What is zinc oxide and titanium dioxide?

Zinc oxide and titanium dioxide are two naturally occurring minerals that sit on top of your skin to create a barrier and reflect the sun's powerful UVA and UVB rays. These minerals are the primary active ingredients in physical sunscreen, also known as mineral sunscreen.

Is zinc oxide and titanium dioxide Safe?

Mineral sunscreens are made with titanium dioxide and zinc oxide, usually in the form of nanoparticles. The FDA proposed that both titanium dioxide and zinc oxide be classified as safe and effective.

Should sunscreen have zinc oxide and titanium dioxide?

If you want to be sure you are using a chemical-free (a.k.a. physical/mineral) sunscreen, the active ingredients should have ONLY zinc oxide and/or titanium dioxide minerals listed.

What's better zinc oxide or titanium dioxide?

Zinc Oxide Sunscreens is Better

In conclusion, zinc oxide sunscreens have a slight edge over titanium dioxide. Titanium dioxide is effective at blocking UV-B and short-wave UV-A rays, but it is less effective than zinc dioxide at blocking long UV-A rays.

How do zinc oxide and titanium dioxide protect your skin?

Titanium dioxide and zinc oxide are two naturally occurring minerals. When applied topically, they have the ability to block the sun's UVA and UVB radiation from being absorbed into your skin, meaning they are considered broad-spectrum.

Analysis of Titanium Dioxide

What kind of sunscreen is best?

The American Academy of Dermatology (AAD) recommends wearing a broad-spectrum sunscreen with an SPF of 30 or higher every day. This protects against approximately 97% of the sun's UV rays.

What ingredient is best for sunscreen?

Sunscreen for skin problems or allergies.

Go for titanium dioxide or zinc oxide instead of chemicals like para-aminobenzoic acid (PABA), dioxybenzone, oxybenzone, or sulisobenzone. If you have skin irritation or allergies, avoid sunscreens with alcohol, fragrances, or preservatives.

Do you need both zinc oxide and titanium dioxide?

Do you want zinc oxide in sunscreen?

To improve a sunscreen's filtration of UVB and UVA and to raise its SPF rating, chemicals (usually octinoxate) must be added. Higher-SPF mineral sunscreens need to contain higher levels of zinc oxide (which is generally not cosmetically acceptable) or additional UV-filtering chemicals.

Is titanium dioxide harmful for skin?

In the study, the scientists from the University of South Australia's Future Industries Institute showed that titanium dioxide nanoparticles do not harm human skin cells and even protect cells against ultraviolet damage.

Is zinc oxide cancerous?

This in turn could increase the risk of skin cancer. Ma also found that the longer zinc oxide is exposed to sunlight, the greater the potential damage to human cells. "Zinc oxide may generate free radicals when exposed to UV (ultraviolet) sunlight," May says, "and those free radicals can kill cells."

Is titanium dioxide sunscreen bad for you?

Titanium Dioxide: This ingredient isn't a human-made chemical, but a naturally-occurring mineral found in the earth's crust. This UV filter can be safe in mineral sunscreen if it's used and processed under certain conditions.

Is zinc oxide safe?

Zinc oxide

The ingredient doesn't cause harm unless it's swallowed or inhaled. Compared to avobenzone and titanium oxide, it's cited as a photostable, effective, and safe for sensitive skin.

What percentage of zinc oxide and titanium dioxide should be in sunscreen?

How much zinc oxide should be in a mineral sunscreen? An effective mineral sunscreen will contain a zinc oxide and/or titanium dioxide concentration of at least 10 percent, but no higher than 25 percent.

Is titanium dioxide safe to use?

Foods with titanium dioxide are typically candies, pastries, chewing gum, coffee creamers, chocolates, and cake decorations. Although there are some safety concerns, the FDA generally recognizes titanium dioxide as safe. Moreover, most people do not consume nearly enough to cause any potential harm.

Does zinc oxide darken skin?

One drawback of zinc oxide is that in its raw form it's stark white and has a very thick consistency. That means that those with darker complexions might experience a cast when applying a sunscreen containing it, which can turn their skin a temporary greyish hue.

What is the benefit of zinc oxide in sunscreen?

Unlike chemical sunscreens which absorb into the skin, zinc oxide sunscreen sits on the surface, and deflects the sun's rays, providing instant protection against any sun damage. “Mineral or physical sunscreen works by laying on the surface of the skin and deflecting UV rays away from the skin.

Does the percentage of zinc oxide in sunscreen matter?

There is a misconception that more Zinc Oxide in a product will deliver higher level of UV protection and it just isn't true. It's not that simple. Percentage of Zinc Oxide in a product does not equate to higher or lower SPF or more or less UVA protection.
