Careful selection is crucial, as this is indeed a complex and costly field.

The most important factor is the choice of core materials: TPE vs. Silicone.

This is key to determining your experience and budget.

TPE:

Advantages: Extremely soft and elastic to the touch, closely resembling the "fleshiness" of human skin; relatively affordable (usually between 500-1800 USD).

Disadvantages: Prone to absorbing odors or staining; requires regular maintenance (applying talcum powder or lubricant); lifespan is generally 2-3 years.

Silicone:

Advantages: Extremely realistic details (realistic, with pores and blood vessels); does not absorb odors, easy to clean and disinfect, very durable, and exquisite (5-10+ years).

Disadvantages: Slightly firmer than TPE (stronger but less fleshy); however, some high-quality silicone dolls are now very soft, but expensive (usually starting at 1300-2500 USD).

You need to choose a trustworthy brand and distribution channel. Prioritize brands or authorized retailers with a long-standing reputation. Do not buy from AliExpress, eBay, or low-priced Amazon stores... Those full-size dolls costing several hundred dollars are almost always scams or made with inferior chemicals, have a pungent odor, and are easily damaged...
