corneum, the outermost layer of the skin.
  • FISSURE: A linear crack in the skin, which can often be quite painful. You may get one or more of these on the heel of your foot or even on your tips of your fingers when the areas are irritated.
  • EROSION: A superficial open wound with loss of skin.
  • ULCERATION: A deep open wound with a partial or sometimes complete loss of skin and even deeper structures.
  • EXCORIATION: Loss of skin due to picking or scratching.
  • ATROPHY: A thinning of the epidermal or dermal tissue.
  • LICHENIFICATION: An increase in skin lines and creases as a result of chronic rubbing.

The Truth About Tumors

When many people hear the word tumor, they automatically think of something malignant (cancerous) and life threatening. I think of that scene in the movie Kindergarten Cop where Arnold Schwarzenegger yells to the kids, “It’s not a too-mahhhhh!!” Actually, tumor is a generic term, simply meaning a growth on the skin or on an organ within the body. We refer to nonmalignant tumors as benign. So don’t let the word tumor frighten you!



I probably get the most complaints about posting video footage of numbing procedures, including videotape of my administering anesthesia with a needle and syringe. It gives many people more heebie-jeebies than the purulence, or pus, that emits from an abscess does! But it’s important you see what I do here.

I would certainly argue that dermatologists are the best compared with any other medical specialty when it comes to administering local anesthesia with the least amount of pain and discomfort possible, since we do this on a daily basis. I actually perform many maneuvers at the same time when I stick someone with a needle. I know that this is one of the main reasons why some people avoid going to the doctor: they are afraid of needles. My ultimate goal is to anesthetize patients painlessly—in fact, to numb them before they even realize I’m doing anything at all to their skin—because it instills trust between patient and dermatologist. Here are several of my favorite techniques:

  1. HIDE THE SYRINGE: Needles are not on display in my office. They are hidden in my pocket or held close to my side, passed to me on the sly by my assistant—certainly not waved in front of patients to increase their anxiety.
  2. I’M “BASIC”: Numbing medication such as lidocaine is acidic, which is why it burns when we inject it under the skin. We temper this burning sensation by adding sodium bicarbonate to the mix. NaHCO3 raises the pH of the liquid, reducing the acidity and thus making the injection more comfortable.
  3. 30-GAUGE NEEDLE ONLY: I don’t use any needle thicker than a 30-gauge, which is very thin: not much wider than the size of a single hair. Because the smaller the needle, the smaller the pinch; the smaller the pain, the smaller the hate.
  4. SHAKE OR PINCH THE SKIN WITH MY NONDOMINANT HAND: This is an important one, and one that draws a lot of attention on my videos. People watching sometimes think I’m nervous or have a tremor. I don’t. I’m actually doing this purposefully.
  5. INJECT SLOWLY AND TAKE ADVANTAGE OF FIELD EFFECT: This is actually something I don’t think a lot of physicians realize if they don’t inject as often as we dermatologists do all day, every day.
  6. TALK-ESTHESIA: An important one. I don’t think I’m actually a chatterbox in real life. (I’ll bet that many of you who’ve watched my videos find this hard to believe.) But I ask open-ended questions, or just chatter on about current events or even about myself, to distract the patient from the task at hand, including the sounds that the scalpel makes as it cuts the skin and the “sliding” sound of the suture (stitch) that passes through the skin. Also, if a patient is formulating an answer to one of my questions, his or her focus is no longer on the surgery. It’s all about distraction, and it works.


These are the two main types of surgical blades I use. The 11 blade is what I rely on instead of lancets (small, short pins), because it comes to a very sharp point and allows me to nick the skin very superficially to cause as little damage as possible before I extract a whitehead or milium. I use a 15 blade in surgeries to excise tissue before I place sutures, or to shave off a layer of skin to send for a biopsy.


There are so many different types of comedone extractors, but the Schamberg-type tool is really my jam. It avoids excess trauma to the skin and allows controlled, even pressure around blackheads or milia in order to best extract them efficiently.

The comedone tweezer is something I’ve discovered myself because of—guess what?—social media! I, too, was transfixed by videos that I saw on Facebook and Instagram of a physician using a curved tweezer to push against the skin and then to pull out completely the extruded blackhead. I’ve tried it out, and I like it, but it doesn’t replace my original comedone extractor. It’s also particularly satisfying to pull out sebaceous filaments using these funky-shaped tweezers designed specifically to get into tight spaces and pull gently from the skin stuff that shouldn’t be there.


Many of you ask me how I decide which approach to use in removing a cyst: whether to excise the area or to pull out the “punch” biopsy tool that so many of you are enamored of. Well, it has everything to do with the size of the cyst, its location, and my mood that day. In other words, there are many instances when I can do either a punch or a standard elliptical excision, but let me explain my criteria for choosing one option over the other.

In all instances, I could perform a standard elliptical excision, but sometimes the punch excision is quicker, which is partly why I may choose it. First, you should understand that this circular cookie-cutter-type tool is traditionally used to take a skin sample (biopsy) when the goal is to obtain a deeper component of skin, as opposed to a shave biopsy, where we merely take off the superficial layer. We also use the shaving technique to take off a mole sitting up on the skin, so that the area is left flat and flush with the regular skin.

The punch biopsy tool takes a core of tissue so that we can assess the dermal and subcutaneous tissues, the deeper components of the skin. In the case of cyst removal specifically, I use the punch tool to create a larger opening in the cyst so that I can squeeze out its contents and keep the surgical repair line short. Punches come in many different sizes, from as small as 1 millimeter to probably as big as 2 centimeters or so. There are even elliptical-shaped punches (which I don’t use because you can’t cut through the skin with a twist, as the tool is not circular). It’s important to understand that the larger the circular punch, the more difficult it is to close the resulting wound from side to side without creating “dog ears” or “Burow’s flaps”—that is, pooching up of the outer edges of the surgical wound.

This is actually why excisions are elliptical or diamond shaped. Seamstresses understand this concept, as they know that a circle cannot be sewn together without getting bumpy, but “darts” have to be created on the outer edges so that the clothing will lie flat. This is why I perform punch excisions of cysts only if the sacs are on the smaller side. I really use only punches that range in size from 2 millimeters to 5 millimeters; any larger than, say, 6 millimeters, and the dermatologist will need to convert to a more elliptical excision, so I might as well do that in the first place!

Location is also important when determining punch versus standard excision. Areas with thinner and more mobile skin and areas that are generally covered by clothing would be possibly punchworthy. You really won’t see me doing a punch on the face unless the skin is really loose and movable, as in the case of an older gentleman with thin cheek skin. Elliptical excisions are more elegant and cosmetically superior. I don’t use a large punch excision on the thick and stiff skin of the back in a large person because a slit excision may be preferable: any wideness to an excision has to be pulled together, and the more tension that is created, the wider the excision, with increased risk of the scar spreading and an inferior cosmetic result.


Before I “became” Dr. Pimple Popper, I was handling maybe ten cyst excisions a year; now I probably do about that much in a week. Needless to say, I’ve gotten better at preparing and predicting cyst behavior, improving the final result, and decreasing the incidence of recurrences. There’s actually a video on my YouTube channel that shows the moment I realized that the curette would be pretty useful when ensuring the complete removal of cysts. The curette is a standard instrument used by medical dermatologists, but most commonly, it’s for scratching or scraping off lesions that grow atop the skin—particularly seborrheic keratosis. I also use a curette to clean out the “hole” at the excision site, to ensure that the entire cyst and cyst wall have been eliminated. Leaving behind any tissue from the cyst wall heightens the risk of a recurrence.


As with politics, this is a divisive topic. Some people prefer watching messy cyst extractions; others prefer watching a cyst excised completely cleanly and intact. I just wonder if one group is composed more of Democrats and the other of Republicans. But as a physician, I always stay away from the topic of politics! Personally and professionally, I prefer a clean extraction, mainly because this reduces the odds of the cyst recurring. Also, as you have seen from my videos, the contents of a cyst sac can be all colors of the rainbow, chunky like cottage cheese or egg salad, creamy like mashed potatoes, or thick and sticky like oatmeal or wet newspaper.

I know you’re not grossed out if you’re a popaholic! In addition, I have learned that the larger the cyst size and the longer it’s been around, the more likely the contents have liquefied somewhat, so if this cyst is opened rather than removed intact, it can create quite a mess. And you guys don’t have smell-o-vision, but you often comment on this; you both want to know and don’t want to know what the contents of the cyst smell like. Well, in general, we in the room don’t want to know, so if we avoid opening up the cyst, we minimize any odor detected.

What do these pops smell like? Not all of these growths I pop out from the skin smell, but like I say all the time, I don’t really try to smell them! We all wear masks, and I would say that smell is not my dominant sense. (Thank goodness in this case.) However, I know that so many of you people are curious about this, so let me give you the best idea, and maybe one of these days I can create a scratch-and-sniff that you guys can get and see for yourself! First of all, it’s mainly epidermoid cysts and infected cysts that have a strong odor. But not all epidermoid cysts have a strong smell. Lipomas don’t smell; they look like raw chicken breast, so I’m guessing if I stuck my nose real close and took a whiff, they would smell like that?

But trust me, I’m not trying this anytime soon. Pilar cysts often don’t give off an odor. However, noninflamed epidermoid cysts can certainly emit a pungent odor that often stays with you hours later, and I’m always reminded that the reason we smell things is because tiny microparticles actually escape into the air and get caught in our nasal passages and nasal hairs, so we are actually inhaling and ingesting odors in order to “smell” them. Gross, huh? Thought I would share that with you. Since I have to deal with that unnecessary and regrettable knowledge, so should you!
