Yachroma-Med Laser Treatment of Pigmented and Non-Pigmented Skin Lesions

 

The main advantage of laser therapy compared to conventional methods for treating pigmented skin disorders is selective photothermolysis. Selective photothermolysis provides selective thermal necrosis of melanosomes without pronounced thermal deterioration of surrounding cells and collagen structures. Therefore, an excellent cosmetic result can be achieved with minimal risk of scar formation. The use of CVL radiation, which corresponds to the high absorption of melanin at 511 nm is efficient for the pigmented lesion's treatment. Each CVL pulse has a duration of 20 nanoseconds and a peak power of up to several kW, to provide the selective heating of pigmentation as an ideal laser. CVL is an optimal treatment choice for seborrheic keratosis in terms of the energy deposition depth and selectivity according to Klyuchareva S. V., Ponomarev I. V., Topchiy S. B., Pushkareva A. E., Andrusenko Yu. N.Treatment of seborrheic keratosis with a copper vapour laser. Vestnik Dermatologii i Venerologii. 2019;95(3):2533.

Facial congenital melanocytic nevus represents a rare condition with a prevalence of about 2%. As periorbital congenital melanocytic nevus appears as a hyperpigmented plaque close to the eye, it inevitably poses cosmetic problems. The dual-wavelength copper vapor laser radiation at a wavelength of 511 nm which is highly absorbed by melanin and radiation at 578 nm is mostly absorbed by hemoglobin, seems to be
the most appropriate for the safe removal of periorbital congenital melanocytic nevus.

 See the paper Ponomarev, I. V., Topchiy, S. B., Pushkareva, A. E., Klyuchareva, S. V., & Andrusenko, Y. N. (2021). Treatment of Congenital Melanocytic Nevi With a Dual-Wavelengths Copper Vapor Laser: A Case Series. Journal of Lasers in Medical Sciences, https://journals.sbmu.ac.ir/jlms/article/view/28867/26609

 Melanin absorbs the radiation with a wavelength of 511 nm, 10 times more than the radiation with 1064 nm wavelength. Hence, selective photodestruction of melanosome with copper vapor laser requires less light energy than the mid-infrared laser. The high absorption of 578 nm radiation by oxyhemoglobin and hemoglobin as well as high absorption of 511 nm radiation by melanin limits the penetration depth of the laser and protects the underlying eye structures from injuries.

Colour tattoos, which difficult for removing by alexandrite and ruby lasers, respond to treatment with the yellow and green wavelengths of a copper vapor laser.

Warts and HPV warts are also well treated. It is reasonable to use a copper vapor laser when other less expansive treatment methods such as cryotherapy, electrocautery, 2 laser provide poor results. 

Copper vapor laser can be useful in the treatment of facial epidermal nevi distributed along Blaschkos line without inflammatory signs. See the paper Ponomarev IV, Topchiy SB, Kluchareva SV, Shakina LD. Epidermal nevus in blaschkoid distribution treated with dual-wavelength copper vapor laser. Indian J Dermatol Venereol Leprol 2021;87:718-20.
