Skin Health and Anti-Aging Notes

Nov 2, 2025

Overview

Dr. Kirsten Singler, Clinical Director at Lee Regenerative and naturopathic doctor, discusses evidence-based approaches to skin health and anti-aging. The conversation covers topical treatments, key supplements, lifestyle factors, and emerging therapies for maintaining vitality and youthful appearance.

Topical Treatments for Skin

  • Estriol cream (estrogen number three) improves dermal thickness and collagen without systemic absorption risks.
  • Quicksilver brand combines estriol with hyaluronic acid; available over-the-counter for creepy skin areas.
  • Castor oil increases dermal thickness and provides deep moisture; primary drawback is thickness.
  • Prescription retinol (retinoic acid) prevents photo damage, reduces discoloration, and increases cellular turnover.
  • Start retinol with pea-sized amount at night on damp skin; build tolerance gradually over weeks.
  • Retinol causes initial sloughing; increases sun sensitivity requiring protective measures.
  • Niacinamide in sunscreen supports skin radiance and helps cells tolerate oxidative damage.
  • Recommended rotation: retinol at night, estriol/hyaluronic acid during day, castor oil once weekly.

Key Supplements for Skin Health

SupplementPrimary BenefitsDosage/Notes
AstaxanthinActs as internal sunscreen; reduces fine lines; improves moisture retention and skin barrier6 mg per day (capsule)
B VitaminsReduces discoloration, acne, rosacea; strengthens skin immunityB5 especially important for acne
CollagenImproves skin thickness, nail hardness, hair growthPowder scoop or from bone broth/gelatin
Vitamin CBuilds collagen; provides antioxidant protection from oxidative damageEssential for collagen synthesis
  • Collagen can be obtained from food sources: bone broth, chicken cartilage, homemade gelatin.
  • Type 1 collagen supports skin; Type 2 supports connective tissues, ligaments, and tendons.
  • High doses required; typically consumed as powder in smoothies or drinks.

Essential Anti-Aging Supplements

SupplementPrimary BenefitsDosage
MagnesiumPrevents dementia; improves bone density; reduces colon cancer risk; aids sleep300 mg per day
Vitamin D + K2Prevents osteoporosis; reduces dementia 40%; anti-cancer; K2 bonds calcium to bonesMonitor levels closely
CreatineIncreases skeletal muscle mass when combined with exercise5 g per day
CoQ10Protects heart and mitochondria; critical for statin users to prevent dementia200-600 mg per day
Alpha-Lipoic AcidNeuroregenerative; improves IQ; reduces cancer risk; regenerates kidneysDose varies
TurmericReduces dementia and cancer risk; anti-inflammatory alternative to NSAIDsDaily supplementation
RapamycinExtends healthspan; prescription only; promising animal study results1 pill weekly (prescription)
  • 90% of Americans are vitamin D deficient despite supplementation due to absorption variability.
  • Some individuals require injectable vitamin D; others hyper-absorb and risk toxicity.
  • Creatine requires exercise to show benefits; no effect without physical activity.
  • Rapamycin currently in clinical trials for periodontal disease; used off-label for anti-aging.

Lifestyle Factors

  • Hydrate with half body weight in ounces of water daily; dehydration causes gaunt, thin skin.
  • Smoking causes perioral wrinkles and damages skin radiance; no amount is safe.
  • Alcohol impairs liver detoxification; causes facial puffiness, inflammation, acne, and rosacea.
  • Stopping alcohol reduces water retention, improves sleep quality, and enhances mood and appearance.
  • Soil depletion means even healthy diets lack adequate minerals; supplementation often necessary.
  • Polyphenol-rich antioxidant diet supports skin health from inside out.

Aging Mechanisms

  • Aging involves cellular degradation: mitochondria breakdown, DNA damage, telomere shortening.
  • Reactive oxygen species (ROS) from sun exposure and normal energy production damage cells.
  • Inflammation markers (tumor necrosis factor, IL-6) accelerate cellular breakdown.
  • Sirtuin 1 and cell senescence affect healthy cell turnover and stem cell production.
  • Common age-related conditions: dementia, vision loss, osteoporosis, heart disease, cancer, fragility.

Clinical Observations

  • Patients using topical treatments with consistent supplementation show visible skin improvement.
  • Hair and nail growth serve as indicators of effective protein synthesis and collagen production.
  • Sleep quality directly correlates with skin appearance; poor sleep reflects in complexion.
  • Beverly Hills patients provide unique perspective comparing those with/without cosmetic procedures.
  • Natural glow comes from internal health rather than surgery alone.
