Human BioSciences Medifil II Collagen Particles — 100% Native Bovine Collagen, All 4 Healing Phases, 1g Vials

The only collagen particle dressing with proprietary Kollagen technology — delivering more intact native collagen to the wound surface than any standard collagen dressing. Medifil II Collagen Particles by Human BioSciences are a 100% non-hydrolyzed type I bovine native collagen wound dressing in particle form — a format that maximizes the surface area of collagen contact with the wound bed, allowing the maximum concentration of bioactive collagen molecules to interact with the wound microenvironment simultaneously. The proprietary Kollagen technology process used to manufacture Medifil II preserves significantly more of the native triple-helical protein structure of the collagen molecule than standard hydrolyzed collagen dressings — and this structural integrity is clinically critical. It is the triple-helical form of collagen that provides scaffolding for cell migration, stimulates fibroblast and keratinocyte proliferation, absorbs matrix metalloproteinases (MMPs) that degrade healing tissue, and supports all four phases of wound healing from hemostasis through remodeling. Delivered in easy-pour 1g single-use vials — apply directly to the wound bed, mix with saline for tunneling wounds, and cover with a secondary dressing.

✔ 100% Non-Hydrolyzed Native Type I Bovine Collagen — Intact Triple-Helical Structure    ✔ Proprietary Kollagen Technology — Retains More Native Protein Structure Than Standard Collagen    ✔ Particle Format — Maximum Surface Area, Maximum Collagen-to-Wound Contact    ✔ Supports All 4 Phases of Wound Healing — Hemostasis Through Remodeling    ✔ Mix With Saline for Tunneling & Cavity Wounds — Versatile Application

How Medifil II Works — Why Particle Form and Native Structure Matter

Most collagen wound dressings are manufactured from hydrolyzed collagen — a process that breaks the collagen molecule into smaller peptide fragments to make it more soluble and easier to process into sheets or gels. The problem with hydrolysis is that it destroys the triple-helical structure of the collagen molecule — the precise geometric form that gives collagen its biological activity in wound healing. Hydrolyzed collagen retains some beneficial properties but loses the structural scaffolding capability, the MMP-absorbing capacity, and the cell-signaling properties of intact native collagen. Medifil II is manufactured using Human BioSciences' proprietary Kollagen technology specifically to preserve this triple-helical structure — delivering intact, bioactive native type I collagen to the wound bed rather than collagen fragments. The particle format maximizes the exposure of this native collagen to the wound microenvironment — the small particle size creates an extremely high surface area per gram of collagen, ensuring more collagen molecules are in direct contact with wound fluid, cells, and tissue simultaneously than any equivalent-weight sheet or gel dressing can achieve.

  • Intact triple-helical structure — provides active scaffolding for fibroblast and keratinocyte migration across the wound bed
  • Absorbs matrix metalloproteinases (MMPs) — MMPs degrade healing tissue in chronic wounds, collagen acts as a sacrificial substrate to protect it
  • Stimulates healing across all four phases — hemostasis, inflammation, proliferation, and remodeling
  • Particle format — maximum surface area per gram, maximum collagen-to-wound contact
  • Reduces inflammation — collagen interaction with the wound microenvironment modulates inflammatory mediators
  • Removes exudate — particles absorb wound fluid and its harmful components
  • Retains more native protein structure than hydrolyzed collagen — Kollagen technology process protects molecular integrity
  • Compatible with topical medications — can be combined with prescribed topicals before secondary dressing application
  • Mixable with normal saline — creates injectable paste for syringe delivery into tunneling and undermined wound areas
  • 5-year shelf life — exceptional stability for stocking in clinical and home care settings

The Four Phases of Wound Healing — How Collagen Supports Each

Phase How Medifil II Native Collagen Supports This Phase
1 — Hemostasis Collagen activates platelets and supports clot formation — native triple-helical collagen is a potent platelet activator
2 — Inflammation Collagen absorbs MMPs and modulates inflammatory mediators — helps transition the wound from the inflammatory to proliferative phase
3 — Proliferation Triple-helical scaffolding supports fibroblast migration, granulation tissue formation, and angiogenesis across the wound bed
4 — Remodeling Native collagen supports organized tissue remodeling and tensile strength restoration — structural integrity of the healed wound

How to Apply — Step by Step

Step Action
1 Cleanse wound per physician order — preferably with normal saline or non-cytotoxic wound cleanser
2 Do NOT dry the wound — leave moist for best result with Medifil II particles
3 Apply topical medication to wound bed if prescribed — then apply ointment or cream to wound margin if desired
4 Pour Medifil II particles to ¼" depth across entire wound bed — for tunneling wounds mix with saline to form paste, draw into syringe, and apply to tunnel
5 Cover with appropriate absorbent secondary dressing — gauze, foam, superabsorbent, transparent film, or hydrocolloid
6 At dressing change — irrigate wound with saline until particles loosen and lift gently away

Perfect for me (update, took 1 star away) (2nd update Jul 20, 2022)
Size: 8, Color: Pastel Pack, Size: 8, Color: Pastel Pack
This product is amazing. You get 10 pairs of underwear in 5 pastel colors. Colors are exactly as shown. I used an 18 inch ruler in my pictures to show size and stretchability. The height from pant leg bottom to waist line is long so you dont worry about any buttcrack showing. It covers your thighs, too. These are nice because they added some space between the legs instead of stitching it like yoga pants where the pants legs come up and just merge together at the crotch. This underwear gives room for your lady bits and prevents cameltoes/front wedgies. The fabric on the hip area is just as stretchable as the waistband. 2021 September edit: I still love these and so I bought another pack. Simply because my other, uncomfortable underwear (not this pack) has irritated me enough. I realized that I was usually happier with my clothing when I was wearing these underwear because they are just so comfortable (and my fav colors)! They have held up very well and at least with the pastel pack, the colors still look good. The writing on the inside has held up as well. $50 for 10 super comfy pairs of underwear is great imo. Second update: I compared my new pairs to my old ones (ssme size ordered) and the waistband used to be manufactured to stretch about 2 more inches or so. The new way they created the hem is less stretchy so I took a star off my rating. My newer pairs of this underwesr will be my last choice to wear for the day compared to my first order. The blue pair in the video is part of my first order of these and pink is a pair from my newer purchase. Yes that video was a bit tricky to make lol. The pink pair was made in Pakistan and the blue was made in India. Jul 20th update: I now have significant holes in my first pairs. But this is due to both lots of wearing, and also because my cats like to knead on my clean clothes.

Mixed Feelings
Ok, so... It seems there's not much quality control for these underpants. About half of them have the back seam way too short so it doesn't come as far up in the back as it should, making it very uncomfortable if you wear them and bend forward. Be aware that there are four pretty thick seams on them. Two going right up the front and back and the two on the sides. Positives are the colors are great, and the material is very soft. I actually just wear these to bed, inside-out because of the harsh seams, and I wear them two sizes bigger than I am so they are nice and loose. I ordered my correct size to wear regularly and found that the inconsistency in the back seam was just too much for me. I will not be ordering these again.

Buyer beware
Size: 8, Color: Pastel Pack
Got these and tried on one pair cause seriously who tries on all 10 pairs when they buy underwear. They fit good a little loose but I figure they will shrink a little in the dryer. So as the label states wash before wearing I washed them all. Well then I go to put a pair on and they are way to small and I'm thinking there is no way they shrunk that much in the dryer which was on low setting. So I try on a different color one on and they fit fine. So now I'm trying more on and same thing some are good, some are small and some are big. What the heck they all say the same size inside. So this is clearly a manufacturing defect issue so I reach out to the seller. Well after going back and forth they only want to give me 30% of my purchase price back due to me having washed them and now they can't resell them. Well from where I'm sitting you shouldn't be trying to resell them anyway because they aren't even the same size. I don't usually leave bad reviews but after having read so many good ones on here and that being the reason why I bought them I figure people should be aware that they to may have the issue. So try them all on before washing.
