Understanding Actinic Keratoses: A Milady Standard Approach

Actinic keratoses (AKs), also known as solar keratoses, are common precancerous skin lesions caused by prolonged and excessive sun exposure. So we will explore their causes, symptoms, diagnosis, treatment options, and preventative measures. This article provides a comprehensive understanding of AKs, aligning with the standards expected in a Milady cosmetology curriculum and beyond. Understanding AKs is crucial for skincare professionals, as early detection and patient education are vital in preventing the development of squamous cell carcinoma (SCC), a more serious form of skin cancer.

What are Actinic Keratoses?

Actinic keratoses are rough, scaly patches that typically appear on sun-exposed skin. They are considered precancerous, meaning they have the potential to develop into squamous cell carcinoma (SCC), a type of skin cancer. While not all AKs will transform into SCC, it's vital to monitor and treat them to minimize this risk. The lesions are a direct result of cumulative sun damage over time, highlighting the critical importance of sun protection. The term "actinic" refers to the action of light (specifically ultraviolet radiation from the sun) and "keratosis" refers to a thickening of the skin.

Causes and Risk Factors of Actinic Keratoses

The primary cause of AKs is cumulative exposure to ultraviolet (UV) radiation from the sun. This includes both UVA and UVB rays, both of which damage DNA in skin cells. The longer and more intense the sun exposure, the greater the risk of developing AKs.

• Fair Skin: Individuals with lighter skin tones, particularly those with freckles and light hair, are at a significantly higher risk. Their skin contains less melanin, the pigment that protects against UV damage.
• Age: The risk of developing AKs increases with age, as cumulative sun damage accumulates over a lifetime. People over 50 are at a much higher risk.
• Weakened Immune System: Individuals with compromised immune systems, whether due to illness or medication, are more vulnerable to developing AKs and their progression to SCC.
• History of Sunburns: Severe sunburns, especially during childhood, significantly increase the risk of developing AKs and other skin cancers later in life.
• Outdoor Occupations: People who work outdoors for prolonged periods, such as farmers, construction workers, and lifeguards, are at increased risk.
• Family History: A family history of skin cancer, including AKs and SCC, increases an individual's risk.
• Excessive Tanning Bed Use: Using tanning beds exposes the skin to high levels of UV radiation, significantly increasing the risk of AKs and other skin cancers.

Symptoms and Appearance of Actinic Keratoses

AKs can present in various ways, making diagnosis challenging. They are often subtle and can be mistaken for other skin conditions. Common characteristics include:

• Rough, Scaly Patches: AKs typically appear as rough, scaly, and slightly raised patches on the skin.
• Color Variation: The color can vary from pink or red to brown or flesh-toned. Some may be darker or even black.
• Location: They usually appear on sun-exposed areas like the face, ears, scalp, neck, hands, forearms, and back.
• Texture: The texture is often described as sandpaper-like or rough to the touch.
• Itching or Bleeding: Some AKs may be itchy or bleed easily. This is a significant warning sign and should warrant immediate medical attention.
• Pain: While usually painless, some lesions can cause discomfort or pain.

Diagnosing Actinic Keratoses

Diagnosis of AKs is typically made through a physical examination by a dermatologist or healthcare professional. They will carefully examine the skin lesion, considering its appearance, location, and the patient's history of sun exposure. To confirm the diagnosis and rule out other conditions, additional diagnostic methods may be used:

• Dermoscopy: This technique uses a special magnifying device to examine the lesion's structure and characteristics in detail.
• Biopsy: A small tissue sample is taken from the lesion and examined under a microscope. This is the most definitive way to diagnose AKs and confirm they are not cancerous. A biopsy is especially crucial if the lesion shows unusual characteristics or has signs of growth or change.

Treatment Options for Actinic Keratoses

Treatment for AKs aims to eliminate the lesions and prevent their progression to SCC. Several methods are available, each with its own advantages and disadvantages:

• Topical Medications: Creams, gels, or lotions containing ingredients like fluorouracil (5-FU), imiquimod, diclofenac, or ingenol mebutate are often used to treat AKs. These medications work by destroying the abnormal skin cells. Treatment typically involves applying the medication to the affected area for several weeks. Side effects can include redness, inflammation, and skin irritation.

• Cryotherapy: This involves freezing the AKs with liquid nitrogen. The freezing destroys the abnormal cells. It's often used for small, individual lesions and can cause temporary blistering and discoloration.

• Photodynamic Therapy (PDT): PDT involves applying a photosensitizing drug to the skin, followed by exposure to a specific type of light. The drug makes the abnormal cells more sensitive to light, causing their destruction. PDT is effective but can cause temporary skin redness and swelling.

• Surgical Excision: Surgical removal is an option for larger or more concerning lesions. The AK is surgically cut away, and the area is closed with stitches. This is a more invasive procedure and may leave a scar.

• Curettage and Electrodessication: This involves scraping away the AK with a curette, followed by destroying the remaining cells with an electric needle. This method is often used for smaller lesions.

Preventing Actinic Keratoses: Sun Protection is Key

Preventing AKs is crucial, as it's far easier to prevent them than to treat them. The most effective way to reduce the risk is through consistent and comprehensive sun protection:

• Sunscreen: Regularly apply a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin, even on cloudy days. Reapply every two hours, or more frequently if swimming or sweating.

• Protective Clothing: Wear protective clothing, such as long-sleeved shirts, long pants, and wide-brimmed hats, to minimize sun exposure. Worth keeping that in mind.

• Seek Shade: Limit sun exposure during peak hours (10 a.m. to 4 p.m.) when the sun's rays are strongest. Seek shade whenever possible.

• Sunglasses: Wear sunglasses that block 99-100% of UVA and UVB rays to protect the delicate skin around the eyes.

• Regular Skin Exams: Perform regular self-skin exams to check for any changes in your skin, including new moles, spots, or lesions. Consult a dermatologist for professional skin exams, especially if you have a family history of skin cancer.

Actinic Keratoses and Cosmetology: The Esthetician's Role

Estheticians play a vital role in educating clients about sun protection and early detection of skin cancer. While estheticians cannot diagnose or treat AKs, they can:

• Educate Clients: Provide clients with information about sun protection, the importance of regular self-skin exams, and the signs and symptoms of AKs.
• Referrals: Refer clients with suspicious lesions to a dermatologist or healthcare professional for diagnosis and treatment.
• Promote Sun Safety: Encourage clients to use sunscreen and protective clothing, especially during sun exposure.
• Observe Skin: During treatments, carefully observe the client's skin for any unusual changes or lesions. Document findings and relay concerns to the client and recommend a consultation with a dermatologist.
