Tretinoin, a topical retinoid, can help treat certain types of precancerous skin lesions.
What is Tretinoin?
Tretinoin is a form of vitamin A that is used to treat acne, wrinkles, and precancerous skin lesions. It is available by prescription only.
How Does Tretinoin Work?
Tretinoin works by speeding up the skin's cell turnover rate. This helps to remove abnormal cells and prevent the development of cancer.
Precancerous Skin Lesions
Precancerous skin lesions are areas of abnormal skin cells that have the potential to become cancerous. Some common types of precancerous skin lesions include:
- Actinic keratosis (AK): These are rough, scaly patches that often appear on sun-exposed skin.
- Bowen's disease: This is a type of squamous cell carcinoma (SCC) that affects the top layer of skin.
Tretinoin for Precancerous Skin Lesions
Tretinoin is often used to treat actinic keratosis. It can also be used to treat Bowen's disease, but other treatments are often preferred.
Benefits of Tretinoin for Precancerous Skin Lesions
- Reduces the risk of skin cancer: Tretinoin can help to prevent precancerous lesions from developing into cancer.
- Reduces the size and number of lesions: Tretinoin can help to shrink and clear existing lesions.
Risks and Side Effects of Tretinoin
Tretinoin can cause side effects, such as:
- Redness and irritation: This is the most common side effect.
- Dryness and peeling: Tretinoin can make your skin dry and flaky.
- Sun sensitivity: Tretinoin can make your skin more sensitive to the sun.
Important Note
It is important to talk to your doctor before using tretinoin for precancerous skin lesions. They can help you determine if tretinoin is right for you and how to use it safely.
