MimiSilk Iris vs Tria FRX
MimiSilk Iris and Tria FRX compared on published specifications. Both use the same technology (non-ablative fractional laser), so the differences are in wavelengths, output, form, routine and price. MimiSilk Iris: 1450 nm, session 5–10 min, €535.95. Tria FRX: 1440 nm, session 2–10 min, by setting, US$699.99.

What the differences mean
Both use the same technology (non-ablative fractional laser), so the differences are in wavelengths, output, form, routine and price.
A non-ablative fractional laser fires a grid of microscopic heat columns, called microthermal treatment zones, into the dermis. The skin between the columns stays intact and heals each zone quickly, which drives collagen remodelling. Wavelengths around 1440–1550 nm are absorbed by water in the skin, so the effect does not depend on skin pigment.
MimiSilk Iris
MimiSilk brings fractional laser technology to a lower price point: the Iris is a 1450 nm non-ablative fractional device with five pre-set facial zones, a child lock and a design that has won product-design awards.
Suited to: Texture, pores and shallow acne marks (brand indications); Wanting fractional technology at a lower price.
Tria FRX
Tria has held FDA clearances for home-use lasers since 2010, and the FRX is its second-generation fractional device: a 1440 nm non-ablative fractional laser that creates microscopic treatment zones, the same principle used by in-clinic resurfacing lasers.
Suited to: Texture, tone, dark spots and fine lines (brand indications); Willing to follow a structured 12-week programme.
