We sit down with board-certified dermatologist and associate professor Dr. Walter Liszewski to break down the science, safety, and art of tattooing—from how ink settles into the dermis to what really happens during healing, fading, and removal. He shares what matters most: finding a reputable artist, spotting real hygiene, and understanding how regulations differ across states.We also explore tattoo reactions and skin health, from red-ink allergies and pigment-holding macrophages to what lymph node staining actually means. Dr. Liszewski explains when skin conditions like psoriasis, vitiligo, or sarcoidosis should shape your tattoo choices, and how medical tattooing—like areola recreation or scar camouflage—can restore confidence. Whether you’re getting your first tattoo or removing one, this episode helps you make informed, skin-smart choices about your ink.
