Marine collagen: why it becomes an essential supplement after the age of 30

Loss of firmness, wrinkles, joint pain… What if it all stemmed from an invisible yet crucial deficiency: collagen? From the age of 25, our body's production drops, accelerating skin and joint ageing. The good news is that it is possible to support collagen levels with marine collagen, scientific evidence has now shown.

Collagen is a protein essential to the structure of the skin, bones, tendons and joints. We are born with a high level of it… but it naturally declines from our thirties onwards. The reason:

  • Endogenous production that slows down with age

  • An increase in enzymes that break down collagen during ageing or periods of inflammation

  • Aggravating environmental factors: UV rays, pollution, oxidative stress, an unbalanced diet

The result: the extracellular matrix weakens, leading to sagging skin, loss of elasticity, joint pain and cartilage wear.

Collagen levels decline with age, particularly in women

A landmark clinical study (Shuster et al., 1975)(1) demonstrated a gradual decline in skin collagen with age, correlated with a thinning of the dermis. And in women, this decline is even more pronounced. Conclusion: collagen is one of the first biological markers of ageing, visible both in the skin and in joint tissues.

Why take marine collagen?

Hydrolysed marine collagen is most easily absorbed by the body thanks to its low molecular weight. Taken as a course of treatment, it acts as a signal for reconstruction, naturally stimulating collagen synthesis by the cells. 

The effectiveness of collagen peptide supplementation has been demonstrated by clinical and consumer studies for a minimum daily intake of 2.5g of collagen peptides. Excellent results have been achieved, confirming the effectiveness of marine collagen peptides in maintaining the skin’s elasticity and firmness, reducing the appearance of wrinkles and improving the skin’s beauty, radiance and evenness.

Aroma-Zone’s collagen powder scores 4.6/5… and delivers visible results

Voted ‘Best Dietary Supplement of 2024’ by the Top Santé jury, Aroma-Zone Marine Collagen is a concentrate of highly bioavailable type I peptides (2000 Da), extracted from sustainably certified farmed fish (Friend of the Sea). Manufactured in France, it is:

  • In micro-granule form for rapid, lump-free dissolution

  • Tasteless, making it easy to add to your drinks and recipes

  • Ideal for mature, dry skin that has lost its firmness

  • Suitable for athletes and anyone wishing to maintain healthy joints

Please note: it is not possible to guarantee that ingested collagen peptides will specifically migrate to skin cells. The absorbed collagen is distributed throughout all tissues via the bloodstream. This is why it is recommended to take a minimum of 2.5g per day, as in the studies (equivalent to one heaped teaspoon), in order to observe the effects of supplementation on the skin.

How can you incorporate collagen into your daily routine?

Aroma-Zone Marine Collagen is taken as a daily course of treatment, depending on your needs:

  • 1 to 2 tablespoons a day in a glass of water, a smoothie, a coffee or a tea

  • Added to your recipes: protein snacks, energy balls, homemade bars

  • In combination with other anti-ageing active ingredients (hyaluronic acid, vitamin C, etc.)

Thanks to its neutral powder form, it becomes a beauty routine as simple as your morning coffee.

You can’t see it, but when it’s lacking, everything starts to sag. Marine collagen supplementation, backed by research, is becoming an essential step in preserving youthful skin, joint comfort and overall healthy ageing. And in this category, Aroma-Zone’s version ticks all the boxes: effectiveness, traceability and naturalness.
