A dermatologist I work with tracked 10,000 microneedling treatments over 4 years. The serious complication rate was 0.02 percent. That is 2 serious issues per 10,000 treatments. Most problems are mild and resolve on their own. But knowing what can happen helps you avoid it.
The most common side effects are redness swelling and mild tenderness. These affect 100 percent of patients to some degree. Redness typically resolves within 24 to 48 hours. Swelling within 12 to 24 hours. Tenderness within a few hours. Cold compresses help.
Bleeding and bruising occur in about 5 to 10 percent of treatments. This is more common with deeper needle depths above 1.5 millimeters. Applying gentle pressure stops minor bleeding. Bruising resolves in 3 to 7 days.
Infection is rare when proper protocols are followed. The risk is near zero with sterile single use cartridges. Never reuse cartridges. tbphp ships each cartridge individually sealed and EO sterilized. We have never had a confirmed infection associated with our cartridges.
Hyperpigmentation affects 3 to 7 percent of patients with darker skin types. The risk increases with deeper treatments and sun exposure after the procedure. Using the correct needle depth and strict sun protection reduces this risk significantly.
Allergic reactions to numbing cream occur in about 1 percent of patients. Always ask about lidocaine allergy before applying topical anesthetic. Patch testing is recommended for first time patients.
Scarring is extremely rare with microneedling because the epidermis is not removed. The micro channels heal quickly without scar tissue. The reported rate is less than 0.01 percent.
