How Collagen Promotes Healthy Skin

Skin is one of the largest organs of the human body, compromising almost 15% of ones weight. Healthy skin can be achieved from within more so than using topical creams. The skin is made up from three layers. The epidermis, dermis and the subcutaneous layers.


The epidermis is the outermost layer of the skin. It is made up of three cells which are keratinocytes, melanocytes, and langerhans cells. Keratinocytes make up the majority of the epidermis, forming at the bottom of the epidermis. It moves up to the top of the layer, forming a protective barrier. Melanocytes are responsible for producing melanin, giving the skin it’s color and tone. Langerhans are the immune system of the skin, protecting it from foreign substances that can penetrate the skin.


The dermis is the middle layer of the skin. It is the thickest of the three layers, composed of a mesh of collagen and elastin. Collagen is the support structure of the skin, while elastin is the flexible properties of the skin. Fibroblasts are the main cells found in the dermis. Fibroblasts synthesize the collagen and elastin. Capillaries are present in the dermis for oxygen and nutrients. Wrinkles start to form in the dermis.


The subcutaneous layer is the deepest layer of the skin. It’s mainly made up of fat, acting as an insulator and shock absorber.

Collagen Supplements For Healthy Skin

Maintaining the amount of collagen is the key to healthy skin. Glycine and proline are the main constituents of collagen; replenishing these constituent amino acids appears to be needed to maintain the amount of collagen at healthy levels.

Studies have shown that glycine production in the body and what we consume from our normal diets may not be adequate for collagen synthesis.[1] Vital Proteins Collagen Peptides contains 4 grams of glycine. Glycine may also the support the production of creatine in the body, which can help stimulate cells to produce collagen.

Proline can help break down protein and form healthy cells for the collagen and elastin structures.

When trying to achieve healthy skin, it is important to focus on how to build it from the inside of the body just as much as the outside. Balancing amino acids within your diet can have great effects on how collagen is synthesized from within.
