PDRN Therapy (Salmon DNA) in Connecticut: Greenwich MD offers physician-supervised PDRN therapy at its Stamford clinic, bringing one of regenerative medicine’s most promising skin-renewal treatments to patients across Connecticut. Full PDRN Therapy Program details

Medically reviewed by Susana Querido, MD, Triple Board-Certified in Family Medicine, Aesthetic Medicine, and Anti-Aging & Regenerative Medicine. Medical Director, Greenwich MD.
PDRN therapy, sometimes called salmon DNA therapy, is a regenerative injectable treatment that uses polydeoxyribonucleotide fragments to signal the body’s own repair pathways. At Greenwich MD, located at 1351 Washington Boulevard in Stamford, the program is built around one principle: every injection is performed by a licensed physician, not delegated to a mid-level provider. That matters because PDRN works at a cellular level, stimulating tissue regeneration and collagen synthesis, and the placement, depth, and dosing decisions require clinical judgment that only a physician can reliably provide. Patients travel from across Connecticut, including Greenwich, Darien, New Canaan, Westport, and Norwalk, to access this level of care, largely because physician-administered PDRN therapy is still uncommon in the state.
Before booking a consultation, it helps to know the basics of what PDRN therapy involves and how Greenwich MD structures its program.
PDRN therapy is still gaining recognition in the United States, and the clinical literature supporting it comes primarily from European and Asian research centers where physician-administered protocols have been the standard from the start. When a treatment’s evidence base is built on physician-led care, replicating those outcomes outside that framework is genuinely risky. Injection depth, dilution ratios, and treatment intervals all affect whether a patient gets the regenerative response described in published studies, or a suboptimal result. At Greenwich MD, Dr. Querido reviews each patient’s skin condition, medical history, and goals before writing a protocol, and she’s the one holding the syringe at every appointment. Patients interested in how PDRN fits into a broader plan for skin repair may also want to review the clinic’s Regenerative Medicine offerings for context on where this treatment sits within a comprehensive approach to tissue renewal.
Triple Board Certification: Dr. Susana Querido holds board certifications in Family Medicine, Aesthetic Medicine, and Anti-Aging and Regenerative Medicine. That combination isn’t typical among injectors in Connecticut. It means she approaches PDRN therapy not just as a cosmetic procedure but as a medically grounded regenerative treatment, one she can calibrate based on a patient’s overall health picture, not just their skin complaints. She’s familiar with the peer-reviewed literature on PDRN’s cellular mechanisms and applies that knowledge to every treatment plan she designs.
Continuity of Care: At many aesthetic clinics, a physician consults at the first appointment and hands off subsequent sessions to nursing staff. That’s not how Greenwich MD operates. Dr. Querido sees the same patients at every visit, which lets her track tissue response over time, adjust protocols when needed, and catch early signs of any reaction before they become problems. For a relatively new treatment like PDRN therapy, that continuity is worth prioritizing when choosing a Connecticut provider.
Integrative Approach: Dr. Querido considers PDRN therapy one tool in a larger regenerative toolkit. She’s comfortable discussing how PDRN compares to or complements other treatments, and she’ll tell patients directly if a different protocol would serve their goals better. That kind of straightforward clinical guidance is part of what brings patients from Greenwich, Darien, New Canaan, Westport, and Norwalk to a Stamford clinic rather than seeking care closer to home.
Greenwich MD structures its PDRN therapy offerings around three primary applications, each targeting a distinct set of skin concerns. During the initial consultation, Dr. Querido determines which approach fits a patient’s presentation and goals.
This is the most common application of PDRN therapy at Greenwich MD. Fine lines, textural irregularities, and a loss of skin luminosity all respond to PDRN’s ability to activate fibroblasts and increase local collagen synthesis. The treatment is delivered via microinjection across the face, with particular attention to zones where collagen loss tends to present first, including the periorbital area, cheeks, and mid-face. Patients with dull skin often notice brightness improvements within a few weeks of starting a series.
The neck and chest are areas where skin aging often accelerates because they’re exposed to UV but less frequently treated with restorative therapies. PDRN’s regenerative signaling makes it well suited to these zones, where the skin tends to be thinner and more reactive than facial tissue. Dr. Querido adapts injection technique and session spacing for these areas, since their anatomical characteristics differ from the face in ways that affect both treatment delivery and recovery.
PDRN therapy’s anti-inflammatory and tissue-repair properties make it a useful addition to post-procedure recovery plans, particularly after laser resurfacing, chemical peels, or other treatments that intentionally stress the skin barrier. When incorporated into a recovery protocol, PDRN can help accelerate healing, reduce redness duration, and support the quality of the new tissue being formed. Dr. Querido discusses this application with patients who are planning combination treatment timelines.
Understanding what happens at each stage of a PDRN therapy appointment helps patients arrive prepared and reduces anxiety about a treatment they may not have experienced before.
| Stage | What’s Included | Time |
|---|---|---|
| Initial consultation | Medical history review, skin assessment, personalized treatment plan, pricing discussion | 30 to 45 min |
| Skin preparation | Cleansing, topical numbing cream application if indicated | 10 to 20 min |
| PDRN injection session | Physician-administered microinjections across target zones | 20 to 30 min |
| Post-treatment review | Immediate skin check, aftercare instructions, scheduling of next session | 5 to 10 min |
| Follow-up visit | Progress assessment, protocol adjustment if needed, continuation of series | 30 to 45 min |
PDRN therapy suits a broad range of patients, but it’s not the right choice for everyone. Dr. Querido uses the consultation to confirm candidacy and flag any reasons to modify or delay treatment.
PDRN therapy may not be appropriate for patients with active skin infections, known hypersensitivity to salmon or fish-derived products, certain autoimmune conditions, or those who are pregnant or breastfeeding. Patients on specific anticoagulant medications will need to discuss timing with Dr. Querido before proceeding. Full contraindication screening happens at the consultation, so patients with questions about their eligibility are encouraged to book a visit rather than self-screening.

The table below outlines what to expect at each stage of your visit. Costs are confirmed during your consultation based on your individual treatment plan.
PDRN therapy is considered an elective aesthetic and regenerative treatment, so it isn’t covered by health insurance plans. Greenwich MD can walk you through payment options during your consultation. Some patients use health savings accounts (HSAs) or flexible spending accounts (FSAs) for aesthetic medical treatments, but it’s worth confirming eligibility with your plan administrator before your appointment.
Each in-office session takes roughly 30 to 45 minutes from skin preparation through the injection and post-treatment check. An initial series typically involves three to four sessions spaced one to two weeks apart, so the active phase of treatment runs about four to six weeks. Maintenance visits afterward are less frequent, usually one session every four to eight weeks depending on your skin’s response.
PDRN therapy has a well-documented safety profile in the clinical literature, with most research coming from European and Asian centers where it’s been used for years. Side effects at the injection site, such as mild redness or swelling, are common and typically resolve within 24 to 48 hours. Serious adverse events are rare when treatment is performed by a qualified physician following established protocols. At Greenwich MD, Dr. Querido screens every patient for contraindications before starting treatment, which is one reason physician oversight matters for this particular therapy.
Good candidates are generally adults experiencing early-to-moderate skin aging, chronic dullness, or textural irregularities who want a regenerative approach to skin improvement. People recovering from laser or chemical peel treatments sometimes use PDRN to support healing. Patients who don’t want volumizing injectables but still want an injectable treatment that works at a structural level are often good fits. Dr. Querido confirms candidacy at the consultation, since individual medical history affects eligibility.
Most patients describe the sensation as a series of small pinpricks across the treatment area. Topical numbing cream is applied before the injections for patients who prefer it, which reduces discomfort considerably. Post-treatment, the skin may feel slightly tight or tender, and some mild redness is normal for the first day or two. There’s no significant downtime, so most patients return to their regular activities the same day.
PDRN therapy works differently from most common aesthetic treatments. Unlike dermal fillers, it doesn’t add volume; it signals your body’s repair mechanisms to generate new tissue. Unlike neurotoxins, it doesn’t relax muscles; it addresses skin quality directly. It can complement those treatments rather than replace them. Compared to topical growth factor serums, the injected form delivers active compounds directly to the dermal layer, bypassing the absorption limitations of topical application. Dr. Querido can help you figure out where PDRN fits, or doesn’t fit, in your specific plan during a consultation.
PDRN products are available through online channels, but those options carry real risks: no quality-control verification, no medical screening, no injection expertise, and no clinical follow-up if something goes wrong. The outcomes reported in the research literature on PDRN therapy come from physician-administered protocols using pharmaceutical-grade products, and replicating those results at home isn’t realistic. At Greenwich MD, Dr. Querido uses verified pharmaceutical-grade PDRN, performs every injection personally, and monitors each patient’s response across the full course of treatment. For a therapy built on cellular-level repair, the quality of administration matters as much as the product itself.
