How can I safely treat lye on skin to prevent further damage and promote healing?

To safely treat lye on skin, immediately rinse the affected area with cool water for at least 15 minutes. Do not use hot water as it can worsen the burn. Gently pat the skin dry and cover it with a clean, dry bandage. Seek medical attention if the burn is severe or covers a large area. Avoid applying any creams or ointments without consulting a healthcare professional.
