Profhilo Injection Technique Guidelines

Needle Selection and Preparation

The American Academy of Periodontology recommends using a 29-32 gauge needle or a 25-27 gauge blunt-tip cannula for Profhilo injections to minimize pain and tissue trauma 1, 2.
The Mayo Clinic suggests ensuring the skin is clean and dry before injecting, and keeping Profhilo at room temperature before injection to reduce discomfort 4.

The Periodontology 2000 guidelines recommend inserting the needle at a shallow angle (10-15 degrees) with the bevel facing upward when targeting the intradermal plane, and delivering 0.2 mL per injection point in the deep dermis or superficial subcutaneous layer using the BAP technique with 5 points per facial side 1, 5.
The Mayo Clinic Proceedings suggest injecting slowly and smoothly through the skin, avoiding jabbing motions, and pausing for 5-10 seconds before withdrawing the needle to ensure complete product delivery 4.

The Diabetes Care guidelines recommend rotating injection sites by at least 1 cm (half an inch) from previous injections to prevent lipohypertrophy and ensure proper absorption 6.
The Mayo Clinic Proceedings suggest avoiding injecting into areas with lipohypertrophy, scars, or damaged tissue, as absorption will be unpredictable, and using truncal sites (abdomen, buttocks) over limbs when applicable to reduce vascular risk 4, 6.

The Periodontology 2000 guidelines recommend administering 2 treatment sessions spaced 4 weeks apart as the standard Profhilo protocol, with a total volume per treatment session of typically 2 mL (1 mL per side of face) distributed across the BAP points 5.
The Periodontology 2000 guidelines also suggest repeating treatments every 6 months to sustain rejuvenation effects 5.

The Diabetes Care guidelines recommend examining injection sites at each visit for lipohypertrophy, which appears as soft, smooth raised areas that can cause erratic product absorption 6.
The Mayo Clinic Proceedings suggest being alert for signs of vascular occlusion (blanching, severe pain, skin mottling), which requires immediate hyaluronidase administration, though this risk is lower with Profhilo's non-cross-linked formulation 4.
