Collagen is the most abundant protein in the human body — it makes up about 75% of skin's dry weight and is the primary structural protein responsible for skin's firmness, resilience and youthful appearance. Understanding why it declines and what genuinely stimulates new production is essential to making informed decisions about skincare and professional treatments.
Why Collagen Production Slows
Collagen decline begins in our mid-twenties, accelerating in women during and after menopause due to oestrogen loss — oestrogen directly stimulates collagen synthesis. UV radiation is the single biggest external factor: it generates free radicals that degrade collagen fibres and inhibit new production. Smoking, high-sugar diets (which cause glycation — collagen cross-linking that makes it brittle), pollution and chronic stress all accelerate the process further.
What Actually Works
Topical collagen creams do not work — collagen molecules are too large to penetrate the skin. What does work topically: vitamin C (an essential cofactor for collagen synthesis), retinoids (professional-strength retinoic acid most effectively), and peptides that signal fibroblasts to produce more collagen.
At iluexpert, we stimulate new collagen through several different mechanisms. Dermapen Microneedling triggers the wound-healing cascade — controlled micro-injury prompts the skin to produce new collagen and elastin as it heals. MANTIS VIXO uses pulsating magnetic fields to activate fibroblasts without heat or needles. MINTT 100 Real Fit Lifting uses dual-phase PCL thread technology to structurally stimulate progressive collagen production. And professional peels — particularly the TIMECODE Retinol Yellow Peel — accelerate cell renewal and collagen synthesis at a deeper level than any over-the-counter product can reach.
Collagen Supplements: The Evidence
Hydrolysed collagen peptide supplements have become popular — and the evidence, while not conclusive, is more promising than critics suggest. Several randomised controlled trials show improved skin hydration, elasticity and reduced wrinkle depth with consistent use of 2.5–10g daily over 8–12 weeks. They work not because the collagen reaches your skin intact, but because the digested peptides signal the body to upregulate its own collagen synthesis.
The most effective approach combines consistent home care (vitamin C, retinoids, SPF), smart supplementation if appropriate, and professional treatments that directly stimulate collagen from the inside. If you are not sure where to start, a consultation at iluexpert will help us map out the right plan for your skin.
