Efficacy of Vinh Wellness Collagen on Skin Health

A Randomized, Triple-blind, Placebo-controlled, Parallel Study to Evaluate the Efficacy of Vinh Wellness Collagen on Skin Elasticity, Wrinkles, and Moisturizing Effect

The most visible signs of aging are on the skin. As skin gets older it shows a decrease in epidermal thickness, with a flattening of the dermal-epidermal junction. At the same time, loss of elasticity and wrinkle formation begin. The objective of this randomized, triple-blind, placebo-controlled study is to evaluate the efficacy of Vinh Wellness Collagen on skin elasticity, wrinkles, and hydration over 12 weeks.

Study Overview

• Status: Completed
• Conditions: Skin Manifestations; Skin Abnormalities
• Intervention / Treatment: Dietary supplement: Placebo; Dietary supplement: Vinh Wellness Collagen

Detailed Description

Skin appearance is known to be influenced by endogenous and environmental factors, including nutrition, hormones, as well as exposure to chemicals, smoking, or ultraviolet radiation. The ability of nutritional supplements to enhance skin characteristics has received increasing attention as the population continues aging. A recent study assessed the correlation between nutrient consumption and skin-aging appearance, including skin wrinkles, dryness, and atrophy, and determined that higher intake of linoleic acid and vitamin C, as well as lower intake of fats and carbohydrates are linked with improved skin appearance. Moreover, clinical trials examining the effects of nutritional supplementation with proteins, vitamins, fatty acids, and trace minerals, have suggested that dietary compounds can modulate skin health and function.

As skin gets older it shows a decrease in epidermal thickness, with a flattening of the dermal-epidermal junction. The dermis is the skin layer directly below the epidermis and has decreases in thickness by about 1% per year throughout the adult lifespan. Structural components of the dermis include collagen, elastic fibers, and extrafibrillar matrix. The cosmetic industry has focused its research on supporting these connective tissue components, as they have been established to repair skin damage (i.e. wounds) and enhance the strength and radiance of the skin.

Collagen is the most abundant protein in mammals and is currently being utilized by a diverse number of industries including nutrition, cosmetic, and biomedical fields. Gelatin, which is used extensively in the food sector, is a hydrolyzed analog of collagen and is an excellent source of protein. A subsequent enzymatic degradation of gelatin results in the generation of collagen hydrolysate (CH), which contains peptides of an average molecular weight of 3-6 kDa. Human bioavailability studies have demonstrated that hydrolyzed collagen peptides are present in the blood within 2 h following oral ingestion of gelatin derived from chicken or fish and are present up to 24 h later.

A double-blind, placebo-controlled trial on 69 women treated with a daily CH treatment or placebo for 8 weeks reported that skin elasticity was significantly improved. Skin moisture and skin evaporation were also enhanced but did not reach statistical significance relative to the placebo group. In addition, other studies have examined the effect of daily ingestion of CH (10 g) or placebo on skin hydration in healthy Japanese women over 2 months and found that there was a gradual improvement in skin water absorption capacity. The objective of this randomized, triple-blind, placebo-controlled study is to evaluate the efficacy of Vinh Wellness Collagen, a CH derived from pangasius skin, on skin elasticity, wrinkles, and hydration over 12 weeks of use.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cheek skin elasticity	Cheek skin elasticity will be measured using the Cutometer® (MPA 580), which applies the suction method of negative pressure. The skin is drawn into the aperture of the probe using negative pressure, and after a defined time, is released again. The resistance of the skin to the negative pressure (firmness) and its ability to return into its original position (elasticity) are displayed as curves (penetration depth in mm/time) in real time during the analysis.The difference in cheek skin elasticity, measured as Gross skin elasticity (R2), between Vinh Wellness Collagen and placebo supplemented participants after 12 weeks. Cheek skin elasticity will be on a scale of 0-100; 0= no improvement, 100 = great improvement.	12 weeks from baseline

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Underarm skin elasticity	Underarm elasticity will be measured using the Cutometer® (MPA 580), which applies the suction method of negative pressure. The skin is drawn into the aperture of the probe using negative pressure, and after a defined time, is released again. The resistance of the skin to the negative pressure (firmness) and its ability to return into its original position (elasticity) are displayed as curves (penetration depth in mm/time) in real time during the analysis. The difference in underarm skin elasticity between Vinh Wellness Collagen and placebo supplemented participants after 12 weeks. Underarm skin elasticity will be on a scale of 0-100; 0= no improvement, 100 = great improvement.	12 weeks from baseline
Cheek Skin hydration	Cheek skin hydration is evaluated by the Corneometer® (CM 825) using the capacitance method, which is based on the different dielectric constant of water and other substances. Using the corneometer probe, an electric scatter field penetrates ting during the measurement and the dielectricity is determined. The results are stored on the device software as arbitrary units. The difference in cheek skin hydration between Vinh Wellness Collagen and placebo supplemented participants after 12 weeks. Cheek skin hydration will be on a scale of 0-100; 0= no improvement, 100 = great improvement.	12 weeks from baseline
Nasolabial wrinkles	Nasolabial skin wrinkles will be measured by the Modified Fitzpatrick Wrinkle Scale using images acquired by VISIA imaging which utilizes multi-spectral imaging and analysis capture visual information for wrinkles. The difference in nasolabial wrinkles between placebo and Vinh Wellness Collagen participants after 12 weeks of supplementation. The Modified Fitzpatrick Wrinkle Scale (MFWS) is a validated questionnaire that can evaluate skin wrinkle severity. It is on a scale of 0-3; 0 = no wrinkle, 3 = deep wrinkle.	12 weeks from baseliine
Skin quality using visual analogue scale (VAS) scores	Skin quality takes account of different measures including skin elasticity, skin hydration, radiance of skin, skin firmness, skin wrinkles and overall feel of skin. Each of these parameters are measured on a scale of 0 - 100; 0 = no improvement. 100 - great improvement. The difference in skin quality VAS scores between placebo and Vinh Wellness Collagen supplemented participants after 12 weeks of supplementation ona scale of 0 - 100; 0 = no improvement, 100 - great improvement.	12 weeks from baseliine
Net Skin elasticity	The difference in cheek skin elasticity measured as Net Skin elasticity (R5), between Vinh Wellness Collagen and placebo supplemented participants after 12 weeks. Net skin elasticity is the elastic (immediate stretch) component of the skin without the viscous deformation. Data is represented as the difference between baseline and week 6, baseline and week 12 and between week 6 and week 12. A negative value indicates loss of skin elasticity while a positive number denotes an improved elasticity	Baseline, week 6 and week 12.
