A concealer in the skin, not bulk filling
Concealer fat grafting is for surface dark circles — not for filling hollows.
ST’s video explanation contrasts ordinary, deeper fat grafting with a finer “concealer” graft: very finely prepared fat is placed in a shallow layer near the skin to mask a dark circle that shows through thin lower-eyelid skin. It is a surface refinement after repositioning — not a deep hollow filler and not a shortcut for every dark circle.
Dimension
Ordinary deep filling mindset
ST concealer-style grafting
Indication
Added whenever the under-eye looks dark or hollow.
Used after structural correction, only when a see-through dark circle still shows at the surface.
Particle behavior
Coarser grafts or filler can sit as a lump in the thin lower-eyelid area.
Finer prepared fat is designed to spread more evenly in delicate under-eye tissue.
Relationship to repositioning
Used to cover a problem that may still be structural.
Supports ligament release and fat repositioning after the main contour is corrected.
Revision concern
Poorly placed filler, collagen, or fat can make later revision more difficult.
The plan avoids adding unnecessary material when the native fat can be repositioned instead.
