Estrogen fluctuates. Every cycle.
In the days before a period, estrogen levels drop sharply while progesterone tries to compensate. This shift is normal and inevitable.
What the research describes:
- Testosterone becomes relatively dominant → sebaceous glands produce more oil
- Skin often reacts → particularly along the jawline
- Vitamin B6 contributes to the regulation of hormonal activity
SIGNS HORMONES ARE THE TRIGGER
- Estrogen falls in the days before a period
- Progesterone rises, then falls too
- Testosterone becomes relatively dominant
- The pattern repeats with every cycle
