Is sunscreen with zinc oxide better? Are Zinc Oxide Sunscreens Better?
Zinc oxide is a stable sunscreen ingredient that is much less likely than chemical ingredients to break down in the bottle or on your skin. Zinc oxide does not irritate sensitive skin. Zinc oxide is not absorbed into your body; it stays on your skin where you put it and where it can protect you from the sun.
Why do dermatologists recommend zinc sunscreen?
Zinc oxide sunscreens are mineral based, which means they form a skin barrier that reflects UV rays. Zinc sunscreens are less likely to cause skin irritation or allergic reactions, making them a better option if you have sensitive skin.
Is zinc oxide in sunscreen safe?
We know that zinc oxide often serves as the active ingredient in SPF-containing cosmetic products and sunscreens designed to help minimize the damaging impact of sun exposure. We know the current literature does not show any adverse health outcomes from nano-sized zinc oxide particles found in cosmetics or sunscreens.
Why Do Sunscreens Give White Cast? As mentioned earlier, sunscreens are designed to protect your skin from radical photodamage. Since most sunscreens contain titanium dioxide and zinc oxide, which remain on the skin's surface rather than being absorbed, they tend to leave a white cast, leading to an ashy look.
Is zinc oxide sunscreen safe?
Zinc oxide is the second GRASE sunscreen ingredient, allowed in concentrations up to 25 percent. Studies show it's safe, with no evidence of skin penetration, even after repeated use.

What is a physical sunscreen?
Physical sunscreens, also commonly called mineral sunscreens, sit atop the skin rather than absorbing into it. They create a barrier on the skin's surface that reflects UV rays to prevent damage and sunburns. There are currently only two FDA approved physical ingredients: titanium dioxide and zinc oxide.
