Facial realism deserves particular focus because the face is where people instinctively look first. High-quality glass or acrylic eyes with detailed irises and natural depth can make a dramatic difference. Proper eye placement and alignment are essential; even slight asymmetry can make silicone sex dolls appear more lifelike, since perfect symmetry is rare in real faces. Eyelashes should be carefully attached or implanted to avoid stiffness, and eyebrows can be individually punched or hand-painted for a softer, more natural expression.
