PDRN Neck Treatment: Rejuvenating the Most Neglected Area of the Face

PDRN neck treatment begins with cleansing and topical anesthetic application (the neck is more sensitive than the face, so adequate numbing is important). The practitioner then administers PDRN using one of several techniques:

**Microinjection technique**: Multiple small injections (0.02-0.05 mL each) are placed intradermally across the entire neck surface using a fine-gauge needle (30-32G) or cannula. The injections are spaced 1-1.5 cm apart in a grid pattern covering from the jawline to the clavicle. Total volume is typically 2-4 mL per session.

**Mesotherapy technique**: A mesotherapy gun or manual multi-needle device delivers multiple microinjections rapidly at a consistent depth (1-2 mm). This technique is efficient for covering the large surface area of the neck and ensures even distribution of PDRN.

**Microneedling technique**: A microneedling device (pen or roller, 0.5-1.0 mm depth) is used across the neck while PDRN solution is flooded onto the surface. The micro-channels created by the needles allow PDRN to penetrate directly into the dermis. This technique is less invasive than injection and may be preferred for patients who are needle-sensitive.

Post-treatment, the neck may show mild redness, pinpoint bleeding (with injection techniques), and slight swelling for 24-48 hours. A soothing PDRN serum or bland moisturizer is applied, and patients are advised to avoid direct sun exposure and apply SPF diligently. Standard protocol involves 4-6 sessions spaced 2-4 weeks apart, followed by maintenance sessions every 2-3 months.
