Zinc oxide doesn’t show any association with skin damage.

In newspapers

Zinc oxide (ZO) is one of the vital effective ingredients in sunscreen, but previous studies have suggested that it may well potentially damage skin cells. Now, slightly study within the February 2019 Journal Investigative Dermatology have found that ZO nanoparticles don't penetrate the skin or damage the skin on the cellular level even after repeated application.

ZO is one in all 17 energetic sunscreen ingredients approved by the FDA. ZO offers broad-spectrum protection and shields against UVB rays, which cause sunburn, and UVA rays, which penetrate deeper and damage cell DNA and increase the danger of skin cancer. are

In the study, researchers applied 1/4 teaspoon of ZO sunscreen to people's arms over five days — once every hour for six hours on one arm and once on the opposite arm. Next, they used fluorescence imaging technology to look at the skin. They found that ZO nanoparticles stay inside the epidermis (top) layer of the skin and don't penetrate deeper into the skin. Nor was there any sign of cellular toxicity.

Researchers recommend that folks not avoid using ZO sunscreen, especially because it is an efficient strategy to prevent sunburn and protect against skin cancer.
