Starrflesh , also written as Starflesh , is a surreal internet aesthetic that revolves around characteristics such as teeth, scales, deformed animal motifs, water, glass, and the feeling of emptiness, uncanny, or rage. The aesthetic began gaining traction on Tumblr in the early-to-mid 2010s, initially circulating under generic labels like "icecore" or "coldcore." It was later revived and mistakenly named after the username of its primary popularizer, @starrflesh on TikTok. However, the original creator has since publicly distanced themselves from this aesthetic and does not wish to be viewed as its current authority.

The aesthetic is mainly documented through eerie and mysterious photographs that are heavily edited with icy blue overlays and effects to enhance the surreal and horror elements. Many of the pictures are extremely disturbing, featuring deformed animals, flesh, blood, and elements of body horror. Note that due to the explicit and highly distressing nature of the images, the aesthetic is often difficult to archive, resulting in broken links and a high potential for viewer distress.

This aesthetic is visually calming, cold, and eerie. Some commonly used characteristics are:

Common colors seen in starrflesh fashion mostly include white, but red, blue, black, and dark greens can also be incorporated.
