How to Boost Collagen and Elastin for Firmer, Healthier Skin

Collagen and elastin are the foundations of firm, resilient, youthful-looking skin. Discover how summer sun exposure accelerates collagen breakdown and how advanced skincare, SPF and regenerative treatments can help support your skin’s natural repair processes.

Summer Skin: Collagen and Elastin

Collagen vs elastin : Strength and Elasticity

Collagen and elastin are two of the most abundant structural proteins in the human body. Collagen fibres provide strength, firmness, and support for the skin, muscles, bones, tendons, ligaments, and connective tissues. Elastin fibres provide and recoil, allowing tissues such as skin, lungs, and blood vessels to return to their original shape after movement.

Collagen and elastin are produced by specialised cells called fibroblasts, which are found in the dermis – the middle layer of human skin. Think of collagen as the strong woven fabric of a trampoline, while acts like the elastic bands around the edge – allowing our skin to bounce back after every smile, laugh and facial expression.

Hyaluronic acid is found naturally in both the epidermis and the dermis, filling the space between cells to provide structural integrity, skin hydration, volume, and .

Collagen and elastin production

In young skin, fibroblasts are highly active, continually creating new skin cells and breaking down and rebuilding collagen. As children, the high quantity of collagen and elastin the skin results in radiant skin with natural plumpness and resilience. As we age – due to natural processes, fibroblasts become less active and production of collagen and elastin declines. From our mid-20s onwards, collagen gradually declines by around 1% each year. Existing collagen fibres become shorter and weaker, and elastin networks become brittle and fragmented. Over time this contributes to signs of ageing via fine lines, wrinkles, sagging skin, reduced skin elasticity, skin laxity and crepey skin. This is why many advanced cosmetic skincare products and in‑clinic treatments try to stimulate collagen production. The goal to boost collagen and elastin is ever present in the world of aesthetics and beauty.

Elastin and Collagen – Lifestyle and Environmental Damage

Lifestyle factors such as smoking, alcohol consumption, poor nutrition, chronic stress and inadequate sleep all contribute to accelerated collagen breakdown and slower skin repair. But the biggest lifestyle culprit  for lower levels of collagen and elastin in your skin is sun exposure. Excessive exposure to sun causes significant damage to the properties of the skin and moves you further away from the goal of beautiful skin.

UVA, UVB and UVC are types of light emitted by the sun. Of these three, UVA is the lowest energy type of light, whereas UVC is the highest energy light. UVC is so powerful and destructive that it would be fatal to life on earth so luckily, all UVC light is blocked by the earth’s ozone layer at about 35 KM above the earth. Most UVB light is also blocked by the ozone layer, so of the sun light that reaches earth, about 95% is UVA and 5% is UVB. 

UVB rays primarily affect the epidermis (the outer layer of the skin), triggering the production of melanin skin pigment. This leads to tanning — and, when excessive, damaged skin or sunburn. More melanin in the skin results in a darker skin tone.

UVA deep into the dermis, where it generates free radicals – unstable molecules that damage healthy skin cells and weaken collagen and elastin fibres. This process, known as oxidative stress, gradually breaks down the skin’s support structure and reduces its ability to repair itself, making UVA the leading cause of skin ageing know as photo-ageing.

While we cannot stop the natural ageing process, we can influence how our skin ages by supporting the activity of fibroblasts — the cells responsible for producing collagen and . The key to maintaining stronger, healthier skin is protecting existing from damage while encouraging the skin’s natural repair and renewal .

A combination of daily medical-grade skincare, consistent sun protection, healthy lifestyle choices and evidence-based aesthetic treatments can help collagen synthesis, improve skin quality and support a firmer, more resilient complexion. Treatments such as microneedling, LED phototherapy and injectable biostimulators including Profhilo and Sculptra work in different ways to activate the skin’s regenerative processes, helping to improve hydration, texture, elasticity and overall skin health over time.

To protect the skin, dermatologists recommend avoiding peak sun hours (10:00–16:00) and applying a broad‑spectrum SPF 50 daily – even on cloudy days. should be reapplied every 2 hours especially if you are sweating, exercising, or swimming. At LPA we always ask, before we begin to address your loss of collagen and elastin, what are you doing to protect your skin each day and how do you plan to maintain and prevent signs of skin aging. 

Anti-ageing Skin care and how to boost collagen

Several evidence‑based treatments can stimulate Collagen production and improve skin firmness:

– creates controlled micro‑injuries that trigger the skin’s natural healing response. 3 – 6 treatments a year help to stimulate native elastin and collagen, improve skin texture and help keep your skin firm. This treatment can be supercharged by adding as a serum used during treatment for maximum absorption into the skin layers, enhancing skin health.

– uses specific wavelengths of light to support cellular repair and collagen synthesis. This ‘no downtime’ is suitable for all skin types including sensitive skin. Providing a source of energy for your skin cells, this treatment helps to keep your skin healthy during summer and winter by strengthening the skin barrier.

Injectable biostimulators such as   and Sculptra- hydrate the skin deeply and stimulate collagen and elastin production over time. Unlike traditional dermal fillers which simply add volume, biostimulators actively bio-remodel the skin’s from within for a highly natural, hydrated result whilst increasing collagen in your skin and elastin synthesis. Glowing skin can be encouraged and maintained by a medical skin care inclusive of a stable vitamin c serum, skin protection in the form of  SPF and high quality collagen supplements such as Totally Derma.

Frequently Asked Questions: Collagen, Elastin and Skin Ageing

Yes. UV exposure, particularly UVA rays, is one of the biggest contributors to premature skin ageing. UVA penetrates into the dermis where collagen and elastin fibres are found, creating oxidative stress and enzymes that break down the skin’s structural proteins. Over time, this can contribute to fine lines, wrinkles, reduced and skin laxity.

The skin has an impressive ability to repair itself, but damaged collagen cannot simply be replaced . The aim of skin is to protect collagen while stimulating fibroblast activity and encouraging the production of new, healthier collagen. Daily SPF, medical-grade skincare and evidence-based treatments can all play a role in supporting this process.

Several treatments can encourage collagen synthesis by activating the skin’s natural healing response. Microneedling creates controlled micro-injuries that stimulate fibroblast activity, while LED phototherapy supports cellular function and skin repair. Injectable biostimulators such as Profhilo and work within the skin to promote collagen production and improve skin quality over time.

Profhilo is an injectable hyaluronic acid-based treatment designed to improve skin and stimulate the skin’s regenerative processes. It encourages the production of collagen and elastin, helping to improve skin firmness, elasticity and overall skin quality rather than simply adding volume like a traditional dermal filler.

Collagen gradually begins to decline from our mid-20s onwards, decreasing by approximately 1% per year. This process is influenced by intrinsic ageing as well as external factors such as UV exposure, smoking, stress, nutrition and lifestyle choices.

The most step is daily broad-spectrum SPF 50, applied generously and reapplied when needed, particularly after swimming, sweating or prolonged sun . Wearing protective clothing, seeking shade during peak UV hours and maintaining a consistent skincare routine can also help protect your skin’s collagen and elastin networks.

Skin health is built from the inside out. While ageing and ageing signs are  natural, protecting your skin’s structural proteins from UV damage and stimulating fibroblast activity can help you maintain a firm, resilient, and complexion.
