It has been demonstrated that photodamage leads to wrinkles, mottled pigmentation, lentigines, telangiectasias, and textural changes, but more importantly, it can also lead to pre-cancerous conditions with the development of actinic keratosis (AK). The majority of photorejuvenation or photodamaged published studies have used 5-Amino-Levulinic acid (5-ALA) as a photosensitizer, and either a blue light or an Intense Pulsed Light source with a 70%-95% global facial skin improvement. The molecular mechanism of such improvement is unknown, but activation of a non-specific immune response in addition to increased fibrosis and new collagen formation, have both been suggested.
Methyl Aminolevulinate ( MAL) is another marketed photosensitizer mainly utilized in Europe. Lipophilicity, higher penetration depth and tumor selectivity has been advocated for MAL compared to 5-ALA. However, its effect in photodamaged skin has not been well documented.
The aim of the study is to determine the efficacy of MAL + Aktilite (PDT) in facial photodamage.
