Reduction of Wrinkles 1

A clinical trial with more than 100 women aged between 45 and 65 years showed that the oral administration of 2.5 grams per day of the collagen peptides in Lova Naturals® significantly reduces wrinkles after 4 weeks and leads to a significantly higher skin pro-collagen type I and Elastin concentration.

  • Duration
  • Month 1

    Eye wrinkle volume significantly reduced by more than 7.2% (p<0.05). 1

  • Month 2

    Eye wrinkle volume significantly reduced 20.1% on average (p<0.01). A maximum reduction in eye wrinkle volume of 49.9% was achieved.1

    Pro-collagen type I and Elastin significantly increased by 65% and 18% respectively (p<0.01). 1

Higher Skin Elasticity 2

Another clinical trial containing 69 women aged between 35 and 55 years revealed that the collagen peptides in Lova Naturals® Beauty Repair leads to significantly higher skin elasticity – up to 15% - compared to placebo treatment. The effect could be measured after just 4 weeks of treatment and persisted after 8 weeks of consumption. Even after the test group stopped consuming Lova Naturals® Beauty Repair, the test group still showed higher skin elasticity levels than in the placebo treated group at 4 weeks.

  • Duration
  • Month 2

    Skin elasticity increased by 7% (p<0.05), with more pronounced effect on women ≥ 50 years. In Some women, a maximum increase of skin elasticity of up to 30% was observed. 2

Promoting Growth and Health of Fingernails 3

Many women suffer from cracked or chipped nails, nail peeling and nail roughness. A clinical trial published in 2017 showed a decrease of cracked and/or chipped nails just after 2 months of treatment, reaching a decrease of 42% after 6 months. Also, there was a statistically significant improvement in nail growth after 3 months of consuming the collagen peptides in Lova Naturals® Beauty Repair when compared to the control group.

  • Duration
  • Month 3

    Nail growth rate significantly improved 10% (p<0.05). 3

  • Month 6

    Nail growth rate increased 12% and to 15% after 4 week after the last intake (washout period). 3

    Broken Nails frequency decreased by 42%.3

    Brittle Nails: 64% participant showed a clinical global improvement, with 88% of participants showing clinical global improvement after 4-week washout period. 3

Improved Skin Surface Structure & Significant Decrease of Cellulite Score 4

A double blind, randomized, placebo controlled study with 105 women aged between 25 and 50 years shows that the daily oral intake of the collagen peptides in Lova Naturals® Beauty Repair significantly decreases the cellulite score. The effect was measured after 3 and 6 months of supplementation. The ingredient in Lova Naturals® Beauty Repair has a beneficial effect on the skin extracellular matrix and restores the normal structure of the dermis and subcutaneous tissue. There was also visible reduced waviness of the skin after 3 months, with more noticeable effects after 6 months.

  • Duration
  • Month 3

    Cellulite degree assessment (pinch test) score decreased by 5.3% for participants with a Body Mass Index (BMI) ≤ 25. 4

  • Month 6

    Cellulite degree assessment (pinch test) score decrease by about 9% for participants with a BMI ≤ 25. 4

    Skin surface profile (waviness) reduced significantly by 11.1% (p<0.05) for participants with a BMI ≤ 25. 4
