Collagen is present in all the body’s tissues, and its concentration is highest in the skin where it provides support and firmness.
However, with advancing age and ageing, the quantity of collagen present in the body and tissues gradually decreases, by about 1.5% from the age of 25 (i.e. about 1/3 less collagen at the age of 45).
This leads to a loss of hydration and a thinning of the skin, which is damaging because it becomes more fragile, drier, less elastic and prone to the appearance of the first wrinkles. The skin also loses its role as a protective barrier against external aggressions such as the sun and UV rays, the cold, the wind, etc. The skin ages even more quickly.
Marine collagen, an effective anti-ageing agent
Type 1 collagen is the most abundant form of collagen in our skin and levels are rapidly depleted due to intrinsic and extrinsic ageing processes.
Providing the body with a nutritional source of bioavailable type 1 collagen will replenish the collagen stores in the dermis and help to strengthen the skin’s natural balance.
This is where marine collagen, extracted from marine resources through a complex and innovative process, has a major role to play. Offered in the form of hydrolysed peptides that are perfectly assimilated and easily penetrate the tissues, its anti-ageing effect no longer needs to be demonstrated.
Indeed, it contributes to strengthening, repairing and supporting the spontaneous regeneration of the skin by restarting the endogenous synthesis, i.e. by our body itself. (To find out more: What is marine collagen?)
So it is easy to understand that an external and additional supply of collagen will help to strengthen our skin and prevent accelerated ageing.
It is proposed in cosmetic creams, in capsules in food supplements, sometimes combined with hyaluronic acid.
But it has also recently been proposed as a neutral-tasting powder ingredient to easily enrich everyday drinks, dishes or food preparations.
Studies carried out with a supplementation of 10 g per day of marine collagen peptides have, for example, shown :
- a significant improvement in skin hydration (+23%),
- an increase in elasticity (+24%)
- and a significant reduction in wrinkles (-9%).
In addition to a healthy diet (see Collagen-rich foods), the follow-up of these studies was 3 months, with visible results from 1.5 months.
Other studies have shown that collagen supplementation allows for the reduction of cellulite, better nail growth, healthier hair (see marine collagen for hair) and a reduction in joint pain (see marine collagen for joints)
In short, only positive effects on the health of the skin and a prolonged youth.
