Which signs suggest infection after a skin procedure?
Healing redness fades day by day; redness that spreads, throbs, or weeps after improving points the other way.
Some redness, warmth, and swelling belong to normal healing after injections, lasers, and needling — the defining feature is that they peak early and then improve. Infection tends to break that direction of travel, with an area worsening again after days of getting better.
The pattern that breaks the healing curve
Signs worth acting on include redness that expands beyond the treated area, heat and throbbing pain that intensify, yellowish discharge or pus, and fever or feeling generally unwell. One sign alone can be ambiguous; several appearing together, or any worsening trend, strengthens the suspicion.
How skin responds to a procedure differs from person to person, which is exactly why self-diagnosis with leftover ointments or antibiotics is discouraged. The reliable route is an early consultation at the treating clinic, where the skin can be examined directly and treated appropriately if infection is confirmed.
