Why we use different sources of collagen in powders vs skincare

What’s the best collagen type for skincare + powder supplements?
When it comes to collagen, one size (or source) doesn’t fit all. That’s why we use different collagen in our powders + skincare ~ each carefully chosen to give your body + skin exactly what they need, in the form they’ll benefit from most.
At Adashiko, we’re all about results you can see + feel ~ which is why we don’t follow trends when it comes to collagen sourcing. We look at the science, consider what your body needs at different levels + choose the form that delivers the best performance.
Let’s break down how the collagen in our powders differs from our skincare + why that’s a very good thing.

Porcine collagen for inner support
Our collagen powders are made from premium hydrolysed porcine collagen peptides, rich in Type I + III collagen (and Type II in our Joint formula). Why porcine? Because its amino acid profile most closely matches our own, making it easier for your body to absorb + put to good use.
Porcine collagen supports everything from skin elasticity, hydration + gut health to muscle tone, organ support + joint function.
You can read more about why we believe porcine outperforms marine + bovine collagen in this blog post ~ but here’s the short version: better absorption, broader benefits + fewer reactions.
Marine collagen for surface-level hydration
In contrast, our skincare collection is formulated using pure, peptide marine collagen ~ a water-retaining powerhouse when applied topically.

Marine collagen molecules, when hydrolysed into smaller peptides, are better able to penetrate the skin’s outer layer. Once absorbed, they work to:
- Attract + retain moisture
- Plump + smooth the skin’s surface
- Soften the appearance of fine lines + wrinkles
- Support a dewy, firm + hydrated glow
Our skincare is consciously crafted to give your skin an extra collagen boost from the outside in, complementing the deeper internal support offered by our powders.
Why we don’t use porcine collagen in skincare
While porcine collagen is the gold standard for internal use, it’s not the best fit for topical application. Marine collagen has a smaller molecular structure that allows it to bind better with water + absorb into the outer layers of the skin.
That’s why marine collagen is the hero of our skincare ~ it offers fast, visible improvements in hydration + skin texture, especially when combined with other active, skin-loving ingredients.
Collagen inside + out = real results
Think of your skincare + collagen powders as a team. One works deep within, the other focuses on your skin’s surface. And together, they create beautiful results.
Powders for inner support:
Skin structure, elasticity, hydration, gut + joint health
Skincare for visible glow:
Moisture retention, plumpness + texture
Both our collagen + skincare formulas are pure, potent + free from fillers, or unnecessary extras. Just targeted support, exactly where you need it.
