Fraxel Dual 1927nm
Thulium fiber laser for non-ablative superficial resurfacing
이 치료에 대해
Fraxel Dual 1927nm is the latest thulium fiber laser specifically effective for melasma, age spots, and superficial fine lines. Non-ablative resurfacing minimizes tissue damage while precisely targeting epidermis and superficial dermis.
작용 기전
1927nm wavelength is at melanin absorption peak, selectively absorbed by melanin granules within melanocytes. Microzone thermal effects (MTZ) minimize surrounding tissue heat while efficiently removing pigment. Promotes epidermal regeneration and collagen neogenesis.
적응증
기대 효과
Melanin clearance becomes apparent within 2-4 weeks of initial treatment with pigmentation improvement evident. Maximum results achieved after multiple sessions (3-5 treatments). Minimal downtime is a key advantage.
임상 근거
위험 및 부작용
Post-treatment erythema and mild swelling occur during downtime. Rare post-inflammatory hyperpigmentation (PIH) may develop. Strict sun protection is essential.
