RESUMEN
BACKGROUND: The use of ointments can be beneficial for dry, chapped, or cracked skin and also for supporting wound healing. We describe the results of 2 studies with an over-the-counter healing ointment (HO) to evaluate the effects on skin hydration and in the setting of wound healing after dermatologic procedures. Methods: Study 1 was a single-center, in-use study using HO on qualified areas at least once daily for 4 weeks in subjects with dry, cracked body skin and self-perceived sensitive skin. Study 2 was a multi-center study of wound healing in subjects using HO on a daily basis after having dermatologic surgical procedures. Results: In Study 1, there was a significant reduction in skin dryness after 1 and 4 weeks of HO use (P<0.05). Image analysis of the skin revealed a significant increase in skin smoothness after the first application of HO in 100% of subjects (P<0.05). Tolerability and safety were excellent, and HO was well-perceived by subjects throughout the study. In Study 2, HO improved clinical assessments at all time points compared with baseline with a decrease in erythema, edema, scabbing/crusting, and an improvement in overall wound appearance (P<0.05). There was no worsening or significant increase in measures for tolerability parameters at any study visits. Additionally, HO achieved a favorable perception by study subjects. Conclusions: HO has a well-established safety profile and has been shown to improve both skin hydration and the overall wound healing process after dermatologic surgical procedures.

Necrobiosis lipoidica (NL) is a chronic granulomatous disorder of the skin which usually presents with red papules and plaques on the lower extremities. Diabetes mellitus has been found to be associated with NL, but the pathophysiology of the disease is unknown. Based on a Doppler flowmetry study showing increased blood flow at NL lesions and the macrophage upregulation of granulomatous disorders, it is reasonable to conclude that there is an inflammatory component to it. NL is extremely challenging to manage. The initial treatment of choice is usually topical or intralesional corticosteroids, and if this fails to work, many dermatologists depend on the small number of case reports for more treatment options. We present a pre-diabetic patient with nonulcerative NL who was successfully treated with the first-in-class therapeutic aryl hydrocarbon receptor (AHR)-modulating agent tapinarof cream (VTAMA, Dermavant). Following the case presentation is a discussion of this topical novel agent and its unique anti-inflammatory mechanism of action. Tapinarof specifically binds to and activates AHR leading to downregulation of TNF-α/IL-23/IL-17 and inhibition of IL-4/IL-13 mediated STAT6 activation. Anti-TNF-α agents and JAK-inhibitors have also been found to be beneficial in treating NL; tapinarof seems to target both these pathways without the risk of their serious adverse reactions.
