Collagen 101

There are currently 27 known types of collagen in the body. However estheticians only need to concern themselves with Collagens I, III, IV and VII – that make up the papillary and reticular dermis the Extracellular Matrix (ECM). Collagens responsible for keeping skin flexible and firm. One educator I studied under suggested we should think of them as coiled springs on a mattress.

Types of Collagens:

Collagen I – found in the Papillary Dermis

Collagen III – found in the Papillary Dermis

Collagen IV – in the Epidermal-Dermal Junction

Collagen VII – in the Epidermal-Dermal Junction

Elastin – fibers found in abundance in the Reticular Dermis; gives skin its tensile strength and definition.

There are several factors involved in collagen synthesis. Take a look at this video for a quick lesson. NOTE: This video is intended for professional skin therapists so it might be boring to you laymen and women.

    HOW did you learn all of your amazing information about Collagen? Do you recommend oral supplements? Drinks?

    How do you feel about Hyaluronic Acid?
    Large molecule? Small Molecule? Combination?
    Expensive brands vs drug store or generic brands?

      Hi Liptastick. It’s just information I’ve accumulated over time. Since ingesting collagen increases HA, I’m definitely in favor of taking oral supplements.

      Perhaps I should write a blog post on Dalton weights of various HA molecules. Thanks for the idea.
