Protect Yourself from Photodamage this Summer

Harmful UV rays, oxidative-stress, and solar-damaged skin- these are all the things you want to try to avoid this summer. With the season getting hotter and the rays getting harsher, you may also want to consider tweaking your beauty regimen. Not only will it help protect your skin from accelerated aging, but it’ll also decrease your risk of cancer. Find out what photodamage consists of, how to avoid it, and how to treat it if you've already been exposed.

What is Photodamage?

Also referred to as photoaging or sun damage, photodamage is the destruction of our skin health after prolonged exposure to ultraviolet radiation. It can actually cause DNA changes at the cellular level, working its way to the deepest layers of the skin: the dermis. Because of this, it can take a long time before the damage becomes apparent at surface level.

What are the Signs?

You can start to see signs of photoaging beginning in your late teens to early 20s. Some of these signs include:

• Fine lines & wrinkles
• Brown spots & changes in pigmentation
• Decreased elasticity
• Rough, uneven skin tone & texture
• Broken capillaries (typically around the nose/chest area)
• Increased redness/blotchiness

Types of UV Light

To better understand what causes photodamage, you would need to know the types of ultraviolet radiation that exists. In general, there are 3 main types:

1. UVA Light- This is a form of solar radiation that has the potential to damage the skin at all levels. This means it can affect the epidermis all the way down to the dermis. As a result, many parts of the skin are influenced such as the elastin fibers and blood vessels (capillaries).
2. UVB Light- This type of radiation affects the outer layer of the skin. While it only targets the surface, it’s more threatening than UVA light because it may cause precancerous cells to form.
3. UVC Light- This is the least potent form of UV light. Much of this radiation is absorbed by the ozone layer and atmosphere.

The Fitzpatrick Scale

While everyone is susceptible to photodamage, there are many factors that can determine who will be more vulnerable to it than others. Besides geographical location and climate, knowing your skin type is also important. Generally speaking, lighter skin types are more at risk for accelerated aging and skin cancer. Darker skin types, on the other hand, will more than likely develop uneven skin tone, or melasma. To find out what skin type you fall under, dermatologists will often use the Fitzpatrick Scale:Type I- Pale skin, light-colored eyes, blond or red hair. Always burns, does not tan.Type II- Fair skin with light-colored eyes. Burns easily but may tan.Type III- Medium light skin that initially burns and then tans.Type IV- Light brown skin that tans with minimal burning.Type V- Medium brown skin that rarely burns.Type VI- Dark brown or black skin that tans easily and never burns.

How to Prevent Photodamage

Sunscreen is your best friend this summer. Most experts will recommend you use a broad-spectrum sunscreen that contains both UVA and UVB protection. You’ll also want to look for sunscreens that have at least SPF 30. If you’re currently on the lookout for one, try my Ultimatte Perfect Sun Shield. This mineral based sunscreen contains:zinc oxide, iron oxide, titanium dioxide, green tea polyphenols, ceramides and more, to help you combat sun damage. It also offers both UVA/UVB protection & SPF 50.

How to Treat Photodamage

If you’re already noticing signs of sun damage, it’s time to consider the next steps. While photoaging isn’t completely reversible, there are a wide variety of treatments available to help minimize it. Some of these treatments include:

• Lasers
• Chemical Peels (We offer this at our clinic! Call our office to learn more.)
• Retinoids
• Photodynamic Therapy
• Cryotherapy

Final Thoughts

While the consequences of sun exposure may not show up at first, it’ll definitely come back later to haunt you. Many clients who experience photodamage regret not taking action sooner! Don’t let this happen to you, and start taking the right preventative steps now.
