Acne and Rosacea

BLU-U at Minnesota DermatologyAcne and rosacea are two of the most common conditions in dermatology. They can, at times, be disfiguring and leave permanent scarring. We have many effective medications to combat acne and rosacea. For comedonal acne (whiteheads and blackheads), one of the first line treatments is a retinoid. The over-the-counter versions of retinoids are often ineffective. There are several different strengths in several different vehicles (creams and gels mostly) that we can tailor to your skin and your condition's severity. Topical antibiotics and other topical medications (such as Aczone, a dapsone medication, Finacea, an azelaic acid, and several sulfa-containing lotions) can also be helpful. For the deeper, cystic acne, we often use oral antibiotics. Occasionally we will use anti-male hormone medications such as spironolactone. BLU-U light therapy can be helpful for many acne and rosacea cases. For more resistant cases, Accutane (isotretinoin) is very useful, but the risks and benefits as well as your medical history must be weighed carefully before starting it. Lifestyle changes can also be an important part of treatment, and we will discuss this in detail with you as appropriate to your specific condition.

Melasma, Age Spots, and Lentigos

Age spot, Lentigo, and Melasma TreatmentsAlthough benign, these conditions are among the most concerning for patients. The dark, sometimes splotchy areas that sun damage leaves behind are unwelcome, particularly on the face. Sometimes hormones can play a role, but the sun nearly always plays a significant role. The first step is to use appropriate sun protection (broad spectrum UVA/UVB sunscreen) to protect from further damage. There are many approaches to treating these conditions, which include topical therapy, laser, cryotherapy (liquid nitrogen) and peels. A common and very effective approach is to do a series of peels, then follow up with a maintenance topical kit to maintain your good results. These kits can be used by themselves as well, without peels, often with great results. The photo shown here is of one of our patients who used the Glytone® Clarifying Kit alone, with before and after photographs (about 4 weeks apart) demonstrating near-clearance of her melasma. She started seeing results at week 1. Although the diagnosis and consultation for these conditions are covered by your insurance, most of the treatments for melasma, lentigos, and age spots are not covered. However, there are affordable options for any budget.

Psoriasis and Eczema (Dermatitis)

Narrowband Phototherapy at Minnesota DermatologyPsoriasis and eczema are two common chronic inflammatory conditions of the skin. While there is no cure for either condition, we have many medications and treatments that can control them remarkably well. For more mild cases, we often use topical corticosteroids. At times, Protopic (tacrolimus), Elidel (pimecrolimus), Dovonex (calcipotriene), or Vectical (calcitriol), non-cortisone topical alternatives, will be appropriate. For more severe or refractory cases, phototherapy (narrowband UV-B light treatments) can be very effective. We have a certified narrowband unit on the premises. Systemic medications may be necessary. We have a lot of experience treating with the newer modalities such as the biologics (Embrel, Humira, among others) as well as the older, more traditional therapies.

Actinic Keratoses

Photodynamic Therapy at Minnesota DermatologyActinic keratoses are pre-cancers. They often feel like small hard bumps on the sun-exposed skin. Depending on the study, 3-5% of them can go on to become true skin cancers, and so treatment is recommended. We often use cryotherapy (liquid nitrogen) to destroy them. However, when you have many of them, further treatment may be recommended. There are topical medications available such as Efudex and Carac (topical 5-fluorouracil), but these can have significant downtime. A newer treatment modality, called photodynamic therapy (PDT), can be used with equally good results and little to no downtime. At Minnesota Dermatology, PDT is available.


Warts are very common and can be difficult to eliminate. There are many treatment options for warts, and most do require several visits. Cryotherapy in the office tend to be much more effective than over-the-counter "freezing" treatments. Candida (a yeast) antigen can be very effective against stubborn warts. Canthacur, a blister beetle "juice," is often used to supplement the scraping and cryotherapy technique, or can be used as a single treatment. Other modalities include hyfrecation (cautery), excision, and laser.


Molluscum cantagiosum affect the young and the old alike. In kids, we often will use Canthacur, a blister beetle "juice." This tends to cause little, if any, pain. In adults, curetting can be among the most effective treatments. We will sometimes recommend topical regiments as well.

Hair Loss and Nail Disease

Hair loss (alopecia) and nail problems are some of the most concerning conditions for patients, and rightfully so. At Minnesota Dermatology, we evaluate them and recommend the appropriate treatments. Sometimes testing is necessary, which can include biopsies and/or blood tests. Some conditions are quite curable or at least treatable, while others can be slowed but not necessarily stopped. Often, it is important to recognize the condition and start treatment early to prevent progression.


Rashes can be some of the most perplexing and interesting conditions in dermatology. Some of them are easy to identify without further workup, including "textbook" tinea versicolor, granuloma annulare, and pityriasis rosea. Others require blood work, cultures, scrapings, and biopsies to come to a firm diagnosis. Some are caused by viruses, others by medications, and still others are inherent or acquired conditions.

Moles (Nevi)

ABCD's of MelanomaMoles can be difficult, even for the most seasoned dermatologist, to evaluate. We often employ a 7-point list in evaluating concerning nevi with a dermatoscope or DermLite device. These devices help to visualize the nevus better, allowing a deeper look into the skin and seeing the pigment network and other features. You can help yourself by checking your skin once every other month or so, looking for the ABCDE's of melanoma (A- asymmetry, B- atypical borders, C- many colors within a lesion, D- diameter larger than a pencil eraser, E- evolution or changing over time) and returning to clinic with any worrisome lesions. We do many skin cancer screening exams to professionally evaluate your skin and moles at Minnesota Dermatology.
