Skin Health Guide: Dr. Andrew Huberman on Acne & Rosacea
Managing Acne Through Diet and Hormones
Acne affects up to 90% of young people and remains a persistent challenge for many adults. While often viewed as merely a cosmetic concern, its impact on mental health and social interactions can be profound. The good news is that understanding the biochemical pathways behind acne reveals clear strategies for management.
At its core, acne develops from the accumulation of sebum (oil) in hair follicles. Two major pathways drive this process: hormonal influences and dietary factors. The androgenic effects of testosterone, present in both males and females, can increase sebum production and cause growth of hair follicles, leading to those characteristic bumps and cysts.
The dietary pathway is equally significant but often overlooked. Insulin, which rises in response to food intake, activates mTOR (mammalian target of rapamycin), a cellular growth signal. When insulin levels spike excessively due to high-glycemic foods or overeating, mTOR activation can enhance androgen receptor sensitivity, creating a feedback loop that increases sebum production.
Dairy products present an interesting case study in acne management. Contrary to popular belief, low-fat dairy may actually worsen acne compared to full-fat options. The emulsifiers in low-fat dairy products can trigger larger insulin spikes, potentially exacerbating skin issues. This illustrates why simplistic “low-fat” approaches might backfire.
The solution lies in strategic dietary choices. Minimize processed foods, control portion sizes, and maintain stable blood sugar levels. While intermittent fasting can help regulate insulin response in adults, it may not be appropriate for adolescents who need consistent nutrients for growth.
The relationship between whey protein and acne deserves special attention. While whey offers excellent amino acid profiles for muscle building, some individuals find it triggers breakouts. The key is personal experimentation – monitor your skin’s response and adjust accordingly.

Remember that inflammation serves as a common denominator in these pathways. High-glycemic foods combined with saturated fats (think French fries with milkshakes) create the perfect storm for inflammatory responses that can manifest as acne. By understanding these mechanisms, we can make informed choices about our diet and lifestyle to support clearer skin.
Managing Acne With Cleansing and Skincare Tips
Managing acne effectively requires a delicate balance between proper cleansing and avoiding over-treatment. While many people instinctively reach for harsh cleansers and aggressive washing routines, dermatologists consistently emphasize the importance of gentle skincare practices.
The foundation of proper acne management starts with lifestyle factors: adequate sleep, stress reduction, and a healthy gut microbiome. However, the most counterintuitive aspect might be the cleansing routine itself. Huberman notes that excessive washing can disrupt the skin’s natural microbiome, potentially leading to increased inflammation and even fungal infections.
Instead, aim for cleansing two to three times daily using a gentle, unscented cleanser. Temperature matters – use lukewarm water rather than hot, as extreme temperatures can exacerbate inflammation. Simple, fragrance-free products like basic bar soaps or gentle cleansers like Cetaphil often prove most effective.
Salicylic acid, from the same family as aspirin, can be a powerful ally in treating acne. It works by reducing keratinocyte adhesion, preventing pore blockages that lead to breakouts. However, it’s crucial to apply these products only on thoroughly cleansed skin.
Perhaps the most critical advice from dermatologists concerns pimple popping. While the urge to extract might be strong, this practice can trigger the release of matrix metalloproteases – enzymes that degrade the extracellular matrix and create permanent indentation scars. Instead of popping, consider using corticosteroid cream to reduce inflammation and redness.
For severe cases, dietary modifications can yield surprising results. Many patients experience significant improvement by eliminating highly processed foods and reducing dairy consumption, while increasing their intake of anti-inflammatory foods like fruits, vegetables, and quality protein sources from meat, fish, and eggs.
These principles of gentle cleansing, proper skincare, and dietary modification form the cornerstone of effective acne management. When combined with professional medical guidance when necessary, they offer a comprehensive approach to treating this common but distressing condition.
Understanding and Treating Rosacea
Rosacea, a condition characterized by facial reddening, affects people with varying degrees of severity. While some experience mild symptoms, others face persistent and distressing manifestations that can be exacerbated by emotional states like embarrassment.
The foundation of treating rosacea lies in addressing systemic inflammation through lifestyle modifications. A low-inflammation, low-glycemic diet serves as the cornerstone of treatment, complemented by adequate sleep and careful attention to alcohol consumption. In fact, many individuals who completely eliminate alcohol witness a dramatic reduction or complete resolution of their rosacea symptoms.
The skin care routine for managing rosacea follows similar principles to general skin health maintenance. Lukewarm water should be used for cleansing, avoiding temperature extremes that might trigger flare-ups. A gentle, fragrance-free cleanser forms the basis of daily care, while regular application of mineral-based sunscreen provides essential protection against UV-induced inflammation.
Moisture retention plays a crucial role in managing rosacea. Hyaluronic acid or gentle moisturizing creams help maintain skin barrier function without causing irritation. While premium products flood the market, effectiveness doesn’t necessarily correlate with price point. The key lies in selecting products that meet specific criteria rather than falling for marketing claims or luxurious packaging.
Additional interventions can enhance treatment outcomes. Nicotinamide (also known as niacinamide) shows promise, whether applied topically or taken orally at 2,500mg daily. Licorice root-based topical treatments may also offer benefits, though research in this area continues to evolve.
Certain triggers should be avoided to prevent flare-ups. Spicy foods, strong astringents, and anything that increases skin temperature can provoke symptoms. While this might require lifestyle adjustments, understanding and avoiding these triggers often leads to better management of the condition.
The complexity of rosacea demands a multi-faceted approach. By addressing both internal factors through diet and lifestyle modifications, and external factors through appropriate skincare, many individuals can achieve significant improvement in their symptoms. The key lies in consistency and patience with the chosen treatment protocol.
Types of Rosacea and Treatments
Rosacea is a complex skin condition that manifests in four distinct types, each requiring a nuanced approach to treatment. While many cases respond well to basic lifestyle modifications, others demand more specialized interventions.
Understanding the various triggers is crucial for managing rosacea effectively. Temperature plays a significant role – both in terms of spicy foods and hot beverages. The key is moderation and awareness of how these factors affect your particular condition.
Environmental factors and skincare habits can significantly impact rosacea’s severity. One common mistake is over-cleansing, which can exacerbate symptoms. While proper hygiene is essential, aggressive cleansing can compromise the skin’s natural barrier and worsen rosacea symptoms.
Post-exercise hygiene deserves special attention. After any workout – whether it’s weight training, cardio, or activities like jiu-jitsu – immediate cleansing becomes crucial. Gyms are breeding grounds for bacteria, both on equipment and from other people’s sweat. A prompt shower with gentle cleanser isn’t just good etiquette; it’s essential for skin health.
For particularly stubborn cases that persist despite lifestyle adjustments and medical treatments, additional interventions may be necessary. Some individuals develop angiomas or accumulated blood vessels near the skin’s surface, either as part of their rosacea or as a consequence of treatment.
In these cases, pulse dye laser treatment performed by a qualified dermatologist can be effective. This specialized treatment uses specific wavelengths of light to penetrate the skin’s superficial layers and target problematic blood vessels. The precision of different light wavelengths allows for treatment at various skin depths, making it a versatile option for addressing persistent vascular issues associated with rosacea.
Understanding Psoriasis and Immune System Treatment
For more than eight decades, the medical community believed psoriasis was simply an overproduction of skin cells without a clear understanding of its root cause. However, modern dermatological research has revealed a more complex picture: psoriasis is fundamentally tied to immune system dysfunction.
This revelation has transformed our approach to treating this chronic skin condition. Rather than focusing solely on managing skin cell production, contemporary treatments target the immune system’s response. The key breakthrough has been the development of prescription medications that specifically target interleukins—particularly IL-17 and IL-23—which are immune system components directly involved in psoriasis.
These targeted treatments have shown remarkable effectiveness. While many people naturally gravitate toward behavioral modifications, nutritional approaches, or supplementation—all valuable tools in their own right—it’s important to acknowledge the significant advances in pharmaceutical solutions. These medications can precisely modulate immune system activation without compromising our natural defenses against infections.
At its core, psoriasis represents an autoimmune condition where the body essentially turns against itself, resulting in the characteristic itchy, scaly patches that can appear on the scalp and other areas of the body. Understanding this immune system connection has revolutionized treatment approaches and opened new avenues for managing this challenging condition.
The skin, our largest organ, demonstrates the intricate connections between various bodily systems. Its relationship with the immune system, as exemplified in conditions like psoriasis, highlights the complexity of human biology and the importance of taking a comprehensive approach to skin health.
This understanding has profound implications for treatment strategies. By viewing psoriasis through the lens of immune system regulation rather than merely as a skin cell production issue, we can better target the root cause of the condition. This shift in perspective represents one of the most significant advances in dermatological understanding in recent decades.
