MARYCOHR Beaute Concentrate New Youth Collagen Serum

MARYCOHR is a French dermo-aesthetic house whose products reach people through salons rather than shelves, and this is its long-running signature — Korean reviewers call it simply the original collagen serum, dating the line to 2003 and treating it as the one bottle the brand is known by. The 100 ml size is itself unusual: one long-time user pointed out that most MARYCOHR serums run 30 to 50 ml, and this one does not.
