Mari-Coll NPNF is a hydrolised liquid marine collagen that is used in skin, hair and nail products. It is derived from deep-water fish.
Hydrolised marine collagen is water soluble and can be added to water phase or cool down phase of formulations at about 5% rate.
I ordered the marine collagen and the whole transaction was seamless, will definitely be ordering other items.
good value for money and only positive results so far
