Expensive but feels very moisturising Review: Lo compré por el precio ya que el producto es mucho más caro en su web, cierto que una vez aplicado no deja ningún residuo pero es muy denso y cuesta un poco aplicarlo. Por lo demás la calidad es de Allis of Skin, no defrauda. ## Features - ADVANCED 20% VITAMIN C SERUM FOR ALL SKIN TYPES.
