Climate change, a global phenomenon characterized by rising temperatures, changing weather patterns, and increased UV radiation, has profound consequences for human health, particularly the skin. Leading experts in cosmetology and dermatology provide their insights into how climate change affects our skin and how to combat these challenges.
Fluctuations in Humidity and Skin Hydration
Dr. Madhu Chopra, MBBS, DORL, Cosmetologist, and Managing Director of Studio Aesthetique in Mumbai, emphasizes the significant impact of fluctuating humidity levels on skin hydration. “Low humidity can lead to dry, cracked skin, worsening conditions such as dermatitis and psoriasis,” Dr. Chopra explains. “Conversely, high humidity can promote the growth of bacteria and fungi on the skin, increasing the risk of infection.” This duality makes maintaining optimal skin hydration challenging as individuals are exposed to varying levels of humidity, underscoring the importance of adapting skincare routines to changing environmental conditions.
Climate change often brings increased air pollution, with higher levels of pollutants such as particulate matter (PM), nitrogen dioxide (NO2), and ground-level ozone (O3). “These pollutants can penetrate the skin barrier, leading to oxidative stress and inflammation,” Dr. Chopra notes. “Oxidative stress damages skin cells and depletes antioxidants, which are key to skin renewal and defense, leading to premature aging, pigmentation disorders, and an increased risk of allergic skin reactions.”
To protect your skin from the effects of climate change, Dr. Chopra recommends using a broad-spectrum sunscreen daily, wearing protective clothing, and seeking shade. “Keep your skin hydrated with moisturizers, stay hydrated by drinking water, and cleanse gently to remove pollutants,” she advises. “A non-alcoholic toner is a must after cleansing. Apply serum preferably with hyaluronic acid and vitamin C, and lastly, a good sunscreen with SPF 30-50. Eat a healthy diet rich in antioxidants to fight oxidative stress and promote skin renewal.”
The Indian Context
Dr. Debeshi Bhattacharjee, MBBS, DALM, FAAM, an award-winning clinical cosmetologist and founder of Lueur Aesthetics, highlights the specific challenges faced in India. “Increased UV radiation due to ozone layer depletion accelerates aging, causing wrinkles, pigmentation, and a higher risk of skin cancer,” she explains. Rising temperatures and humidity levels exacerbate conditions like acne and eczema, as heat and sweat can clog pores and trigger breakouts, while humidity increases oil production.
Air pollution in many Indian cities contributes to oxidative stress, leading to premature aging, inflammation, and a compromised skin barrier. “Harmful particles from pollution penetrate the skin, causing cellular damage,” Dr. Bhattacharjee states. “Extreme weather conditions, such as intense heatwaves and cold spells, further disrupt the skin barrier, causing dryness and sensitivity. Additionally, increased pollen levels can trigger allergic reactions, leading to rashes and hives.”
Dr Bhattacharjee emphasizes the importance of a comprehensive skincare routine to protect the skin. “Including antioxidants, moisturizers, and broad-spectrum sunscreen in your routine is essential. Consulting with a dermatologist can help tailor a skincare regimen to combat these environmental stressors and maintain healthy skin amidst the changing climate in India.”
Increased UV Exposure and Skin Cancer Risks
Dr. Trishna Gupte, a clinical cosmetologist and trichologist, international trainer, and founder, The Cosmo-Square clinic, ISCA, discusses the increased exposure to UV radiation due to climate change. “This increased exposure significantly raises the risk of skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma,” Dr. Gupte warns. “Increased UV radiation accelerates skin aging, causing wrinkles, fine lines, and pigmentation. The longer we are exposed to the sun, the weaker our antioxidant defenses become. These protective substances are intended to protect the skin from these harmful sources of radiation.”
Higher temperatures caused by climate change can also worsen the sweating functions of our skin, leading to heatstroke if prolonged exposure occurs without interruption from the sun’s rays. Dr. Gupte stresses the importance of using broad-spectrum sunscreens, wearing protective clothing, and avoiding excessive sun exposure to mitigate these effects.
As climate change continues to impact our environment, its effects on our skin are becoming increasingly evident. Experts like Dr. Madhu Chopra, Dr. Debeshi Bhattacharjee, and Dr. Trishna Gupte highlight the importance of adapting our skincare routines to these changing conditions. By staying informed and proactive, we can better protect our skin from the harmful effects of climate change.
