Laser treatments erythema

Persistent erythema, due to angiogenic factors stimulating vasodilatation, is considered a physiological event if it occurs within 3 weeks after the peel procedure [6]. If erythema associated with pruritus persists for more than 3 weeks, treatment with potent topical corticosteroids, systemic corticosteroids, and/or intralesional corticosteroids should be administered. Silicone sheets or pulsating dye laser treatments may be also adopted, especially when evident thickening or scarring has occurred [6, 15]. 

FIGURE 37.4 SLS irritation and moisturizer treatment, (a) No significant differences in skin color (a-values) were detectable with the Chromameter. (b) The same sites as in (a) scanned with the laser Doppler imager showed marked reduction of erythema. Volar forearms were treated with a water-in-oil emulsion twice daily for four weeks. Statistical significance was determined using the paired r-test ( p >. 05, p <. 01). 

A split-face trial, in which one side of the face was treated with the nonablative 1550 nm erbium-doped fractional laser and the other side treated with the CROSS method, has been undertaken. In rolling-type acne scars, the objective and subjective improvement rates have been reported to be significantly higher in the sides treated with nonablative erbium-doped fractional laser than the CROSS method. However, in ice pick type of acne scars, there have been no statistically significant differences between the nonablative erbium-doped fractional laser and the CROSS treatment sides. In the CROSS sides, grades of pain were significantly less than that of the sides treated with laser. However, downtime and duration of erythema were reported to be longer in the sides treated with the CROSS method than with the nonablative erbium-doped fractional laser.
