Summer is here and it's a great time to review: Tips for Protecting Your Skin

Sunscreen is an essential component of any skincare routine. It helps protect the skin from the harmful effects of the sun, such as premature aging and skin cancer. Unfortunately, many people do not use sunscreen regularly or they may not use it correctly. In this article we will discuss the importance of sunscreen and provide tips for using it effectively.

Why is Sunscreen Important?

The sun emits harmful ultraviolet (UV) radiation that can damage the skin. This damage can manifest in various ways, such as sunburn, skin aging and skin cancer.

Sunburn is a common form of skin damage that occurs when the skin is exposed to too much UV radiation. It can cause redness, pain and peeling. It increases the risk of developing skin cancer.

Skin aging is another form of damage caused by UV radiation. The sun can cause wrinkles, fine lines and age spots to appear. These signs of aging can make you look older and can be challenging to treat.

Skin cancer is the most severe consequence of sun damage. It is the most common type of cancer in the United States and it can be deadly. According to the American Cancer Society, approximately 100,000 new cases of melanoma (the deadliest form of skin cancer) are diagnosed each year.

Tips for Using Sunscreen Effectively

To get the most benefit from sunscreen, it is essential to use it correctly. Here are some tips for using sunscreen effectively:

  1. Choose a broad-spectrum sunscreen: Look for a sunscreen that offers broad-spectrum protection. This means it protects against both UVA and UVB rays.
  2. Use enough sunscreen: The American Academy of Dermatology recommends using enough sunscreen to fill a shot glass (about one ounce) for the entire body. For the face and neck, use about a nickel-sized amount.
  3. Apply sunscreen before going outside: Apply sunscreen 15-30 minutes before going outside to allow it to absorb fully into the skin.
  4. Reapply sunscreen every two hours: Reapply sunscreen every two hours, or more frequently if you are swimming or sweating.
  5. Wear protective clothing: Sunscreen is not enough to protect your skin from the sun's harmful rays. Wear protective clothing such as a large brimmed hat and long-sleeved shirt when you are outside.
  6. Seek shade: When possible, seek shade during the sun's peak hours (10 am to 4 pm).
  7. Don't forget to protect your lips: Use a lip balm with SPF to protect your lips from the sun's harmful rays.

How to Choose the right SPF

When choosing a sunscreen, it is important to consider the SPF or Sun Protection Factor. The SPF indicates how much protection the sunscreen provides against UVB radiation, which is the primary cause of sunburn and skin cancer. I recommend using a sunscreen with an SPF of at least 30, as this can block up to 97% of UVB rays.

Higher SPF values do not necessarily mean better protection, as they only offer a marginal increase in protection beyond SPF 50. It is also important to choose a sunscreen that offers broad-spectrum protection, meaning it protects against both UVA and UVB rays.
