Fractional carbon dioxide laser versus carbon‐assisted Q‐switched Nd: YAG laser in the treatment of dilated facial pores

Abstract

The term dilated facial pores refers to the visible openings on the surface of the skin that correspond to the dilated openings of pilosebaceous follicles. Large facial pores represent a common aesthetic complaint in both men and women with negative psychological impact. 1 They have been discussed in literature as sequelae of chronological aging and photoaging due to the defect in the collagen and elastin dermal framework. However, an increasing number of young patients are presenting at dermatology clinics with the complaint of dilated pores without signs of skin aging. 2 Other potential causative factors include sex, ethnic, and genetic predisposition, follicular size, and seborrhea. The association between increased sebum output and wide pores has been well established, and acne patients often complain of wide facial pores. 3 The treatment of dilated pores is difficult due to the multifactorial nature of its pathogenesis, and most current treatment options intend to address the associated factors. 4 A variety of treatment modalities have been tried, for example, topical and oral retinoids, chemical peels, microbotox, and energy-based devices. 4,5 The treatment

“…Therefore, the fractional CO2 laser showed a higher clearance rate, needed less number of sessions, and had a long‐lasting effect, especially for elderlies. On the other hand, the use of Q‐switched Nd:YAG resulted in less downtime and a greater reduction in sebum secretion, predominantly in younger patients 21 …”

“…Clinical observation showed the CO2 fractional laser (ablative laser) to be more effective than the Q‐switched ND:YAG laser (nonablative laser). Multiple sessions are needed to achieve further improvements 14–21 . Nonablative and unipolar radiofrequency devices reduce sebum production and increase dermal collagen bundles, improving large facial pores.…”

“…Multiple sessions are needed to achieve further improvements. [14][15][16][17][18][19][20][21] Nonablative and unipolar radiofrequency devices reduce sebum production and increase dermal collagen bundles, improving large facial pores. These devices are safe and have minimal side effects.…”

Comparison of efficacy and safety of tretinoin 0.05% and glycolic acid peeling 70% in axillary and neck lesions of acanthosis nigricans: A single‐blinded, randomized trial

“…Additionally, procedures such as fractional and alexandrite lasers have been established as treatment modalities for this purpose. [9][10][11][12] Ultimately, the drug of choice for AN has not yet been determined, and further trials are required to demonstrate the effectiveness of various modalities. In this single-blinded, randomized trial, we aimed to evaluate the effectiveness of tretinoin 0.05% which is considered the first-line treatment for AN, and to compare it with a 70% glycolic acid peeling solution.…”
