Nonablative laser is effective against rosacea by remodeling of the dermal connective tissue and improving the epidermal barrier. [18] The major disadvantage of this therapy is its cost because it is not covered by insurance. It requires 1-3 treatments 4-8 weeks apart to achieve the best results.

Vascular lasers are the mainstay of rosacea therapy. These include pulsed dye laser (585 or 595 nm), the potassium-titanyl-phosphate laser (532 nm), and the diode-pumped frequency-doubled laser (532 nm). These wavelengths allow selective absorption by oxyhemoglobin, leading to vessel reduction with minimal damage to surrounding tissue or scarring. To be effective against deeper facial vessels, longer wavelengths of lasers are required, including the diode laser (810 nm), the long-pulsed Alexandrite laser (755 nm), and the long-pulsed Nd:YAG laser (1064 nm).

Intense pulsed-light therapy is a multichromatic laser with different targets, including melanin and hemoglobin. Therefore, it is also useful for facial rejuvenation, affecting vascular lesions, pigmented lesions, and hair.
