Why it matters

Skin, hair and nails renew continuously — collagen is among their structural components.

Type I and III collagen form the bulk of skin structure — including the tissue in which hair and nails are anchored.

My skin and hair are in better shape. My hair feels stronger and has more vitality. My skin looks fresher and feels firmer. For me, it took a good six weeks.

What to expect

Collagen production takes time.Skin, hair and nails improve step by step.

When bioactive collagen peptides activate your fibroblasts, collagen production increases gradually, and visible changes emerge from within.

Hydration & fullness

Early improvements appear as your skin retains more moisture and feels noticeably plumper.

Elasticity & texture

As your fibroblasts build new collagen, your skin becomes more resilient and smoother.

Firmness & structure

Skin looks visibly firmer, hair feels stronger, and nails become more resilient.

Some customers report early changes

Easy to build into the morning, completely unobtrusive in taste. After the first few weeks I'm curious to see how it develops.

My skin has become more even – that was the first thing I noticed. My hair followed later.

    Good experience

    I have been using the collagen powder for about a year now and am very satisfied with it. I had severe hair loss and now a lot of new hair is growing back and the hair loss has reduced a great deal. My nails also grow much faster than before. I think you really do have to take the powder consistently every day for it to work.

    Assessment

    Why are there two spelling mistakes in four words here? I have only been taking the product for two weeks. So far I cannot see any change. Perhaps ask again in four weeks.

Questions about collagen for skin, hair and nails

How collagen peptides support skin, hair and nails, how to take the powder, and when changes may become noticeable.

Why collagen for skin, hair and nails?

Skin is made up largely of collagen — above all type I. Together with elastin, these fibres form a network that gives skin its structure and firmness.

Hair and nails, by contrast, are not made of collagen but of keratin. That is a different protein with a different structure. The connection runs through the building blocks: collagen peptides supply amino acids such as proline and glycine, which the body also uses to form keratin.

The skin's natural collagen content declines with age. That is a normal process.

What are fibroblasts, and why are they important?

Fibroblasts are specialised cells in the skin. They produce collagen, elastin and other components of connective tissue, and in doing so maintain the structure of the dermis.

For that work they need amino acids as raw material — particularly glycine, proline and hydroxyproline, which make up the largest share of the collagen molecule. Those are precisely the amino acids collagen peptides supply in concentrated form.

Fibroblast activity slows with age. That is one of the reasons skin becomes thinner and drier.

How do I take the collagen?

Our collagen fits easily and flexibly into your daily routine.

Powder:
Stir the recommended daily amount into water, coffee, tea, or a smoothie. It is tasteless and dissolves well in both cold and warm drinks.

Capsules:
Take the recommended daily dose with plenty of liquid - ideally with a meal.

When will I see results?

The studies on collagen peptides work with periods from eight weeks up to several months of daily intake. Shorter periods are barely studied. How it plays out for you personally depends on age, diet and how regularly you take it.

Why exactly 90 days?

Collagen is continuously built up and broken down in the body. The studies on collagen peptides therefore work with periods of several months — 90 days matches that order of magnitude.

Why bioactive peptides — and not just collagen?

These are bioactive collagen peptides — a specific peptide fraction studied clinically for targeted effects. Generic collagen has an undefined peptide structure and is usually not clinically studied.

Is long-term use safe?

Yes. The peptides used have been studied in long-term trials over several years.

Taken daily. Benefits build over time.
