Dermatological health and skin rejuvenation
Medical Disclaimer
Topical and systemic compounds studied for skin health, anti-aging, and complexion improvement. Dermatological science has robust evidence for several interventions in this category.
Protocol Map
Compounds organized by evidence tier. Foundation compounds have the strongest clinical support. Emerging compounds show promise but lack robust human data.
Foundation
Gold standard topical anti-aging
Tretinoin (retinoic acid) is the most evidence-backed topical for photoaging, increasing collagen synthesis and accelerating cell turnover. Niacinamide (vitamin B3) reduces inflammation, improves barrier function, and addresses hyperpigmentation. Together they form the foundation of evidence-based skincare.
Copper peptide for collagen remodeling
Clinical studies show GHK-Cu improves skin density, elasticity, and firmness. Stimulates collagen and glycosaminoglycan synthesis. Comparable to tretinoin in some clinical endpoints with better tolerability.
Commonly Added
Hyperpigmentation treatment
The combination of hydroquinone (tyrosinase inhibitor) with tretinoin is the gold standard for melasma and post-inflammatory hyperpigmentation. Typically used in 8-12 week cycles under dermatological supervision.
Emerging
mTOR inhibition for skin aging
A pilot study showed topical rapamycin improved clinical markers of skin aging (reduced wrinkles, improved skin tone). Mechanism involves enhanced collagen production and reduced senescent cell burden. Larger trials are needed.
Cellular energy for skin repair
Topical NAD+ precursors (nicotinamide riboside, NMN) are being studied for skin photoprotection and cellular energy support. Niacinamide, the most studied form, already has robust clinical data for skin benefits.
Recommended Monitoring
Lab work and clinical assessments commonly recommended when pursuing this goal. Your provider will determine the appropriate testing schedule for your situation.
| Test | Frequency | Purpose |
|---|---|---|
| Clinical Skin Assessment | Baseline, then every 3 months | Track skin texture, tone, pigmentation, and fine lines |
| Standardized Photography | Baseline, then every 3 months | Objective documentation of treatment progress |
| Patch Test (new topicals) | Before starting any new topical compound | Screen for contact dermatitis or irritant reactions |
Lifestyle Foundations
Daily broad-spectrum SPF 30+ sunscreen is the single most impactful anti-aging intervention, preventing up to 80% of visible skin aging. Adequate hydration and a diet rich in antioxidants (vitamins C and E, polyphenols) support skin health from the inside. Sleep quality directly impacts skin barrier repair, which occurs primarily overnight. Avoiding smoking and excessive alcohol significantly reduces premature skin aging. Consistent use of evidence-based topicals (retinoids, vitamin C, niacinamide) provides cumulative benefit over months and years.
