|
Opening acne lesions | This summarizes the Bezzant method of picking. My experience with trying to tell people not to pick is that it doesn't work. I, therefore, teach them this method of opening acne lesions as it seems to cause much less trauma and has less potential for scarring than picking with fingernails or with ho... | | Knowledge Weavers Dermatology |

|
Oral antibiotic | If a patient has more than 15 red papules and pustules in association with the comedos, then usually an oral antibiotic is required in addition to the previously shown therapy (see Slide 37), and I generally use tetracycline, 500 mg tid, or minocycline, 100 mg bid as the oral antibiotic choice. | | Knowledge Weavers Dermatology |
183 |
|
Papular acne | When the closed comedos rupture, they can induce inflammation seen as red papules and pustules. When these inflammatory lesions form, an antibacterial needs to be used. | Anti-bacterial Agents | Knowledge Weavers Dermatology |

Punch biopsy | Punch biopsy is excellent for sampling a skin disease that has multiple essentially identical lesions, or sampling a lesion within the skin. It is designed for full thickness skin biopsy, and is not an effective tool for biopsying the fat. When using it, it should be held as shown, should be spun ve... | | Knowledge Weavers Dermatology |

|
Punch biopsy | I gently lift the punch without pinching it and thereby creating damage to the specimen, and then snip the fatty strand that connects the skin to the underlying fat and muscle. | | Knowledge Weavers Dermatology |

|
Punch biopsy | I stabilize the skin with my non-dominant (left) hand by stretching or pinching the skin, and then holding the punch at the top and spinning it very rapidly while applying moderate pressure I very quickly obtain full thickness skin biopsy. | | Knowledge Weavers Dermatology |

|
Punch biopsy | This demonstrates anesthetizing the skin before doing a punch biopsy. The target is the epidermis and dermis, and the upper portion of the fat, and all those areas should be injected with local anesthetic. | | Knowledge Weavers Dermatology |
