Our skin is made of collagen. As we age, collagen production drops off and skin sags because it gets thinner, weaker, drier, and less resilient, or pliable. This is directly linked to amino acid content. Certain amino acids in the skin’s structure, like glycine, proline, hydroproline, and alanine – decrease with age and bad diet.

SkinPep® Collagen Re Nu® Liquid Shots contains all of the above essential amino acids, and embraces the latest scientific findings. Every day we have customers calling to tell us how Collagen Shots have improved their skin, hair and nails.

Each 10g daily serving of SkinPep® Collagen Re Nu® Liquid Shots contain Hydrolysed Marine Collagen, RE-NUTM Proprietary Complex: Calcium Ascorbate, (B3 (nicotinamide), B5 (calcium pantothenate), B6 (pyridoxine hydrochloride), B1 (thiamine hydrochloride), B2 (riboflavin), B7 (L-biotin), B9 (folic acid), B12 (cobalamin), Sodium Hyaluronate, Flax Seed powder, BlackCurrant Extract powder, sweetener: Steva 1mg per bottle.

A 2008 study in Tokyo [14] of 33 women ages 40-60 who took 10 g of Hydrolyzed Collagen daily for 2 months showed 91% saw an increase in skin hydration and resilience.

A Dermiscan study in Lyon France in 2008 showed similar findings in an age group of 35-55: an increase in skin smoothness and hydration, using the Corneometer and Skin Image Analyzer technologies. [15, 16] After 12 weeks of 10g Hydrolyzed Collagen daily, 41% less furrowing, less wrinkles, more resilient, more hydrated.

Skin resilience was measured by the C&Z Cutometer, Hydrolyzed Collagen also increases the diameter of collagen fibrils in the dermis by the same mechanism: fibroblast stimulation. This in turn increases cohesion of the dermal collagen fibers themselves, which is a true anti-aging step. In the skin, this action means increased thickness, suppleness and resilience, as well as hydration.

Hydration, or water content of skin tissue, is proven directly related to overall smoothness and decreased furrowing and wrinkling. ([9] Sumida)

What Form Collagen Is Contained In SkinPep Collagen Re-Nu® Liquid Shot?

Collagen Re-Nu® is produced from the fibrous protein extracted from the skin and scales of fish found in the sea of japan and the east china sea. e.g. rainbow trout, tilapia, paddle fish & salmon. the type of collagen of Marine collagen is called Type 1 and 3 collagen. is becoming an increasingly attractive alternative to type 2 collagen from beef or pork derived collagen. Growing concern about infectious agents such as foot and mouth disease, bovine spongiform encephalopathy and viral * infections in beef collagen has helped to accelerate the switch to marine collagen, according to "Animal Cell Technology: Basic & Applied Aspects."


How Is the Hydrolyzed Collagen Contained In SkinPep Collagen Re-Nu® Liquid Shot Produced?

Collagen Re-Nu® contains Hydrolyzed marine collagen type 1 & type 1 3, which is a pre-digested form is a form of collagen that is known to have superior absorption and numerous clinically proven benefits on the human body. It is also called collagen hydrolysate, collagen peptide. The process of hydrolysis involves breaking down the molecular bonds between individual collagen strands using combinations of heat, acids, alkalis, or enzymes.*


What Are The Clinically Proven Effects (Properties) Of Consuming SkinPep Collagen Re-Nu® Liquid Shot Every Day For More Than 21 Days.


Optimised Skin health

Marine collagen contains 17 types of the essential and non essential amino acids in a balanced ratio. It is rich in glycine, proline and hydroxyproline which are the main components in human skin.

A preclinical study investigated the effects of oral ingestion of hydrolyzed collagen, along with vitamin C , (in concentrations contained in SkinPep Collagen Re-Nu® suggested that the moisture content of skin, its viscoelastic properties, and smoothness benefit.[7]

The mechanism of action of ingested SkinPep Collagen Re-Nu® hydrolyzed marine collagen on skin may be the increased density of collagen fibrils and the fibroblasts' density (the fibroblasts being the main cells of the dermis, and those producing collagen).[8] It may be that that the peptides of ingested hydrolyzed collagen have chemotactic properties on fibroblasts[9] or an influence on growth of fibroblasts.[10]

The Glycine and proline amino acid concentration of SkinPep Collagen Re-Nu® is as much as 20 times higher than other food sources of protein. [2]. Our qualified biochemists suggest that daily supplementation of the ratio of key collagen forming amino acid, that are found in SkinPep Collagen Re-Nu® will cause the body to better respond to cell communicating ingredients like those found in high end Cosmeceuticals e.g. the SkinPep® anti ageing range and aesthetic skincare treatments e.g., micro needle rollers, radio frequency and other electronic skin and collagen stimulating therapies.


Optimised Muscle Function

SkinPep Collagen Re-Nu® Liquid Shot contains 8 out of 9 essential amino-acids,[3] including glycine and arginine[4]—two amino-acid precursors necessary for the biosynthesis of Creatine. Daily consumption of Collagen ReNu® liquid shot can result in an improvement in muscle strength and explosive energy.


Superior Digestibility

The bioavailability of hydrolyzed collagen was demonstrated in a 1999 study; mice orally administered 14 hydrolyzed collagen digested and absorbed more than 90% within 6 hours, with measurable accumulation in cartilage and skin.[5] A 2005 study found hydrolyzed collagen absorbed as small peptides in the blood.[6]

The hydrolysis process results in reducing the large collagen proteins into smaller peptides which are easily absorbed. Low molecular weight Type I fish collagen peptide is the best collagen for skin rejuvenation. There are more than 20 types of collagen in the body, but Type I collagen comprises about 90% of the collagen found in the body overall. Raising Type I collagen levels in your body by taking SkinPep Collagen Re-Nu® Liquid Shot provides noticeable anti-aging benefits.

Typically derived from salmon and red snapper, SkinPep Collagen Re-Nu® Liquid Shot (fish collagen) is up to 1.5 times more absorbent than bovine or porcine collagen because of its low molecular weight*


Joint & Bone Health

Some clinical studies report that the oral ingestion of hydrolyzed collagen decreases joint pain, those with the most severe symptoms showing the most benefit.[11][12] Beneficial action is likely due to hydrolyzed collagen accumulation in the cartilage[5] and stimulated production of collagen by the chondrocytes, the cells of cartilage.[13] Several studies have shown that a daily intake of hydrolyzed collagen increases bone mass density.[14][4] It seems that hydrolyzed collagen peptides stimulated differentiation and osteoblasts activity- the cells that build bone- over that of osteoclasts (cells that destroy bone).


Other Efficacy Assertions

It has been claimed that hydrolyzed collagen (e.g. SkinPep Collagen Re-Nu® Liquid Shot) may promote lean muscle mass through and the burning of fat rather than carbohydrates and proteins, toning and thickening skin, joint rebuilding, arterial strengthening, increased energy, organ rebuilding, alleviate osteoporosis, as well as lessening the symptoms of arthritis, high blood pressure, bladder weakness, chronic fatigue, shallow breathing, autoimmune, skin problems, and splitting nails.[25]

Porcine and bovine collagens are cheaper than fish or marine collagen, so most collagen products on the market are derived from these sources. Bovine collagen originates from cows, while porcine collagen originates from pigs. The collagen is taken from the skin or tendons of these animals. Approximately 3% of the population is allergic to bovine collagen*


SkinPep Collagen Re-Nu® Amino acid content:

The amino acid content of hydrolyzed collagen is the same as collagen. Hydrolyzed collagen contains 20 amino acids, predominantly glycine, proline and hydroxyproline, which together represent around 50% of the total amino acid content.



Amino acids Percentage
Proline/Hydroxyproline 25%
Glycine 20%
Glutamic acid 11%
Arginine 8%
Alanine 8%
Other essential amino acids 16%
Other non-essential amino acids 12%
