was found&#44; having more men and lighter skin patients in the placebo group whereas skin photodamage was increased in MAL-group individuals&#46; Nevertheless&#44; after performing post hoc sub-group analysis and covariate adjustment&#44; only skin phototype was found to have a role in the main outcome and no relationship was found with age&#46; This finding is very important as we are not aware of any published study reporting such results&#46;

dPDT with MAL was painless&#44; effective and safe for the treatment of global facial photodamage when compared with placebo&#46; This therapy was also useful for the treatment of fine lines&#44; coarse lines&#44; tactile roughness&#44; mottled pigmentation&#44; sallowness&#44; and erythema&#46; Also&#44; in high risk patients&#44; herpes simplex prophylaxis should be considered before sessions&#46; Results obtained are encouraging as dPDT with MAL not only is effective&#44; but also easy to apply and straightforward to be monitored by any dermatologist&#46; Finally&#44; larger studies such as phase III designs with a more objective quantification of photodamage signs are required in order to confirm efficacy but also to evaluate long-term safety and to determine subgroup differences for men and certain skin phototypes&#46;</p></span><span id="sec0105" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0175">Conflict of interest</span><p id="par0275" class="elsevierStylePara elsevierViewall">Methyl aminolevulinate &#40;Metvix<span class="elsevierStyleSup">&#174;</span>&#41;&#44;
