Biostimulators are currently receiving a lot of attention in the field of skin rejuvenation due to their different approach compared to familiar beauty methods. So what is a biostimulator, how does it work, and why is it increasingly highly regarded by professionals? The following content from HBIO Clinic will help you understand more.
What is a Biostimulator? Should you get injections?
A biostimulator is a modern cosmetic procedure that works by stimulating the body’s natural production of collagen and elastin from within, instead of providing immediate results like fillers. When injected into the deeper layers of the skin, biostimulators directly affect fibroblasts, promoting skin structure regeneration, thereby improving firmness, elasticity, and slowing down aging naturally.
So, should you get biostimulator injections? This method is particularly suitable for those who desire sustainable, non-invasive skin rejuvenation and prioritize a natural look. The effects aren’t immediate but gradually improve over time, helping to maintain healthy skin from the root. However, to ensure safety and the desired results, choosing a reputable facility and a qualified doctor is extremely important.

Who should get Biostimulator injections?
Biostimulator is a skin rejuvenation solution that works through self-stimulation, suitable for many individuals who want to improve their skin naturally and long-term. This method is especially suitable for those who want to improve skin quality from within without invasive procedures or changes to facial contours.
Those who should get Biostimulator injections include:
- Individuals who are beginning to show signs of aging such as sagging and loss of firmness.
- Skin lacking elasticity, thin, weak, and dull.
- Individuals with fine wrinkles and small lines on their face.
- Those with slight loss of facial volume due to natural aging.
- Individuals who desire long-lasting skin rejuvenation with effects that gradually increase over time.
- Clients who are hesitant about fillers and prioritize natural and safe beauty.
How is Biostimulator different from fillers and other rejuvenation methods?
Biostimulators and fillers are both popular non-invasive cosmetic procedures, but their mechanisms of action and effects are completely different. Understanding the differences between biostimulators, fillers, and other rejuvenation technologies will help you choose the right, safe solution that meets your specific skin improvement needs.
| Criteria | Fillers | Biostimulator |
| Ingredient | It primarily uses hyaluronic acid (HA) | Biopolymers, CaHA, PN… |
| Mechanism of action | Fills in tissue and provides instant hydration | Activate the skin regeneration process from within |
| Effective time | Approximately 6 to 18 months | It can last from 6 months to several years |
| Visible results | The results are immediately visible after the injection | Gradual, natural improvement over time |
| How to maintain | A booster shot is needed annually | The effect continues even as the sensation diminishes |
| Collagen stimulating ability | Does not promote collagen production | It has the potential to stimulate natural collagen production |
| Ability to handle when needed | It can be dissolved using hyaluronidase | Insoluble after injection |
Common Biostimulator Types in Aesthetics
Each type of biostimulator has different ingredients and mechanisms of action. The choice of product depends on your aging condition and treatment goals:
Sculptra (PLLA)
Sculptra’s main ingredient is Poly-L-Lactic Acid (PLLA). This is an early generation biostimulator and remains the number one choice for discreetly restoring facial volume.
- Mechanism: PLLA microparticles stimulate the production of Type 1 collagen. After injection, Sculptra gradually dissolves, but a new collagen network is formed to replace it.
- Advantages: Extremely effective for those with gaunt faces and widespread sagging skin.
- Results: Gradual improvement after 4-8 weeks, peaking after 6 months.

Radiesse (CaHA)
Radiesse contains Calcium Hydroxylapatite (CaHA) particles suspended in CMC gel. This is a unique “hybrid” product between a filler and a biostimulator.
- Mechanism: Immediately after injection, the CMC gel helps fill deep wrinkles instantly. Then, the CaHA particles create a solid framework for collagen and elastin to attach to and develop.
- Advantages: Excellent tissue lifting ability, suitable for creating sharp jawline contours or hand rejuvenation.
- Results: Immediate filling effect and long-lasting firmness.
Polynucleotide (PN)
While Sculptra and Radiesse focus on structure, Polynucleotide (PN), typified by lines like Rejuran, focuses on cell repair and healing.
- Mechanism: PN are DNA fragments extracted from salmon testes, with high compatibility with human DNA. They help repair damaged skin cells, strengthen the skin’s protective barrier, and stimulate fibroblasts.
- Advantages: Particularly effective in treating acne scars, brightening dark circles under the eyes, minimizing pores, and restoring sensitive/thin and weak skin.
- Results: Noticeably firmer, smoother, and healthier skin after the treatment.

Things to Remember When Getting Biostimulator Injections
Before choosing biostimulator injections, understanding these important considerations is crucial to ensuring safety and optimizing the effectiveness of skin rejuvenation. To avoid directly affecting collagen stimulation and long-term results, remember:
Thorough preparation before biostimulator injections
Before undergoing biostimulator injections, you need to be examined and consulted directly by a qualified doctor to accurately assess your skin condition, degree of aging, and improvement needs. Choosing the right type of biostimulator and dosage suitable for your body is very important.
In addition, you need to fully inform your medical history, allergies, and previous cosmetic procedures to minimize risks. Absolutely do not get injections if your skin is inflamed, infected, or your health is unstable.

Important Notes During and Immediately After Injection
During the injection process, biostimulator injections must be performed at a reputable facility, ensuring sterility and using genuine products. After the injection, the skin area may be slightly swollen or red; this is a normal reaction.
You should avoid touching, massaging vigorously, heavy makeup, saunas, or exposure to high heat in the first few days. Following your doctor’s aftercare instructions will help the active ingredient stimulate collagen production more effectively.
Proper Skin Care
After biostimulator injections, proper skin care will contribute to prolonging the rejuvenation results. You should maintain a healthy lifestyle, get enough sleep, and limit alcohol and stimulants.
Supplementing with foods rich in vitamins and minerals and drinking enough water will support collagen regeneration from within. At the same time, protect your skin thoroughly with sunscreen when going outside and attend regular follow-up appointments to monitor long-term results.
