Adult female hormonal acne is recognised as a distinct subtype of acne that differs from teenage acne or classic acne vulgaris, not only in its underlying causes but also in its presentation and persistence. It typically affects women over the age of 25 and may either continue from adolescence or appear for the first time in adulthood. Unlike adolescent acne, which often improves with age, hormonal acne can last for many years, sometimes persisting until the post-menopausal period.
Epidemiological studies show that the majority of adult acne patients are women, with an average age of around 35 years. Up to 5% of women between the ages of 40 and 49 may still experience active acne, underscoring its chronic and often frustrating nature. Beyond its physical effects, hormonal acne can also affect emotional well-being, self-confidence and quality of life.
Drawing on more than a decade of clinical experience treating thousands of acne patients across a wide spectrum of severity, we present a real-world case study of a female patient with hormonal acne, outlining her diagnosis, treatment plan, and outcomes.
CA is a 36-year-old female human resource manager who has been experiencing worsening acne since her mid-20s. Her breakouts clearly follow a hormonal pattern, flaring more severely in the week before her menstrual cycle. She reports a history of adolescent acne treated with a course of oral isotretinoin, which provided temporary clearance. In recent years, she has been prescribed courses of oral antibiotics and topical retinoids, but these offered only short-term relief. She is reluctant to restart oral isotretinoin therapy.
CA expresses frustration that she continues to suffer from acne in adulthood and is especially concerned about post-acne scarring. She is otherwise healthy, with no significant medical history, and is not on long-term medications. Family history reveals that both her siblings had acne during adolescence, but their symptoms did not persist into adulthood.
Lifestyle factors play a role: CA is a smoker and notes that stress, certain cosmetic products, and dietary triggers tend to worsen her acne flares.
Physical examination revealed a combination of inflammatory papules, pustules, and comedones along the cheeks, jawline and upper neck, with one acne nodule present. Evidence of post-inflammatory hyperpigmentation, erythema, and atrophic acne scarring was also noted. Importantly, there were no signs of hirsutism (male-pattern hair growth), which may otherwise suggest an underlying endocrine disorder such as polycystic ovarian syndrome (PCOS).
Using the Adult Female Acne Scoring Tool (AFAST), CA’s presentation was graded as Moderate, based on the type and distribution of acneiform lesions across the face and jawline.
Score 1: Facial Acne Severity
| Score | Severity | Features |
| 0 | No lesions | No active acne lesions; may show residual pigmentation or erythema |
| 1 | Almost none | Few open/closed comedones, few papules |
| 2 | Mild | < 50% of face involved; few comedones, papules, pustules |
| 3 | Moderate | > 50% of face involved; numerous comedones, papules, pustules, and up to one nodule |
| 4 | Severe | Entire face involved; numerous comedones, papules, pustules, occasional nodules |
| 5 | Very severe | Very inflamed entire face, with multiple nodules |
Score 2: Jawline Acne Severity
| Score | Severity | Features |
| 0 | None | No active lesions; may show erythema or post-inflammatory hyperpigmentation |
| 1 | Rare | Rare papules, pustules, or comedones |
| 2 | Few | Few papules/pustules/comedones; < 25% of area involved; nodule/cyst may be present |
| 3 | Numerous | Numerous papules/pustules/comedones; ≥ 25% of area involved; ≥ 2 nodules/cysts may be present |
Moderate adult female acne associated with scarring
The diagnosis was made based on CA’s history, clinical presentation, and examination findings. Her acne was graded as moderate using the Adult Female Acne Scoring Tool (AFAST), with evidence of both inflammatory lesions and post-acne scarring.
Differential diagnoses were considered:
Thus, the clinical picture was most consistent with moderate adult female hormonal acne with post-inflammatory hyperpigmentation and atrophic scarring.
Given CA’s long-standing acne, its moderate severity, and her history of inadequate response to both oral antibiotics and topical therapies, a tailored management plan was discussed. The focus was on addressing the hormonal influence driving her breakouts, while simultaneously targeting inflammation, comedones, and scarring.
This multi-pronged plan aimed to provide both immediate acne control and long-term skin health, while respecting CA’s preferences and safety considerations.
CA was reviewed at monthly intervals to monitor her acne, treatment response, and any side effects from therapy.
The management of adult female acne requires a holistic, individualised approach, as this condition often persists for years and significantly affects quality of life. Unlike adolescent acne, adult female acne tends to be inflammatory, deep-seated, and localised to the lower face, chin and jawline. It is commonly influenced by hormonal fluctuations, stress and lifestyle factors, which makes long-term strategies essential.
This case highlights that success in adult female hormonal acne is best achieved through a personalised, layered treatment strategy that balances efficacy, safety, and long-term maintenance.
CA’s journey highlights how adult female hormonal acne can persist despite standard therapies and significantly affect confidence and quality of life. By tailoring her treatment to address the hormonal component with spironolactone, while supporting her skin with retinoids, lifestyle adjustments, and regular follow-up, we achieved steady improvement and long-term control. Within six months, she experienced a marked reduction in breakouts, fading of scars and pigmentation, and regained confidence in her appearance. This case underscores the value of a personalised, holistic approach that balances efficacy, safety, and patient preference in achieving lasting results.
