Instead of filling it in, it encourages my skin to produce collagen on its own.
It applies the "make it yourself" stimulus. It gives the stimulus: "Make it yourself".
Planned foreign body reaction
The principle of collagen-stimulating injections is simple.
If a slowly dissolving substance in the body (biodegradable ingredients such as PCL and PLLA) is injected into the skin,
the body recognises this substance as a "stimulus". Cells responding to the stimulus begin to produce collagen.
The injected substance eventually disappears, leaving only the collagen I produced.
STEP 01
Inject a substance that dissolves in the body into the skin
Biodegradable ingredients such as PCL and PLLA are injected to a specified depth.
STEP 02
The body recognises this as "stimulation".
A planned foreign-body reaction begins within a controlled range.
STEP 03
The cells that produce collagen are moving
Fibroblasts (the collagen factory in the skin) are activated.
STEP 04
The substance you put in disappears over the course of several months.
It is metabolised in the body without leaving any residue.
STEP 05
Only the collagen I made remains
Over several months, elasticity and density improve.
There are moments when, rather than feeling an urgency to fix something straight away, you feel like preparing slowly from now on.
Collagen Boost is an approach tailored to that feeling.
It feels burdensome to keep topping it up with filler

I think I should start doing something from now on.

Collagen begins to decrease in production around the age of 20.
Not only does the rate of ageing vary, but the rate at which it declines also differs depending on sunlight, hormones and inflammation.
-1% / year
Natural decrease
From age 20 onwards, it steadily decreases by about 1% each year.
-30% / year
The first 5 years after menopause
Hormonal changes accelerate the loss of skin collagen.
UV
UV degradation
Ultraviolet rays directly break down collagen in the skin.
Without UV protection, the effectiveness of any regenerative treatment is halved.
If your twenties are taken as 100, this is what it looks like when showing the amount remaining every 10 years.

Decreases to less than half in your 60s
The reason the results differ even when the same injection is used is simple. No matter how good the stimulus from the injection is,
if the skin cells receiving it are tired, collagen is not produced well.
More important than the performance of the injection is the condition of my cells first.
There are thousands of "collagen factories" in 1 cm² of skin. If these factories are exhausted, even the best stimulant will trigger only a weak response.
Conversely, if the factories are healthy, more collagen, elastin and hyaluronic acid are produced even with the same stimulus.
Things the factory makes
Collagen types I and III
Key ingredients for structure and elasticity
Elastin
the skin’s ability to bounce back
Hyaluronic acid
The skin's moisture reservoir
These three are not things that need to be supplemented separately; if there is a healthy factory, they are made together.
Just as important as how much collagen is made is how it is made.
Collagen that is produced stiffly and awkwardly, and collagen that is woven smoothly like natural skin, can differ even with the same injection.
A · Unstable cell state
Rushed collagen, like scar tissue
It is stiff and blends awkwardly with the fabric.
When the skin barrier is compromised and irritation is applied, cells respond in 'emergency' mode. The collagen produced at this time can have a rough texture, and the results may look unnatural. (Related pathway: TGF-β1)
B · Stable cell state
Collagen naturally woven like your original skin
Gentle, and the results last a long time.
When the barrier is intact and stimulated, the cells respond in "normal regeneration" mode. The collagen produced at this point is the kind of regeneration we want. (Related pathway: TGF-β3)
✅ Obliv's treatment guide
That’s why Obliv checks the condition of your skin barrier before any treatment. If a treatment is performed while the barrier is compromised, the results can look stiff and unnatural.
Even for the same "skin regeneration", there are three different approaches. Knowing which one is right for you is the starting point.
Energy boost
principle
Reshape existing collagen with heat, and switch on regeneration signals
Onset of effect
1–3 months
continuation
6–18 months
this procedure
HIFU, RF, microwave
Enter directly
principle
Inject pre-made ingredients (HA, etc.) directly
Onset of effect
Immediately
continuation
6–18 months
this procedure
HA fillers, collagen injections
Stimulation (reinforcement)
principle
The dissolving material encourages my body to produce new collagen
Onset of effect
2 to 6 months
continuation
12–24 months
this procedure
Collagen stimulation injection
✅ Obliv's treatment guide
We do not make one of the three the answer. Obliv combines three elements depending on the patient’s tissue condition and target timing.
The ratio of remodelling (energy) + new collagen (stimulation) + necessary volume correction (filling) varies from person to person.
This is a guide that answers the question, "Is now the right time?"
20s · Prevention
The collagen loss at this stage is not visible in the mirror, but it has already begun. The "reinforcement" at this point is not about reversing visible changes, but about slowing the rate of decline itself.
Obliv's approach
Skin barrier care + controlled pacing with minimal irritation.
30s · Maintained
This is the point at which the skin’s volume, firmness and texture begin to change together. It may not yet be very noticeable, but if you start now, you can build up a difference before major changes appear.
Obliv's approach
Collagen stimulation + combined with the necessary energy-based treatment.
Over 40s · Recovery
When the condition has progressed, a single procedure may not be enough. A combination that remodels existing collagen with energy and stimulates new collagen production is effective.
Obliv's approach
A design based on a layer-by-layer diagnosis: energy + stimulation + the necessary volume correction.
Although both procedures are called "collagen injections", they work differently.
BIOSTIMULATOR · Stimulatory type
An injection that prompts your body to produce collagen. The effects take a while to appear, but they last a long time.
Inject biodegradable ingredients such as PCL·PLLA into the lower dermis. Through a controlled foreign body reaction, fibroblasts are induced to produce new collagen. The injected material disappears over several months, and the collagen that is produced remains.
SUPPLEMENT · Supplementary
An injection that directly replenishes pre-formed ingredients. It works quickly, but periodic repeat treatments are needed.
Directly inject skin-derived ingredients such as HA (hyaluronic acid) into the upper dermis and epidermis. Quickly improves moisture, elasticity and skin texture. Used alongside other treatments during the recovery and maintenance stages.
Energy treatments remodel existing collagen. Collagen-stimulating injections create new collagen.
When the two approaches are combined, the existing collagen becomes firmer while new collagen is added. This is why Oblive designs a combined energy + stimulation approach.
FAQ
Yes, it is possible. Because collagen decreases by 1% each year after the age of 20, starting preventatively in your 20s, even if you don’t have sagging or wrinkles, is effective for maintaining a high baseline level.
It depends on the quality of the collagen produced and your individual metabolism. In general, it often lasts around 12 to 24 months. Results vary from person to person, and can differ depending on the condition of the skin barrier, lifestyle habits and UV protection.
The effects begin to appear 1 to 3 months after the procedure and reach their peak at 3 to 6 months. Even after the injected substance has completely broken down in the body, the collagen your body has produced remains, lasting 12 to 24 months.
The benchmark is purpose, not age. If the aim is prevention, the approach differs for people in their late 20s to early 30s; for maintenance, in your 30s; and for recovery, from your 40s onwards.
There is a synergy when used together. Energy-based treatments remodel existing collagen, and stimulating injections create new collagen. When these two approaches are combined, the results last longer.
Temporary swelling, bruising, and a lumpy feeling may occur. In most cases, these ease within a few days to a few weeks, and carefully controlling the injection depth and amount is key to reducing nodules. Checking the condition of the skin barrier before the procedure helps minimise side effects.
