After undergoing any cosmetic treatment—dermal filler injection—it is essential to track carefully how your skin or affected area responds in the days that follow. While aesthetic protocols are low-risk and serious issues rarely occur, infections can still develop, and early detection is key to mitigating long-term consequences.

One of the earliest and most telling signs of infection is worsening rash that extends past the procedure perimeter. Normal post-treatment blush is typical right after the procedure, مرجع معرفی بهترین پزشکان but if it grows darker, invades adjacent tissue, or persists for more than a couple days, this could indicate an infection. Along with redness, be alert to excessive heat in the area. Healthy skin may feel slightly tender immediately after treatment, but if the area continues to feel hot for beyond 72 hours, it may be a urgent concern.

Pain is another key indicator. It is expected to experience temporary irritation after a cosmetic procedure, but if the pain spikes suddenly, as it worsens, it could signal an infection. Swelling that persists and expands is also a warning sign. Normal swelling usually reaches its height in 24 hours and then gradually improves.

Look for any exudate from the injection area. Serous fluid may be acceptable in the initial recovery phase, but foul-smelling exudate—which is thick yellow and unpleasant—is a strong sign of infection. You may also notice scabbing that looks unusual and is associated with an unpleasant odor.

Fever or chills are atypical after non-invasive treatments, and if they occur, they should not be ignored. A subfebrile reading may be an indication that your body is reacting to an infection that has taken root in the procedure zone.

Other signs include the onset of new bumps, fluid-filled sacs, or pus-filled lesions that were not noted right after the procedure. If the skin begins to ulcerate or you notice darkening that spreads, this could indicate a medical emergency that needs urgent attention.

If you experience any of these indicators, do not wait to see if they resolve on their own. Call your aesthetic specialist without delay. Infections after cosmetic treatments can escalate quickly, and timely therapy with antibiotics can protect your aesthetic results.

Always adhere strictly to your specialist’s guidelines precisely. Keep the area clean and refrain from handling it with contaminated skin. Avoid applying over-the-counter creams unless they are clinically sanctioned by your provider. Staying informed in the days after your treatment is the most effective strategy to preserve your aesthetic outcome.
