3 Things That Truly Move the Needle for Skin Anti-Aging

Alexis argues that the skincare industry overcomplicates routines, and that the vast majority of skin aging is driven by UV damage. He asserts that no peptide, vitamin C serum, or trendy moisturizer can compensate for sun exposure. The retinoid is the active repair agent, and he prefers tretinoin because it's the most studied and 10–100x stronger than over-the-counter retinols, but he insists on customized dosing to avoid the irritation that causes many to quit. The barrier support is often overlooked; he recommends a simple, non-irritating cleanser (like an intimate gel) and a moisturizer that can double as sunscreen. This three-product regimen strips away the noise and delivers the highest return on investment. He emphasizes that consistency with these basics is far more important than chasing novel ingredients.

Alexis notes that even with sunscreen, some UV and infrared rays penetrate, and the cumulative effect over decades is what matters. He cites his Mediterranean environment where he avoids sun from 10am to 6pm, instead getting morning and late afternoon light. He also recounts crossing the Sahara with non-nano zinc oxide, but still used protective clothing. This protocol is about common sense, not sun phobia. He encourages mimicking grandparents' habits: avoiding midday sun, using shade, and wearing protective garments. He also clarifies that you can get safe sunlight exposure in the early morning and late evening even with SPF on.

Alexis explains that facial muscles have lifting and depressive roles. The platysma, a depressive muscle, tends to overcontract with age and stress, pulling the face downward, while lifting muscles like the zygomaticus are underused. He believes facial gymnastics can counteract this, though he admits it takes regular practice. For immediate relief, massaging the masseter and platysma insertion can reduce tension and prevent the gradual development of a down-turned expression. He also notes that everyone has natural asymmetry, but conscious effort to contract the weaker side can help. This is a low-cost, non-invasive approach, but it's not a substitute for medical treatments like fillers or lasers if structural changes are advanced.

He uses rapamycin for its well-known autophagy induction and potential longevity benefits, but acknowledges that chronic mTOR inhibition can impair immune function, making him vulnerable to seasonal infections. His solution is to temporarily replace rapamycin with spermidine, a polyamine that also promotes autophagy through a different mechanism (inhibition of EP300 acetyltransferase). He feels this is a safer way to maintain cellular cleanup during high-risk periods. This is a nuanced personal protocol, not a general recommendation. He emphasizes that he doesn't want to suppress his immune system when flu and colds are circulating.

Alexis is upfront that there is no robust data proving that exogenous NAD supplementation slows aging. However, he reasons that NAD declines with age and is critical for sirtuin activation, DNA repair, and energy metabolism. He monitors his own levels and uses both IV and subcutaneous routes to maintain them in a youthful range. He sees it as a risk-benefit decision based on mechanistic plausibility, not confirmed efficacy. This is part of his broader philosophy of being 'comfortable with some risk' when the safety profile is acceptable and the potential upside is high.

He combines the flavonoid quercetin intravenously with a short course of dasatinib, a tyrosine kinase inhibitor known to induce apoptosis in senescent cells. This is based on the 'hit-and-run' senolytic approach: a brief exposure to eliminate senescent cells, then a recovery period. He does this every 3 months, suggesting it's a recurring cycle. He acknowledges the experimental nature and the lack of human lifespan evidence, but he's comfortable because the combination has shown promise in animal studies and early human trials for reducing senescence markers. He monitors his health closely.

He uses exosomes derived from Muse stem cells, which are multi-lineage undifferentiated stress-enduring mesenchymal stem cells from umbilical cord. These exosomes are thought to carry regenerative signals and modulate immune senescence. He saw a measurable drop in GrimAge after treatments, but he stresses it's an N=1 and not a recommendation. He continues because he's seen no adverse effects and his biomarkers remain stable. He considers this a promising area, but one that demands rigorous tracking. He is planning to continue and gather more data on himself.

He uses peptides that are part of the Russian bioregulator tradition, such as epitalon (pineal peptide), thymalin (thymus), and pinealon (brain). He also uses others like epitalon for body composition goals. He emphasizes that peptides are not drugs and have been present in the body for millions of years, but overuse can cause issues. He monitors his biomarkers and adjusts. He doesn't recommend them to everyone, only if there's a specific need and under medical supervision. He shares his protocols on Instagram but stresses the experimental nature.

He highlights that diagnostics are the most expensive part of longevity protocols. He currently checks bloodwork, epigenetic age, telomeres, VO2 max, and body composition quarterly. He argues that more frequent monitoring could detect subtle changes earlier, allowing for quicker adjustments. He also mentions adding glycation clocks and more frequent imaging (MRI) to catch structural issues before they become clinical. He points to Brian Johnson's protocol as an example of extreme diagnostics. He believes this is where the money would go, not just therapies. He also emphasizes that standard biomarkers like blood pressure, ApoB, HbA1c, and CRP remain the most predictive for long-term health.

He explains that many patients can't tolerate commercial tretinoin due to irritation, especially those with atopic dermatitis or dry skin. By compounding, he can create micro-steps (e.g., 0.03%) and tailor the concentration to the individual. It takes 4-6 weeks for the skin to develop retinoic acid receptors and acclimate. This approach allows even those with reactive skin to eventually benefit from tretinoin's collagen-stimulating effects. He emphasizes that this must be done under medical supervision.

He uses rapamycin regularly for its potential longevity benefits, but is aware that chronic mTOR inhibition can increase infection risk. During flu season, he switches to spermidine, which he believes provides a milder autophagy boost without suppressing the immune system. This seasonal cycling is a personal adjustment based on his understanding of the mechanisms. He does not specify doses, but the concept is to temporarily avoid immune compromise when respiratory viruses are circulating.

He advises against natural soaps and alkaline cleansers, and instead favors products with lactic acid or citric acid, like those intended for baby skin. The intimate gel is designed for sensitive mucosa, making it ideal for the face. He has used this recommendation in his clinic for years (first mentioned in a previous podcast) and finds it works well alongside retinoids without causing dryness or stinging. It couples well with the need for a gentle, low-pH cleanse.

He stresses that this is an N=1 self-experiment, not a recommendation. He monitors his health parameters closely and has seen no adverse effects. The exosomes are derived from Muse cells, which are multi-lineage undifferentiated stress-enduring mesenchymal stem cells from umbilical cord, believed to be safer than other stem cell types. He continues the therapy because the epigenetic age reduction was significant and his biomarkers remain stable. He views this as a promising area but urges caution and rigorous monitoring.

He notes that the bulk of Brian Johnson's $2 million annual spending is on diagnostics, not therapies. He believes more frequent testing could detect subtle biomarker shifts earlier, allowing for quicker adjustments. He would also add glycation clocks and more frequent imaging (ultrasound every 6 months, MRI every 2 years) to catch structural issues before symptoms appear. This is a theoretical wishlist, not a recommendation for the average person, but it reflects his belief that data granularity is key to anti-aging.
