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
| Supplement | Primary Benefits | Dosage/Notes |
|---|
| Astaxanthin | Acts as internal sunscreen; reduces fine lines; improves moisture retention and skin barrier | 6 mg per day (capsule) |
| B Vitamins | Reduces discoloration, acne, rosacea; strengthens skin immunity | B5 especially important for acne |
| Collagen | Improves skin thickness, nail hardness, hair growth | Powder scoop or from bone broth/gelatin |
| Vitamin C | Builds collagen; provides antioxidant protection from oxidative damage | Essential 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
| Supplement | Primary Benefits | Dosage |
|---|
| Magnesium | Prevents dementia; improves bone density; reduces colon cancer risk; aids sleep | 300 mg per day |
| Vitamin D + K2 | Prevents osteoporosis; reduces dementia 40%; anti-cancer; K2 bonds calcium to bones | Monitor levels closely |
| Creatine | Increases skeletal muscle mass when combined with exercise | 5 g per day |
| CoQ10 | Protects heart and mitochondria; critical for statin users to prevent dementia | 200-600 mg per day |
| Alpha-Lipoic Acid | Neuroregenerative; improves IQ; reduces cancer risk; regenerates kidneys | Dose varies |
| Turmeric | Reduces dementia and cancer risk; anti-inflammatory alternative to NSAIDs | Daily supplementation |
| Rapamycin | Extends healthspan; prescription only; promising animal study results | 1 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.
