The unique power of TriSignal Collagen®: bioactive tripeptides
Tripeptides are the smallest and most bioactive form of collagen. Your body absorbs them directly: no detours and no loss. They arrive exactly where collagen is needed: in your skin, joints and hair.
- 99% absorption into the blood
Standard collagen: ± 40%
- Detectable in the blood in as little as 15 minutes
Faster acting than any other form of collagen
- No breakdown process needed
Your body can process the peptides directly
What does this change for you?More collagen exactly where you feel and see it: firmer skin, suppler joints and fuller hair.
Tripeptides supply collagen –and at the same time stimulate your own production
- Tripeptides supply your body with collagen and at the same time signal it to produce more on its own.
- Tripeptides bind directly to the skin cell receptor and activate the body's natural production there.
- Double effect: collagen from outside, plus new collagen produced by your own cells.
- No other type of collagen can do this. Only tripeptides work on both levels at once — which is what makes them so unique.
Natural hyaluronic acid
Production multiplied by 3.8 (clinically proven)
- 3.8x Stimulates the body's natural production of hyaluronic acid by a factor of 3.8 thanks to bioactive tripeptides.
- Less powder, same effectiveness
- GLOW25 COLLAGEN INTENSIVE
2.5 g is enough for a full effect - Thanks to the TriSignal Collagen Effect®, the tripeptides are so bioactive that one sixth of the usual amount is more than enough.

Hello, I'm Lea – Head of Brand at Glow25®
I'm delighted to show you how our collagen can help you feel fully yourself: radiant, strong and confident.
Glow25® was developed for and by women. Our collagen is for every woman who wants to support her body naturally and actively counteract the signs of ageing.
It keeps your skin smooth and radiant, makes your joints suppler and maintains the health and shine of your hair.
The result: you feel good in your own skin again, regain your confidence and are brimming with energy.
Why collagen really works
1. Collagen is a protein your body produces naturally. It forms the foundation, so to speak, that keeps your skin, hair, nails and joints firm and supple.
2. Until about the age of 25, your body produces enough collagen. After that, production slowly declines year by year.
3. By 40, you have roughly 60% of your original collagen left. By 50, it is less than half. In other words: the foundations of your skin keep getting weaker.
➜ By using collagen, you give your body back the building blocks it has lost over the years. This way you can slow down the natural breakdown and strengthen your skin from within.
Does collagen really work or is it just a marketing promise?
More than 37 studies by renowned scientists have examined and clinically proven the effectiveness of collagen.
➜ Proksch: Study of 69 women — after just 4 weeks, their skin was visibly firmer. (Skin Pharmacology and Physiology)
➜ Inoue: Study of 72 women aged around 50 — after 12 weeks, their skin was better hydrated and wrinkles had decreased. (Journal of Cosmetic Dermatology)
➜ De Luca: Study of 120 participants — after 90 days, wrinkles were visibly reduced and the overall skin texture improved. (Journal of Drugs in Dermatology)
This research shows that collagen is more than just a promise. It supports your skin, hair, nails and joints in a measurable way.
What makes Glow25 Collagen Intensive so powerful
The smallest form of collagen: for faster, more noticeable results
Glow25® contains bioactive tripeptides, the smallest and most effective form of collagen. This means your body can absorb and use them very quickly and in a targeted way, rather than having to laboriously digest large amounts of collagen. That is precisely the difference between simply taking collagen and actually getting it to where it is needed.
More hyaluronic acid from within: for visibly plumper skin
Tripeptides act as a signal in your body and can significantly increase the production of hyaluronic acid. This makes your skin plumper, smoother and visibly more radiant from within — exactly the effect many only expect from creams.
Easy to use
Thanks to its concentrated formula, 2.5 g per serving is enough. This makes Glow25® easy to fit into your daily routine, whether you dissolve it in a glass of water or in your cappuccino. No big glass of powder, no complications, just a simple habit that's easy to keep up even on the go.

How does Collagen Intensive differ from Glow25 Collagen or Collagen Plus?
While the original Glow25 collagen powder formulas are very effective, Collagen Intensive represents a step forward in absorption and effectiveness thanks to modern tripeptide technology.
The tiny tripeptides are so small (under 500 Daltons) that they can be detected in your bloodstream as early as 15 minutes after ingestion. This means faster, deeper-acting results, with even simpler use (just 2.5 g per stick per day, at home or on the go).
This makes Collagen Intensive the most powerful product in the Glow25 range.
Does Collagen Intensive also work in my morning coffee?
Yes! Glow25 spent months working on the formula to make sure the active ingredients stay effective in hot drinks. The tripeptides in Collagen Intensive are stable up to 90 °C, which makes them perfect for your morning coffee ritual.
What is the best way to take Collagen Intensive every day?
Open one stick every day and add it to your favourite drink. The powder is tasteless and dissolves quickly and easily in liquids. Most customers prefer to mix their daily collagen dose into:
- coffee or tea
- water
- juices
- smoothies
- soups, dressings, yoghurt or fromage frais
Are there really no known side effects?
No systematically known side effects have been identified in the available studies or in our own tests. The product undergoes strict safety and quality controls during manufacturing and is therefore well tolerated.
Of course, everyone is different. Some people feel unwell after eating certain foods or taking certain supplements. This is true of apples, bananas, wholemeal bread or broccoli, just as it is of magnesium, vitamin D or anything else.
That is why we ask you to listen to your body. If, against all expectations, you don't feel quite right with daily use, you can activate the guarantee and you will be fully refunded the price of the product.
Please note: As with any food supplement, we recommend consulting your doctor if you have a specific health condition. This also applies during pregnancy.
What if I'm already getting good results with my current collagen routine?
Collagen Intensive is designed to amplify and accelerate your current results. Imagine going from a good torch to a powerful floodlight: everything you already love about your routine simply becomes brighter and more powerful.
Is this product suitable for vegetarians/vegans?
Collagen Intensive contains collagen peptides from fish and is therefore suitable for pescatarians, but not for vegetarians or vegans. It is, however, free from:
- dairy products
- gluten
- added sugars
- artificial colours or flavourings
- genetically modified organisms (GMOs)
How does the satisfaction guarantee work?
You take zero risk with our 60-day money-back guarantee on all packs.
Whether you choose the 30-day, 2-month or 3-month pack, you can try Glow25 for 60 days. Not convinced by the product? The Glow25 team will refund your purchase price in full, quickly and without any hassle.
Glow25 stands for quality, effectiveness and trust.
