Collagen Treatment
Over time, our natural collagen levels begin to decline — typically from the age of 25 — leading to visible signs of ageing such as fine lines, skin laxity, and a loss of volume and radiance. Collagen is the essential structural protein that keeps our skin smooth, firm, and resilient. At rtwskin in Tunbridge Wells, we offer advanced collagen treatments designed to reverse these effects through targeted biostimulation and rejuvenation.

One of the innovative methods we occasionally use in the clinic is Karisma Collagen Injections, a biostimulator that supports collagen regeneration using hyaluronic acid and recombinant type I collagen.
One of the formulations we offer is Karisma, a non-crosslinked collagen biostimulator made with recombinant type I collagen, hyaluronic acid, and carboxymethyl cellulose. It’s particularly suited for patients who want visible rejuvenation with minimal volume change. This type of collagen support provides hydration, firmness, and subtle lifting without the heaviness of traditional fillers.
Unlike traditional dermal fillers, collagen therapies focus on long-term restoration of your skin’s natural support system. Collagen treatments work by triggering the body’s own healing response and encouraging fibroblasts to regenerate lost collagen fibres. This is ideal for anyone seeking visible yet natural improvement in skin quality and firmness without altering facial structure.
Our treatment options include:
Collagen injections with biostimulatory action
Collagen induction therapy (microneedling techniques)These procedures help improve hydration, stimulate new tissue production, and reinforce the skin’s structural integrity — making them especially effective for patients in their late 30s to 60s. They’re particularly beneficial for improving skin elasticity and promoting long-term firmness.
This form of rejuvenation collagen therapy not only targets early signs of ageing but also supports the skin’s ability to regenerate and maintain youthful resilience over time.
Whether you’re looking to target mild volume loss or are after more advanced anti-ageing benefits, collagen therapy provides a safe, non-surgical pathway to healthier, plumper, and more elastic skin.

How It Works
Our approach to collagen rejuvenation is grounded in skin biology. When collagen stimulating treatments like biostimulator injections are introduced into the dermis, they activate fibroblasts — the cells responsible for producing new collagen and elastin.
This process of neocollagenesis continues over several weeks following the treatment, delivering gradual, natural improvements to skin density, tone, and elasticity. Some collagen therapies use polynucleotides, while others combine collagen with hyaluronic acid for added hydration.
Karisma collagen injections stimulate natural collagen production and improve skin structure. When combined with treatments like Mesotherapy and PRP (Twilight Therapy), they work synergistically to enhance skin rejuvenation by improving absorption and boosting overall results.

Is this treatment right for me?
If you are looking to smooth and firm your skin, or reduce signs of ageing while regenerating, hydrating, and repairing your complexion, then collagen induction therapy is perfect for you. This treatment is designed for the medium-term correction of facial skin defects caused by ageing and loss of volume, making it best suited for patients wishing to reduce imperfections in the skin of the face or lips. It is also an excellent option for improving small scars, such as those caused by acne.
How many treatments will I need?
We recommend a second treatment four weeks after the first, followed by a top-up every 3-4 months for optimal, long-lasting results. Combining collagen threading with our biostimulator injections or Skin Boosters enhances effectiveness, providing outstanding results. Additionally, pairing collagen injections with Mesotherapy and Ellanse can further amplify rejuvenation effects, addressing skin texture and volume loss for a more comprehensive approach to anti-ageing.

A single treatment costs £350, or you can purchase a course of two treatments for £650. The collagen injections cost reflects the quality and longevity of results you can expect. Investing in these treatments is not just about immediate results; it’s about long-term skin health and vitality
