BODY, MATERIAL & REALISM
Realistic Skin Texture (RST)
At the most basic level silicone dolls fall into two categories: those without physical skin texture or with light software-made texture, and those with realistic skin texture taken from real women. Both can look beautiful — but the way they are made, and the realism they achieve, is very different.
01
PAINT VS PHYSICAL DETAIL
What RST Actually Is
Traditional dolls rely on skin painting — speckles, shading and veins applied to a smooth surface. RST goes further: micro bumps and pores, natural skin irregularities and subtle texture on breasts, hands, feet and intimate zones are sculpted into the mould itself, so the finished doll has real, touchable texture.

02
THE MIDDLE TIER
Micro-Grain 3D Modelled Texture
Some silicone dolls carry a very shallow physical texture from the mould in certain places only — hands and feet, the pubic area and areolas. This is software-modelled micro-grain texture rather than texture captured from real human skin.

03
INSIDE THE FACTORY
How RST Is Created
Factories add an extra sculpting stage. The prototype is fully coated in clay, then sculptors add texture by hand — or transpose a gel cast taken directly from real human skin into the clay. Once the mould is made from that surface, every doll poured from it carries the detail permanently. Slower and more expensive, but unmistakable.

Irontech — T Series
The T Series, including the Naturally Optimized and Wonder Dolly ranges, uses replicated lifelike light skin textures based on real human skin. The new 171cm body uses 3D-modelled realistic human skin texture. All other Irontech silicone models carry 3D micro-grain texture instead. Most textured bodies: 158T, 159T, 164T, 165T (not all bodies).

Real Lady — RST as Standard
All Real Lady dolls are made with full Realistic Skin Texture from real women — there is no other option. The entire body is based on realistic human anatomy including muscles, bones and blood vessels, and every part of the skin texture is replicated from real women’s skin. Real Lady are the Lexus to Irontech’s Toyota.

Top Cy Doll — RST Upgrade
Top Cy offer RST as an optional upgrade across their range. Their standard silicone dolls use 3D-modelled micro-grain texture; the RST upgrade uses skin texture captured directly from real women for a deeper, more lifelike result. Look for it under the Custom Made button.

Tayu — True Skin Texture
Tayu use their own marketing term, True Skin Texture, featured on their 163cm D Cup doll. As with Irontech and Top Cy, their standard silicone dolls have light software-created texture — this is the one to choose for their best realism. One model so far, 162cm.

BUYER’S GUIDE
Compare Like For Like
When comparing prices, factor in how each brand handles RST. Fanreal and Top Cy charge for it as an upgrade, while with Real Lady it is standard and built into the price. Weighing Real Lady against Fanreal or Top Cy? Compare the cost with RST included to level the playing field.

MOVEMENT, POSING & DURABILITY
Starpery Ballet (Interaction Optimized) Skeleton
Seven core upgrades from Starpery — and the geared joint system underneath them. Ankles-as-earrings fans, get ready.
01
CORE UPGRADE
0° Hip Joint Design
The upgraded hip structure allows the thighs to sit naturally flush against the abdomen, dramatically improving comfort and realism. Movement is smooth and intuitive, making pose changes easier, more fluid and far more natural than traditional designs.
Compare & shop →
02
CORE UPGRADE
180° Spine Rotation
The waist joint now supports a wider rotational range with exceptionally smooth, non-sticky motion. This allows the body to form a graceful, lifelike S curve, enhancing posture realism and expanding expressive posing possibilities.
Compare & shop →
03
CORE UPGRADE
360° Precision Neck Ball Joint
Similar to the Zelex ball joint skeleton, Starpery combine a ball-jointed neck with gear skeleton joints. Manufactured from high-temperature resistant carbon steel (tested up to 1400°C) with micron-level precision engineering, it has passed thousands of durability tests without loosening or cracking. The head can rest naturally toward the shoulders.

04
CORE UPGRADE
New Articulated Finger Bone Structure
The thumb can now adduct naturally toward the palm, restoring realistic hand mechanics. This allows more delicate gestures, accurate grasping and a level of hand expressiveness previously unseen at this level.

05
CORE UPGRADE
Forearm Rotation with Wrist-Twist Prevention
An optimised linkage system keeps the wrist correctly aligned during forearm rotation. With a smooth 180° left-right rotation range, movements feel natural and strain-free, allowing precise hand-to-hand positioning without distortion.

06
CORE UPGRADE
Ballet-Grade Foot Joint
The feet support 90° lateral torsion as well as forward and backward flexion. The sole can bend into a soft concave arc, enhancing both visual realism and responsive positioning. Even subtle contact produces natural, lifelike reactions.

07
CORE UPGRADE
Fully Articulated Phalange Bones
All finger knuckles are now independently movable, dramatically expanding the range of possible hand poses. The same hand design features in all Lushdoll silicone models, the Irontech Oriental series and the Zelex V2 Inspiration upgrade — currently the best in hand skeleton design.

WHY IT MATTERS
Geared Joints vs Welded Joints
Starpery were one of the first manufacturers to adopt an almost fully geared skeleton. Conventional skeletons rely on U-brackets, bolts and welded nuts, where weld failure over time can loosen joints and force invasive repairs. Geared joints use precision-cut interlocking teeth to distribute load evenly and hold long-term structural integrity.
