Collagen in Skincare
Collagen is the most abundant structural protein in the human dermis, providing the tensile strength, firmness, and elasticity that characterise young skin. From the mid-twenties onward, collagen production declines at approximately 1% per year and the structural collagen network becomes progressively disorganised by UV-induced fragmentation and reduced fibroblast activity.
The result is clinically observable: loss of skin firmness and elasticity, deepening fine lines and wrinkles, and progressive thinning of the dermal layer.
For topical application, what matters most is the distinction between intact collagen and hydrolyzed collagen peptides, the role of molecular weight in determining topical behaviour, and how the EVIK™ LyoPearl format delivers collagen peptides in a fresh, preservative-free, precisely dosed single-dose bead.

Not all collagen in skincare products works the same way. Molecular structure and peptide size are fundamental to understanding what a topical collagen product can and cannot do.
Intact Collagen Molecules
Native collagen has a molecular weight of 300,000 Da or higher. At this size, it cannot penetrate the stratum corneum and does not reach the dermis where fibroblasts and the extracellular matrix are located.
Primary topical role
Topically applied intact collagen acts as a film-forming humectant. It sits on the skin surface, reduces transepidermal water loss, and provides a temporary smoothing effect.
What it does not do
It does not stimulate collagen synthesis or fibroblast activity. The temporary plumping visible after application is a surface-film effect rather than a dermal response.
Hydrolyzed Collagen Peptides
Collagen hydrolysate is produced by enzymatic or acid hydrolysis of collagen into short peptide fragments. Molecular weight can typically range from 500 to 10,000 Da depending on the degree of hydrolysis.
Low molecular weight peptides
Peptides under approximately 2,000 Da have demonstrated greater potential for penetration into skin layers and interaction with fibroblast-associated pathways.
Key peptide sequences
Pro-Hyp and Gly-Pro-Hyp are among the peptide sequences investigated for their interactions with dermal fibroblasts and extracellular matrix activity.
Clinical Evidence for Collagen Peptides
The evidence base for collagen peptides includes both oral supplementation studies and topical application research. For formulation science, these studies provide context for peptide activity, skin hydration, elasticity, wrinkle appearance, and extracellular matrix pathways.
Fibroblast Stimulation & Collagen Synthesis
Hydrolyzed collagen peptides — including Gly-Pro-Hyp and Pro-Hyp — have been investigated for their interaction with dermal fibroblasts and their potential to influence collagen, elastin, and hyaluronic acid production.
A 2024 systematic review in Nutrients covering eleven studies reported fibroblast responses to hydrolyzed collagen and highlighted greater bioavailability associated with lower molecular weight collagen preparations.
A 2022 in-vitro study by Brandao-Rangel et al. investigated collagen peptide effects on fibroblast and keratinocyte proliferation alongside inflammatory cytokine responses.
Hydration, Elasticity & Wrinkle Appearance
A 2023 randomised, double-blind, placebo-controlled study in Food & Function involving 100 women aged 30–60 reported improvements in skin hydration, desquamation, elasticity and wrinkling following collagen peptide use.
A 2024 six-week randomised controlled trial reported improvements in wrinkle measurements and skin moisture with low-molecular-weight collagen peptides compared with placebo.
A 2024 clinical trial using high-resolution ultrasound reported changes in collagen content within the papillary dermis following hydrolyzed collagen use.
Topical Delivery & Molecular Weight
The stratum corneum represents the primary barrier to topical delivery. High molecular weight intact collagen is generally too large to cross this barrier.
Research using skin penetration techniques has demonstrated that smaller collagen peptide fragments can reach deeper skin layers.
Recent research has also investigated low-molecular-weight recombinant collagen peptides and their effects on fibroblast extracellular matrix pathways following topical application.
Hyaluronic Acid Co-Synthesis
Collagen peptide research has also examined effects beyond collagen production, including potential stimulation of hyaluronic acid and elastin synthesis in dermal fibroblasts.
Pro-Hyp has been investigated for its ability to stimulate hyaluronic acid production in dermal fibroblasts.
This creates a complementary formulation concept for EVIK™ LyoPearl Collagen, where collagen peptides and sodium hyaluronate are delivered together.
Source Matters
Collagen peptides can be sourced from several origins, each with different amino acid profiles, peptide characteristics and compatibility considerations.
Marine
Predominantly Type I collagen from fish skin and scales. Marine collagen preparations are commonly available in lower molecular weight forms and are widely investigated for skin applications. Not suitable for individuals with fish allergy.
Bovine
Predominantly Types I and III collagen. Bovine collagen is widely used and well represented in collagen research. It may not be suitable for vegetarian or certain religious or dietary requirements.
Porcine
Porcine collagen has a profile broadly similar to bovine collagen and is used in a range of collagen applications. It may not be suitable for certain religious or dietary restrictions.
Vegan / Recombinant
Biosynthetically produced collagen-like peptides or collagen-stimulating peptides are increasingly available. The evidence base for topical applications continues to develop.
Why Freeze-Dried Format for Collagen Peptides?
Collagen peptides can present stability and preservation challenges when incorporated into aqueous formulations. The lyophilized bead format separates the dry active formulation from the aqueous phase until the point of use.
-
No preservatives
Without water, microbial growth is not possible within the dry bead, reducing the need for a preservative system in the bead formula. -
Protected bioactivity
Collagen peptides are stored in dry form until dissolution, helping protect the formulation from degradation associated with prolonged exposure to an aqueous environment. -
Fresh dose every use
Each bead is designed to deliver a precisely measured quantity of collagen peptide formulation. -
Collagen + HA co-delivered
Collagen peptides and sodium hyaluronate are lyophilized together for simultaneous delivery. -
Ambient stable
The dry format is designed for ambient-temperature storage, supporting travel, retail and e-commerce distribution.
