Actinic Keratosis: Causes, Symptoms, Treatment & How to Get an Online Doctor’s Certificate
Actinic keratosis (AK) is a common precancerous skin condition that develops due to prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. If left untreated, it can progress to squamous cell carcinoma, a type of skin cancer. Understanding the causes, symptoms, and treatment options can help with early detection and effective management. 🏥
Actinic keratosis, also known as solar keratosis, appears as rough, scaly patches on sun-exposed areas such as the face, scalp, hands, and arms. These lesions develop due to long-term sun damage, making prevention and early treatment crucial in reducing the risk of skin cancer.
Actinic keratosis is caused by cumulative exposure to UV radiation, leading to DNA damage in skin cells. Risk factors include:
Excessive sun exposure 🌅
Fair skin, light-colored eyes, and blonde or red hair 👩🦰
History of sunburns 🔥
A weakened immune system 🦠
Older age (50+) 👴
Outdoor occupations (e.g., farmers, construction workers) 🚜
The most common signs of actinic keratosis include:
Rough, dry, or scaly patches on the skin 🏜️
Small, flat, or slightly raised bumps that may be red, brown, or pink 🎨
Itching, burning, or tenderness 🔥
Cracked or crusted skin 🩹
These lesions may appear individually or in clusters, often in sun-exposed areas.
A dermatologist can diagnose actinic keratosis through visual examination and, if necessary, a skin biopsy to rule out skin cancer. Early diagnosis allows for prompt treatment and reduces the risk of progression.
Effective treatments for actinic keratosis include:
5-fluorouracil (5-FU) cream – A chemotherapy cream that destroys abnormal skin cells.
Imiquimod (Aldara, Zyclara) – Boosts the immune system to fight precancerous cells.
Diclofenac gel – A non-steroidal anti-inflammatory that reduces lesion growth.
Liquid nitrogen is used to freeze and destroy abnormal skin cells.
A light-based treatment combined with a special photosensitizing agent.
Helps remove damaged skin layers and promote healthy skin regeneration.
The best way to prevent actinic keratosis is by protecting your skin from UV damage:
Wear sunscreen (SPF 30+) daily ☀️
Avoid tanning beds 🚫
Wear protective clothing, hats, and sunglasses 🧢
Seek shade during peak sun hours (10 AM - 4 PM) ⏳
Regular skin checks with a dermatologist 🔍
