Liquid, peptide-based, blueberry-flavoured—why is this bottle of collagen syrup the better choice?

Do you apply a thousand-yuan face cream and use expensive serums every day, yet your skin remains dry, dull and riddled with fine lines?

Do you keep switching hair conditioners, yet your hair is still split and brittle, and your nails are so thin they crack at the slightest touch?

It’s not that you’re not trying hard enough; rather, you may have overlooked a crucial fact—ageing and wear and tear begin from within the body. Topical treatments can only provide ‘quick fixes’, whilst internal nourishment addresses the ‘root cause’.

But what’s even more disheartening is this: even if you start taking collagen supplements, if the molecules are too large or the formulation is incorrect, the vast majority of what you consume will simply ‘pass straight through’ your system, never reaching the dermis of your skin, let alone nourishing your hair and nails.

Collagen ≠ effective supplementation. Only ‘peptide’-grade collagen is a form that the body truly recognises and can actually utilise.

DUOZI Multi Collagen Peptides Syrup was created precisely to address this pain point of ‘ineffective supplementation’.

As we age and the pressures of daily life increase, our bodies naturally lose collagen at a rate of approximately 1 per cent per year. When the skin begins to look dull, fine lines start to appear and hair becomes brittle, replenishing collagen becomes a crucial step for modern people in maintaining their well-being. However, ‘how to replenish it’ and ‘what to replenish’ are often more important than ‘whether to replenish it’ at all.

Why do we need to supplement with collagen?

Collagen is the most abundant protein in the human body, accounting for 25–35 per cent of total body protein mass; it is often referred to as the ‘architect of the human body’, supporting skin elasticity, bone strength and joint health.

However, natural collagen, with its large molecular structure and a molecular weight exceeding 100,000 daltons, is difficult for the body to absorb directly and effectively. Although traditional dietary sources such as pig’s trotters and chicken feet are rich in collagen, most of it is broken down into individual amino acids during digestion, making it difficult for the intact collagen to reach target tissues such as the skin and joints; furthermore, consuming these foods involves a high intake of fat.

Collagen Peptides: A Smarter Way to Supplement

Collagen peptides were developed precisely to address this challenge. Using enzymatic hydrolysis, they ‘break down’ large collagen molecules into shorter chains of amino acids with a lower molecular weight—namely, peptides.

Compared with ordinary collagen, collagen peptides have a low molecular weight (typically between 500 and 10,000 daltons). They can be directly absorbed by the small intestine in the form of dipeptides and tripeptides, entering the bloodstream where they act as signalling molecules to stimulate fibroblasts to produce new collagen and hyaluronic acid, rather than simply serving as raw materials. Clinical studies have also shown that supplementing with collagen peptides has a positive effect on improving skin hydration and elasticity, as well as alleviating joint pain.

DUOZI Multi Collagen Peptides Syrup is based precisely on this scientific principle; through a hydrolysis process, it converts collagen into highly bioavailable peptides, ensuring that every drop is more readily utilised by the body.

Why choose a syrup (liquid) formulation?

Compared to powders or capsules, DUOZI has opted for a liquid syrup formulation for three main reasons:

Faster absorption: Liquid supplements bypass the disintegration and dissolution processes, entering the digestive system directly. Comparative studies show that blood levels of collagen peptides reach their peak within two hours of taking liquid collagen, indicating a faster absorption rate than solid formulations.

Better user experience: With a delicious blueberry flavour that is refreshing and pleasant to drink, it eliminates the fishy odour or difficulty in swallowing that may be associated with traditional collagen products. Just a small sip each day makes supplementation effortless.

Synergistic formulation: The liquid form facilitates the blending of additional active ingredients, allowing the various nutrients to blend more evenly and work together to provide nourishing benefits.

More Than Just Beauty: Comprehensive, Multi-Faceted Support

DUOZI Multi Collagen Peptides Syrup combines multiple types of collagen peptides, designed to provide comprehensive support that goes beyond the skin:

Nourishes healthy hair and nails: Provides nutritional support for keratin structures, helping to reduce breakage and strengthen hair and nails.

Smooths fine lines and combats early signs of ageing: Promotes the skin’s own collagen synthesis, supports the anti-ageing process and improves fine lines on the face.

Deeply hydrates and brightens dull skin: Increases moisture levels in the dermis, reduces dryness and dullness, and restores the skin’s natural radiance.

DUOZI’s new liquid multi-peptide collagen syrup is now officially available. Taken once a day, every sip is a convenient investment in beauty and vitality.
