Which Works Better for Acne Scars: Exosomes or PRP?
August 6, 2026PDRN, or Polydeoxyribonucleotide, is a skin regeneration treatment derived from salmon DNA. It works by repairing damaged tissue at a cellular level rather than sitting on the surface and doing nothing useful. For dark circles, it targets root causes, which is why results hold better than most topical creams people spend months on. Most patients need 3 to 6 sessions to see a meaningful difference, though that number shifts depending on cause and severity. The skin under the eye is thin and complex. Doesn’t forgive guesswork.
According to Dr. Anju Methil, dermatologist in Andheri, “Dark circles aren’t one problem. Some are pigmentation, some are vascular, some are just volume loss making shadows. PDRN addresses the tissue itself. That’s what makes it different from a brightening cream that sits on top and does very little underneath.”
What Does PDRN Actually Do for Dark Circles?
PDRN doesn’t just brighten things up. It changes what’s actually happening underneath.
- Tissue Regeneration: PDRN activates A2A receptors in the skin, triggering a repair process that rebuilds damaged tissue under the eye. Years of sun exposure, poor sleep, and ageing take a real toll on this area specifically. PDRN tells the cells to start fixing what’s broken. Slow process, but the result sticks.
- Improving Skin Thickness: The skin under the eye is often so thin that blood vessels show right through it. That’s a big part of why dark circles look dark. PDRN stimulates collagen and elastin production which gradually builds that layer up. And when the skin gets thicker, the discolouration becomes a lot less visible.
- Reducing Pigmentation: For dark circles driven by melanin deposits, PDRN reduces the inflammation that keeps triggering pigmentation and encourages faster cell turnover. It doesn’t bleach anything. It corrects the activity causing the problem. Different approach, better outcome for the right patient.
- Improving Circulation: A bluish or purplish tint usually points to poor microcirculation. PDRN supports vascular repair at a micro level which helps address this. But not every dark circle is vascular. So assessment before treatment isn’t optional.

How Many Sessions Does It Actually Take?
Most patients fall into a clear framework, though the exact number depends on what’s driving the concern.
- The Typical Session Range: Mild dark circles with early pigmentation can shift in 3 sessions. Long-standing discolouration, volume loss, or vascular causes typically need closer to 6. Some maintenance after that, but the core work gets done in the initial course. Worth knowing before you start budgeting for it.
- Spacing Between Sessions: Sessions are spaced 2 to 4 weeks apart. That gap exists because PDRN triggers a biological repair process that needs time to complete before the next session builds on it. Rushing the schedule doesn’t speed anything up. It just interrupts what’s already working.
- What to Expect After Each Session: Some mild swelling or redness around the injection site for 24 to 48 hours. Nothing that stops daily activity. Most patients start noticing a real difference around sessions 3 or 4. Because the repair process keeps going between appointments, the skin continues improving even when you’re not in the clinic.
- Factors That Push the Session Count Higher: Chronic sun exposure, smoking, very thin under-eye skin, or dark circles that have been present for years all increase the sessions needed. Younger skin with more existing collagen tends to respond faster. So the timeline varies, but the treatment still works across the range.

Why Choose Dr. Anju Methil for PDRN Treatment?
Dr. Anju Methil has over 29 years of clinical experience in dermatology and cosmetic skin treatments. She holds an MBBS, DDV, and MD in Dermatology with active memberships in IADVL, IMA, and CDSI. Before recommending PDRN for dark circles, she assesses the actual cause, whether pigmentation, vascular, or structural, because the plan changes entirely depending on what’s driving it. Nothing gets assumed in the room.
Her approach is specific to what each patient presents with. Injection depth, session frequency, and whether PDRN is combined with another treatment are all decided after a proper under-eye evaluation. Treating the wrong cause, even with a good treatment, produces poor results. Patients leave with a clear picture of what PDRN can realistically do for their dark circles and an honest plan to get there. Call +91 8779911797 to book your consultation.
FAQs
Is PDRN treatment painful for dark circles? A numbing cream is applied beforehand. Most patients feel a mild pinch during injection, nothing significant after.
How soon will I see results from PDRN for dark circles? Most patients notice visible improvement around session 3 or 4, with continued progress between appointments.
Can PDRN be combined with other dark circle treatments? Yes. Depending on the cause, it can be paired with fillers or other treatments for a more complete result.
Is PDRN safe for the under-eye area? Yes, when done by a qualified dermatologist. The under-eye area needs precise technique and proper assessment first.
