When dealing with a persistent skin patch, especially one that you've had for years, it's important to first identify the underlying cause to determine the most effective treatment. Here are some general steps and options you might consider:

Consult a Dermatologist: The first step should be to consult with a board-certified dermatologist who can examine the patches and provide a precise diagnosis. Common causes of persistent skin patches include psoriasis, eczema, fungal infections, or even post-inflammatory hyperpigmentation.

Topical Treatments: Depending on the diagnosis, your dermatologist might recommend topical treatments:

Corticosteroids: These can reduce inflammation and are often prescribed for conditions like eczema or psoriasis.
Antifungal Creams: If a fungal infection is suspected, antifungal treatments may be appropriate.
Moisturizers: Keeping the skin well-moisturized can help with conditions like eczema.
Medications: For more chronic conditions, systemic medications might be necessary:

Oral or Injectable Medications: For severe psoriasis or eczema, medications that modulate the immune system might be recommended.
Laser Therapy: For certain types of discoloration or persistent patches, laser therapy might be an option to improve the appearance of the skin.

Lifestyle and Home Remedies: In addition to medical treatments, consider:

Avoiding Triggers: Identify and avoid any potential irritants or allergens that might be exacerbating the condition.
Healthy Skin Practices: Regularly moisturizing and protecting the skin from excessive sun exposure can help maintain skin health.
Follow-up: It’s essential to follow up with your dermatologist to monitor the condition and adjust treatments as necessary.

Ultimately, the best course of action is to seek a professional evaluation to tailor the treatment to your specific condition.
