Rosacea is a common disfiguring skin condition that often presents with flushing, erythema, papules, pustules, and dilated capillaries on the face, worsens with heat, correlates with mood changes, and is aggravated by UV exposure.

Liquid nitrogen spray stimulation is an effective method for treating rosacea erythema and capillary dilation.

Rosacea of the erythematous type is suitable for treatment with liquid nitrogen spray freezing. 2. Botox injection treatment. It is also an effective method of rosacea treatment.
