Vitamin C promotes cell proliferation to thicken skin

1 day ago | derm.city | John Evans

Researchers in Japan have discovered that vitamin C helps thicken the skin by directly activating genes that control skin cell growth and development. Their findings, published online in the Journal of Investigative Dermatology, suggest that vitamin C may restore skin function by reactivating genes essential for epidermal renewal.
Skin barrier health a potential biomarker for eosinophilic esophagitis

1 week ago | derm.city | John Evans

New findings suggest that the skin may serve as a potential biomarker for a chronic allergic disease of the esophagus—eosinophilic esophagitis (EoE)—in children. The results provide physicians with a potential new, non-invasive avenue to diagnose EoE using skin tape. This study by Elena Goleva, PhD and Donald Y.
Ninth annual Walk for Camp Liberte

2 weeks ago | derm.city | John Evans

On June 11, 2025, Chronicle Companies joined Galderma Canada for the 9th annual Walk for Camp Liberté, raising money to send children with moderate to severe skin disease to the specialized summer camp. Camp Liberté is an independent charitable organization run by volunteer Canadian dermatologists. Their mission is to provide children with moderate to severe skin disease with the opportunity to take part in an outdoor camping experience in a bilingual and supportive environment.
Dog ownership may mitigate one genetic eczema risk factor

3 weeks ago | derm.city | John Evans

Findings from a new study suggest early-life exposure to domestic dogs may modify the effect of one genetic risk factor for atopic eczema (AE)—a single-nucleotide polymorphism known as rs10214237. This finding supports observational epidemiology that has shown a protective effect of dog ownership against AE.
Skin cancer rates growing among older males

4 weeks ago | derm.city | John Evans

New findings show the global burden of skin cancer in the older population is growing, particularly in males and those living in high sociodemographic index (SDI) countries. However, much of this growth is driven by an increase in the overall population. The study, published in JAMA Dermatology (May 21, 2025, online ahead of print), evaluated the global burden of skin cancer among adults 65 years or older from 1990 to 2021 and projected the change in this burden by 2050.
AD biologic non-responders benefit from extended Tx

1 month ago | derm.city | John Evans

New research reveals that patients with moderate-to-severe atopic dermatitis (AD) who did not initially respond to biologic treatment with lebrikizumab may still achieve significant clinical improvements with continued therapy. The findings, published in the Journal of the American Academy of Dermatology, highlight the efficacy of extended lebrikizumab treatment up to 52 weeks and suggest a potential approach to more personalized, patient-centered management of AD.
Sun protective behaviours declining in Canada, U.S.

1 month ago | derm.city | John Evans

Findings from a Canadian study show that despite decades of public health messaging, Canadians are spending more time in the sun and using less sun protection, even as melanoma rates are rising. Similarly, an American Academy of Dermatology (AAD) survey has revealed low rates of sun protective behaviour, even though half of Americans are concerned about skin aging.
Melanoma rates growing among New Zealand’s Māori

2 months ago | derm.city | John Evans

Rates of melanoma skin cancer among the Māori population are growing in New Zealand, the nation with the highest melanoma mortality rate in the world, said Dr. Monique Mackenzie (Ngāti Tūwharetoa) in a presentation at the first annual Indigenous Skin Spectrum Global Summit. As with many other darker-skinned populations, the Māori tend to present later, with greater Breslow thickness and have poorer outcomes. However, research in this population faces several challenges.
Skin injury triggers food allergy in mouse model

2 months ago | derm.city | John Evans

Findings from a new study suggest skin injuries may contribute to the development of food allergies. The study authors say this finding may help explain why the prevalence of childhood food allergy is higher in individuals with eczema. The study, published in Science Immunology, was led by researchers at the Yale School of Medicine (YSM) in New Haven, Conn.
Sweetener molecule suppresses hair follicles in lab test

2 months ago | derm.city | John Evans

New research published in the British Journal of Dermatologyhas found that applying a common food additive to hair follicles can activate taste receptors and prevent hair growth in lab tests. While taste receptors are usually associated with tastebuds in the mouth, they are found throughout the body and perform various functions. Although taste receptors have previously been found in the skin, their function is unknown.
