Which post-treatment care steps help reduce the risk of pigment changes and infection after laser hair removal?

• A. Cool compresses
• B. Sun exposure
• C. Rubbing with a rough towel
• D. Hot baths

Answer: (A)

Cooling after laser hair removal helps calm the skin and limit inflammation, which in turn lowers the risk of pigment changes and infection. A cool compress reduces heat buildup in the treated area, preserves the skin barrier, and minimizes swelling and redness that can lead to pigment disruption. It also helps prevent crusting and tenderness that could invite infection.

Sun exposure should be avoided because UV light can trigger or worsen pigment changes and damage healing skin. Rubbing with a rough towel irritates and can disrupt the healing surface, increasing infection risk. Hot baths add heat and moisture that can worsen inflammation and delay healing. Cooling directly addresses the main risk factors, making it the most effective post-treatment step.
