Peptides have become a buzzword in skincare. They are short chains of amino acids, designed in labs to signal the skin to produce more collagen or elastin. They can work, but they are man-made, often fragile in formulas, and usually come with a high price tag.
Marine bio-actives offer another way. Instead of relying on synthetic fragments, extracts from seaweed and marine microorganisms naturally stimulate the skin’s own renewal pathways.
1. Where They Come From
- Peptides: Lab-designed molecules, produced synthetically.
- Marine Extracts: Certified organic fucoidans and marine post-biotics like Alteromonas ferment extract, cultivated sustainably through biotechnology.
2. What They Do for the Skin
- Peptides: Signal skin cells to make more collagen or elastin. Effects depend on stability in the formula.
- Marine Extracts:
- Fucoidans encourage collagen, elastin, and hyaluronic acid production naturally.
- Alteromonas ferment extract boosts the skin’s own HA production (+29%), collagen (+20%), and elastin (+23%).
- Both work in harmony with the skin microbiome, with clinical studies showing firmer, denser, plumper skin.
3. Environmental Impact
- Peptides: Synthetic, made in labs through chemical or recombinant processes.
- Marine Extracts: Renewable, biodegradable, produced with blue biotechnology powered by renewable energy.
Why I Chose Marine Extracts Over Peptides
Synthetic peptides can be clever, but the ocean already provides natural solutions that are effective, clinically proven, and far more sustainable. That’s why you’ll find marine actives at the heart of my Oceanic creams.
At-a-Glance: Peptides vs Marine Extracts Summary
| Aspect | Peptides | Marine Extracts |
|---|---|---|
| Source | Synthetic, lab-made molecules | Certified organic seaweed & marine biotechnology |
| Skin Benefits | Signal collagen and elastin production | Boost collagen, elastin, HA naturally; clinically proven anti-ageing |
| Sustainability | Synthetic lab production | Renewable, biodegradable, grown with blue biotechnology |
