Which laser treatment for mild atrophic scars on penis skin?

Thank you for your question. Treating atrophic scars on penile skin requires a careful and conservative approach due to the sensitivity and vascularity of the area. For mild atrophic scars that are over 3 years old, the following laser treatments may be considered:

Fractional Non-Ablative Lasers (e.g., 1540 nm Erbium Glass):
These lasers are often preferred for sensitive areas like genital skin. They promote collagen remodeling without significant damage to the skin surface and typically require multiple sessions. Downtime is minimal, and the risk of pigmentation changes is lower than with more aggressive lasers.

Pulsed Dye Laser (PDL, 585–595 nm):
If the scar has residual redness or vascularity, PDL can help reduce discoloration and improve texture. It's gentle and has been used successfully on genital skin for vascular lesions as well.

Low-Density Fractional CO₂ or Er:YAG (Ablative):
These more aggressive options may be used cautiously in specialized settings. They remove micro-columns of tissue to stimulate healing and collagen production but come with higher risk and longer recovery. These are typically reserved for more severe or refractory scarring.

Important Considerations:

A test spot is often recommended first to assess skin response.

Laser treatments should only be performed by an experienced dermatologist or laser specialist familiar with treating genital skin.

Consistent post-treatment care and sun protection (even for non-sun-exposed areas) are essential to reduce the risk of post-inflammatory hyperpigmentation or irritation.

Because your scars are longstanding and mild, a non-ablative fractional laser would likely be the most appropriate and safest initial option.
