A blade, or a needle
The fundamental difference is the tool. Microblading works with a blade made of aligned micro-needles that incises the skin to deposit pigment. Nano uses a single very fine needle, guided by a digital machine, that deposits pigment point by point without cutting. Skin does not respond to the two gestures in the same way.
Healing guides the choice
Because the blade incises, microblading can leave more visible marks in some skin, especially after several touch-ups. Oily, sensitive and mature skin are more exposed to this. Single-needle work allows a more controlled deposit that tends to heal more evenly.
Not every skin type responds the same way
On skin that produces more sebum, incised strokes tend to blur and lose their crispness faster. This is one of the reasons the Nano technique — more progressive and more precise — became the Muse specialty: it offers better control across more skin types.
Aging well, or correcting later
Permanent makeup is also judged over time. A stroke deposited without incising tends to evolve more cleanly than a cut stroke, and part of Muse’s work is precisely assessing older microblading whose colour or shape has aged poorly. If that is your situation, have your starting point assessed before booking.
