Beyond Sunblock: The MD Physician's Approach to Anti-Aging and Skin Resilience
By Susan F. Lin, M.D. | Physician | Reviewed: June 2026
Quick Answer
Sunblock is necessary but not sufficient. Photoaging accumulates from cumulative UV + visible light + infrared + free-radical damage. A physician-led anti-aging strategy combines: (1) daily broad-spectrum SPF; (2) topical antioxidants (stabilized vitamin C, vitamin E, ferulic acid); (3) growth-factor signaling via stem-cell-derived cytokines (MD Stem Cell Factor 55™); (4) barrier resilience (ceramides, niacinamide).
