PRP — Platelet-Rich Plasma

PRP stands for Platelet-Rich Plasma, which is prepared from 10–20 ml of your own blood. Through centrifugation, the portion concentrated with platelets and growth factors is separated and then applied topically or injected into the skin immediately following microneedling, laser, or subcision treatments. Its primary role is to aid recovery; PRP alone does not fill atrophic scars when used as a standalone treatment. Because it is autologous, there is a low risk of allergic reactions.

What is PRP and How Does It Work?

Platelets contain growth factors that play a vital role in wound healing and tissue regeneration. When concentrated and introduced to an area with controlled micro-injuries (such as after microneedling, laser, or subcision), PRP is expected to help the skin recover faster and promote more favorable collagen remodeling. Individual responses vary depending on platelet quality, processing methods, and application techniques.

Its True Role in Acne Scar Treatment

PRP is an adjunctive step, not a primary standalone treatment: controlled micro-trauma (needles, lasers, subcision) is what triggers regeneration, while PRP supports the recovery phase. Studies show that combining PRP with microneedling or laser yields better clinical outcomes in certain patient groups compared to these modalities alone, but PRP cannot replace them. Having the right expectations prevents you from spending money on standalone PRP treatments for scar revision.

Beyond Acne Scars: Other Applications of PRP

PRP is also used to accelerate post-laser recovery, improve skin elasticity and hydration via mesotherapy/micro-injections (often referred to as facial PRP/PRF), and support hair loss management according to specific medical indications. Each indication has varying levels of clinical evidence; our doctors will clearly explain what PRP can achieve and what remains uncertain.

Safety Profile

Because it is derived from your own blood, PRP does not cause allergic reactions to the substance itself; the primary risks stem from procedural factors (aseptic technique during blood drawing, processing, and reinjection) and injection technique. The procedure must be performed by a physician in a medical facility with strict sterilization protocols.

The Approach at BonBoz

Our dermatologists determine whether to incorporate PRP based on your specific treatment goals and individual skin profile. Blood is drawn and processed using a sterile kit, then applied immediately following microneedling, laser, or subcision, or administered via micro-injections as indicated. PRP is never sold as a standalone treatment course at BonBoz.

When should you see a doctor?

  • Đang có rối loạn đông máu, bệnh lý về máu hoặc đang dùng thuốc chống đông.
  • Da vùng định làm đang nhiễm trùng.
  • Đang mang thai hoặc cho con bú.
  • Bạn kỳ vọng PRP thay thế được các phương pháp trị sẹo rỗ — PRP thường đóng vai trò hỗ trợ, không phải phương pháp chính.

How is it performed?

Draw 10–20 ml of venous blood into a specialized tube, then centrifuge for 10–15 minutes to separate the platelet-rich plasma (PRP). Following microneedling, laser treatment, or subcision, the doctor applies PRP onto the newly created micro-channels or performs intradermal micro-injections using a fine needle. The entire procedure takes 45–60 minutes.

Before the procedure

Eat a light meal and stay well-hydrated before blood collection. Avoid alcohol and non-steroidal anti-inflammatory drugs (NSAIDs) for 2–3 days prior, as directed, since these can affect platelet function. Please inform us of any blood disorders, active infections, or current use of anticoagulants.

After the procedure

Follow the post-care instructions of the accompanying procedure (microneedling/laser). For mesotherapy: mild pinpoint redness and slight swelling may persist for 1–2 days; avoid makeup for 24 hours; apply sun protection; and avoid saunas and steam rooms for 3 days.

Possible risks — your doctor explains them before treatment

  • Mild bruising and swelling at the injection site for 1–3 days
  • Risk of infection if blood collection, centrifugation/separation, or injection procedures are not strictly sterile
  • Variable and unpredictable responses depending on the individual
  • Additional cost with minimal marginal benefit in certain cases

Who should NOT have this?

  • Blood disorders, thrombocytopenia, or coagulation disorders
  • Active systemic or localized infections
  • Currently taking anticoagulants without prior physician consultation
  • Active malignancies currently undergoing treatment
  • Pregnant or breastfeeding (insufficient safety data — defer treatment)
  • Expecting standalone PRP to fill atrophic scars

Frequently asked questions

Can PRP fill pitted acne scars?

Not on its own. PRP supports recovery after microneedling, laser, or subcision—these procedures are what actually stimulate skin regeneration.

Is PRP safe?

Because it is autologous, there is no risk of an allergic reaction to the PRP itself. Risks lie in sterilization protocols and injection technique, so it must be performed at a medical facility by a physician.

How much blood is drawn?

Typically 10–20 ml, equivalent to a routine blood test.

Is the procedure painful?

The blood draw feels like a routine blood test. For microinjections, a topical numbing cream is applied, resulting in only a mild prickling sensation.

How many sessions are needed?

It follows the protocol of the primary procedure (typically 3–4 sessions spaced 4–6 weeks apart); standalone facial PRP usually requires 3 sessions spaced 4 weeks apart, followed by maintenance.

What is the difference between PRP and PRF?

PRF is prepared without anticoagulants, forming a fibrin matrix that releases growth factors more slowly. Both are supportive therapies; the physician will select the appropriate option based on your clinical goals.

Can PRP treat hair loss?

It is indicated as a supportive treatment for hair loss with a moderate level of evidence; an initial examination is required to determine the underlying cause of hair loss.

What medications should be taken or avoided before PRP?

Avoid nonsteroidal anti-inflammatory drugs (NSAIDs) for a few days beforehand as directed, as they can affect platelet function; do not discontinue any prescribed medications on your own.

When will results be visible?

Faster recovery is noticeable within the first week; visible improvements in skin texture and elasticity typically appear after 4–8 weeks and over several sessions.

Who performs the procedure at BonBoz?

Dermatologists directly prescribe and perform the procedure; blood collection and centrifugation follow the clinic’s sterile medical protocols.
