Nanofat vs Microfat: Two Tools, Two Different Jobs

Modern facial fat grafting isn't one substance — it's a small toolkit made from the same harvested fat, prepared differently for different jobs. The two terms you'll meet are microfat and nanofat, and knowing the difference makes consultation conversations much clearer.

Microfat: the volume tool

Microfat is purified fat with intact fat cells, harvested and placed through fine cannulas. Its job is structure and volume: rebuilding cheek projection, filling temple hollows, supporting the jawline, softening deep folds. When people picture fat transfer results, they're picturing microfat's work. Placed properly — tiny threads, multiple planes — a meaningful portion survives long-term as living tissue.

Nanofat: the skin-quality tool

Nanofat starts as the same fat, then is mechanically emulsified and filtered until the mature fat cells are broken down. What remains is a fluid rich in regenerative cells and growth factors — stromal cells that influence tissue quality rather than adding bulk. Nanofat adds essentially no volume; its job is different:

• Fine lines and crepey texture (around the eyes and mouth)
• Dark, thin under-eye skin
• Overall skin quality in ageing or sun-damaged areas
• Scarred tissue, where it can improve suppleness

Effects develop gradually over months and vary between patients — real, but properly framed as improvement in skin quality, not a resurfacing laser in a syringe.

Why plans combine them

An ageing face usually has both problems at once: lost volume (a microfat job) and declining skin quality (a nanofat job). A typical combined plan places microfat deep for structure — cheeks, tear trough support, temples — and layers nanofat superficially where texture and skin tone need help, most classically the under-eye area. Same donor fat, one procedure, two mechanisms.

Questions this should raise at your consultation

• "Which of my concerns are volume problems, and which are skin-quality problems?"
• "Where would you use microfat, and would nanofat add anything in my case?"
• "What realistic change should I expect from each?"

A surgeon who separates these clearly is planning your face rather than reciting a menu — exactly what you want in an operation where judgement is the main technology.
