Hydroxyproline: the building block of your collagen
Collagen is often called the “protein of youth” – a key element for maintaining firm, smooth and vibrant skin. But what often remains in the shadows is how exactly this collagen is built and what determines its quality. This is where hydroxyproline comes into play – a specific amino acid responsible for the strength and stability of collagen fibers, and a direct participant in maintaining the tone, elasticity and resilience of the skin.
During the summer months, the need for quality collagen synthesis increases significantly. The reasons are well known – increased UV radiation, water loss, oxidative stress and thermal stress. All these factors contribute to the destruction of the collagen network and slow down the body's natural regenerative processes. It is then that the first signs of damage appear – dryness, fine lines, a grayer complexion and loss of firmness.
What makes hydroxyproline so special?
Hydroxyproline is a derivative of proline, an amino acid that undergoes enzymatic modification in the presence of vitamin C and iron to become an active, stabilizing ingredient. This transformation makes it possible to create strong and resilient collagen spirals that give skin its firmness and resistance to stretching and aging.
What’s even more interesting is that hydroxyproline doesn’t just play a role in synthesis—it serves as a biomarker for collagen health . When its levels are low in the body, it usually means that there is either a slowdown in collagen synthesis or an accelerated breakdown of collagen fibers. This is especially true in situations of chronic stress, sun exposure, or inadequate intake of protein and key nutrients.
Summer and the need for support from within
Sunny days, although invigorating, carry their own risks. UVA and UVB rays penetrate the dermal layer, where collagen fibers are located. They cause oxidative stress and activate enzymes that destroy the collagen structure. Over time, this leads to sagging skin, the appearance of wrinkles and the loss of natural protection against external aggressors.
Additional intake of hydroxyproline during this period not only helps repair damaged fibers, but also accelerates the formation of new ones , thus creating a natural buffer against photoaging. In combination with hyaluronic acid and antioxidants, hydroxyproline acts as a complete system to strengthen the skin, increase its moisture content and prevent thinning and sagging.
Product selection for optimal effect
To be effective, hydroxyproline must be part of a well-balanced formula that also includes other key amino acids – glycine, proline , as well as hyaluronic acid, zinc and coenzyme Q10 . All of these ingredients work together to nourish not only the skin, but also the hair, nails and connective tissue.
Zia Glow is a product created with this very purpose – to provide the body with everything it needs for effective collagen synthesis, resistance to UV stress and optimal cellular repair. Thanks to highly digestible hydrolyzed collagen and added hydroxyproline, Zia Glow provides not only beauty, but also deep biological support.
Its regular use during the summer keeps the skin hydrated, elastic and visibly fresher - even on days with the most intense sun.
