Sunscreen is considered a sensitive topic that should be approached with caution. However, it is a fact that certain compounds found in commercial products can cross the blood-brain barrier and affect our neurons. Some of these compounds, which are abundant in certain sunscreens and cosmetics, have been linked to neurodegenerative conditions. These compounds are small molecules that have the ability to enter neurons, causing damage.

Zinc

Zinc-based sunscreen provides effective and safe sun protection that is gentle on the skin and the environment.

  • Broad-spectrum protection

    Zinc oxide provides broad-spectrum protection against both UVA and UVB rays. This means it protects your skin from both the immediate damage caused by UVB rays (sunburn) and the long-term damage caused by UVA rays (premature aging, skin cancer).

  • Physical barrier

    Zinc oxide creates a physical barrier on the skin that reflects and scatters UV rays away from the skin. This is different from chemical sunscreens that absorb UV rays and convert them into heat, which can cause irritation or allergic reactions.

  • Safe and gentle

    Zinc oxide is a safe and gentle ingredient that is unlikely to cause skin irritation or allergic reactions. It is also non-comedogenic, which means it does not clog pores or contribute to acne.

  • Environmentally friendly

    1. Zinc oxide is not harmful to the environment, unlike some chemical sunscreen ingredients that can harm marine life and damage coral reefs.

    Overall, zinc-based sunscreen provides effective and safe sun protection that is gentle on the skin and the environment.

How it works

Zinc-based sunscreen works by creating a physical barrier on the skin that reflects and scatters UV radiation away from the skin. Zinc oxide is the active ingredient in zinc-based sunscreen that provides this protection. It is a mineral that sits on the skin's surface and reflects UV radiation like a mirror.

SPF Indication

The SPF (Sun Protection Factor) indication on sunscreen refers to the level of protection it provides against UVB rays, which are the rays that cause sunburn and contribute to the development of skin cancer.

SPF is a measure of the amount of UVB radiation that is required to cause sunburn on protected skin compared to unprotected skin. For example, an SPF 30 sunscreen will provide 30 times the protection against UVB rays than no sunscreen at all.

2 minutes of casual sun a day at the end of one year = 2 full weeks of sunbathing.
