Living in the city, working long hours in front of a screen, and moving daily in environments full of smog and artificial light exposes the skin to a type of environmental stress that, until a few years ago, was considered secondary. Today, however, dermatological research has shown that air pollution and blue light are two factors that can significantly influence skin health. Fine dust, heavy metals, volatile organic compounds, and high-energy visible light radiation contribute to the formation of free radicals, alter the barrier function of the epidermis, and accelerate some mechanisms underlying skin aging.
The skin is, in fact, the organ most directly exposed to the external environment and, for this reason, is particularly vulnerable to the effects of urban pollution. Numerous studies have shown that atmospheric particulate matter (PM), especially that smaller than 2.5 microns, can deposit on the skin surface and promote oxidative stress.
Over time, these processes can contribute to the appearance of dyschromia, loss of elasticity, and premature aging. Furthermore, some dermatological conditions such as acne and atopic dermatitis can be exacerbated by the presence of environmental pollutants.
Added to this scenario is another typical element of contemporary life: prolonged exposure to blue light emitted by electronic devices such as smartphones, tablets, computers, and LED screens. Blue light belongs to the High Energy Visible (HEV) light band and is present in both sunlight and artificial sources. Several studies have shown that high doses of blue light exposure can induce the formation of reactive oxygen species (ROS), contributing to skin oxidative stress and phenomena of hyperpigmentation and photoaging. Some in vitro research has also observed that blue light exposure can reduce cell viability and increase free radical production in keratinocytes.
In this context, daily skincare plays a fundamental role not only in keeping the skin hydrated but also in protecting it from the environmental stresses to which it is exposed every day.
Cleansing: the first anti-pollution step
The first step to counter the impact of pollution on the skin is proper cleansing. During the day, smog, fine dust, and environmental residues tend to deposit on the skin surface, adhering to the stratum corneum. If not effectively removed, they can promote oxidative stress and alter the skin's barrier function. For this reason, cleansing should be done morning and evening using gentle but effective products capable of eliminating impurities and residues without compromising the skin's physiological balance. A correct routine involves using non-aggressive cleansers, such as a cleansing milk possibly followed by micellar water, to completely remove particles deposited on the skin surface.
Lifestyle and skin protection
Lifestyle also plays an important role in maintaining skin health. A balanced diet rich in fruits and vegetables, proper hydration, and regular physical activity contribute to the general well-being of the body and skin. Avoiding smoking and alcohol abuse also helps reduce further sources of oxidative stress. However, when living in urban environments, sometimes these good habits alone are not enough to completely neutralize daily exposure to environmental agents. For this reason, modern cosmetology has begun to develop specific formulations capable of helping to protect the skin from the effects of smog and blue light.
Anti-pollution skincare: how it works
A cosmetic designed to support the skin in case of pollution should contain active ingredients with antioxidant and protective properties, capable of counteracting the formation of free radicals and supporting the epidermal barrier function. Among the most interesting ingredients in this area are peptides extracted from moringa seeds. These molecules are known for their ability to limit the adhesion of polluting particles to the skin surface and contribute to skin purification. The action is twofold: on the one hand, they reduce the accumulation of particulate matter on the skin, and on the other hand, they help to counteract the oxidative stress induced by smog, heavy metals, and fine dust. Alongside this protective action, it is essential to support the integrity of the skin barrier. Ingredients such as phospholipids and glucosamine contribute to improving skin compactness, helping the skin to better defend itself against external agents.
Blue light and oxidative stress
In recent years, cosmetic research has also focused on the effects of blue light on the skin. Although the amount emitted by electronic devices is less than that from the sun, daily and prolonged exposure can contribute to oxidative stress. Experimental studies have shown that exposure to blue light can increase the production of free radicals in skin cells and reduce cell viability. Some plant-derived antioxidant molecules have proven particularly interesting in counteracting these effects. Among these, olive polyphenols, such as hydroxytyrosol and tyrosol, stand out for their powerful antioxidant activity. These compounds can also be obtained from the vegetable waters resulting from olive processing, a byproduct of olive oil production that represents a precious source of polyphenols. Through recovery and purification processes of washing waters, these molecules can be extracted and used in cosmetics, contributing to more sustainable production models in an anti-waste perspective.
The answer from cosmetological research: DERMAGENIA Daylife Regenerating Cream
To respond to the new needs of skin exposed to urban life, SKINIUS has developed DERMAGENIA Daylife Regenerating Cream, a daily shield designed to protect the skin during daytime and active life, when it is most exposed to indoor and outdoor environmental pollutants and blue light emitted by screens. The formula combines different protective approaches. Peptides extracted from moringa seeds help limit the adhesion of polluting particles to the skin surface and create an invisible protective film that helps defend the skin from environmental agents, including cigarette smoke. Protection from oxidative stress induced by blue light is supported by olive vegetable water, a raw material obtained from the wastewater of cold-pressed olives from a Sicilian olive oil supply chain. From this process, hydroxytyrosol and tyrosol are obtained, two powerful polyphenols with antioxidant activity. The formula is completed by a pool of chrono-hydrating sugars, hydrolyzed yeast proteins, organic olive oil, and marjoram, ingredients that contribute to supporting skin hydration and well-being throughout the day.
In a context where the urban environment exposes the skin to multiple stress factors, skincare is no longer just an aesthetic gesture but becomes a tool to help protect the skin daily. Incorporating products formulated to counteract smog, blue light, and oxidative stress into your routine means helping the skin maintain balance, radiance, and comfort for longer. In the presence of skin conditions, it is always advisable to consult a dermatologist, while for choosing the most suitable products for your skin, the pharmacist is a valuable reference for receiving professional and personalized advice.
