Laser therapy can be an effective treatment for acne by targeting the root causes of breakouts and improving skin appearance.

• P. acnes(the bacteria responsible for acne) produces porphyrins, which absorb laser light.
• When lasers hit these porphyrins, they release oxygen radicals that destroy the bacteria, reducing inflammation and new breakouts.

• Lasers can target and shrink overactive sebaceous (oil) glands.
• Less oil production means fewer clogged pores and fewer breakouts.

• Intense pulsed light (IPL)reduce redness and swelling in active acne.
• They also help with post-inflammatory erythema (red marks left after acne heals).

• Fractional lasers (e.g. CO₂) stimulate collagen, helping to repair acne scars and improve skin texture.
• This can smooth out pitted or uneven skin caused by severe acne.

• Some lasers (like Nd:YAG) gently exfoliate the skin, helping to clear dead skin cells and prevent clogged pores.
