What is Collagen?

Collagen is the most abundant protein in the human body. It acts as the building block for skin, muscles, tendons, and bones, providing strength, structure, and elasticity. In the skin, collagen contributes to firmness, hydration, and a plump appearance.

There are at least 28 types of collagen, but the majority of the body’s collagen belongs to:

• Type I – found in skin, bones, and tendons
• Type II – primarily in cartilage
• Type III – commonly found alongside Type I in skin and blood vessels

Why Does Collagen Decline?

As we age, collagen production begins to slow — typically starting in our mid-to-late 20s. This natural decline can lead to:

• Fine lines and wrinkles
• Skin laxity and sagging
• Loss of elasticity and firmness
• Slower wound healing

External factors such as UV exposure, smoking, stress, and poor diet can accelerate collagen breakdown.

Can Diet Support Collagen Production?

While topical or in-clinic interventions can help, collagen support starts with lifestyle. Nutrients that may help include:

• Vitamin C – Found in citrus fruits and peppers; crucial for collagen synthesis
• Zinc & Copper – Present in nuts and shellfish; aid in collagen cross-linking
• Proline & Glycine – Amino acids in bone broth, egg whites, and fish
• Antioxidants – From berries and leafy greens to protect collagen from oxidative damage

Topical Skincare Ingredients to Know

Certain skincare ingredients can support the skin’s own collagen-building process:

• Retinoids – May increase collagen production and skin renewal
• Vitamin C Serums – Help stabilize existing collagen and reduce breakdown
• Peptides – Signal the skin to regenerate proteins like collagen and elastin
• Broad-Spectrum Sunscreen – Essential to prevent UV-induced collagen loss

Clinical Options: Supporting Collagen from Within

For patients looking to address visible signs of collagen loss, there are doctor-led options that stimulate deeper skin layers. At Cambridge Medical Group, possible treatments may include:

• Ultrasound-Based Technologies – Such as HIFU (High-Intensity Focused Ultrasound) which uses sound waves to reach the deeper dermis and encourage collagen production
• Radiofrequency (RF) Treatments – Use thermal energy to support skin tightening and collagen remodeling
• Laser-Based Therapies – Designed to activate new collagen formation by delivering energy to targeted layers of the skin

These options are often part of a broader treatment plan, based on a doctor’s evaluation of your skin goals and current condition.

Why a Doctor’s Consultation Matters

Skin structure varies between individuals. The best approach to collagen restoration should always be tailored. At Cambridge Medical Group, doctors conduct a full facial and skin assessment to create a safe, structured plan for healthier, firmer-looking skin.
