What You Need to Know

Type 1 collagen is found in skin, hair, nails, muscles, joints and organs and starts declining after we turn 25. Unflavoured with no added ingredients, it’s easy to digest. Made with MSC-certified wild Norweigan cod skin. Pure, simple, easy.

Tips for taking

We take 5-10g a day (or 5000mg-10,000mg), which is roughly 2-4 teaspoons (rounded if using a cutlery teaspoon, and level if you're using a measuring teaspoon). Serving size varies. We're all different – so are our supplementation needs.

Add our pure marine collagen to your coffee or a smoothie. Our founder puts hers in her protein shake, and you can’t taste it at all. You can also bake with it. We have recipes on our blog. Scroll down to the FAQs for more information about Skinful Pure. For general collagen, see our collagen collection page.

Why Skinful is different

  • Quickly and easily absorbed

    Our pure marine hydrolysed collagen peptides are tiny (for the pros: less than 3,000 Daltons in weight) and easier for your body to absorb, which means you’ll feel the benefits faster. 

  • Trusted by clinicians & families

    Over half of our sales come from nutritional therapists, doctors, and experts who are very selective and sceptical about collagen. They see the real-life results and continue to recommend us.

  • Our Norwegian supplier is the best

    We personally know and trust the people who make our collagen. It was the first to be MSC certified, it’s independently tested for purity and they don’t use harsh chemicals to bleach the cod skin.

  • Simple and great value for money

    It’s not difficult to sling a spoonful in your coffee or protein shake. It also means no added ingredients and a much better cost per dose. 8 times cheaper than the best-selling gag-inducing, sugary premixed liquid sachets, in fact.

    Very pleased

    I’ve been using Bare Biology Marine collagen for about four years now and I have definitely seen an improvement on my skin on my hands (and therefore assume it’s improved my skin elsewhere too!) . I have thick hair anyway, but my hair seems to be in good condition.

    Fabulous

    A superfine powder that mixes easily in a drink. Tastes a bit fishy but that's to be expected with marine collagen. What I really like is that it's not mixed with 'fillers'. Still at the beginning of my collagen journey but so far my skin feels smooth and fine wrinkles look less obvious. A great company with fantastic customer service too.

    Best collagen to add in your coffee

    I’ve been taking this for at least a year. My hair and my skin benefit from it as they look great.

    No taste, I just pop one spoon in my coffee first thing in the morning
