My skin has completely changed since having a baby

During pregnancy, oestrogen and progesterone are both significantly elevated. After birth — particularly after the delivery of the placenta — they drop sharply. This is one of the steepest hormonal shifts the body experiences outside of menopause.

Progesterone drops first and fastest. What's left is a relative oestrogen dominance that, for many post-natal people, persists for months — particularly if breastfeeding, which suppresses the normal recovery of progesterone.

The skin responds to this shift in multiple ways: dryness in areas that were previously normal, increased pigmentation (the 'pregnancy mask' that doesn't fully resolve), hair thinning, and in some cases new sensitivity or reactivity that wasn't present before.

When oestrogen is dominant relative to progesterone — as it often is post-natally — the skin can appear more emotionally reactive: flushing easily, developing hyperpigmentation in response to sun exposure, and fluctuating with mood or stress in ways that feel disproportionate.

Some people notice their skin is simultaneously dry and prone to congestion — which seems contradictory but reflects the mixed hormonal environment. The barrier is compromised by the progesterone withdrawal (dryness, sensitivity) while oestrogen can still drive melanin activity and inflammation.

Post-natal hormonal recovery isn't quick. For those who breastfeed, the full hormonal reset may not complete until months after weaning. This means skin that 'should be back to normal' by three months post-partum may genuinely still be operating in a disrupted hormonal environment.

Understanding this timeline changes the approach. Treatments designed for a stable hormonal baseline may not work — and may even irritate — during a period when the skin is fundamentally operating differently. Gentleness and supporting the barrier tend to be the more productive orientation while the hormonal picture stabilises.
