As the weather warms up and we spend more time outdoors, it’s important to remember the importance of sun protection for healthy skin. Sun exposure can cause a variety of skin damage, from sunburns to premature aging to an increased risk of skin cancer. In this blog, we’ll explore why sun protection is so important, how to choose the right sunscreen, and other ways to protect your skin from the harmful effects of the sun.

Why Sun Protection is Important

Sun exposure can cause a variety of skin damage, including:

  1. Sunburn: When you get a sunburn, your skin is actually being damaged by the sun’s UV rays. This damage can cause redness, pain, and peeling.
  2. Premature aging: Sun exposure can also cause premature aging, including wrinkles, fine lines, and age spots. This is because UV rays can break down the collagen and elastin in your skin, which are responsible for keeping your skin firm and elastic.
  3. Skin cancer: Exposure to UV rays is the most common cause of skin cancer, which is the most common type of cancer in the United States. By protecting your skin from the sun, you can reduce your risk of developing skin cancer.

Choosing the Right Sunscreen

To protect your skin from the harmful effects of the sun, it’s important to choose the right sunscreen. Here are some factors to consider:

  1. SPF: The SPF, or sun protection factor, measures how well a sunscreen protects against UVB rays, which are the rays that cause sunburns. For best protection, choose a sunscreen with an SPF of 30 or higher.
  2. Broad-spectrum: Look for a sunscreen that is labeled “broad-spectrum,” which means it protects against both UVA and UVB rays. UVA rays are the rays that cause premature aging and skin cancer.
  3. Water-resistant: If you’ll be swimming or sweating, choose a water-resistant sunscreen that will stay on your skin even when it gets wet.
  4. Mineral vs. chemical: There are two types of sunscreens: mineral and chemical. Mineral sunscreens use physical blockers like zinc oxide and titanium dioxide to reflect the sun’s rays, while chemical sunscreens use chemicals like avobenzone and oxybenzone to absorb the sun’s rays. If you have sensitive skin or are concerned about the environmental impact of chemical sunscreens, choose a mineral sunscreen.

Other Ways to Protect Your Skin from the Sun

In addition to wearing sunscreen, there are other ways to protect your skin from the harmful effects of the sun:

  1. Wear protective clothing: When possible, wear long-sleeved shirts, pants, and hats to protect your skin from the sun.
  2. Seek shade: When the sun is strongest, typically between 10 a.m. and 4 p.m., seek shade under a tree or umbrella.
  3. Avoid tanning beds: Tanning beds use UV rays to darken your skin, which can cause the same damage as the sun.
  4. Check your skin regularly: Regularly checking your skin for new moles, freckles, or other changes can help you catch skin cancer early, when it’s most treatable.


Protecting your skin from the harmful effects of the sun is essential for healthy skin. By wearing sunscreen, choosing protective clothing, and seeking shade, you can reduce your risk of sunburns, premature aging, and skin cancer. If you’re concerned about the appearance of your skin, there are a variety of treatments available, from chemical peels to laser therapy to microneedling. Talk to your dermatologist about which treatment options are right for you.
