After the age of 25, natural collagen production decreases by around 1% per year. Gradually, the skin loses firmness, the first fine lines appear, and the complexion becomes dull. In response, collagen supplements have exploded in popularity - but not all forms are created equal. Here is what you really need to know before choosing one.
Understanding collagen's role in the skin
Collagen is the most abundant protein in the human body. In the skin, it forms the framework of the dermis: it is what provides firmness and structure. It works alongside elastin (which provides elasticity) and hyaluronic acid (which retains water and hydrates). Together, these three components form the structural scaffolding of your skin.
From the age of 25, collagen production slows down. By the age of 50, it may have decreased by half. UV rays, smoking, oxidative stress, and sugar further accelerate this degradation. The visible result: less toned skin, deeper wrinkles, and reduced hydration.
The different forms of collagen: what really sets them apart
The market offers several sources of collagen. Marine collagen (extracted from fish or shellfish) is the most widespread: it has an interesting amino acid profile, but its protein quality score (PDCAAS) is limited (0.3 to 0.5), and its taste can be unpleasant. Bovine collagen offers an alternative, but raises traceability concerns. Plant-based collagen is not technically collagen: it generally consists of ingredients that stimulate its production (vitamin C, zinc), without directly providing any.
A lesser-known but very promising option is eggshell membrane. It naturally contains type I, V, and X collagen, elastin, and hyaluronic acid - the three key components of skin structure, brought together in a single complete matrix. Its amino acid profile is particularly close to that of skin, which promotes optimal absorption. Its PDCAAS score (0.73 to 0.75) is significantly higher than that of conventional collagens.
Choosing the right collagen supplement
Several criteria determine a supplement's actual effectiveness. First, bioavailability: collagen that is poorly absorbed by the body will not produce visible results. Next, dosage: clinical studies show effects at specific doses - beware of underdosed products that rely on marketing appeal. The presence of cofactors is also essential: vitamin C is indispensable for collagen synthesis, zinc supports cell regeneration, and antioxidants (selenium, vitamin E) protect existing fibers from oxidative stress.
Finally, choose a formula whose effectiveness is supported by controlled clinical studies, rather than solely by testimonials or vague claims.
Epycure's solution for denser, plumper-looking skin
Our Plumper Skin Treatment is formulated with Reggenerate™, a patented eggshell membrane extract naturally concentrated in collagen (types I, V, and X), elastin, and hyaluronic acid. Unlike isolated hydrolyzed collagen, this complete matrix works synergistically for a much more effective anti-aging action: a study published in 2026 showed that 300 mg of Reggenerate™ was more effective than 8 g of conventional hydrolyzed collagen.
The active ingredient is supported by several randomized, double-blind clinical studies at a dose of 300 mg/day (the dose in our formula): +51% firmness, +25% elasticity, and -33% skin fatigue in 60 days. The formula also contains borage oil for deep hydration, vitamin C, which contributes to normal collagen formation to support normal skin function, zinc and biotin, which contribute to maintaining normal skin, and the vitamin E + selenium duo, which helps protect cells against oxidative stress.
The formula contains 95.1% ingredients of natural origin, is made in France, and is B Corp certified. It is suitable for all profiles from the age of 12, regardless of the age at which you start the treatment. The Lab'Epycure confirms: 97% find the treatment effective for skin appearance and firmness, 97% have more hydrated skin, and 78% notice less visible wrinkles (32 people, 3 months).
Progressive effects: Day 30, optimized hydration; Day 60, refined skin texture; Day 90, visibly improved firmness. For an even more complete action, our Beautiful Skin Duo combines the Plumper Skin Treatment with Blemish Gummies for a synergistic beauty-from-within routine.
