THE SCIENCE

Marine collagen supports healthy skin

A study by Eskelinin et al (1992) demonstrated in a double blind placebo controlled trial with female subjects aged from 40 – 60 years that epidermal thickening from 0.11mm to 0.29mm and dermal thickening from 0.74 mm to 1.39 mm could be achieved after a treatment of 500mg /day of marine protein over 90 days. Skin elasticity also increased from 43% to 73%.

This research has been able to quantify, using VAS (Visual Analogue Scales) and 3-D micro topography that the oral use of marine collagen based formulations can reduce the effects of photo aging that leads to blemishes, loss of elasticity, fine lines and wrinkles.

Skin elasticity and ageing

Oral supplementation of collagen has beneficial effects. The objective of this research was to study the effectiveness of collagen hydrolysate (CH) composed of specific collagen peptides on skin biophysical parameters related to cutaneous aging. At the end of the study, skin elasticity in both CH dosage groups showed a statistically significant improvement in skin. After 4 weeks, higher skin elasticity level was determined in women.

Anti-ageing benefits of hydrolysed collagen

The effect of daily ingestion of collagen hydrolysate (CH) on skin extracellular matrix proteins was investigated. These results suggest that CH may reduce ageing-related changes of the extracellular matrix by stimulating anabolic processes in skin tissue.
