Zinc oxide used in cosmetics is one of the most popular active ingredients, particularly in mineral sunscreens. This ingredient is highly stable and safe for sensitive skin. It even provides broad-spectrum protection against UVA and UVB rays.
Zinc Oxide Used in Cosmetics for Maximum Protection
Many people wonder how zinc oxide actually works to protect the skin, especially from the dangers of the sun. Here’s the explanation.
- Physical Method
Unlike some chemical sunscreens, which work by absorbing UV radiation and converting it into heat, zinc oxide is classified as a mineral sunscreen.
This means that zinc oxide creates a thin layer on the skin’s surface. Its function is to reflect and scatter UV radiation before it reaches deeper layers of the skin.
This is why zinc oxide used in cosmetics is often recommended for sensitive skin, even babies.
- Broad-Spectrum Protection
One of the advantages of zinc oxide is its ability to provide protection against two types of solar radiation. This includes UVB rays, the main cause of sunburn, redness, and DNA damage.
It can even trigger skin cancer. The particle structure of zinc oxide is highly effective in preventing UVB radiation from penetrating the skin.
Meanwhile, UVA rays can penetrate deeper into the skin and trigger various problems, ranging from premature aging, wrinkles, hyperpigmentation, and collagen damage.
Not many sunscreen ingredients can effectively block UVA. However, zinc oxide is one of the most effective ingredients in blocking both long- and short-wavelength UVA rays.
With this broad range of protection, zinc oxide is used in cosmetics as an ideal choice for sunscreen products, especially those that truly maintain skin health.
- Not Easily Degraded by Light
Some chemical sunscreen ingredients can experience photodegradation, or structural damage, especially with prolonged exposure to sunlight.
In contrast, zinc oxide has high photochemical stability. This ensures consistent protection, does not easily degrade or decrease in effectiveness, and is safe in the long term.
This is why many skincare manufacturers rely on zinc oxide for their long-lasting mineral sunscreen products.
- Protects Without Clogging Pores
Although it forms a physical layer, zinc oxide does not absorb excessively into pores. Therefore, it is suitable for oily, acne-prone, and sensitive skin. This ingredient works on the skin’s surface, reducing the risk of blackheads and irritation.
- Safe for Daily Use and the Environment
Besides its safety for the skin, zinc oxide is also considered more environmentally friendly. This is especially true when compared to certain chemical sunscreen ingredients that can negatively impact marine ecosystems. Non-nano zinc oxide is often chosen because it doesn’t damage coral reefs.
Zinc oxide used in cosmetics acts as a protective barrier that reflects and scatters UVA and UVB rays. With broad-spectrum protection, high stability, and a safe formula for all skin types, zinc oxide is worth considering. Using products containing zinc oxide daily is an important step in maintaining healthy, protected, and youthful skin.
