The Spot Check

In this wide-ranging and deeply practical episode of The Spot Check, host Jamie Restivo, MPAS, PA-C, welcomes Cheri Frey, MD, board-certified dermatologist, residency program director at Howard University, and internationally recognized expert in evidence-based skincare, for a conversation on how cosmeceuticals and over-the-counter products meaningfully support medical dermatology.   Dr Frey begins by reframing the modern cosmeceutical landscape, emphasizing the increasing scientific rigor behind formulation development—from longevity medicine and cellular senescence to peptides and the expanding role of exosomes. She underscores that many OTC products now reflect years of clinical testing, and that dermatology clinicians are increasingly involved earlier in product conception and validation.   The discussion then turns to photoprotection, with a particular focus on visible light and hyperpigmentation, especially in skin of color. Drawing on work from Dr Henry Lim’s group, Dr Frey explains how visible light, especially high-energy blue light, stimulates melanogenesis through Opsin 3 activation, stabilizes tyrosinase, and contributes to long-lasting dyspigmentation even with standard sunscreen use. Both speakers emphasize the foundational role of tinted sunscreens containing iron oxides, which block visible light while providing cosmetic camouflage, and discuss practical considerations such as shade matching, seasonal skin tone changes, and adherence.   From there, the conversation expands into adjunctive skincare across common inflammatory conditions, including acne, rosacea, atopic dermatitis, and melasma. Dr Frey reviews the emerging role of microbiome-targeted acne therapies, such as bacteriophage-based products that selectively reduce pathogenic C. acnes without disrupting beneficial phylotypes. She also highlights barrier-supportive cleansers and moisturizers, emphasizing patient experience, tolerability, and cost accessibility as key drivers of adherence.   The episode closes with a thoughtful examination of novel pigment-targeting and barrier-repair strategies, including thiamidol as a human tyrosinase inhibitor for melasma and lentigines, DNA repair enzyme sunscreens for high-risk patients with actinic damage, and sodium hypochlorite washes as a modern, approachable alternative to traditional bleach baths in atopic dermatitis and other inflammatory conditions.   Dr Frey’s central message is clear; patients are already using OTC skincare, and when clinicians guide those choices intentionally, cosmeceuticals can meaningfully enhance outcomes, tolerability, and long-term disease control.

In this clinically deep and surprisingly modern discussion, host Jamie Restivo, MPAS, PA-C sits down with Lawrence Green, MD, board-certified dermatologist, clinical professor at George Washington University, and Chair of the National Psoriasis Foundation Research Committee, to reexamine a decades-old therapy through a fresh lens: narrowband UVB phototherapy.   Dr Green traces phototherapy’s evolution from the cumbersome Goeckerman tar regimens of the 1990s to today’s safe, targeted narrowband UVB devices (310–312 nm), which drastically limit carcinogenic wavelengths and offer a more precise inflammatory response. “Phototherapy of the 1990s is not the phototherapy we use today,” he emphasizes, calling it a niche therapy that remains the best choice for very specific patient groups.   Together, Restivo and Green outline where light treatment truly shines: guttate psoriasis, pregnancy, pediatric cases, episodic flares, extensive vitiligo, severe pruritus, and moderate plaque disease that is too widespread for topicals but not appropriate for biologics. Narrowband UVB, Green stresses, is “local therapy that leads to a systemic immune response,” allowing treatment without placing medication into the body.   The conversation then shifts to at-home phototherapy, a modality Dr Green once avoided due to safety concerns, user error, and poor adherence. That changed with modern guided systems that mimic in-office decision-making through dose-adjusted protocols, Fitzpatrick-based starting points, and real-time compliance reporting back to the prescriber. Green highlights findings from the landmark LITE study, led by Joel Gelfand, MD, which showed home treatment to be non-inferior to office-based phototherapy, equally safe, and three times more likely to be completed, across diverse skin types.   He concludes with a pragmatic reminder: clinicians no longer need light boxes in their offices to prescribe phototherapy. “Phototherapy is for everyone,” Green says. “It’s an older therapy that’s now a new therapy because of the technology… We’ve taught an old dog new tricks.”

In this episode of The Spot Check, host Jamie Restivo, MPAS, PA-C, welcomes Fabrizio Galimberti, MD, PhD, dermatologist and Medical Director at Conway Medical Center, for an engaging discussion on one of the most common yet deceptively complex conditions seen in clinical practice, actinic keratoses (AKs).  Dr Galimberti emphasizes the importance of distinguishing AKs from “dry skin,” reminding listeners that these are pre-cancerous lesions with the potential to progress to squamous cell carcinoma, which is responsible for more deaths annually than melanoma. Together, he and Restivo unpack the art and science of combining cryotherapy and field therapy, with data showing a reduced burden of both pre-cancerous and cancerous lesions when these treatments are paired. “This is a chronic condition,” Dr Galimberti notes. “We need to treat for now and for the future.”  The conversation explores how photodynamic therapy (PDT) fits into the AK treatment paradigm, offering controlled, in-office precision with cosmetic benefits and no risk of scarring. Dr Galimberti outlines his evolving patient-selection criteria, insights on optimizing incubation times, and the growing promise of painless PDT. He also shares pragmatic workflow pearls, like scheduling PDT and follow-up appointments simultaneously, to improve adherence and outcomes.  Listeners will gain a grounded, practice-ready framework for treating AKs holistically: balancing efficacy, tolerability, and patient experience while addressing both visible and subclinical disease.

In this lively and deeply informative episode of The Spot Check, host Jamie Restivo, MPAS, PA-C, sits down with Benjamin Lockshin, MD, dermatologist and Director of the Clinical Trials Center at U.S. Dermatology Partners, to unpack one of the most promising frontiers in atopic dermatitis (AD): targeting the OX40–OX40 ligand pathway.  Together, they review the AD treatment landscape and current gaps in therapies. Lockshin outlines the promise of OX40 inhibition as a potential step toward true disease modification, with less frequent dosing and durable remission that could reshape long-term disease management.  Restivo and Lockshin walk listeners through the immunologic mechanisms at play, breaking down how OX40 and its ligand function as upstream co-stimulatory molecules driving inflammation, barrier dysfunction, and itch. They compare emerging agents rocatinlimab and amlitelimab, explaining how each targets a different side of the OX40 pathway, and discuss early data showing high EASI-90 to EASI-100 responses and sustained clearance even after treatment withdrawal.  Their conversation delves into what makes these agents distinct from JAK inhibitors and biologics, emphasizing that OX40 inhibition appears to rebalance rather than deplete T cells, with minimal immunosuppression and a favorable safety profile so far. Lockshin shares practical considerations around patient selection, dosing convenience, and future applications beyond AD—including prurigo nodularis, alopecia areata, and potential oncologic uses.  The discussion closes on a forward-looking note: OX40 may be dermatology’s first real leap toward immune reprogramming. As Lockshin puts it, “good things are worth the wait,” and OX40 inhibition could mark the next chapter in changing the course–not just the symptoms—of atopic dermatitis.

The Spot Check, host Jamie Restivo, MPAS, PA-C, welcomes Scott Dinehart, MD, board-certified dermatologist, Mohs surgeon, and founder of Arkansas Dermatology, for a frank and myth-busting discussion on hedgehog pathway inhibitors (HHIs) and their role in treating locally advanced basal cell carcinoma (BCC).  Dr Dinehart, one of the first fellowship-trained Mohs surgeons in Arkansas, shares his firsthand experience with vismodegib and sonidegib, emphasizing that PAs and NPs are ideal prescribers for these agents and should feel confident managing this patient population. He addresses common misconceptions about efficacy and tolerability head-on, noting that “These drugs work—and they work in more than 90% of patients.”    Together, they explore clinical indications for sonidegib and discuss expanding the mindset beyond large, neglected tumors. Dinehart urges clinicians to consider HHIs for older adults, nursing home residents, patients with multiple lesions, or those who simply prefer to avoid surgery or radiation. “Shrinkage”, he reminds listeners, is always a win—improving quality of life and often allowing for simpler, less invasive procedures down the line.  Supplemental Clinical Resources: To support adoption of HHIs in everyday practice, Dr Dinehart has provided two references:  Sonidegib Quick Reference Sheet: summarizes key prescribing information, laboratory guidance, drug-interaction tables, and L-carnitine dosing details for muscle-cramp prevention.  HHI Dosing Calendar: a visual schedule illustrating his modified twice-weekly regimen to aid patient counseling and adherence tracking.  For clinicians who have additional questions or would like to discuss treatment approaches, Dr Dinehart welcomes inquiries at smdinehart@gmail.com.

In this extended cut of The Spot Check, new host Jamie Restivo, MPAS, PA-C, welcomes Andrew Mastro, MS, PA-C, for a deep and dynamic conversation centered on dupilumab and its broadening role in dermatologic care.  Together, they unpack the science behind type 2 inflammation and the mechanisms that make dupilumab effective across eight FDA-approved indications, including atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, bullous pemphigoid, and chronic spontaneous urticaria (CSU). Mastro offers a practical breakdown of type 2 cytokine activity and discusses how targeting these pathways drives disease control across skin, lung, and GI conditions.  The pair discuss first-line use of dupilumab in AD, emphasizing its safety profile, FDA approval down to 6 month of age, and ability to treat multiple comorbidities. They also explore new territory with bullous pemphigoid, reviewing data from the ADEPT trial, the challenges of oral corticosteroids in elderly patients, and how dupilumab might offer a safer, targeted alternative.  Mastro shares thoughtful insights on treating prurigo nodularis, advocating for aggressive, empathetic care and cautioning clinicians not to delay treatment as a biopsy is not necessary to make this diagnosis. He stresses the importance of documenting thoroughly and recognizing PN even in the absence of nodules.  The episode concludes with a discussion on chronic spontaneous urticaria (CSU), including diagnostic criteria, evolving treatment approaches, and patient expectations. They push back on outdated, exhaustive lab workups and advocate for focused history-taking and up-dosing antihistamines before initiating biologic therapy.  With clinical pearls throughout—including how to frame conversations with patients about long-term therapy, how to document for coverage, and when to lead with systemic options—this extensive conversation offers a masterclass in therapeutic decision-making, delivered with humor, heart, and high-level clinical insight.
