As interest grows in treatments that improve skin quality from within, many patients ask Dr Ayad Harb, what are the benefits of collagen injections? Unlike traditional volumising dermal fillers, collagen injections, also known as biostimulating injections, are designed to stimulate the skin’s own regenerative processes, improving firmness, texture, and resilience over time rather than creating instant volume.
Dr Ayad explains that collagen injections work by encouraging the body to produce new collagen naturally. As we age, collagen levels decline, leading to thinner skin, loss of elasticity, and fine lines. Collagen-stimulating injectables act as a trigger within the dermis, prompting gradual collagen renewal that strengthens the skin’s structure from beneath the surface.
Rather than altering facial shape, these treatments focus on skin quality and integrity, making them ideal for patients who want subtle, natural-looking improvement.
One of the main benefits of collagen injections is increased firmness. As new collagen forms, the skin becomes more elastic and better supported, helping to reduce laxity and soften fine lines. Dr Ayad notes that this tightening effect develops progressively, giving results that look refreshed rather than overtreated.
This makes collagen injections particularly suitable for areas such as the face, neck, jawline, and under-eye region, where skin quality plays a key role in overall appearance.
Unlike treatments that provide immediate but temporary effects, collagen injections offer long-term improvement. Results build gradually over several weeks as collagen production increases, and benefits can last many months. Dr Ayad highlights that this slow progression is what makes the results look so natural; the skin simply appears healthier, smoother, and more resilient over time.
Dr Ayad explains that collagen injections can be used to address a wide range of concerns, including early signs of ageing, loss of skin density, fine lines, and crepey texture. They are also often used as part of a combined treatment approach alongside skin boosters, laser treatments, or energy-based devices to enhance overall skin regeneration.
According to Dr Ayad, the key benefits are stronger skin structure, improved firmness, better elasticity, and naturally progressive rejuvenation. Collagen injections don’t aim to change how you look; they aim to restore what the skin has gradually lost. When used thoughtfully, they offer a refined, long-term approach to skin ageing that supports healthier skin from the inside out.
Yes, collagen injections do work, but in a different way to traditional fillers. Rather than adding instant volume, they stimulate the skin’s natural collagen production over time. Dr Ayad explains that this leads to gradual improvements in skin firmness, elasticity, and texture, making the skin look healthier and more resilient. Results are subtle and progressive, which is why they’re often chosen by people seeking natural-looking rejuvenation rather than immediate change.
The effects of collagen injections typically last up to 12 months, depending on the product used, the area treated, and individual skin biology. While the injectable itself is gradually absorbed, the collagen it stimulates remains, supporting long-term skin quality. Dr Ayad notes that maintenance treatments may be recommended to sustain collagen levels, particularly as natural collagen production continues to decline with age.
