Acne scars, particularly atrophic (indented) scars, present a unique challenge because they represent a loss of collagen and tissue structure. For individuals exploring Microneedling With PRP Therapy in Riyadh, this combination treatment offers a scientifically supported way to remodel scar tissue and improve skin texture. Microneedling With PRP Therapy in Riyadh The process works by breaking down old, disorganised collagen and stimulating the production of new, organised collagen fibres.
How the Combination Remodels Scars
Microneedling: Breaking Down Old Collagen
Microneedling, also known as collagen induction therapy, uses ultra-fine needles to create controlled micro-injuries in the skin . This process triggers the body’s natural wound-healing cascade, breaking down old, disorganised collagen and stimulating the production of new collagen and elastin—the proteins responsible for firm, smooth skin. The micro-injuries also promote the formation of new blood vessels, improving nutrient delivery to the skin .
PRP: Supercharging the Healing Response
Platelet-rich plasma (PRP) is derived from a small sample of your own blood. After centrifugation, the PRP contains a high concentration of growth factors that signal cells to proliferate and produce new collagen . When applied to the skin during microneedling, the PRP penetrates deeply through the microchannels, delivering these growth factors directly to the dermis . This combination has been shown to enhance percutaneous collagen induction and accelerate tissue regeneration more effectively than microneedling alone .
Clinical Evidence for Scar Reduction
Superior Results Over Microneedling Alone
A 2025 clinical study of 65 patients with post-acne scars compared microneedling with PRP against microneedling with saline. The PRP group showed a 43% improvement in scar severity, compared to just 19% in the saline group. Patient satisfaction was also significantly higher—80% of PRP patients reported being very satisfied, versus 53% in the control group.
The split-face study further confirmed these findings, with the combination side showing a 55.29% reduction in quantitative scar scores, compared to 33.89% on the microneedling-only side. The combination group also demonstrated significantly higher rates of excellent response (37% vs 10%).
Reduction in Scar Depth
A 2026 study on atrophic acne scars confirmed that combining PRP with microneedling improved skin texture and reduced scar depth more effectively than microneedling alone. The combination was found to be superior for improving skin texture and reducing the depth of acne scars in both clinical and self-assessment scores.
Safety and Tolerance
Across all studies, the treatment demonstrated a favourable safety profile. Transient erythema (redness) and edema (swelling) were the most common side effects, typically resolving within 4–5 days. No cases of hyperpigmentation or severe complications were reported in the major studies.
What This Means for Your Scars
The combination works through a clear biological pathway. The micro-injuries break down old scar tissue, while the PRP delivers growth factors that stimulate fibroblasts to produce new, organised collagen. This results in smoother texture, reduced scar depth, and improved overall skin quality. The treatment is suitable for various skin types, including Fitzpatrick skin type IV, which was the most common in one study.

Frequently Asked Questions
How many sessions will I need for acne scars?
Most clinical protocols recommend 3 sessions, spaced 4 weeks apart, for optimal scar remodelling and visible improvement.
Is the treatment effective for old scars?
Yes, studies included scars ranging from 3 months to 70 years old, with patients reporting improvements in pliability, colour, and texture across all scar ages.
When will I see results?
Some improvement may be visible after the first session, but the most significant results develop over several months as new collagen remodels the scar tissue.
Is the treatment safe for all skin types?
Yes, microneedling with PRP is considered safe for all skin types and tones, with a low risk of side effects.
What are the possible side effects?
Common side effects include temporary redness and swelling that resolve within 4–5 days. No severe complications or hyperpigmentation were reported in the major studies.
