Your route to a natural glow
A natural glow: out of reach?
Do you want a naturally radiant complexion that looks fresh and rested? You may have tried countless creams, serums and tinctures hoping to find that glow again. It often feels like a fight against time: with every passing year skin seems to lose firmness and fine lines become more visible. But what actually happens in the deeper layers of your skin?
The science behind the trio
Skincare is full of ingredients that promise a great deal. Here we take a closer look at three of them: collagen, hyaluronic acid and vitamin C. Each of the three has its own job in your skin.
Collagen: the foundation for firmness
Collagen is the most important structural protein in the body and forms the framework that gives your skin firmness, resilience and elasticity. With age, natural collagen production declines, which can lead to wrinkles and a slacker appearance. In one study, women aged 45 to 65 took 2.5 g of collagen peptides or a dummy product (placebo) daily for eight weeks. Afterwards, eye wrinkle volume in the collagen group was 20% lower than with placebo. Skin samples also contained more procollagen I (65%) and elastin (18%).¹ Procollagen I is the precursor of collagen and shows how much new collagen the skin is making; elastin is the protein that lets skin stretch. One specific product was tested, and skin samples were taken from only some of the women.
Hyaluronic acid: the key to hydration
While collagen provides structure, hyaluronic acid is the key to hydration. Think of it as a tiny but remarkably powerful sponge, binding moisture in the deeper layers of your skin. That ability is what keeps skin looking plump and smooth. In studies where hyaluronic acid was taken by mouth, skin moisture rose over several weeks and dry skin was rated as less dry.² Skin moisture describes how much water the outer layer of skin holds; dry skin holds too little. These studies looked at hyaluronic acid, not collagen.
Vitamin C: the engine of synthesis
The real work happens when those two meet their indispensable partner: vitamin C. Vitamin C contributes to the protection of cells from oxidative stress and to normal collagen formation for the normal function of skin, bones and cartilage. Without enough vitamin C your body cannot stabilise and use the collagen it produces. An analysis looked at the diets of 4025 women (American Journal of Clinical Nutrition). Those with a higher vitamin C intake were less likely to have wrinkled-looking skin or age-related dry skin.³ This is an observation of what people ate, not a trial: it shows a link, but not that vitamin C was the cause. It is the engine that keeps the whole system running and makes sure the building blocks are processed correctly.
The builder: collagen, the foundation of your skin
What is collagen, exactly?
Collagen: more than a beauty protein
At up to 30%, collagen is the most abundant protein in your body. You will find it almost everywhere — not only in your skin, but in your bones, cartilage, tendons, ligaments and even the walls of your blood vessels. The name collagen comes from the Greek word for glue: as a scaffold protein, it gives tissues their shape and makes them hard to tear.
The scaffolding function of your skin: a dense, flexible network
Picture your skin as a fine-meshed, resilient network. Collagen forms exactly that scaffold in the dermis, the middle layer of the skin. It is this dense mesh that keeps your skin taut, plump and elastic. It supports the skin cells, allows them to function properly, and makes sure the skin returns to its original shape after every movement. A healthy collagen structure is the reason young skin looks so smooth and feels so firm. In one study, 105 women with cellulite took either 2.5 g of collagen peptides or a dummy product (placebo) daily for six months. Afterwards the density of the deeper skin layer (dermis) was higher than with placebo. Cellulite decreased mainly in women of normal weight, less clearly in overweight women.⁴ This density describes how tightly packed the connective tissue beneath the skin surface is. One specific product was tested in women with cellulite.
The biological builder: how your body makes collagen
The process of collagen synthesis is complex and fascinating. It begins with your body taking in particular amino acids — the basic building blocks of proteins — such as glycine, proline and hydroxyproline. In the fibroblasts, specialised skin cells, these amino acids are linked into long chains that then wind into a unique triple helix structure. It is this stable form that makes collagen so resilient and provides the basis for its scaffolding function.
So what is in our products? Our products supply high-quality collagen hydrolysate with the amino acids glycine, proline and hydroxyproline. Hyaluronic acid is in the vegetarian collagen complex; the ingredient list shows exactly what each product contains.
Why your collagen production declines with age
The natural breakdown process
From around your mid-twenties, your body's own collagen production begins to decline slowly but steadily. The decline continues over the years. This is a natural process, and it means your skin becomes thinner over time, loses elasticity, and the first fine lines and wrinkles appear.
External factors that speed up collagen breakdown
Alongside the natural ageing process there are a number of factors that can accelerate the breakdown of collagen in your skin. They include:
- UV radiation: excessive sun exposure is the greatest enemy of your collagen fibres. UV rays damage the collagen and elastin in the skin; this damage is thought to be why skin that gets a lot of sun looks wrinkled.⁵
- Stress: chronic stress leads to the release of cortisol, a hormone that promotes collagen breakdown.
- Sugar: a diet high in sugar can lead to a process called glycation, in which sugar molecules bind to collagen fibres and harden them. This makes the fibres stiff and brittle.
The catalyst: vitamin C, the essential helper
The essential role of vitamin C in collagen synthesis
An indispensable cofactor
Collagen cannot simply appear from nowhere. It needs a decisive helper to start the process and keep it running: vitamin C. This vitamin is a vital cofactor for the enzymes (hydroxylases) responsible for hydroxylating the amino acids proline and lysine. That chemical modification is essential to building collagen's stable triple helix. Without it the collagen molecule would be unstable and could not perform its scaffolding function in your skin. A review summarises the role of vitamin C as a cofactor in this hydroxylation and reports the cell-culture data recorded on it.⁶
The glue analogy: no stable scaffold without vitamin C
Imagine trying to build a house where the cement is crumbly and does not hold the bricks together. That is collagen without vitamin C. The vitamin acts as the glue that binds collagen fibres firmly together and gives them their tensile strength. Only when your body has enough vitamin C can newly formed collagen be assembled into a stable scaffold.
More than a building block: vitamin C protects and renews
Vitamin C as an antioxidant
Vitamin C is also a strong antioxidant. It neutralises free radicals — unstable molecules produced by environmental factors such as UV radiation and pollution. Free radicals can damage your cells and accelerate the breakdown of collagen. Vitamin C contributes to the protection of cells from oxidative stress. A dermatology review reports that, in the lab, vitamin C applied to the skin reduced redness from UVB rays and the number of skin cells damaged by sunburn.⁷ This concerns vitamin C applied to the skin; it says nothing about vitamin C taken by mouth.
For an even, radiant complexion
Would you like a more even skin tone? Vitamin C comes up in research on this too. A review reports that in experiments with compounds derived from vitamin C, less melanin was formed, both in pigment cells in the lab and in living organisms. Melanin is the pigment that colours skin and dark spots brown. In addition, certain enzymes involved in making collagen need vitamin C in order to work.⁶ Dermatologists mostly apply vitamin C to the skin, because too little of it reaches the skin when it is taken by mouth.⁷

The moisture reservoir: hyaluronic acid for plump skin
The remarkable ability of hyaluronic acid
The hydration molecule
Hyaluronic acid (HA), often celebrated as the star of moisturising care, is a glycosaminoglycan with a remarkable molecular ability to bind water. Its distinctive, sugar-like structure lets it hold large quantities of water in a gel-like state. In fact, hyaluronic acid can hold many times its own weight in water. That makes it an essential moisture reservoir, keeping skin plump and hydrated from within. A review describes hyaluronic acid as the key molecule for skin moisture because of its unique capacity to retain water.⁸
The sponge analogy: an invisible filler
Think of your skin as a sponge that needs moisture to look full and plump. Hyaluronic acid is that sponge. It occupies the spaces between the collagen and elastin fibres in the dermis and fills them with moisture. That gives your skin both its fullness and its natural resilience. This cushioning shapes how smooth the skin surface looks.
The visible effects on your skin
Plump and smooth: fewer fine lines
How much water is held in the deeper layer of the skin shows on the surface. Well-filled water stores in the deeper skin layer make fine lines look less deep. A review reports on a study of 61 people with dry skin who took 120 mg of hyaluronic acid or a placebo daily for six weeks. The clearest drop in dryness and rise in moisture were seen in those taking hyaluronic acid.⁹ The participants had dry skin; whether normal skin responds the same way, the study does not show.
Better elasticity and resilience
Well-hydrated skin is not only plumper but more elastic. The moisture hyaluronic acid binds makes skin suppler and more resilient to mechanical stress and environmental exposure. That reduces the risk of dryness lines and helps skin recover from daily demands. In the deeper layer of the skin (dermis), collagen fibres and hyaluronic acid sit together in the tissue between the cells.
Strengthening the skin barrier
The skin barrier is also linked to how much water the skin holds. A well-hydrated barrier is intact and better at preventing moisture loss and the entry of pollutants and irritants. So water content and barrier are closely linked.
The unbeatable team: synergy in action
How the trio plays together
Who does what: scaffold, catalyst, water reservoir
The three substances have different roles in the skin. Picture them as a well-drilled team: collagen is the builder, forming the stable scaffold and foundation of your skin. Vitamin C is the indispensable catalyst and engineer, making sure the building blocks are assembled correctly and stably. And hyaluronic acid is the masterful hydrologist, filling the whole scaffold with vital moisture. So each of the three has its own job.
The perfect interplay: a molecular dance
The way this trio works together is a fascinating performance at the molecular level. First your body supplies the necessary collagen peptides. Then vitamin C comes in: certain enzymes need it to chemically modify two building blocks of the collagen chains (proline and lysine), which makes the collagen molecule stable.⁶ Without that stabilisation the collagen would be unusable and the skin would lose its firmness. Once the collagen scaffold is standing, hyaluronic acid takes over. It settles into the spaces of the new collagen network and binds water. This supplies the firm scaffold with moisture, which makes the skin plump and elastic. That is how structure and moisture interlock in the skin.
Why the combination is the best solution
The whole-picture effect: from the base to the surface
The three substances sit at different levels of the skin. Many skincare products work only on the surface, by adding moisture. That affects the top layer of the skin, not the collagen in the dermis. The three are usually described by their role in the tissue: collagen peptides as amino-acid raw material, vitamin C as a cofactor in collagen chemistry, and hyaluronic acid as a water-binding molecule of the dermis. A small pilot study without a comparison group followed 26 women who took a cartilage extract containing type II collagen and hyaluronic acid for twelve weeks. By the end their skin was less dry and flaky.¹⁰ Without a comparison group, the study cannot tell whether the changes came from the extract or would have happened anyway.
Maximum results: more than the sum of their parts
Some studies have examined these three substances taken together rather than separately. Whether combined intake differs from single intake is not settled. Hyaluronic acid binds water, and the collagen scaffold gives it the space to do so. Collagen fibres and hyaluronic acid are both components of the dermal matrix in which the fibroblasts sit. A study compared a drink with a dummy product (placebo) in 72 women over twelve weeks. The drink contained 2.5 g of collagen peptides, vitamin C, zinc, biotin and vitamin E. Skin moisture, elasticity, roughness and density came out more favourably in the drink group than with placebo.¹¹ Elasticity describes how well skin springs back after being stretched. Because a mixture was tested, the result cannot be traced to a single ingredient, and it contained no hyaluronic acid.
Collagen, hyaluronic acid and vitamin C at a glance
The three substances occupy different roles in the skin: collagen forms the fibre scaffold, hyaluronic acid binds water in the dermis, and vitamin C is a cofactor in collagen chemistry.
Your route to radiant skin: practical tips
Taking it correctly for the best results
You now have a deep understanding of how the magic trio works together. But how do you put that knowledge into practice day to day? Here are some practical tips for taking your skincare to the next level.
Finding the right dose
Studies of collagen peptides mostly used daily amounts between 2.5 and 15 grams. The Kollagen Institut daily serving is 2.5–5 g. If you are new to collagen supplementation, start with a lower dose and increase it slowly. What matters is that you stay consistent. The motto: regularity beats quantity. If you take collagen, take it every day. For vitamin C and hyaluronic acid, follow the dosing recommendations on the product itself, as these can vary with concentration.
Quality over quantity
When choosing your products, pay close attention to quality. With collagen, bioavailability is decisive. Look for products containing collagen hydrolysate, since this is broken down into smaller peptides your body absorbs easily. Ideally your collagen should be neutral in taste and smell, so you can mix it into your favourite drink or your meal without trouble. For vitamin C, capsules or powder are a good choice, while hyaluronic acid is often sold in capsules or as a liquid.
The perfect time to take it
When is the best time to take the trio? Many experts recommend taking collagen and hyaluronic acid in the morning or the evening. In the morning it fits well with breakfast for many people, in the evening with your last meal or a warm drink. You can take vitamin C at any time of day. Find a routine that fits best into your day and that you can keep to consistently.

Nutrition that strengthens from within
Your diet also supplies building blocks your body needs to make collagen.
Collagen building blocks in your kitchen
Supplements are not the only source of collagen building blocks. There are many foods that supply the necessary amino acids and nutrients. Bone broth is one of the richest natural sources of collagen. Oily fish, lean meat and eggs also contain the important amino acids proline, glycine and lysine. Include these foods regularly in your eating plan.
Vitamin C powerhouses for synthesis
Since vitamin C is the decisive helper for collagen synthesis, you should make sure your diet is rich in it. Peppers, broccoli, Brussels sprouts, kiwis and citrus fruit are real vitamin C powerhouses. Acerola cherry is one of the best sources, as it contains an extremely high concentration of this vitamin. A daily smoothie with these ingredients is a simple and tasty way to cover your needs.
Why hydration is unbeatable
Hyaluronic acid can only bind water if there is enough of it. Drinking enough water is the simplest and most important step for hydrating your skin from within. It not only flushes out toxins but also makes sure your skin cells are optimally supplied with moisture. Try to drink at least 2 to 3 litres of plain water spread across the day.
In closing: back the power trio
You have seen what happens in the deeper layers of your skin. You now know that collagen is the structural foundation of your skin, that vitamin C is the indispensable helper for its synthesis, and that hyaluronic acid is the key to deep hydration. Each of the three plays its own part in your skin.
