Rare Skin Infection May Spread to Other Areas
Researchers reported a case of a rare skin infection caused by a fungus called Trichophyton rubrum. This fungus is usually harmless but can cause problems in people with weakened immune systems. In this case, the infection spread to other areas of the body and caused multiple ulcers and abscesses.
Why it matters: This case study may help dermatologists better understand how this rare infection can progress and how to treat it.
This study is a case report and involved a single patient, so the findings may not be representative of all cases. The patient had a history of immunosuppression, which may have contributed to the severity of the infection.
◆ Notable findingA finding from a controlled trial, systematic review, or meta-analysis with noteworthy results.Systematic ReviewSummary and analysis of existing published studies.RetinolAcnePublished: March 18, 2026
Researchers reviewed the causes and effects of post-inflammatory hyperpigmentation (PIH), a condition that can occur after skin injuries or diseases. They found that PIH is a complex condition with multiple pathways involved, and it can be challenging to treat. The study highlighted the need for prompt diagnosis and management to prevent long-term effects.
Why it matters: Understanding PIH may help individuals with skin conditions or injuries to prevent or manage its effects.
The review is based on existing knowledge and may not reflect the latest research findings. High-level clinical evidence for treatment options in PIH remains limited.

Updated Acne Treatment Guidelines Released
Researchers updated guidelines for treating acne, focusing on when to use isotretinoin, antibiotics, and hormonal treatments. The guidelines also cover the use of new topical treatments and the safety of benzoyl peroxide. The recommendations are based on current evidence and expert consensus.
Why it matters: These guidelines may help healthcare professionals make informed decisions about acne treatment, which can improve patient outcomes.
This guideline is an update of the 2016 version, and all other aspects remain unchanged. The guideline group prioritized three key clinical questions and provided revised recommendations based on current evidence and expert consensus.

New Framework May Help Improve Skin of Color Education in Dermatology Residency Training
Researchers developed a framework called SoC-TEQ to evaluate how skin of color education is taught in dermatology residency training. The framework assesses three domains: teaching exposure, instructional quality, and resident engagement. It aims to improve skin of color education through resident-led feedback and peer-led remediation.
Why it matters: This may help improve dermatologists' understanding and treatment of skin of color conditions, potentially leading to better patient care.
This study is a framework development study, not a clinical trial. Its effectiveness in improving skin of color education has not been tested yet.

Chronic Hand Eczema: A Complex Interplay of Genes, Environment, and Exposures
Researchers studied chronic hand eczema to understand its causes and how it affects people. They found that it's a complex condition with multiple factors at play, including genes, environment, and exposures. The study suggests that immune pathways and skin barrier function are involved, but more research is needed to understand the differences between subtypes.
Why it matters: Understanding the causes of chronic hand eczema may help develop new treatments and improve quality of life for those affected.
This study focused on chronic hand eczema and did not investigate other skin conditions. The findings are based on a limited number of participants and more research is needed to confirm the results.

Oral Doxycycline's Effectiveness for Acne Treatment Compared to Other Options
Researchers studied the effectiveness and safety of oral doxycycline for treating acne vulgaris by comparing it to other treatments. They found that doxycycline showed similar results to azithromycin, but other treatments like isotretinoin and silymarin seemed to work better. However, doxycycline also had more side effects.
Why it matters: This study's findings may help skincare professionals and patients understand the pros and cons of using oral doxycycline for acne treatment.
This systematic review included 23 randomized controlled trials with 2,672 patients, but the quality of the evidence and the risk of bias across studies were not explicitly evaluated in the abstract.
SkinCareRadar is a public research monitor focused on skincare ingredients, routines, devices, and skin concerns. It translates dermatology and cosmetic science research into plain language for the general public.
Every finding is linked to its original source. Evidence stages are labeled clearly. We do not diagnose, recommend treatment, or give medical advice. We distinguish cosmetic improvement from medically significant outcomes.
