Your question is — which sunscreens are physical?

Physical sunscreens contain mineral ingredients such as zinc oxide or titanium dioxide, which reflect and scatter UV rays away from the skin.

For those who require additional information

Physical sunscreens contain mineral ingredients such as zinc oxide or titanium dioxide, which reflect and scatter UV rays away from the skin. These nanoparticles sit on top of the skin and act as a barrier against the sun’s harmful rays. Physical sunscreens are often preferred over chemical sunscreens because they provide immediate protection upon application and are less likely to cause skin irritation.

According to Dr. Dhaval Bhanusali, a board-certified dermatologist, “Physical sunscreens tend to be better for sensitive and acne-prone skin types due to the ingredients used. Chemical sunscreens, on the other hand, are better suited for darker skin tones due to their invisible nature.”

Here is a list of interesting facts about physical sunscreens:

  • Physical sunscreens were first developed in the 1930s but were popularized in the 1980s.
  • Zinc oxide has been used since ancient times as a skin protectant.
  • Titanium dioxide is also widely used in cosmetics and skincare products for its ability to reflect light and provide a matte finish.
  • Physical sunscreens can be water-resistant, making them a popular choice for outdoor activities and sports.
  • The thickness and color of physical sunscreens may vary depending on the concentration of mineral ingredients.

Here is a table comparing physical and chemical sunscreens:

Physical Sunscreens Chemical Sunscreens
Active ingredients Zinc oxide and/or titanium dioxide Avobenzone, oxybenzone, octinoxate, octisalate, and more
Protection Reflects and scatters UV rays Absorbs UV rays
Immediate Yes No (must be applied 20-30 minutes before sun exposure)
Skin types Sensitive, acne-prone Darker skin tones
Texture Thick, white Thin, clear
Residue May leave white cast on skin May leave greasy residue on skin
Environmental Reef-safe (does not contribute to coral bleaching) May contain ingredients harmful to coral reefs

In summary, physical sunscreens contain mineral ingredients such as zinc oxide or titanium dioxide and are an effective way to protect the skin from harmful UV rays. They are a good choice for those with sensitive or acne-prone skin and are often preferred over chemical sunscreens.

Dermatologist Weilan Johnson compares physical and chemical sunscreens, explaining that the former creates a barrier that reflects UV light, while the latter absorbs UV light and can release heat. While chemical sunscreens have better transparency and absorption, they may prove to be irritating for sensitive skin types or those prone to redness or rosacea. Physical sunscreens are thus recommended for babies and those experiencing skin sensitivity issues. Interested buyers can visit to determine their preferred sunscreen type.

Additional responses to your query

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.

Interesting facts about the subject

Fact: Of the chemicals in the sunscreens tested for, oxybenzone was found to be absorbed within 30 minutes and reached the highest levels in blood. Oxybenzone, also listed as benzophenone-3 on labels, is a chemical that absorbs light and protects the skin from the harmful effects of UV radiation.
Fact: The American Academy of Dermatology found that just over 40 percent of Americans tend to only reapply sunscreen when they get wet, if at all. "Sunscreen should be reapplied every two hours, or immediately after heavy sweating or swimming," Zeichner said.
