The Ordinary Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F 30ml

Product Information

Immunostained slides were mounted with anti-fading medium (Fluoromount™, Sigma Aldrich, St. Louis, MO) and imaged with a Nanozoomer S360 Digital Slide Scanner (Hamamatsu Photonics, Hamamatsu, Japan) and NDP.view2 software (Hamamatsu Photonics, Hamamatsu, Japan). Procollagen type I and tropoelastin expression was determined by calculating the percentage area of the dermis using Image J software (NIH, Bethesda, MD). A total of 64 images per experimental condition were analyzed (2 donors per experimental condition; 2 skin explants per donor; 2 tissue sections per explant; 8 images per tissue section). Statistical analysis was performed considering the mean values of both donors using a Games-Howell post hoc test to compare between conditions. A p value less than 0.05 was considered significant. Ethical Approval and Informed Consent Of course, it has. Vitamin C always has the potential to be irritating, especially if you have sensitive skin.
