Dermapen 4, standalone vs. with PRP combination: how do they differ? Comparing choices for acne scars

Needle treatments like Dermapen 4 are reported to improve acne scar indentations even when used alone, but the degree of improvement varies from person to person[1]. When combined with PRP made from your own blood, some comparisons show better results than standalone treatment, though research findings across studies remain inconsistent[1][2]. When choosing, it is more efficient to compare based on "the purpose and number of sessions" rather than the name of the combination.

Can acne scars improve with Dermapen alone?

They often do improve. Fine needles create tiny holes in the skin, and the skin's natural healing response increases collagen production, which fills in the depressed scarring[3]. A key feature is that it avoids major surface abrasion of the skin.[4].

In studies examining acne scars, all showed visible improvement in appearance.[1]. However, the degree of improvement varies from study to study, and it cannot be said definitively that 'improvement will reach a certain percentage after a certain number of treatments.'[1].

What is different when combining PRP?

Additional benefits can be expected, but certainty is not yet sufficient. In a study comparing the left and right sides of the face in 64 people, after receiving three treatments at four-week intervals, the side with added PRP showed better improvement.[2].

However, this study did not determine in advance by lottery which side would receive which treatment, and the period for observing effects was short.[2]. In the study summary, results comparing monotherapy with PRP combination are inconsistent, and we are not yet at a stage where we can definitively say that combination therapy is superior.[4][1].

PRP also has other considerations. According to guidelines from the Japanese Society of Aesthetic Surgeons, the method of injecting PRP with added growth factors (bFGF) results in high incidence of scarring and raised areas, and is not recommended without careful consideration.[5]Ask about not just the name, but also the contents of what is being added.

Do pain and redness change depending on the combination?

Pain, redness, and swelling appear with Dermapen treatment regardless of which combination is used.[6]Research summaries showed that adding PRP may shorten the duration of redness.[6].

On the other hand, pain does not decrease even with PRP added, and in some cases it may increase when PRP is injected into the skin.[6]If you are sensitive to pain, it is reassuring to consult about the anesthesia method as well.

How does this compare to laser treatment?

Research conclusions are divided on which is superior.[1]Some studies showed that fractional laser had higher effectiveness, while others showed they were similar.[1].

In all studies that compared side effects, Dermapen had milder adverse effects.[1]There are reports that the percentage of people who completed treatment through to the end was higher with Dermapen.[1]The choice comes down to whether you prioritize stronger results or easier maintenance of treatment.

What kind of people should be cautious before treatment?

In all skin treatments that work by wounding and healing, there are conditions that warrant careful consideration.[7]People with a tendency toward raised scarring, those with rosacea or dermatitis causing rough skin, and those who have recently undergone other deep skin treatments.[7].

Based on the article alone, you cannot decide which combination suits your acne scars. During consultation, tell the doctor about the shape and depth of your acne scar indentations, whether acne is currently present, and any previous skin treatments you have received. Confirm what combination will be used, how many sessions, and the reasoning behind this plan.
