What actually happens to the skin when we apply a biostimulator?
Instead of filling or altering volumes, the biostimulator acts as a "biological signal".
After being injected, it sends the message to the fibroblast that it's time to rebuild the skin's structure.
This process involves three internal phases:
-
Fibroblast recruitment
-
Production of collagen types I and III
-
Gradual compaction of the dermis
In other words, the result doesn't come from the product itself, but from the response. of its own fabric, which makes it natural, safe and elegant.
Is biostimulator suitable for all types of sagging skin?
No. This is a common question, and the answer requires care.
The biostimulator works best when there is mild to moderate sagging.
It does not replace:
• excess skin
• very low-lying structures
• cases where bone support is reduced (which may require the use of fillers)
Therefore, the analysis of biological age It's more relevant than your age on your ID card.
Patients aged 30, 40, and 60 will have completely different responses to the same product.

Before and After Collagen Biostimulators






Does biostimulator leave the face feeling heavy or puffy?
This is one of the most common concerns — and totally understandable.
But the answer is not.
Biostimulators do not create structural volume like fillers.
The slight swelling the following day is just a reaction to the injection and disappears quickly.
What remains is the improved firmnessNot the artificial augmentation of the face.
Why do some people respond more and others less?
Each person's skin has its own metabolic rate.
The answer depends on factors such as:
• current collagen quality
• genetics
• lifestyle
• biological age
• accumulated sun exposure
• nutrition and level of systemic inflammation
Therefore, two people who use the same dose of Sculptra may have different results.
It's not a product defect; it's a characteristic of the organism.

Although both are biostimulants, they have distinct behaviors:
sculptra
• more diffuse and global stimulus
• Excellent solution for sagging skin in large areas
• more gradual evolution
Radiesse
• more localized stimulus
• Immediate improvement in texture
• Excellent for jawline, chin, and neck
Choosing one or the other depends on the anatomical assessment, and often the best plan includes... smart combination.
Can biostimulators be used on the body?
Yes, and with excellent results.
The most commonly treated body areas include:
• arms
• abdomen
• inner thighs
• buttocks (for firmness and a lifting effect)
• knees
The body responds very well to the stimulus, especially in patients who have lost weight or who have experienced collagen loss due to age.
How long does the result last?
The average durability is 18 to 24 monthsdepending on:
• age
• metabolism
• lifestyle
