Cosdbaha TN Tranexamic Acid Niacinamide

After giving birth, I developed large dark spots under my eyes and on my cheekbones. However, after using the TN Serum, which contains tranexamic acid known to be effective for reducing dark spots, they seem to have faded significantly. Cosd-BHA products are made by minimizing miscellaneous additives and maximizing only the necessary ingredients, making them ideal for consumers to select and mix ingredients to suit their preferences.

The texture is watery but slightly sticky, and it uses a dropper. It can be used during the serum-essence step.
