What is tranexamic acid?
Tranexamic acid is a star ingredient for hyperpigmentation! Tranexamic acid is a synthetic derivative of the amino acid L-lysine. Tranexamic acid is a synthetic derivative of the amino acid L-lysine. L-lysine is an amino acid that is found in our food and supplements. For example, Tofu is a delicious and great source of it! Tranexamic acid is a bioequivalent of L-lysine which means they’re like twins. When something is bioequivalent, it means that our bodies recognize it and use it in the same way. Here are 4 reasons tranexamic acid lessens hyperpigmentation
Here’s another good thing about Tranexamic acid: it helps to decrease some of the inflammation that happens because of UV light. UV causes a mini-inflammatory response, and a protein called plasmin that helps with clotting (making a bleed to stop) is transported to the irradiated (affected) skin by immune cells (cells that fight attack). However, this is all an inflammatory process. Things are going on red alert. With that, more tyrosinase activity is triggered. So now, more melanin is produced, and of course, it goes to the top layer of your skin. To provide another example, you know how you get a cut and then it heals, but then the area is a bit browner than the rest of your skin? The same effect can happen with exposure to UV light, but tranexamic inhibits or hinders this.
Tranexamic acid is also “anti-angiogenic.” That means it decreases the amount of blood vessels being produced. This is important because blood vessels will actually feed melanocytes. A melanocyte holds the melanin, but an overproduction of melanin leads to hyperpigmentation. So, on so many levels, tranexamic acid is a great option for hyperpigmentation!
