Cos De BAHA and MaryenB: one team, two Korean skincare brands

Cos De BAHA started in 2019 as a Korean skincare brand and reached customers in the United States through Amazon. The Cos De BAHA catalog is currently sold out, and we keep every product page and article online as a reference for the formulas many of you search for.

MaryenB is the newer brand from the same team. It is a focused line of six single-active serums: retinol (RNT), tranexamic acid 5% (TNA5), niacinamide 20% (NTZ20), azelaic acid 10% and 5% (ANC10, ANC5) and vitamin C 15% (VNC15). Each one lists the active at a clear percentage.
