When starting collagen-stimulating treatments, also known as biostimulator injections, one of the most common questions Mo Harb hears is, What are the 5 signs that collagen is working? Unlike treatments that create instant change, collagen regeneration happens gradually. The results are subtle at first, but when you know what to look for, the improvements become clear and long-lasting.
One of the earliest signs collagen is working is a noticeable increase in skin firmness. Mo Harb explains that as new collagen fibres form, the skin develops stronger internal support. This often shows up as skin that feels more resilient and less thin or fragile, particularly in areas like the cheeks, jawline, and under-eyes.
As collagen rebuilds, the surface of the skin begins to look smoother and more refined. Fine lines soften, pores may appear less noticeable, and the skin feels more even overall. Mo Harb notes that this change often becomes noticeable a few weeks after treatment, once the skin’s renewal process is fully underway.
Another clear sign collagen is working is improved elasticity. Skin begins to bounce back more easily and appears gently lifted rather than sagging. This doesn’t happen overnight; it develops gradually as collagen strengthens the skin’s framework. The result is a fresher, more supported appearance without looking overtreated.
Collagen regeneration improves overall skin health, not just structure. Mo Harb explains that many patients notice their skin looks brighter, plumper, and more hydrated, even without changes to their skincare routine. This glow comes from improved circulation and a healthier dermal environment as collagen production increases.
Perhaps the most important sign that collagen is working is that results keep getting better. Unlike dermal fillers that peak early, collagen-stimulating treatments continue to deliver improvement for weeks or even months. Mo Harb highlights that patients often notice their skin looking better at three months than it did at three weeks, a key indicator that natural regeneration is taking place.
According to Mo Harb, firmer skin, smoother texture, improved elasticity, healthier glow, and progressive improvement are the strongest indicators that collagen stimulation is doing its job. These changes don’t transform the face overnight; instead, they restore strength and quality to the skin in a way that looks natural, balanced, and long-lasting. When collagen is working, the skin doesn’t look “done”; it simply looks healthier.
Yes. Once collagen production is stimulated, the skin continues to remodel itself for several months. Even after the injectable or supplement is metabolised, the collagen it triggers remains, supporting longer-term skin quality. This is why collagen-based treatments are often described as regenerative rather than temporary.
The frequency depends on the treatment type and individual skin needs. Injectable collagen-stimulating treatments are often repeated every 9 to 12 months, while maintenance may be recommended sooner depending on age, skin condition, and lifestyle. A personalised review ensures collagen levels are supported without overtreatment.
