For decades, hormone therapy (HT) faced unwarranted backlash, driven by overly cautious FDA warnings that scared many women away from treatments that could alleviate debilitating menopausal symptoms. The FDA’s “black box” warning, once a significant barrier to access, has now been reversed, acknowledging that earlier fears were largely overstated based on outdated research. This shift is poised to increase HT adoption, as both physicians and pharmacists become more willing to prescribe and dispense these medications.
But beyond symptom relief, HT has profound effects on skin health—effects that are now being more fully understood. Hormones directly influence collagen production, hydration, and barrier function, making HT a significant factor in maintaining youthful, resilient skin.
What Is Hormone Therapy?
Hormone therapy involves restoring declining hormone levels, typically starting with estrogen for women in perimenopause or menopause. Estrogen receptors are widespread throughout the body, impacting bone health, cognitive function, and crucially, skin integrity. The most common form is estradiol, taken orally, vaginally, or transdermally (patches, gels, sprays). Transdermal delivery is preferred by many physicians because it bypasses liver processing, reducing the risk of blood clots.
To protect the uterine lining, estrogen is often combined with progesterone or a synthetic progestin, unless a woman has had a hysterectomy. Progesterone also offers mood and sleep benefits, while testosterone, though historically restricted, is now recognized as potentially helpful for low libido, muscle mass, and overall well-being. Testosterone is typically administered as a transdermal cream to allow for dosage adjustments.
The Controversy: Why Was HT So Feared?
The fear surrounding HT originated from the 2002 Women’s Health Initiative study, which linked it to increased risks of breast cancer, heart disease, and stroke. However, the study’s participants were older than the typical HT user, often with pre-existing health conditions, and used hormone formulations different from those prescribed today. Many experts now believe the findings were overstated or irrelevant to women initiating HT around menopause.
Despite this, the FDA implemented a black box warning that lingered for years, deterring countless women from seeking treatment. In November 2025, the FDA reversed course, removing the warning in recognition of updated data and a growing consensus among medical professionals.
How HT Affects Your Skin: A Deep Dive
Hormones profoundly impact skin at a cellular level. Estrogen, progesterone, and testosterone interact with receptors in the epidermis, dermis, sebaceous glands, and pigment pathways. Declining estrogen levels lead to reduced collagen production, impaired hydration, weakened barrier function, and slower wound healing.
Estrogen therapy reverses these effects by boosting collagen synthesis, improving hydration through increased hyaluronic acid and ceramide production, and strengthening the skin barrier. Studies show that HT can improve skin thickness, elasticity, and immune function. However, estrogen can also stimulate melanocytes, potentially leading to melasma (dark patches), particularly with sun exposure.
Progesterone therapy can subtly increase sebum production, which may improve barrier function but also contribute to acne in some individuals. Its calming effects can also indirectly benefit skin health by promoting better sleep.
Testosterone therapy, while less common, can enhance skin thickness and elasticity but may also cause acne due to increased oil gland activity.
Skincare Strategies for Women on Hormone Therapy
Given the potential side effects, a strategic skincare approach is crucial.
-
Melasma Prevention: Mineral sunscreens with zinc or titanium dioxide are essential, along with tinted formulas that block visible light. Brightening ingredients like vitamin C, azelaic acid, and tranexamic acid can help manage pigmentation. Professional treatments like chemical peels and targeted lasers (V Beam, PicoWay) can also be effective.
-
Hormonal Acne Control: Adjusting hormone dosage or delivery method may be the first step. Azelaic acid and retinoids can help manage breakouts, while medicated sulfur washes can further reduce inflammation.
The key takeaway is that hormone therapy’s effects on skin are complex and individualized. By understanding these interactions and adopting a proactive skincare routine, women can maximize the benefits while mitigating potential drawbacks.
Ultimately, the reversal of the FDA’s black box warning marks a turning point in women’s health, enabling more informed decisions and access to treatments that can significantly improve both overall well-being and skin health.
