Collagen VII forms specialised anchoring fibrils at the dermal–epidermal junction—the important interface where the epidermis meets the dermis. These fibrils extend from the epidermal basement membrane into the underlying dermal matrix, helping to secure the two layers together. This structural connection contributes to skin cohesion, strength, resilience and resistance to mechanical stress. With ageing and cumulative photodamage, the dermal–epidermal junction becomes flatter and less structurally robust. Collagen VII and other supporting proteins may become reduced or disorganised, contributing to thinner, more fragile skin with diminished firmness and resilience.
SkinCeuticals Collagen Pro-Solution is designed to act on collagen-related pathways associated with this important area of the skin. Its biosimilar collagen polypeptide and multi-peptide technology are intended to support the skin’s natural collagen network, including collagen associated with the dermis and the dermal–epidermal junction. It is important to explain the action accurately: the serum does not physically deliver complete collagen VII fibrils through the skin or directly replace lost anchoring structures. Rather, it is formulated to support biological signalling and the skin’s own collagen-related processes, helping improve the visible signs associated with collagen decline.
This makes Collagen Pro-Solution particularly relevant for concerns such as:
- Reduced skin firmness and elasticity
- Loss of bounce and resilience
- Fine lines and early laxity
- Thinner-looking or less structurally supported skin
- Changes associated with deterioration of the dermal–epidermal junction
The most effective strategy combines Collagen Pro-Solution with a SkinCeuticals morning antioxidant and daily broad-spectrum sunscreen. The antioxidant helps limit oxidative stress, sunscreen reduces ongoing UV-driven collagen degradation, and Collagen Pro-Solution supports visible correction and collagen-related renewal.
Client explanation
Collagen VII acts like part of the anchoring system that holds the upper and deeper layers of the skin together. As we age, this junction becomes weaker and flatter. SkinCeuticals Collagen Pro-Solution is specifically designed to support collagen-related activity within this structural area, helping improve firmness, resilience and the visible signs of collagen decline. It does not simply place collagen on the surface—it supports the skin’s own biological processes. There is no single product, treatment or supplement that can stop collagen ageing. Healthy collagen depends on reducing its breakdown while supporting its natural production. The most effective strategy combines science-backed skincare, daily sun protection, professional treatments, excellent nutrition, healthy lifestyle habits and, where appropriate, evidence-based oral collagen supplementation. This holistic approach helps preserve skin structure, improve resilience and support healthier skin for longer. Healthy collagen is protected and supported through multiple complementary approaches:

COLLAGEN AND AGEING- The Science of Collagen Loss, Lifestyle and Nutritional Support
Collagen is the most abundant protein in the human body, accounting for around 30% of total body protein. It provides strength, structure and resilience to the skin, bones, tendons, ligaments and blood vessels. In the skin, collagen acts as the body’s natural scaffolding. Together with elastin, hyaluronic acid and other extracellular matrix proteins, it maintains firmness, elasticity and hydration. Unfortunately, collagen production is not constant throughout life. From our mid-twenties onwards, the balance gradually shifts from collagen production to collagen breakdown. Understanding why this happens is fundamental to developing an effective anti-ageing strategy.
What Happens to Collagen as We Age?
From approximately 25 years of age:
- Collagen production begins to decline by around 1% per year.
- Fibroblasts (the cells responsible for producing collagen) become less active.
- Existing collagen fibres become fragmented.
- Elastin fibres lose elasticity.
- Hyaluronic acid production declines.
- The dermal-epidermal junction gradually flattens.
- Skin becomes thinner and less resilient.
These changes occur naturally (intrinsic ageing) but are dramatically accelerated by environmental factors (extrinsic ageing).
Intrinsic vs Extrinsic Ageing
Intrinsic ageing is genetically programmed and unavoidable. Extrinsic ageing results from lifestyle and environmental exposure. Major contributors include:
- Ultraviolet radiation
- Smoking
- Air pollution
- Poor nutrition
- Chronic inflammation
- High sugar intake
- Sleep deprivation
- Chronic psychological stress
- Excess alcohol
- Physical inactivity
Research suggests that up to 80% + of visible facial ageing is caused by environmental exposure rather than chronological age alone.
Why Does Collagen Decline?
1. Fibroblasts Slow Down
Fibroblasts manufacture:
- Collagen
- Elastin
- Hyaluronic acid
- Fibronectin
With age they become less metabolically active. They produce:
- Less collagen
- Lower quality collagen
- Slower wound repair
- Reduced extracellular matrix support
2. Matrix Metalloproteinases (MMPs)
MMPs are enzymes responsible for breaking down damaged collagen. They are essential for normal tissue remodelling. However excessive activation causes accelerated collagen destruction. MMP activity increases following:
- UV exposure
- Smoking
- Pollution
- Inflammation
- Oxidative stress
This explains why prevention is just as important as stimulation.
3. Oxidative Stress
Every day our skin is exposed to free radicals generated by:
- UV radiation
- Visible light
- Infrared radiation
- Pollution
- Smoking
- Chronic inflammation
Free radicals damage:
- DNA
- Cell membranes
- Lipids
- Proteins
- Collagen
This is why antioxidants form the first pillar of SkinCeuticals’ philosophy.
4. Glycation
One of the least appreciated causes of skin ageing is glycation.
When blood sugar levels remain elevated, excess glucose attaches to collagen fibres.
These modified proteins become Advanced Glycation End Products (AGEs).
AGEs make collagen:
- Stiffer
- Less elastic
- More brittle
- More resistant to normal repair
They also stimulate inflammation and oxidative stress.
Clinically this contributes to:
- Sagging
- Yellowing skin
- Deep wrinkles
- Loss of elasticity
Oestrogen has a profound influence on collagen production.
During menopause:
- Collagen loss accelerates.
- Skin becomes thinner.
- Hydration declines.
- Wound healing slows.
- Elasticity decreases.
Studies suggest women may lose up to 30% of skin collagen during the first five years after menopause, with continued gradual decline thereafter.
Can We Replace Lost Collagen?
No. Applying collagen directly to the skin cannot rebuild the dermis because collagen molecules are too large to penetrate intact skin. Instead we aim to:
- Protect existing collagen.
- Stimulate fibroblasts.
- Reduce collagen breakdown.
- Support collagen synthesis.
- Improve skin repair.
1. Daily Antioxidants
Vitamin C remains the most extensively researched topical antioxidant.Benefits include:
- Neutralising free radicals
- Supporting collagen synthesis
- Reducing oxidative stress
- Improving photoprotection when combined with sunscreen
This is why SkinCeuticals recommends morning antioxidant protection every day.
2. Sunscreen
- Reduce MMP activation
- Prevent DNA damage
- Reduce pigmentation
- Preserve collagen
- Slow visible ageing
3. Retinoids
Retinoids remain the gold standard topical ingredient for collagen stimulation.They:- Increase collagen synthesis
- Reduce collagen degradation
- Improve epidermal renewal
- Improve skin texture
- Improve pigmentation
4. Professional Treatments
Professional procedures stimulate controlled repair.Examples include:- Microneedling
- Radiofrequency
- Fractional RF
- Laser treatments
- Chemical peels
- LED photobiomodulation
5. Nutrition
Collagen cannot be produced without adequate nutrition.Fibroblasts require:Protein
Provides amino acids including:- Glycine
- Proline
- Lysine
- Fish
- Poultry
- Eggs
- Dairy
- Lean meat
- Beans
- Lentils
Vitamin C
Essential for collagen synthesis.Sources:- Citrus fruit

Most tissue repair occurs during sleep.Poor sleep increases:
- Cortisol
- Inflammation
- Oxidative stress
Chronically elevated cortisol reduces collagen synthesis.Stress also increases inflammation and oxidative damage.Avoid Smoking
Smoking dramatically accelerates:

- Vasoconstriction
- Oxidative stress
- Collagen destruction
- Hydrolysed marine collagen peptides
- Vitamin C
- MSM (methylsulfonylmethane)
- L-lysine
- L-carnitine
