The Equation for Beauty
P = λ(nD)t — Lumielina's Equation for Beauty

The power to become beautiful is a function of the density of the Bioprogramming field (D) and the time spent within it (t). Choosing a higher density is choosing a higher ceiling.

§ Why this D

Where 7D
sits.

Every Lumielina device is rated by the density of its ionic field. Higher D compresses more work into the same time — less heat exposure, more durable result. Pairs of equivalent D (Repronizer + HairBeauron) form the discipline of Mitsudonose.
