It's no surprise that everyone is now aware of the extent of pollution and its negative effects on human health. Urban residents are exposed to various types of pollution, including air, water, noise, and food. The most prominent reasons are automobiles, plastic, urbanization, and industrialization. All of these causes have exacerbated the rate of environmental contamination, which is now a major concern for both human health and the environment. The Air Quality Indicator alone is frightening to observe. Delhi AQI has entered the danger zone, which is a strong indication of its repercussions.
Pollution affects the entire body, whether it is in the form of air, water, or sound. The skin, as the largest and most exposed organ in the body, absorbs the majority of environmental contaminants. Air pollution is the quickest to affect the body, particularly the skin. Pollution has far-reaching impacts on the skin, causing everything from premature ageing to major skin problems including acne, eczema, and pigmentation. Don't worry; there is good news in the midst. One can save themselves by understanding the impact of pollution and how to limit its impacts.
Types of air pollutants
Pollution comes in many forms, including particulate matter (PM), chemicals like nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), volatile organic compounds (VOCs), and carbon monoxide (CO), which all contribute to the deterioration of skin health. The skin is a barrier that protects the body from environmental threats, but exposure to pollution can lead to its breakdown. The main pollutants that affect skin health are:
Particulate matter (PM2.5). These tiny particles, which are smaller than 2.5 micrometers, can penetrate the skin deeply, causing inflammation and oxidative stress. Due to their size, they are able to enter the pores, causing damage to the skin's natural barrier, leading to conditions like acne, irritation, and even chronic diseases like eczema.
Ultraviolet (UV) radiation and ozone. Ozone at ground level, often formed as a result of the interaction between UV rays and air pollutants, can be harmful to the skin. UV radiation and ozone exposure increase the formation of free radicals in the skin, which can lead to skin aging, DNA damage, and even skin cancer by constant exposure for long tenure. Combined with the effects of pollution, this can accelerate the process of skin aging.
Toxic gases (CO, NO2, SO2). Pollution from exhaust gases, especially in urban areas, contains carbon monoxide and nitrogen dioxide, which can increase the production of free radicals. These free radicals damage collagen and elastin in the skin, leading to loss of firmness and elasticity, and contributing to premature wrinkles.
Volatile organic compounds (VOCs). VOCs are chemicals found in solvents, paints, and cleaning products. When they mix with other pollutants, they can trigger inflammatory responses in the skin, leading to skin irritation, rashes, and allergic reactions. Additionally, VOCs can contribute to the breakdown of the skin’s protective barrier, leading to dehydration and sensitivity.
Heavy metals (Lead, Arsenic, Mercury). Exposure to heavy metals, often found in polluted air, can lead to skin pigmentation, dryness, and even an increased risk of skin cancer. These metals can build up in the skin, causing long-term damage.
Possible skin troubles due to pollution
Premature aging (Photoaging)
Exposure to pollution, particularly UV rays, accelerates the breakdown of collagen, a protein responsible for keeping the skin firm and elastic. This leads to the appearance of wrinkles, fine lines, and sagging skin. Over time, the skin may also develop age spots or hyper-pigmentation.
Acne
Pollution particles can clog the pores, leading to an increase in the secretion of sebum (natural skin oils). This creates an environment where bacteria thrive, causing inflammation and leading to acne breakouts. People who live in polluted environments may find that acne becomes more persistent and harder to treat.
Hyper-pigmentation
Pollution can lead to the production of melanin in excess, resulting in dark spots or hyper-pigmentation. These spots often appear on areas of the skin that are exposed to pollution, such as the face and hands.
Dehydration and sensitivity
Pollutants weaken the skin’s natural moisture barrier, leading to dryness, irritation, and sensitivity. The skin becomes more vulnerable to external irritants, making it more prone to conditions such as contact dermatitis.
Eczema and psoriasis
Industrial pollutants can trigger flare-ups of conditions like eczema and psoriasis, which cause red, itchy, and inflamed skin. The inflammatory response caused by pollution can exacerbate these chronic conditions, leading to more frequent flare-ups and worsening symptoms.
Skin cancer
Long-term exposure to air pollution, particularly ultraviolet radiation, increases the risk of skin cancer. The free radicals produced by pollution damage DNA in skin cells, which can eventually lead to mutations and the development of cancerous growths, such as basal cell carcinoma and melanoma.
Solutions to combat the effects of pollution on skin
While it is nearly impossible to completely avoid pollution, there are several ways to minimize its impact on the skin. A combination of skincare routines, lifestyle changes, precautions when outdoors and environmental modifications around home and office can help keep the skin and overall health protected despite exposure to pollutants.
Cleansing and removing pollutants. The first line of defense against pollution is proper cleansing. The skin should be washed thoroughly twice a day to remove dirt, toxins, and pollutants that accumulate on the skin. A gentle cleanser that removes pollutants without stripping the skin’s natural oils is recommended. There are many skin cleansing products available, check the ingredients and go for mild ones free from chemicals.
Antioxidant-rich skincare. Antioxidants like vitamins C and E, green tea extract, and niacinamide can help neutralize the free radicals generated by pollution. Regular use of serums or moisturizers with these ingredients can prevent premature aging and maintain the skin’s health. Along with topical application, intake of antioxidants like Vitamin C, and Glutathione is necessary.
Sun protection. Sunscreen is crucial in protecting the skin from UV damage. A broad-spectrum sunscreen with an SPF of at least 30 should be applied every day, even on cloudy days or indoors. In addition to protecting the skin from UV radiation, sunscreen also forms a barrier against pollutants. Some sunscreens also contain antioxidants to provide extra protection against pollution.
Don’t miss mask. Post-pandemic, people left wearing masks, but it is still necessary to wear them to protect facial skin and lungs. Every time you are outdoors, you must wear a good-quality mask.
Hydration. Pollution can lead to dehydration of the skin, so keeping the skin well-hydrated is essential. Using moisturisers with ingredients like hyaluronic acid, glycerin, and ceramides can help to lock in moisture and restore the skin's barrier function. Drinking plenty of water throughout the day is also important to maintain hydration levels and helps detoxification. Tuskca effervescent tablets are therefore favourite of many, along with nutritional benefits they add to hydration.
Air purification. One of the most effective ways to reduce pollution exposure is by purifying the air. Using air purifiers in your home, especially in areas with high pollution, can help to reduce indoor air contaminants. Additionally, plants like peace lilies and snake plants can help absorb indoor pollutants and improve air quality. Snake plants clean the air during the day, but release the most oxygen at night, making them an excellent addition to any bedroom.
Diets. Eating foods rich in antioxidants and anti-inflammatory properties can help fight the effects of pollution on the skin. Fruits and vegetables like berries, tomatoes, and spinach, as well as foods rich in omega-3 fatty acids like fish and nuts, can help boost skin health and combat inflammation caused by pollutants.
Avoidance of polluted areas. Whenever possible, avoid spending long periods of time in highly polluted areas. If you live in a city with high levels of air pollution, try to stay indoors during peak pollution times, especially in the mornings and evenings when pollution levels are typically higher.
Regular exfoliation. Regular exfoliation helps remove dead skin cells and pollutants that have built up on the surface of the skin. This promotes a healthy glow and prevents clogged pores. However, over-exfoliation should be avoided as it can irritate the skin, especially in polluted environments.
Understanding these risks is crucial for taking proactive steps to protect the skin. While it may be impossible to avoid pollution completely, adopting a comprehensive skincare routine, using protective products, and making lifestyle changes can significantly mitigate its harmful effects. As a responsible being, everybody should also try at their end to not contribute to environmental pollution or degradation. By avoiding plastic use, less plastic pollution, travelling by public transport or minimum four wheeler use, controlling water usage, no bursting crackers, and with such responsible acts even by a single person is effective.
