How to protect your skin from pollution every day

We often think about protecting our skin from the sun, but less often from pollution. Yet, whether in the city or indoors, our skin is exposed daily to a mix of fine particles, ozone, and chemical compounds that constantly put a strain on it. This is what scientists refer to as the “exposome”—the totality of environmental stressors that affect the skin throughout a person’s life.

When it comes to pollution, the most effective strategy is based on two simple steps: thoroughly cleansing the skin and boosting its antioxidant defenses. Here's how to protect your skin every day—it's that simple.

Pollution: An Invisible Threat to the Skin

Air pollution consists primarily of fine particulate matter, the smallest of which can settle on the skin and carry chemical compounds such as polycyclic aromatic hydrocarbons. Ozone and other pollutants are also present. When they come into contact with the skin, these substances promote the production of free radicals—unstable molecules responsible for oxidative stress.

The problem is that the skin has limited antioxidant reserves. It has been shown that exposure to ozone, for example, depletes the vitamins C and E naturally present in the epidermis and promotes lipid oxidation. When these defenses are overwhelmed, oxidative stress sets in and begins to damage the skin.

The Effects on the Skin

The effects of pollution are subtle at first, but become increasingly noticeable over time. In the short term, the skin barrier can be compromised, leading to discomfort, dehydration, and a dull complexion. Pollution is also associated with low-grade inflammation and the appearance of dark spots.

In the longer term, this repeated oxidative stress contributes to premature skin aging by accelerating collagen breakdown and the appearance of wrinkles. That is why protecting your skin from pollution is an essential part of a preventive skincare routine.

Cleaning: The First Line of Defense

The first step in combating pollution is thorough cleansing—especially in the evening—to remove particles and impurities that have built up throughout the day. A double cleanse is particularly effective here. The PERS Cleansing Duo, consisting of the Radiance Makeup Remover Balm and the Soothing Cleansing Gel, first dissolves makeup and oily impurities, then removes any remaining residue.

Both of these treatments contain a 3% targeted anti-pollution agent as well as a complex of vitamins C and E. So they don’t just purify the skin without irritating it: they also help it defend itself against oxidative stress, while preparing it to receive subsequent skincare products.

Boost antioxidant defenses

Since pollution depletes the skin’s antioxidants, it makes sense to replenish them through external sources. Vitamin C is an ideal active ingredient here: recent studies have shown that it protects the skin against damage caused by pollution particles, and that a vitamin C complex helps preserve the skin barrier when exposed to multiple pollutants.

When applied in the morning, the 10% PERS Vitamin C Serum strengthens the skin’s antioxidant defenses and helps neutralize free radicals, while restoring the complexion’s radiance. It acts as an internal shield that complements your cleansing routine.

Everyday Actions to Combat Pollution

• Cleanse thoroughly in the evening—ideally using a double cleansing routine—to remove particles and impurities.
• Apply an antioxidant serum in the morning—such as a vitamin C serum—to strengthen the skin's defenses.
• Use sunscreen, as pollution and UV rays often work together to increase oxidative stress.
• Support the skin barrier with appropriate moisturizers to help it become more resilient.
• Avoid over-cleansing the skin, as overly aggressive cleansing weakens the skin barrier instead of protecting it.

Key Takeaways

Pollution is a daily, invisible threat that overwhelms the skin’s antioxidant defenses, weakens its barrier, and contributes to premature aging. The good news is that you can combat this with simple steps: thoroughly cleanse your skin in the evening to remove particles, and boost its antioxidant defenses in the morning, particularly with vitamin C. Protecting your skin from pollution is, above all, a matter of consistency—day after day.
