Collagen Peptides Cut Wrinkles by 20% in Women Over 45

Quick Summary: A 2014 study tested if taking a special type of collagen supplement called Verisol® could fight skin aging. Women aged 45-65 who took 2.5 grams daily saw their eye wrinkles shrink by 20% after 8 weeks, with benefits lasting even a month after stopping. The supplement also boosted key skin proteins that keep skin firm and elastic.

What the Research Found

This double-blind study—meaning neither participants nor researchers knew who got the real supplement—showed clear skin benefits from Verisol® bioactive collagen peptides (BCP). Here's what happened:

Wrinkle Reduction: Eye wrinkles dropped by 20% after 4 weeks and stayed that way at 8 weeks. Even 4 weeks after stopping, the improvement held strong (backed by stats showing it wasn't just chance).
Skin Protein Boost: In skin samples, procollagen I (a building block for collagen) jumped 65%, elastin (which gives skin bounce) rose 18%, and fibrillin (which helps skin structure) increased 6%—though the last one wasn't statistically significant.
Long-Term Perk: The effects didn't fade right away, suggesting the supplement helps rebuild skin from the inside out.

These changes were measured with precise tools like 3D imaging for wrinkles and biopsies for proteins, proving real improvements over a fake pill (placebo).

Study Details

Who Was Studied: 114 healthy women aged 45-65, split evenly into two groups of 57. This age group often deals with visible aging signs like wrinkles around the eyes. (Note: All were women; results may differ for men.)
How Long: 8 weeks of daily intake, with check-ins at the start, 4 weeks, 8 weeks, and a 4-week follow-up after stopping to see if benefits lasted.
What They Took: 2.5 grams of Verisol® BCP powder mixed in water or juice once a day. It looked and tasted like the placebo to keep the study fair.

What This Means For You

If you're a woman in your 40s, 50s, or 60s noticing crow's feet or sagging skin, this study points to an easy option: a low-dose collagen supplement like Verisol® might smooth wrinkles without creams or procedures. Start with 2.5 grams daily for at least 8 weeks to see changes—mix it into your morning routine. It could mean firmer, more youthful skin by supporting your body's natural collagen production. Always chat with a doctor before starting, especially if you have allergies or health conditions. Remember, this is specific to Verisol®; not all collagen supplements work the same.

Study Limitations

No study is perfect—here's what to keep in mind:
- Brand-Specific: Results are for Verisol® only; other collagens might not deliver the same wrinkle-fighting power.
- Women Only: It focused on middle-aged women, so we don't know if men or younger/older folks get the same benefits.
- Short-Term: Just 8 weeks, with only a 4-week check after; long-term effects need more research.
- Smaller Skin Tests: Only a subset had biopsies, which might limit how solid the protein boost findings are.
- Funding Note: The collagen maker (GELITA AG) funded it, so independent studies would add trust.

This research is promising but preliminary—pair it with sunscreen, hydration, and a healthy diet for best skin health.

Key Findings

The study demonstrated that daily oral intake of 2.5 g of bioactive collagen peptides (BCP, Verisol®) significantly reduced eye wrinkle volume by 20% after 4 and 8 weeks compared to placebo. This effect persisted for 4 weeks post-treatment. BCP also increased dermal matrix proteins: procollagen I by 65% and elastin by 18% (both p < 0.05), with a non-significant 6% rise in fibrillin.

Study Design

This was a double-blind, placebo-controlled clinical trial involving 114 women aged 45–65 years. Participants were randomized into two groups (57 per group). Skin wrinkles were measured objectively using a 3D skin surface imaging system at baseline, 4 weeks, 8 weeks, and 4 weeks post-treatment. A subgroup underwent suction blister biopsies to assess dermal protein synthesis at baseline and 8 weeks.

Dosage & Administration

Subjects received 2.5 g of BCP or placebo once daily for 8 weeks. The supplement was administered in powdered form, dissolved in water or juice, and matched for appearance and taste. Compliance was monitored via returned packaging.

Results & Efficacy

Wrinkle Volume: Reduced by 20% in the BCP group after 4 and 8 weeks (p < 0.05 vs. placebo). The effect remained significant 4 weeks post-treatment (p < 0.05).
Procollagen I: Increased by 65% in BCP-treated skin biopsies after 8 weeks (p < 0.05).
Elastin: Levels rose by 18% in the BCP group (p < 0.05).
Fibrillin: Showed a 6% increase with BCP but lacked statistical significance.
Regression Phase: Benefits persisted after discontinuation, suggesting sustained dermal remodeling.

Limitations

Funding Bias: Sponsored by the manufacturer (GELITA AG), potentially influencing outcomes.
Population Specificity: Only middle-aged women were studied; results may not apply to men or other age groups.
Short Duration: 8-week intervention with limited post-treatment follow-up (4 weeks).
Subgroup Size: Biopsy analysis included a smaller subset, reducing statistical power for dermal protein measurements.
Mechanistic Gaps: The study did not explore molecular pathways or collagen absorption mechanisms.

Clinical Relevance

For middle-aged women seeking non-invasive skin aging interventions, this study suggests that daily 2.5 g BCP (Verisol®) may reduce wrinkles and enhance dermal protein synthesis. The observed effects (e.g., 20% wrinkle reduction) align with consumer expectations for collagen supplements. However, the lack of diversity in the sample and industry funding highlight the need for independent, longer-term trials across broader demographics. Practitioners should consider these findings as preliminary evidence for collagen’s skin benefits, emphasizing consistent use for optimal results.
