Aging skin, fine lines, and volume loss are common skin concerns for many beauty-conscious people. These issues can be addressed by collagen-stimulating injections and dermal fillers. However, choosing between the two options is challenging. That is particularly because each treatment addresses specific concerns with unique applications.
Fortunately, Dr Michael O’Gorman offers an expert approach to both options. Therefore, if you are new to cosmetic injections, here is a detailed guide to help you choose the right procedure.
All you need to know about collagen-stimulating injections
What are collagen-stimulating injections?
Collagen stimulating injections or biostimulators are cosmetic procedures that use biocompatible substances to improve collagen production. The injections use Poly-L-Lactic acid (PLLA) or calcium hydroxylapatite (CaHA). When injected, these substances offer a long-lasting and natural way to boost the body’s collagen and elastin levels. This improves skin texture and elasticity.
Do collagen-stimulating injections really work?
Clinical results and patient feedback show clear improvements in skin texture, firmness, and volume after using collagen-boosting injections. Most people also report a more youthful appearance that lasts longer than hyaluronic acid-based fillers. That is because the injections:
- Stimulate fibroblasts to produce more collagen.
- Improve skin structure from within.
- Deliver a more gradual and natural-looking enhancement.
How long do collagen-stimulating injections last?
Collagen stimulation effects are not as immediate as most people expect. The improvements appear 2-3 months after injection and may require multiple sessions to achieve the desired outcome. However, the results can last up to five years, depending on the product used and the treated area.
What are the side effects of collagen-stimulating injections?
An injectable collagen stimulator is generally considered safe and a minimally invasive way to improve the skin’s appearance and texture. However, some patients report mild side effects, such as minor bruising, skin redness, rash with itching, swelling, and possible scarring. These effects are temporary and subside over time. A more significant side-effect is the development of nodules – these are essentially fibrous lumps under the skin which can be difficult to treat. Luckily, in the right hands and with the right injecting techniques, these are relatively rare. However, consulting a skilled practitioner is recommended to minimise potential risks.
Collagen-stimulating injections cost
Collagen injection cost varies based on the type and amount of products used, the number of sessions required, and treatment areas. Here is the breakdown according to Dr Michael’s pricing.
- 800 GBP for one vial.
- 1400 GBP for two vials.
- 2,000 GBP for three vials.
- 2,400 GBP for four vials.

All you need to know about dermal filler
What are dermal fillers?
These are cosmetic injections that combat signs of aging, volume loss, or sagging skin and improve facial symmetry and aesthetics. They utilise hyaluronic acid, a naturally occurring substance in the skin. This allows practitioners to use less quantity of dermal fillers than most procedures would require.
What are dermal fillers used for?
Dermal fillers are versatile and can treat various aesthetic concerns. These include:
- Defining the jaw.
- Treating fine peri-oral lip lines.
- Lip enhancement for a fuller look.
- Correcting under-eye hollows, dark circles, and tear troughs.
- Facial lifting.
- Hand rejuvenation.
- Scarring correction.
- Replacing lost volume in the mid-face region.
- Smoothing nasolabial and marionette folds.
How long does it take for fillers to work?
Unlike collagen fillers, dermal fillers provide immediate results. These volume-boosting injections can address specific concerns swiftly, offering instant smoothing effects. The effect improves further as the treatment settles in over a couple of weeks. The treatment effect is partly relating to structural skin support, to improved hydration, to volume replacement, and to new collagen production. This provides predictable outcomes in a single session, which takes 30-60 minutes.
How long do dermal fillers last?
Dermal filler results last from 6 months to a few years, depending on metabolism, target area, and product used. For instance, hyaluronic acid fillers last between 6 to 18 months. Other products like calcium hydroxylapatite (CaHA) can last up to two years.
What are the side effects of dermal fillers?
Dermal fillers, just like collagen boosting injections for the face, are generally safe with minimal risks. However, patients often report injection-related reactions that can resolve within 2 days or up to 2 weeks in rare cases. These include:
- Swelling and redness
- Bruising
- Tenderness at the injection site
Rare complications such as vascular occlusion have been reported worldwide. It is essential to have these treatments done within a medical setting, and with a practitioner who is equipped and who is knowledgeable in how to reverse and dissolve the product in the event of such a complication.
What do dermal fillers cost?
Dermal fillers cost 490 GBP per 1 ml for a standard area or 600 GBP per 1 ml for advanced areas. Advanced injection areas include the under-eye, nose, frown, temples, and chin. The cost can also vary depending on the brand of filler used, treated areas, and number of vials / syringes needed.

Collagen-Stimulating VS Dermal Fillers: Which is best for you?
Are you stuck between how to boost skin collagen and restoring lost volume? Both treatments offer the easiest and most innovative way to restore the skin’s natural and youthful appearance. However, they differ in their outcomes, application mechanisms, result longevity, and purpose. For instance, choose collagen-stimulating injections if:
- You prefer long-term improvements (12-24 months)
- You aim to boost skin quality and structure.
- You are not after immediate changes.
- Areas such as the temples or lateral face are your main concern.
Meanwhile, consider dermal fillers if:
- You want instant volume restoration and structural definition.
- You need quick but short-term results for an upcoming event.
- You are treating multiple facial and body areas.
- You are treating more delicate areas such as the under-eye or lips.
