A new review in the Journal of Cosmetic Dermatology finds that the evidence supporting collagen supplements for skin aging is methodologically flawed. While some studies show modest benefits, the authors argue that current data is biased and insufficient to recommend these products in clinical practice.
Dermatology and skincare experts say the most effective way to prevent wrinkles naturally is to protect and support collagen daily: wear SPF 30+ and sun-protective gear, guard the skin barrier with hydrating moisturizers rich in ceramides, use a retinoid at night and antioxidants like vitamin C during the day, and nourish from within with sufficient protein and collagen supplements. Add routine facial massage for improved circulation, prioritize restful sleep (magnesium can help), and sleep on a silk pillowcase to minimize creasing. The guidance emphasizes fresh vitamin C serums and a holistic routine over chasing quick fixes.
A HuffPost Shopping piece explains polydeoxyribonucleotide (PDRN), a salmon-sperm–derived DNA ingredient touted to boost collagen and hydration to reduce wrinkles. It profiles popular Korean PDRN products—from Iope’s PDRN Caffeine Shot serum to Medicube’s five-peptide formulas and VT Cosmetics’ PDRN 100 Essence—along with Rejuran Turnover ampoule and other novel formulations, while noting plant-based vegan PDRN options and the experts’ caveats about endorsements.
Gelatin-based, low-calorie desserts are highlighted as a way to support gut health, joint strength and aging due to the amino acids in collagen. Gelatin can help skin and cartilage, aid gut lining and calcium absorption via lysine, and may reduce inflammation with glycine. The dessert is low in calories (about 10 per tablespoon) and provides roughly 6 g protein, 2 g sugar and no fat; NIH guidance suggests 5–15 g daily if taken as a supplement for up to six months, though human evidence is still limited and much of the data comes from animal studies.
A large umbrella review of 113 clinical trials (nearly 8,000 participants) finds collagen supplements can modestly improve skin hydration and elasticity, joint pain (notably osteoarthritis), and muscle health, especially with hydrolyzed peptides and consistent use. However, effects vary by product, dose, and study quality, and many trials were small, short, or methodologically limited, making long-term conclusions uncertain. More standardized, rigorous research is needed to confirm which products and regimens are most beneficial.
Dietitian Josie Porter warns most supplements lack solid evidence and FDA oversight, so she uses only three evidence-backed ones: vitamin D in darker months, omega-3s when she hasn’t eaten oily fish, and collagen for tendon healing and skin health; she emphasizes choosing third-party-tested products and notes that whole foods often beat supplements for omega-3 benefits.
The largest umbrella review of collagen research (nearly 8,000 participants across 113 randomized trials) finds collagen supplements can improve skin hydration and elasticity and reduce osteoarthritis pain with longer use; modest improvements in muscle and tendon structure; little evidence for enhanced athletic performance or recovery; mixed or inconclusive results for metabolic and dental health; overall, collagen may support healthy aging but is not a quick fix for sports performance, and more high-quality trials are needed.
Collagen naturally declines with age, starting in your 20s and accelerating in later decades, and is further degraded by sun exposure, pollution, smoking, and high sugar intake. To support it, commit to daily SPF 30+, use retinoids, antioxidants, and peptides, and favor vitamin C–rich foods to aid collagen formation; note that topical collagen cannot penetrate deeply. Oral collagen supplements (like Verisol) may improve skin quality for some people, but results vary. For deeper results, dermatology treatments such as chemical peels, lasers, microneedling (often with PRP), radiofrequency or ultrasound devices, and biostimulating fillers can stimulate new collagen. A combination of sun protection, effective actives, nutrition, and appropriate in-office procedures offers the best path to firmer, more youthful-looking skin.
Vogue Beauty highlights eight key ingredients—retinoids, vitamin C, peptides, niacinamide, growth factors, hyaluronic acid, ceramides, and sunscreen—that actively protect and support collagen by boosting production, reducing breakdown, improving hydration, and fortifying the skin barrier, while noting potential irritation and the need for sun protection.
Five dermatologists say collagen supplements aren’t a miracle cure for skin: while some evidence hints at skin-health benefits and joint support, oral collagen may not directly deposit collagen in the skin, and results are generally modest at best. Benefits depend on consistent use and individual biology, and supplements should complement—not replace—a solid skincare routine, SPF, and a healthy diet. Choose well‑formulated brands and be mindful of additions like biotin and animal-sourced ingredients, especially if you have vegan or thyroid considerations.
A Liverpool-led study of a 66-million-year-old Edmontosaurus sacrum detected remnants of collagen and the amino acid hydroxyproline in a remarkably preserved fossil, using multiple analytical methods to rule out contamination. The findings suggest some original biomolecules can persist for tens of millions of years, offering new clues about dinosaur biology and evolution beyond bone structure.
Researchers analyzing a remarkably preserved Edmontosaurus sacrum detected remnants of endogenous collagen and related amino acids in a 66-million-year-old fossil, providing strong evidence against the idea that original biomolecules are always destroyed over deep time and potentially enabling new insights into dinosaur evolution and biology.
Magnesium and creatine emerge as the most evidence-backed menopause supplements, with magnesium aiding sleep and mood (not hot flashes) and creatine boosting strength and possibly brain function during perimenopause; collagen may modestly improve bone density and joint comfort, while lion’s mane has limited human data and largely non-menopausal studies. Overall, evidence is mixed and often not menopause-specific, product quality varies, and more research is needed. In the meantime, exercise, sleep, nutrition, and stress management remain the best long-term strategies.
Collagen makes up about 75% of the skin’s dry weight and begins to decline around age 25 (roughly 1% per year, with faster loss after menopause due to lower estrogen). Early signs include reduced firmness and sagging, drier skin, more noticeable wrinkles, less fullness, and subtle changes to facial shape. While collagen loss isn’t entirely preventable, you can slow it by protecting skin from sun, getting enough rest and managing stress, exercising, and eating a balanced diet rich in protein and nutrients. Use collagen-boosting actives (peptides, glycosaminoglycans, hyaluronic acid, vitamin C, niacinamide) and consider retinoids to stimulate your skin’s own collagen production. Topical collagen creams may improve surface texture but don’t prevent deep loss; a dermatologist can tailor a plan.
A dermatologist says the simplest way to slow collagen loss as we age is to make sunscreen a daily habit, since UV light damages collagen and accelerates aging. Use broad-spectrum SPF 30 or higher (50 SPF if you’ll be outdoors for long), apply enough to cover all exposed skin, and reapply regularly, with shade and UPF clothing as extra protection. After establishing sunscreen, you can support collagen further with ingredients like peptides and vitamin C, along with a balanced diet rich in amino acids, antioxidants and minerals to help maintain skin structure and youthful plumpness.
