The evaluation of cell viability by MTT test on human fibroblasts and keratinocytes after application of SLN and SLN containingprednicarbate showed a viability >90%.
Cell viability evaluated by MTT test after application of prednicarbate containing SLN to reconstructed epidermiswas 94.5% (Santos Maia et al., 2000).
This shows a good tolerability of the carrier system by the skin.
