Collagen vs. Collagen Peptides: Which Supplement Is Better?
The article from Vogue compares collagen and collagen peptides supplements, examining their efficacy for skin health. Dermatologists Melanie Palm and Jenna Queller provide expert insights, noting that while collagen supplements are large molecules that may be broken down in the gut, collagen peptides are hydrolyzed and have more compelling evidence for modestly improving skin hydration and elasticity. The article emphasizes that supplements are adjuncts, not replacements, for a balanced diet, sunscreen, and retinoids. It also discusses topical collagen products, recommending ingredients like retinoids and peptides to stimulate collagen production, and highlights specific products such as Neocutis Bio Cream Firm, Paula's Choice Pro-Collagen Peptide Plumping Moisturizer, and Medik8 Liquid Peptides Advanced MP. For oral supplements, it advises seeking hydrolyzed collagen peptides from reputable manufacturers with third-party testing, and mentions brands like Vital Proteins, Ancient Nutrition, AlgaeCal, and Sparkle Wellness. The article notes that results may take eight to twelve weeks of consistent use, and collagen supplementation is a long-term commitment for maintaining skin health.
Key facts
- Collagen is a key protein in skin that provides scaffolding, keeping it firm and smooth.
- Collagen peptides are hydrolyzed collagen broken down into peptides, which may modestly improve skin hydration and elasticity.
- Dermatologist Melanie Palm says evidence on collagen peptides is more compelling than on collagen supplements.
- Dermatologist Jenna Queller says digestive system breaks down collagen into amino acids that can be used as building blocks for collagen synthesis.
- Both dermatologists stress that collagen peptide supplements are an adjunct, not a replacement for balanced diet, sunscreen, retinoids, or other evidence-based skincare.
- Topical collagen molecules are generally too large to penetrate deeply into the skin; hydrolyzed collagen is more likely to absorb but primarily supports hydration.
- Ingredients like retinoids and peptides can spur the body's own collagen production.
- Results from oral collagen peptides are typically measured after eight to twelve weeks of consistent use.
