The Q-switched Nd:YAG laser can penetrate deeply into the skin layers, allowing for effective targeting of both superficial and deep pigment lesions. Its ability to reach deeper layers makes it particularly valuable for lesions that are resistant to other forms of treatment.

  • The Fractional CO2 laser is another modality that offers significant depth penetration and promotes skin collagen remodeling. This laser not only targets pigmentation but also induces a controlled injury to dermal layers, stimulating a healing response that improves skin texture and overall complexion. This combined mechanism of action—targeting melanin while enhancing skin surface quality—offers a multi-faceted approach to the treatment of Becker’s nevus.

  • 3-3. Collagen Remodeling and Skin Texture Improvement

  • Apart from targeting pigmentation, laser treatments like the Fractional CO2 laser also play a pivotal role in collagen remodeling. The laser induces a controlled thermal injury to the dermal tissue, stimulating the body’s natural wound healing processes. This results in an increase in collagen production, leading to improved skin elasticity and texture over time.

  • Clinical observations suggest that after undergoing such laser treatments, patients experience not only a reduction in hyperpigmentation but also enhanced skin smoothness and a reduction in textural irregularities. The collaborative action of reducing pigment while simultaneously promoting collagen regeneration positions these laser therapies as comprehensive solutions for patients seeking aesthetic improvement in conditions like Becker’s nevus.

4. Clinical Benefits
