GFC Tubes 10 ml: Sterile Autologous Growth Factor Concentrate Tubes for Hair Restoration, Skin Rejuvenation & Aesthetic Regenerative Medicine

GFC Tubes (10 ml) are sterile, single-use blood collection tubes for preparing Growth Factor Concentrate (GFC), an autologous platelet-derived preparation used in aesthetic medicine, dermatology and hair restoration. GFC therapy and PRP therapy are both autologous treatments derived from the patient’s own blood and used to treat hair loss, among other conditions. The tube is the first step: it collects the patient’s blood and starts the process that releases growth factors, so the concentrate can be prepared in the clinic in a short, repeatable workflow. 

GFC vs PRP: Understanding the Difference

Many clinics already offer platelet-rich plasma (PRP). The two preparations differ mainly in what is injected. PRP is a concentrate of platelets and plasma. GFC is the growth factor-rich fraction released after the platelets have been activated. PRP tubes typically contain an anticoagulant such as citrate to prevent clotting, whereas with GFC the platelets are intentionally activated inside the tube. The result is a solution that concentrates the signalling proteins platelets normally release at an injury site, without the cell layer that PRP contains. 

A published method study found that growth factor yields differ significantly between preparation protocols, and that commercial kits claiming to maximise yield can give unpredictable levels of bioactive factors from each blood sample. For that reason clinics should follow the protocol recommended for their specific tube, centrifuge and activator system, and keep to it for consistent results.

How the Growth Factors Work

Platelets store growth factors in their alpha granules and release them when activated. The key factors in platelet concentrates include bFGF, VEGF, IGF-1, TGF-β1 and PDGF-BB, and these are central to wound healing and tissue regeneration. In skin and scalp treatments they are thought to act on several fronts at once: 

• stimulating dermal fibroblasts and collagen production,
• encouraging new capillary growth around hair follicles and in skin,
• supporting follicle cells in the growth phase of the hair cycle, and
• helping regulate local inflammation during tissue repair.

Clinical Applications in Hair Restoration

Hair loss is the most common indication for GFC. Clinical use has been associated with reduced shedding and increased hair density and thickness over time, particularly in androgenetic alopecia. The growth factors are injected into the scalp, particularly into thinning areas, to stimulate dormant follicles and improve scalp health. GFC is often used on its own for early to moderate thinning, or alongside topical minoxidil, oral therapy or hair transplant surgery to support recovery and graft survival. 

Skin Rejuvenation & Aesthetic Dermatology

In aesthetic practice, autologous platelet concentrates are used for acne scarring, skin rejuvenation, melasma, vitiligo, stretch marks, peri-orbital and peri-oral rejuvenation, hair regeneration and volumising effects. GFC is commonly given as microneedling-assisted application or intradermal micro-injections to the face, neck, hands and décolletage. Because the preparation comes from the patient’s own blood, there is little risk of allergic reaction or transmitted infection, which many patients value. 

Dental, Orthopaedic & Wider Regenerative Uses

Autologous platelet concentrates are well established in dentistry. PRP, PRF and CGF are widely used in oral implantology, sinus floor elevation, socket preservation and periodontal and bone regeneration. Growth factor preparations are also used in some orthopaedic and sports medicine practices for joint and soft tissue indications. Practitioners should choose the preparation (PRF, PRP or GFC) that matches their clinical goal and the evidence for it. 

Preparation Workflow

1. Prepare the patient and draw venous blood with a sterile technique. The drawn volume is usually shared across several tubes.
2. Fill each 10 ml GFC tube to the indicated level, then invert gently as the manufacturer’s instructions direct.
3. Allow the tube to stand for the recommended activation period. A common protocol allows around 30 minutes of standing time in the tube. 
4. Centrifuge according to the validated protocol for your tube and centrifuge.
5. Draw off the growth factor-rich fraction from the top layer with a sterile syringe, then apply it by injection or microneedling as clinically indicated.

Always follow the manufacturer’s instructions for use, including the centrifuge speed, time and activation period.

Safety, Evidence & Responsible Use

Because GFC is autologous, its safety profile in clinical use is considered favourable. Even so, it should be performed only by qualified, trained clinicians in a clinical setting, using sterile single-use consumables and standard infection control precautions. The evidence also needs honest framing. GFC is a relatively new therapy, and early evidence in hair loss is promising but comes from small studies. Clinics should set realistic expectations, discuss that multiple sessions are usually needed and that results vary between patients, and avoid promising guaranteed outcomes. Use may be unsuitable for patients with certain blood disorders, active infection at the treatment site, or those on anticoagulant therapy, so screening is advised. 

Storage & Handling

• Store unopened tubes in the original sealed pouch, in a cool, dry place away from direct sunlight, and follow the storage conditions given on the pack.
• Check the expiry date on the pouch before use, and do not use if the pouch is damaged or the tube seal is compromised.
• Single-use only. Dispose of used tubes as clinical sharps and biohazardous waste.
• Label every tube with the patient’s name and details before drawing blood.
