Female voice, professional dermatologist / doctor tone. Calm, warm, confident, and reassuring voice. Natural speaking style, slightly slow pace, no rushing. Natural breathing between sentences. Clear and clean pronunciation. No exaggeration, no drama, no aggressive advertising tone. Feels like a doctor sitting in her office, calmly explaining to a patient. Soft, steady volume — not loud, not whispering. If background music is used, it should be very light, simple ambient music that does not overpower the voice. Full focus on clarity, trust, and comfort.
