Your skin isn't moody. It's cyclical.

What your hormones do to your skin across one month, and why a routine that never changes can't keep up.

For years, we were told our skin was "difficult". Too oily one week, too dry the next, breaking out for no reason. There is a reason. It just wasn't explained to us.

Your hormones talk. Your skin listens.

Oestrogen and progesterone don't stay level across the month. They rise and fall, and with them, your skin's sebum, hydration, inflammation and sensitivity. Yet almost every routine is designed for a skin that stays stable. That skin doesn't exist.

Menstruation

Days 1–5

Oestrogen and progesterone are low. Skin can feel drier, more sensitive, more reactive.

Follicular phase pictogram

Follicular

Days 6–13

Oestrogen rises. Skin bounces back: more radiance, more resilience.

Ovulation phase pictogram

Ovulation

Days 14–16

Oestrogen peaks. Often the moment skin is at its brightest.

Luteal phase pictogram

Luteal

Days 17–28

Progesterone takes over. More sebum, and sometimes breakouts.

What about contraception?

If you take hormonal contraception, your cycle may be on pause. Your skin still has needs. And when you stop, it often has a lot to say: this is the moment many of us see acne come back.

Less fighting. More understanding.

Different phase. Different care.

Instead of correcting your skin, give it what it needs when it needs it. Soothe during your period, revive in the follicular phase, hydrate around ovulation and rebalance in the luteal phase. That's the whole idea behind Sézon.
