Enhancing Skin Health Through Omega-3 Fatty Acids and Antioxidant-Rich Diets: A Comprehensive Review Supported by Premium Doctors’ Medical Expertise
Bibliographic record
Abstract
Background: Skin health is an integrative marker of systemic well-being, and recent research increasingly recognizes nutrition as a modifiable determinant of skin physiology and aging. Among nutritional factors, omega-3 polyunsaturated fatty acids (PUFAs) and antioxidant-rich diets have received significant attention for their protective effects against inflammation, oxidative stress, and photodamage—key contributors to dermatological aging and disorders.Methods: This literature review systematically explores the scientific evidence on the roles of omega-3 fatty acids and dietary antioxidants in supporting and enhancing skin health. A total of 45 peer-reviewed articles published between 2015 and 2025 from databases including PubMed, Scopus, and Web of Science were analyzed.Results: Findings indicate that omega-3 fatty acids—primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—modulate inflammatory responses in the skin, reduce UV-induced damage, and improve skin barrier integrity. Antioxidants such as vitamins C and E, polyphenols, flavonoids, and carotenoids protect dermal structures from reactive oxygen species and support collagen preservation. A synergistic effect is evident when both omega-3 fatty acids and antioxidant-rich diets are combined, enhancing cutaneous repair, hydration, and elasticity while slowing extrinsic aging processes. Gaps remain in understanding precise dosages, bioavailability, and long-term dermatological outcomes.Conclusions: Omega-3 fatty acids and antioxidants represent a promising, non-invasive frontier in dermatology. Future research should focus on controlled clinical trials and nutrigenomic studies to develop targeted interventions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
