Skin Care and Sunscreen by Jennifer Mead, LVN

Jennifer Mead, LVNDo you work outdoors?  Regardless of whether your job is outside or not, it is important to know how to properly protect yourself from the damaging rays of the sun.

What is sunscreen?  Sunscreen is a lotion, gel or spray that protects the skin from ultraviolet light. By absorbing or reflecting the sun’s ultraviolet light or radiation, sunscreen can protect the skin from sunburn.  The American Cancer Society recommends the use of sunscreen because it can aid in the prevention of squamous cell carcinoma, otherwise known as skin cancer.

Sunscreens are commonly labeled and rated with a sun protection factor (SPF). The SPF measures the sun-burning fraction of UV rays that reach the skin surface. For example, an “SPF 25” means that 1/25th of burning radiation from the sun reaches the skin through the thickness of the sunscreen. The American Academy of Dermatology recommends everyone use sunscreen that offers the following:

  • Broad-spectrum protection (protects against UVA and UVB rays)
  • Sun Protection Factor (SPF) 30 or higher
  • Water resistance

It is recommended that if you are going to be outside every day, you should protect yourself with sunscreen and this includes being outside when it is grey and overcast. Even on cloudy days, 80 percent of the sun’s UV rays can penetrate the skin. But how much do you use? You will want to apply enough to coat the skin that is not covered by clothing. The rule of thumb is enough sunscreen to fill a shot glass or 1 ounce. This amount is what dermatologists recommend to cover enough skin that is being exposed however you will want to adjust the amount according to your body size, and apply sunscreen 15 minutes before going outside as well as apply every 2 hours after swimming or sweating according to the directions on the bottle. It is good to remember that skin cancer can also form on the lips so you want to use a good chapstick or lipstick with an SPF of 30 or higher. There are many kinds of sunscreen on the market and which one to use is a matter of preference. Just make sure you choose a broad-spectrum UVA and UVB sunscreen that has an SPF of 30 or higher.

Sunscreen options come in a variety of lotions, creams, sprays, gels & sticks:

  • Face creams are best for dry skin.
  • Gels are preferable for hairy areas such as scalp or the male chest.
  • Sticks work best for around the eyes.

Although sprays are preferred by parents to use on children because they are easier to apply, make sure that you use enough to cover the skin completely and do not spray the face. This can be dangerous because the child can inhale the aerosol so make sure you spray your hands first then apply the sunscreen to the child’s face.

For babies younger than 6 months, it is recommended to keep them in the shade, but if they must be out in the sun, make sure to use a broad-spectrum SPF that is waterproof and cover the skin completely and apply every 2 hours.

Summer is here so make sure to stock up on sunscreen and apply it daily. This includes moisturizers under makeup with SPF. If you should get sunburned, treat it as soon as possible by taking a cool bath to reduce the heat, stay moisturized, stay well hydrated and use hydrocortisone cream and aspirin or ibuprofen as needed for discomfort.
