Scent can enhance realism and immersion, but it must be chosen with care to avoid skin irritation and damage. Opt for fragrance-free or hypoallergenic products designed for sensitive skin, especially if the doll’s surface is in close contact with these substances. If you want a subtle scent, apply a minimal amount to a cloth or fabric insert rather than directly onto the skin-like surface. Essential oils can be used sparingly only if they are properly diluted and known to be safe for synthetic materials; test on a small, inconspicuous area first. Avoid strong, lingering, or solvent-based scents that can degrade finishes or cause discoloration over time. Keep scents out of any joints, creases, or adhesives where they can accumulate and attract dust or degrade materials. For maintenance, limit scent application to after cleaning sessions to keep the doll fresh without saturating the environment. If a particular scent ever causes irritation or a strange reaction on the surface, discontinue use immediately and re-check compatibility with the doll’s material and care guidelines. Subtlety and caution are the keys to a pleasing, non-damaging aroma.
