The Cycle
Interactive prototype · click a phase on the wheel, or scroll — the wheel follows. Per-product guidance is placeholder until Muyu Bundle contents are confirmed.
The science, simply
Your skin doesn't stay the same all month. Your routine shouldn't either.
Estrogen and progesterone rise and fall across your cycle — shifting your skin's oil, hydration, and sensitivity week to week. Cycle-synced skincare meets your skin where it is.

Cycle looks different for you?
You don't need a textbook 28-day cycle.
Most people don't track perfectly — and many don't bleed on a schedule at all. Your skin still shifts; we'll teach you to read its signals instead of the calendar.
On birth control
Hormonal contraception flattens the natural swing. Read your skin by how it feels, not the date — your routine still adapts.
Perimenopause
Cycles get shorter and less predictable as estrogen declines. Expect more dryness and sensitivity — lean into barrier care.
Irregular cycles
PCOS, postpartum, or simply irregular? Track skin signals — oiliness, breakouts, tightness — and respond to those.
