Photodynamic Therapy (PDT) provides an innovative approach in treating precancerous lesions and some types of acne. By using photosensitive medication activated by specific wavelengths of light, it selectively destroys abnormal cells while sparing surrounding healthy tissues.

• Mechanism of Action: The treatment involves applying a topical photosensitizing agent that is absorbed by targeted cells before exposure to activating light which leads to cell destruction.'

Chemical Peels are cosmetic procedures aimed at enhancing skin texture through controlled exfoliation. Various acids are applied to target different layers of the skin to treat conditions like acne scars, sun damage, and pigmentation issues effectively.

• Types of Peels: Superficial peels use mild acids for light exfoliation; medium peels penetrate deeper for more significant results; deep peels provide intensive improvements but require longer recovery times.
• Indications: Ideal for those struggling with hyperpigmentation, acne scars, or uneven skin tone.
• Preparation & Aftercare: Pre-procedure care might involve avoiding certain medications; aftercare usually requires diligent sunscreen use and moisturizing routines to protect healing skin.

This versatile treatment can be tailored according to individual needs and is effective in enhancing overall complexion when done correctly.

Mohs Micrographic Surgery is a specialized surgical technique used to treat skin cancer while preserving as much healthy tissue as possible. It involves removing the cancerous skin layer by layer and examining each layer for cancer cells until no further cancerous cells are detected.

• Symptoms: Skin cancers often present as unusual growths, sores that don't heal, or changes in existing moles.
• Diagnosis: Diagnosis typically involves a physical examination, biopsy, and histopathological evaluation of skin lesions.
• Treatment Options: Mohs surgery is the primary treatment option which allows for immediate examination of excised tissue; alternative treatments may include topical chemotherapy or radiation therapy.
• What to Expect: Patients can expect a day-long procedure with local anesthesia, a high success rate in cancer removal, and minimal scarring when performed by skilled professionals.

This method is particularly effective for certain types of skin cancers and offers excellent cosmetic results.
