Methods: 40 volunteers with skin
types II and III were included in the randomized, doubleblind,
placebo-controlled, phase III monocenter study. Test
areas on the back were irradiated with the 1.5-fold minimal
erythema dose of UVB. Subsequently, the test areas were
treated occlusively on 2 subsequent days with A. vera gel
(97.5%), the positive controls (0.25% prednicarbate, 1% hydrocortisone
in placebo gel and 1% hydrocortisone cream)
and a placebo gel. Erythema values were determined photometrically
after 24 and 48 h.
