Biostimulators, or Collagen Stimulating Injectables, are a category of injectable treatments designed to stimulate tissue responses and the production of skin components, particularly collagen. They may help address age-related changes in skin elasticity, firmness, and overall skin quality.
Biostimulators differ from conventional fillers, which primarily focus on restoring volume or enhancing facial contours. The effects of biostimulators generally develop gradually as tissues respond to treatment.
At Dr. Gorn Aesthetique, physicians assess skin quality, skin laxity, volume loss, facial anatomy, and tissue characteristics before selecting the appropriate product, injection sites, and techniques for each individual.
What Is a Biostimulator?
Biostimulator is a term used for certain injectable products that stimulate biological tissue responses and collagen production.
Products in this category may contain different substances, such as:
- Poly-L-Lactic Acid (PLLA)
- Calcium Hydroxylapatite (CaHA)
- Other substances or products with tissue biostimulation properties according to their indications
Each product has different ingredients, mechanisms of action, response timelines, and injection techniques. Therefore, the same treatment approach should not be applied to every type of biostimulator.
What Can Biostimulators Help Improve?
Depending on the product and tissue condition, biostimulators may be considered for concerns such as:
- Age-related changes in skin quality
- Reduced skin elasticity
- Thin-looking skin or reduced tissue firmness
- Certain degrees of skin laxity
- Facial aging associated with tissue changes
- Overall skin texture and skin quality
- Volume changes in selected cases, depending on the product
Treatment goals should therefore be determined according to the specific properties of the product being used.
How Do Biostimulators Stimulate Collagen Production?
As we age, the amount and structure of collagen in the skin may change, affecting tissue strength, elasticity, and overall skin quality.
Certain biostimulators are designed to trigger tissue responses at the treatment site, promoting processes associated with new collagen formation according to the product's mechanism of action.
Therefore, treatment outcomes are not solely the result of immediate filling. They also involve the body's biological response, which gradually develops after treatment.
How Are Biostimulators Different from Fillers?
Although both are injectable treatments, their primary purposes differ.
Fillers are commonly used to restore volume, fill depressions, or enhance contours in areas such as the chin, lips, or midface.
Biostimulators, on the other hand, focus on stimulating tissue responses and collagen remodeling, with changes generally developing over time.
However, certain products may provide both volumizing and biostimulatory effects. The distinction should therefore be based on the actual product rather than its category name alone.
How Are Biostimulators Different from Skin Boosters?
Skin Boosters generally focus on hydration, skin texture, and skin quality, particularly injectable products containing hyaluronic acid that are administered into the skin.
Biostimulators primarily aim to stimulate collagen production and subsequent tissue remodeling.
However, these terms may be used differently depending on the product and marketing context. It is therefore important to evaluate the product's active ingredients, mechanism of action, and approved indications.
Where Can Biostimulators Be Injected?
Suitable treatment areas depend on the specific product and its indications. These may include:
- Face
- Cheeks and Midface
- Lower Face
- Jawline in selected treatment plans
- Neck
- Décolletage
- Back of the Hands
- Other areas according to the product's specific indications
Not every biostimulator is suitable for every treatment area or injection technique, particularly in regions with complex anatomy or significant movement.
Can Biostimulators Lift and Tighten the Face?
Biostimulators may help improve tissue quality and firmness in selected patients with certain degrees of skin laxity. However, their effects should not be considered equivalent to a surgical facelift.
When the main concern is significant tissue laxity or displacement, collagen stimulating injections may not reposition tissues in the same way as surgery.
It is therefore important to determine whether the primary concern is skin quality, volume loss, or tissue laxity.
Can Biostimulators Reduce Wrinkles?
Wrinkles can develop for several reasons.
When wrinkles are associated with changes in skin quality and collagen, improving skin quality may help reduce the appearance of certain types of wrinkles.
However, wrinkles caused by muscle activity, such as frown lines or forehead lines, may require assessment for botulinum toxin treatment. Depressions associated with volume loss may require volume restoring treatments.
When Will Biostimulator Results Become Noticeable?
Biostimulator results generally develop gradually over time because they involve biological tissue responses and remodeling.
The time needed to observe changes and the appropriate period for evaluating results depend on the product, injection technique, dosage, and individual tissue response.
Therefore, the same results timeline should not be applied to every type of biostimulator.
How Many Biostimulator Sessions Are Needed?
There is no standard number of sessions suitable for everyone.
The treatment plan depends on:
- Type of product
- Dosage or amount used
- Age and skin quality
- Degree of skin laxity
- Treatment area
- Treatment goals
- Individual tissue response
Some products require protocols involving multiple sessions, while others follow different treatment schedules. Decisions should be based on the specific product and medical assessment.
Who May Be Suitable for Biostimulators?
Individuals may consider an assessment if they have concerns such as:
- Age-related changes in skin quality
- Loss of skin elasticity
- Thin-looking skin or reduced firmness
- Certain degrees of skin laxity
- A desire to support collagen production and skin quality
- A preference for gradually developing results
- Interest in a comprehensive facial rejuvenation plan
Are There Risks Associated with Biostimulators?
Yes. As injectable treatments, biostimulators may cause side effects such as swelling, redness, bruising, pain, or tenderness at the injection site.
Certain products may also carry a risk of developing nodules or lumps beneath the skin, along with other complications depending on the product, injection technique, and treatment area.
As with other facial injectable procedures, the anatomy of blood vessels and surrounding critical structures must be carefully considered. Treatment should be performed by a qualified physician using products appropriate for the intended injection site.
How Should You Care for Your Skin After Biostimulator Injections?
Aftercare instructions vary depending on the specific product. The same recommendations should not be applied to all types of biostimulators.
Some products have specific post-treatment massage instructions, while others do not.
Patients should therefore follow the post-treatment instructions provided for the specific product and by their treating physician. Do not massage the injection area unless specifically instructed to do so.
