Hormonal acne: what are we talking about?

Hormonal acne is a form of acne directly linked to fluctuations in sex hormones, notably androgens (testosterone, DHT). These hormones stimulate sebaceous glands and increase sebum production, which promotes pore obstruction and the development of Cutibacterium acnes. It mainly affects adult women aged 20 to 40, often localised on the lower face: jaw, chin and neck.

How to recognise hormonal acne?

Hormonal acne is distinguished from other acne forms by several characteristics. It appears mainly on the lower face (jaw, chin, lower cheeks) rather than forehead or nose. It follows a cyclic rhythm, systematically worsening in the week before periods. It often manifests as deep painful cysts rather than simple blackheads. It persists into adulthood even if puberty has long ended.

The hormonal mechanisms at play

Oestrogens and progesterone vary throughout the menstrual cycle. In the luteal phase (after ovulation), progesterone increases and can indirectly stimulate sebum production. At the same time, oestrogen levels drop slightly, reducing their protective effect on the skin. This transient imbalance creates fertile ground for acne breakouts. Chronic stress aggravates this phenomenon via cortisol, which also stimulates sebaceous glands.

Natural daily approach for hormonal acne

Facing hormonal acne, a topical-only approach is often insufficient. It is essential to act simultaneously on the skin and on internal factors. Topically, favour gentle anti-inflammatory and antibacterial actives: lactoferrin, fermented white willow, probiotics. Avoid aggressive products that weaken the skin barrier and amplify inflammation. Internally, certain dietary supplements can support hormonal balance and reduce systemic inflammation. At Zactigis, SkinCTRL combines an external action and an internal support formulated for skin prone to imperfections of hormonal origin.

The role of the microbiome in hormonal acne

An often neglected aspect of hormonal acne is its link with the skin microbiome. Hormonal fluctuations disturb the balance of the skin flora, promoting Cutibacterium acnes proliferation at the expense of beneficial bacteria. That is why a probiotic approach — by supporting the skin's microbial diversity — can have a significant impact on the frequency and intensity of hormonal breakouts. Integrating probiotic actives into your routine is one of the most modern and effective approaches to managing this type of acne long-term.
