PRP stands for Platelet Rich Plasma. PRP for acne scars makes use of a person’s own blood. The medical team then uses a centrifuge to spin the blood that has been collected in a vial at high speeds. This causes the blood to separate into layers, one of which is rich in blood cells called platelets. This layer also contains many growth factors, proteins, and other chemicals that promote tissue repair, regeneration, and healing.
PRP For Acne Scars Method:
The process of PRP acne scar treatment follow these basic steps:
- withdrawal of blood from a vein (usually around the elbow area)
- spinning of the blood vial to create the PRP product
- addition of an activating agent to the PRP product
- injection of the PRP under the skin in the acne-scarred areas
Cost:
The cost for PRP for acne scars treatments can range from $500 to $3000 or more. The total cost will depend on several factors including:
- number of treatment sessions
- extent of scarring
- need for other treatments (micro needling, laser, etc) to optimize results
- experience and popularity of your chosen practitioner
- travel costs
How PRP For Acne Scars Works:
PRP is rich in platelets, growth factors, proteins, and other biologic agents that promote healing. Old scar tissue is broken down and new collagen begins to form. New collagen gives the skin a rejuvenated look and blends acne scars into surrounding skin. This makes acne scarring much less conspicuous and less noticeable.
Results:
PRP for acne scars is a promising modality for the treatment of atrophic acne scars. It can work on its own, but most research suggests that combining it with other treatments such as micro needling, laser, or fat grafting will provide optimal results. It generally takes several months before results start to show.
PRP For Acne Number Of Sessions
Usually, around three sessions are recommended, spaced about 3 months apart. Some people will need significantly more sessions. A treatment plan including the total number of sessions needed, the time between sessions, and the use of other acne scar treatments will vary depending on several factors:
- type(s) of atrophic acne scars you have (icepick, rolling, boxcar)
- extent of the scarring
- extent of response to initial sessions
PRP For Acne After Care:
PRP is a low-maintenance procedure with essentially no downtime or recovery. You can return to work and activities right away. A cold compress can be useful to decrease initial redness and swelling. Avoiding direct sun exposure for several days is recommended.
Who Should Not Get PRP:
Some people are not good candidates for PRP. Having defective platelet cells because of disease or medications like blood thinners excludes an individual from being a good candidate. In general, you shouldn’t get PRP for acne scars if you’re someone that:
- has very low platelet counts
- has bleeding disorders
- is on blood thinners (warfarin/coumadin, Xarelto, etc)
- has an ongoing infection
- has chronic liver diease
Complications Of PRP For Acne Scars:
PRP is generally considered a very safe, non-invasive, and low-risk procedure. This is because it is a natural product that comes from your own body. As such, there is no risk of rejection or allergy. Potential side effects and complications of PRP for acne scars include:
- bruising
- swelling
- redness
- nerve injury (numbness or loss of movements that will usually be temporary)
- infection
Conclusion:
PRP for acne scars is a relatively non-invasive and safe technique. It uses your own blood products so carries no risk of rejection or allergy. Multiple sessions are required and it takes time for results to show maximally. PRP generally works best when combined with other modalities like micro needling or laser.
