Our philosophy

Rooted in dermatology.
Made for daily life.

d:tology began with dermatologist Dr. Wonwoo Choi's interest in developing a soothing formula for the visible redness he observed after laser procedures. What began in a clinical setting evolved into a skincare brand centered on considered, everyday care.
