At a day spa or beauty salon, your main job duties include performing beauty treatments on the hands, feet, and faces of clients. Most beauty therapists also provide advice on the best personal skin care treatments for clients to use at home. You also recommend the best beauty products for each client. Other common duties include removing hair, applying false nails or eyelashes, giving spray tans, and providing stress-reducing massages. Some beauty therapists offer general services while others specialize in one area.
