Let me preface this article by saying I see tons of "AKs" all the time. They can show up almost overnight, and can be a 'pay-back' from years of excess sun exposure. You might not have any, and at some point they seem to pop-up all over the place. On visual inspection, new lesions may look like little starbursts of broken capillaries.

They seem especially common on the nose, cheeks, and perimeter of the face (maybe, you're not applying adequate sunscreen there?). Many times I will examine them under my Dermlite Dermatoscope which has a polarized lens which helps me differentiate an AK from a broken capillary.

Some of them have a unique look under microscopy similar to a tangle of red spaghetti-like vessels and enlarged globular cells.

Prevention is your very best therapy!

I strongly encourage pro-active preventatives: routine visits, specific serums, mineral sunscreen use, antioxidant nutritional supplemets, occasional chemical peels, and specific skincare regimens that build up the health of the tissue, rather than break it down and make it vulnerable. Facial services are NOT a substitute for your annual dermatological skin cancer examination. I will not ever treat any suspicious lesions. You will be advised to see your dermatologist.

What is actinic keratosis? 

Actinic keratosis is a rough, scaly patch or bump on the skin. It’s also known as a solar keratosis. Actinic keratoses are very common, and many people have them. They are caused by ultraviolet (UV) damage to the skin. Some actinic keratoses can turn into squamous cell skin cancer. Because of this, the lesions are often called precancer. They are not life-threatening. But if they are found and treated early, they do not have the chance to develop into skin cancer.

What are the risk factors for actinic keratosis?

UV rays from the sun and from tanning beds cause almost all actinic keratoses. Damage to the skin from UV rays builds up over time. This means that even short-term exposure to sun on a regular basis can build up over a lifetime and increase the risk of actinic keratoses. Some people are more at risk than others, including:
People with pale skin, blonde or red hair, and blue, green, or gray eyes

• People with darker skin, hair, and eyes who have been exposed to UV rays without protection
• Older adults
• People with suppressed immune systems (due to chemotherapy, AIDS, organ transplant, or other causes)
• People with rare conditions that make the skin very sensitive to UV rays, such as albinism or xeroderma pigmentosum (XP)

What are the symptoms of actinic keratosis?

Ak's are most likely to appear on areas of skin often exposed to the sun. These can include the face, ears, bald scalp, neck, backs of hands and forearms, and lips. It tends to lie flat against the skin of the head and neck, but appears as a bump on arms and hands. The base of an actinic keratosis may be light or dark, tan, pink, red, or a combination of these - or it may be the same color as the skin. The scale or crust may be horny, dry, and rough. In some cases, it may itch or have a prickly or sore feeling.

Often, a person will have more than one actinic keratosis lesion. Actinic keratoses that develop on the lip are called actinic cheilitis.

How is actinic keratosis diagnosed?

Your esthetician may help in identify but not diagnose them - your Healthcare professional will provide a definative diagnose of an actinic keratosis by looking at and feeling the area on your skin. Sometimes an actinic keratosis can be hard to tell apart from skin cancer. Your healthcare provider might remove the area of skin to have it checked under a high-powered microscope by a pathologist. This is known as a skin biopsy.

How is actinic keratosis treated?

Treatment for an actinic keratosis may include:

• Cryotherapy. This treatment freezes the lesion.
• Topical chemotherapy. This is medicine applied to the skin. This is an aggressive therapy used for weeks and can be a burning, uncomfortable process.
• Laser surgery. This can remove lesions from the face and scalp, and actinic cheilitis from the lips.
• Other treatments. Some small, new AK's can be treated in-spa with Skin Classic as a preliminary treatment.

Many dermatologist will okay this therapy as a first step if they are small & benign. If there are many, they come back, change, or enlarge, you WILL be strongly encouraged to see your dermatologist, and they will not be re-treated in-spa.

Most actinic keratoses can be medically treated and cured. In rare cases they may come back. It’s important to have regular skin exams after treatment.
