Climate change is not merely an environmental issue — it is also a serious public health matter. In the field of dermatology, we have been observing in recent years that skin conditions previously considered rare are increasing in frequency due to climate change. By 2026, this connection has become too pronounced to ignore.
Rising UV Radiation and Skin Cancer Risk
The intensity of UV radiation reaching the Earth's surface is increasing due to ozone layer thinning and atmospheric changes. UV index values in the Mediterranean and Aegean regions have risen considerably over the past decade. This is directly associated with the increase in skin cancer cases, including melanoma.
The periods of heightened sunburn risk have extended, and seasonal sun protection habits have proved insufficient. We now emphasise to our patients that high-level sun protection is required not only in summer but also during spring and autumn.
Rising Temperatures and Skin Infections
Global temperature increases are expanding the geographic distribution of fungal and bacterial infections. Some dermatoses previously confined to tropical regions are now being observed in temperate climates. Hot and humid conditions increase the prevalence of dermatophyte infections, candidiasis, and bacterial folliculitis.
During extreme heat waves, we are recording a marked rise in cases of miliaria (heat rash), sweat-triggered eczema flares, and contact dermatitis. Elderly individuals and those with chronic skin conditions are disproportionately affected by these impacts.
Shifting Allergen Profiles
Climate change is extending the pollen season and altering the geographic distribution of allergenic plants. Longer and more intense pollen seasons are leading to increases in allergic contact dermatitis and atopic dermatitis flares. In 2026, a notable rise in allergic skin reactions is being observed across many regions compared to previous years.
Humidity Imbalances and the Skin Barrier
The increasing frequency of extreme weather events, sudden humidity fluctuations, and prolonged drought periods are straining the skin barrier's capacity to adapt. Low humidity levels increase transepidermal water loss, while excessively humid environments create conditions that promote microbial proliferation. These imbalances contribute to triggering chronic dryness, skin sensitivity, and inflammatory skin diseases.
New Approaches in Dermatology
Adaptive Skincare Protocols: Dynamic care routines that adapt to seasonal and climatic changes are now an integral part of our standard treatment plans. We develop personalised regimens based on the micro-climate conditions of the region where the patient lives.
Enhanced Sun Protection Strategies: Year-round broad-spectrum sunscreen use, protective clothing recommendations, and smart technologies that track UV exposure are coming to the fore.
Barrier Support Therapies: Dermocosmetics containing prebiotic and postbiotic ingredients support the skin microbiome, increasing resilience against changing environmental conditions.
Early Screening Programmes: Due to increasing skin cancer risk, we emphasise the need to expand both the frequency and scope of dermoscopic screening.
Conclusion
Climate change is driving a paradigm shift in dermatology. We must adapt both our preventive and therapeutic approaches to this new reality. If you notice unusual changes in your skin, we recommend scheduling a professional dermatological assessment without delay. Please contact us to book a consultation.
