Basic principles of anti-pollution skin care products
1. Physical Barrier
Anti-pollution skin care products create a physical barrier on the skin to prevent external pollutants from directly contacting it. These products often contain silicone or mineral ingredients, such as zinc oxide or titanium dioxide, which form a protective film on the skin’s surface, effectively isolating dust, particles, and other pollutants.
2. Cleansing Action
Many anti-pollution formulations include cleansing agents that deeply cleanse the skin, removing pollutants and excess oils that may accumulate on the skin’s surface. Ingredients such as salicylic acid and alpha hydroxy acids (AHAs) help prevent clogged pores and reduce the risk of skin issues.
3. Antioxidant Protection
Anti-pollution skin care products typically contain antioxidant ingredients, such as vitamin C, vitamin E, and green tea extract, that neutralize the damage caused by free radicals. Pollutants can generate a significant amount of free radicals, leading to oxidative stress on the skin, which increases the risk of aging and damage. Antioxidant ingredients help protect skin cells and slow down the aging process.
4. Hydration and Repair
These products are often rich in moisturizing ingredients, such as hyaluronic acid and glycerin, which help maintain the skin’s moisture balance and enhance its barrier function. Additionally, some repairing ingredients (like ceramides and centella asiatica extract) can promote skin healing and alleviate irritation and redness caused by pollution.
5. Promoting Skin Self-Repair
Some anti-pollution products also contain ingredients that promote the skin’s self-repair, such as peptides and plant extracts. These components can stimulate collagen production, improving the skin’s resilience and elasticity, thereby enhancing its ability to withstand external pollution.
Commonly used active ingredients in anti-pollution skin care products
