Brief Summary:
Treatment of actinic damage has included multiple procedures but to date there is limited scientific evidence to support the preferential use of one of these therapies according to their efficacy, safety and pain tolerance by patients. This study aims to assess the efficacy of methyl aminolevulinate + daylight vs placebo + daylight to treat facial photodamage

Condition or disease Intervention/treatment Phase
Facial Photodamage Drug: Methyl Aminolevulinate (MAL) Drug: Placebo Phase 2

Arm Intervention/treatment
Experimental: Methyl Aminolevulinate (MAL)
1 gram of Topical Methyl Aminolevulinate (MAL) applied to the whole face 30 minutes before sun exposure for 2 hours (3 sessions , 2 to 4 weeks apart)
Drug: Methyl Aminolevulinate (MAL)
Other Name: Metvix®

Placebo Comparator: Placebo
1 gram of placebo cream applied to the whole face 30 minutes before sun exposure for 2 hours (3 sessions , 2 to 4 weeks apart)
Drug: Placebo
Other Name: Vehicle




Primary Outcome Measures :
  1. Global photodamage improvement [ Time Frame: 1 month after third session ]
    The primary outcome is global photodamage improvement 1 month after the third daylight PDT session, according to Dover´s photodamage scale.


Secondary Outcome Measures :
  1. Pain measurement [ Time Frame: After 2 hours of sun exposure in each session ]
    Pain evaluation with the visual analogue scale after 2 hours of sun exposure in each of the sessions performed (Sessions 1, 2 and 3).

  2. Specific Photodamage score [ Time Frame: 1 month after the third session ]
    Specific photodamage severity score for fine lines, coarse lines, tactile roughness, mottled pigmentation, sallowness, and erythema one month after the third daylight PDT session, according to Dover´s photodamage scale.

  3. Sun irradiance and illuminance quantification [ Time Frame: During the 2 hours of each session ]
    Sun irradiation and illuminance quantification during exposure

  4. Adverse events [ Time Frame: From recruitment until 1 month after the third session ]
    Any adverse event

  5. Therapy tolerance [ Time Frame: 1 week after sessions 1,2 and 3 ]
    Therapy tolerance will be recorded with a scale that includes a 4-grade severity score for oozing, erythema, oedema, desquamation, pigmentation, and vesiculation.

  6. Quality of life assessment (Skindex-29 Instrument) [ Time Frame: Basal and 1 month after the third session ]
    Quality of life assessment (Skindex-29 Instrument)
