At Pure Dermatology, I see a lot of patients with atopic dermatitis (eczema), both young and old. In Austin, there is a big focus on natural therapies and lifestyle changes to try to improve skin diseases. One question that frequently comes up is how diet can impact atopic dermatitis (AD). This chronic inflammatory skin disease affects up to 20% of children and 4-5% of adults worldwide. While we understand that AD is influenced by both genetic and environmental factors, new research is shedding light on an unexpected contributor: sodium intake.

Warts, caused by the human papillomavirus (HPV), are one of the most common dermatological issues we see at Pure Dermatology. They are also one of the most stubborn and challenging conditions to treat. While we use a variety of treatments to tackle warts such as cryotherapy, immunotherapy, salicylic acid, and laser therapy, there may also be a role for oral supplementation. In the world of warts, anything we can do to improve the odds of ridding our patients of these annoying infections is worth it. Here, we’ll talk about some of the oral supplements we sometimes recommend to patients and set realistic expectations on their effectiveness.

Hidradenitis Suppurativa (HS) is a chronic, inflammatory skin disease characterized by recurrent, painful nodules, abscesses, and sinus tracts. These lesions primarily occur in areas of the body where skin rubs together, such as the armpits, groin, buttocks, and under the breasts. HS can significantly impact a patient’s quality of life due to its painful symptoms and the psychological impact of its visible lesions and scarring. Patients are often told they are “dirty,” but the reality is this condition is often genetically driven. Despite affecting up to 4% of the population, treatment options for HS are limited. Currently, the only FDA-approved medications for HS are adalimumab and secukinumab, both of which are systemic therapies. This highlights a significant unmet need for more targeted, effective treatments.

Scalp folliculitis is a common inflammatory condition affecting the hair follicles on the scalp that is usually characterized by small, itchy pustules. It can be uncomfortable and distressing for those who experience it. Even more frustrating, many times these patients are misdiagnosed with seborrheic dermatitis, and prescribed antifungal shampoos without benefit. Here, I’ll aim to address what scalp folliculitis is, what the possible cause is, and available treatment options.

As a dermatologist, I see isolated eyelid dermatitis at least once a week in my clinic. This common condition can be both bothersome and distressing due to the sensitive and visible area it affects. In this post, I want to provide comprehensive information about eyelid dermatitis, including its causes, symptoms, and treatment options. Specifically, I want to focus on allergic contact dermatitis (ACD) of the eyelids, the most common cause of eyelid dermatitis.

Fungal acne has been gaining more attention in the past few years because the condition can mimic traditional acne (acne vulgaris) but does not respond to the same treatment. Fungal acne is also known as pityrosporum folliculitis or Malassezia folliculitis and has a history of being misdiagnosed by those unfamiliar with the entity. Unlike traditional acne, fungal acne is caused by an overgrowth of the yeast, Malassezia, within the hair follicles. Understanding its unique characteristics, causes, and treatments can help you effectively manage this condition. If you’ve been diagnosed with traditional acne and do not seem to be responding to traditional treatments, it may be time to ask your dermatologist if they’ve considered fungal acne.

As a consumer, you may have heard of lanolin, an ingredient derived from sheep’s wool and found in numerous cosmetics and personal care products. While lanolin has numerous benefits such as retaining moisture in the skin and reducing transepidermal water loss, it was named the allergen of the year in 2023 by the American Contact Dermatitis Society (ACDS) because of its widespread use and increasing recognition of its ability to cause contact dermatitis.

Rosacea is a chronic skin condition characterized by facial redness, swelling, and acne-like eruptions that can cause significant discomfort and emotional distress. While the precise causes of rosacea are multifactorial, factors like neurovascular abnormalities, immune system dysregulation, and environmental triggers play crucial roles. At Pure Dermatology, we see rosacea often, and the condition can be difficult to treat. Botox for rosacea has emerged as an exciting new therapeutic option.

Melasma is a pigmentary skin condition that affects over 1% of the population. In certain populations, particularly dark skin toned patients of reproductive age, this rate is even higher. As a dermatologist with a darker skin tone and pigmentary issues themselves, I know how important these concerns can be for someone of skin of color. In my clinic, melasma is one of the most common pigmentary conditions I see. Today, I’m going to briefly review melasma, go over the importance of using a broad-spectrum tinted sunscreen for melasma, and then provide some tips on picking one.
