Instead of filling it in, we prompt your skin to produce collagen for itself.
We give the skin one instruction: “make it yourself”. We give the skin one instruction:
“make it yourself”.
A planned foreign-body response
The principle behind collagen-stimulating injections is simple.
Place a slowly dissolving substance (biodegradable ingredients such as PCL and PLLA) into the skin,
and the body reads it as a “stimulus”. Cells respond to that stimulus by starting to produce collagen.
The substance itself eventually disappears — only the collagen your body made remains.
STEP 01
A dissolvable substance goes into the skin
Biodegradable ingredients such as PCL and PLLA are injected to a set depth.
STEP 02
The body reads it as a “stimulus”
A planned foreign-body response begins, within a controlled range.
STEP 03
The collagen-making cells get to work
Fibroblasts — the skin’s collagen factories — are activated.
STEP 04
The substance disappears over months
It is metabolised by the body, leaving no residue.
STEP 05
Only the collagen you made remains
Elasticity and density build up over several months.
There comes a point when, rather than an urge to fix something right now, you simply feel like preparing slowly, starting today.
Collagen Boost is the approach built for that feeling.
Endlessly topping up with filler feels like a burden
My skin seems thinner as the years pass
I feel I should start something now
My friends are having injections — I don’t know where to start
Collagen production starts to fall from around the age of 20.
And it isn’t only ageing — sunlight, hormones and inflammation change the speed of the decline itself.
-1% / year
Natural decline
From age 20, it falls steadily by about 1% a year.
-30% / year
First 5 years after menopause
Hormonal change accelerates the loss of skin collagen.
UV
UV breakdown
Ultraviolet light breaks down the collagen in your skin directly.
Without UV protection, any regenerative treatment is only half as effective.
Taking your 20s as 100, this is what remains decade by decade.

Falling to less than half by your 60s
The reason results differ on the same injection is simple. However good the stimulus,
if the skin cells receiving it are worn out, collagen doesn’t get made well.
Before the performance of the injection comes the condition of your cells.
There are thousands of “collagen factories” in every square centimetre of skin. When those factories are exhausted, even the best stimulant draws only a weak response.
When the factories are healthy, the same stimulus yields more collagen, elastin and hyaluronic acid.
What the factory makes
Collagen types I & III
The main components of structure and elasticity
Elastin
The skin’s spring-back
Hyaluronic acid
The skin’s water reservoir
These three don’t need supplementing separately — with a healthy factory, they are made together.
How collagen is made matters as much as how much.
Collagen thrown together stiffly, and collagen woven smoothly like your original skin, can come from the very same injection.
A · Unsettled cell state
Collagen made in a rush, like scar tissue
Stiff, and it sits awkwardly in the tissue.
When stimulation lands on skin with a broken barrier, the cells respond in “emergency” mode. Collagen made this way can be coarse in texture, and the result can look unnatural. (Related pathway: TGF-β1)
B · Settled cell state
Collagen woven naturally, like your original skin
Soft — and the result lasts.
When the barrier is intact, the cells respond in “normal regeneration” mode. The collagen made here is the kind of regeneration we want. (Related pathway: TGF-β3)
✅ Obliv's treatment guide
That is why Obliv checks the state of your skin barrier before any treatment. Treat over a broken barrier, and the result turns out stiff and awkward.
Even “skin regeneration” splits into three approaches. Knowing which one fits you is the starting point.
Energy stimulation
Principle
Remodels existing collagen with heat, and switches on regeneration signals
Onset
1–3 months
Duration
6–18 months
Treatments
HIFU, RF, microwaves
Direct filling
Principle
Injects ready-made ingredients (such as HA) directly
Onset
Immediate
Duration
6–18 months
Treatments
HA fillers, collagen injections
Stimulation (reinforcement)
Principle
A dissolvable substance prompts your body to build new collagen
Onset
2–6 months
Duration
12–24 months
Treatments
Collagen-stimulating injections
✅ Obliv's treatment guide
We don’t crown one of the three as the answer. Obliv combines all three according to the state of your layers and your target timing.
The ratio of remodelling (energy) + new collagen (stimulation) + necessary volume correction (filling) differs from person to person.
A guide that answers the question: “is now the right time?”
20s · Prevention
At this stage the collagen loss doesn’t show in the mirror, but it has already begun. “Reinforcement” here isn’t about reversing visible change — it is about slowing the rate of decline itself.
Obliv's approach
Skin barrier care + gentle pacing with minimal-strength stimulation.
30s · Maintenance
This is when the skin’s volume, firmness and texture begin to change together. It may not stand out yet — but start now, and you bank the difference before the big changes arrive.
Obliv's approach
Collagen stimulation + whichever energy treatment is needed.
40s and over · Recovery
Once the decline has progressed, a single treatment may not be enough. What works is the combination: remodelling the collagen you have with energy, and building new collagen with stimulation.
Obliv's approach
A layer-by-layer diagnosis, then energy + stimulation + any volume correction needed.
Both are called “collagen injections” — but they work differently.
BIOSTIMULATOR · Stimulating type
An injection that makes your own body build collagen. Slower to show — but it lasts.
Biodegradable ingredients such as PCL and PLLA are injected into the lower dermis. Through a planned foreign-body response, fibroblasts are prompted to produce new collagen. The substance disappears over several months; the collagen it created stays.
SUPPLEMENT · Replenishing type
An injection that replenishes ready-made ingredients directly. Quick to work, but needs regular repeat sessions.
Skin-native ingredients such as HA (hyaluronic acid) are injected directly into the upper dermis and epidermis, quickly restoring moisture, elasticity and texture. Used alongside other treatments in the recovery and maintenance stages.
Energy treatments remodel the collagen you already have. Collagen-stimulating injections create new collagen.
Put the two together and existing collagen firms up while new collagen fills in. That is why Obliv designs energy + stimulation as a pair.
FAQ
Results start to appear 1–3 months after treatment and reach their peak at 3–6 months. Even after the injected substance has fully broken down in the body, the collagen your body built remains — lasting 12–24 months.
It depends on the quality of the collagen produced and your individual metabolism. In general it often lasts around 12–24 months. Results vary from person to person, and with the condition of your skin barrier, lifestyle and UV protection.
A collagen-stimulating injection places biodegradable ingredients (PCL · PLLA) that prompt your own body to build new collagen — slower to appear, longer-lasting. A collagen injection replenishes ready-made ingredients such as HA directly — quick to work, but needing regular top-ups.
Purpose matters more than age. For prevention, the approach suits the late 20s to early 30s; for maintenance, your 30s; for recovery, your 40s onwards — each stage is approached differently.
The two are synergistic. Energy treatments remodel the collagen you have; stimulating injections build new collagen. Combined, the results hold for longer.
Temporary swelling, bruising or a lumpy feeling can occur. These mostly settle within days to weeks, and precise control of injection depth and dose is the key to reducing nodules. Checking the skin barrier before treatment also helps minimise side effects.
