Polycystic Ovary Syndrome (PCOS) is a widely prevalent endocrine condition, and is known to affect a significant percentage of women of reproductive age. The definitions and diagnostic parameters for PCOS vary. The most accepted definition for PCOS is the presence of chronic anovulation and androgen excess. Women with the aforementioned conditions may also experience a host of other symptoms that extend beyond the traditional realms of reproductive and metabolic functions.
Many women with PCOS suffer with skin conditions that may be distressing and chronic. acne, hirsutism, and androgenic alopecia are some conditions that may be attributed to the effects of increased androgens. Other skin conditions such as acanthosis nigricans may also be seen in women with PCOS. Although these conditions may vary in their severity and presence, the internal profound hormonal imbalance and resistance state is the driving force for these conditions.Treatment for some of these skin conditions have been largely unsuccessful, and/or temporary. Achieving clear skin and long-term symptom relief requires a synchronized approach that combines comprehensive pcos treatment with the clinical expertise of a specialized skin doctor.
The Biological Engine: How Hyperandrogenism and Insulin Impact the Skin
To appropriate medical intervention for PCOS-related skin conditions, we must first understand the endocrinologic basis of these conditions. Skin conditions associated with PCOS are caused and worsened by increased levels of androgens as well as insulin and glucose.
1. The Role of Androgens on the Pilosebaceous Unit
- Testosterone and DHEA-S are some of the androgens produced in increased amounts by the ovaries and adrenal glands of women with PCOS.
- The pilosebaceous unit, containing the sebaceous gland and a follicle, is concentrated with androgen receptors and the enzyme 5-alpha reductase. When 5-alpha reductase acts on testosterone, it produces DHT. DHT binds to androgen receptors and stimulates the sebaceous gland to produce more sebum. When sebum production and skin turnover is increased, the follicle becomes obstructed and more susceptible to infection by normal skin flora, Cutibacterium acnes.
- Pilosebaceous units produce vellus hair that is thin and almost invisible. With the stimulation of androgens and 5-alpha reductase, the follicle becomes terminal, producing thick, pigmented hair. On the face and other androgenic areas, terminal hair is unwanted (hirsutism). However, on the scalp, miniaturization of the hair follicles leads to thinning of the hair.
2. The Insulin Resistance Connection
Between 70%-90% of women with PCOS have insulin resistance. When the body is insulin resistant, the pancreas creates more insulin to compensate.
There are two ways increased insulin levels affect PCOS symptoms. First, insulin helps the ovaries produce more androgens.
Second, insulin affects the production of Sex Hormone-Binding Globulin (SHBG). SHBG binds to androgens and other hormones. If the SHBG levels are low, androgens are unbound and not carried throughout the body.
When insulin levels are high, it affects the skin in another way. Hyperinsulinemia leads to the overproduction of keratin and glycosaminoglycan. This leads to acanthosis nigricans. The plaques of acanthosis nigricans are typically found on the armpits, groin and neck.
Internal Metabolic Protocols: Systemic PCOS Treatment
Insulin resistance is common among women with PCOS, regardless of their body mass index. Resistance to insulin ultimately leads to the pancreas producing more insulin. There are two ways that increased insulin levels worsen symptoms of hyperandrogenism. First, insulin stimulates the ovary to produce and release more androgens. Second, insulin levels affect LH and FSH levels, which in turn affect ovarian androgen production. Thus, one can see that ovarian and androgen production are affected by multiple factors including insulin.
Key Internal Therapies:
- While the dermatologic symptoms of PCOS can be treated with both topical and systemic therapies, it is also important to treat the metabolic and hormonal causes of these symptoms. Medications can be prescribed by an endocrinologist or other specialist to normalize hormone levels.
- Anti-androgens: Spironolactone is a medication that blocks androgens from acting on the skin. This medication helps to control oil production and growth of facial hair.
- Combined oral contraceptive pills (COCPs) help normalize and regulate menstrual bleeding and help control and reduce androgen levels.
- Inositol is a derivative of the B-vitamin group. There is a growing body of evidence that suggests that Myo-Inositol and D-Chiro-Inositol in the ratio of 40:1 improve insulin sensitivity and are helpful in the treatment of androgen excess. Metformin has similar benefits and is well tolerated by most patients.
External Clinical Therapies: The Role of the Skin Doctor
Current internal treatments may take months to reduce androgen levels, making direct treatment for current skin conditions and deep cystic acne necessary. A dermatologist provides a variety of minimally invasive procedures to address active skin concerns and prevents scarring.
Specialized Dermatological Interventions:
- Medical-Grade Topical Treatments: Dermatologists may also use other modalities to address acne such as the prescription of topical medications such as retinoids to accelerate cell turnover, along with other direct anti-androgens such as topical clascoterone, which stops DHT within the hair follicle.
- Chemical Peels: Chemical peels which contain salicylic acid or mandelic acid are especially helpful for inflamed acne, and glycolic acid peels are helpful for post-inflammatory hyperpigmentation.
- Laser Hair Removal: Permanent hair reduction for hirsutism is achieved through the use of Nd:YAG or Alexandrite lasers.
- Scar Therapy: For acne scar therapy, a combination of microneedling, Fractional CO2 laser therapy, and subcioning may be performed to promote new collagen synthesis.
Comparing Isolated Skincare vs. An Integrated Medical Protocol
| Clinical Metric | Isolated Over-the-Counter Care | Integrated Endocrine & Dermatological Protocol |
| Primary Target | Surface oil and superficial bacteria | Systemic androgen excess, insulin resistance, and follicular clogging |
| Long-Term Efficacy | Low (Acne recurs once topicals stop) | High (Resolves systemic triggers for lasting clarity) |
| Hair & Scalp Impact | None | Slows facial hirsutism and stabilizes scalp thinning |
| Risk of Scarring | High (Uncontrolled deep cystic inflammation) | Low (Early clinical extraction, peels, and anti-inflammatory control) |
Conclusion: Achieving Clear Skin Through Medical Synergy
While surgery or other physical treatments can alleviate the symptoms of PCOS that manifest on the skin, many patients are frustrated by the focus on superficial treatments for their PCOS symptoms.
For patients with acne, hirsutism or both, a collaborative team approach can be a powerful ally in their quest to have healthy functioning skin. The PCOS team, which generally consists of an endocrinologist or other physician and a skin care practitioner, can design a plan to alleviate acne and hirsutism. The PCOS team also has the training and skill to implement the various components of the plan, including procedures and surgeries.
There are also significant advances in medical and surgical treatments to reduce the appearance of acne scarring. Microneedling and the use of fractional CO2 lasers can stimulate collagen production and improve the appearance of acne scarring.
Finally, advances in hirsutism treatment have included the use of certain lasers to permanently remove the hair. The Nd:YAG and Alexandrite lasers, for example, target the melanin in coarse hairs.
