When it comes to whitening and freckle-reducing ingredients, you will definitely think of niacinamide, arbutin, vitamin C... However, although tranexamic acid is not the most popular, it is the best whitening and freckle-removing ingredient.

What exactly is the legendary tranexamic acid that can really make you whiter? With such doubts, this article summarizes and analyzes the relevant content of tranexamic acid:

What is tranexamic acid?

Tranexamic acid is a protease inhibitor with pharmacological effects such as hemostasis and anti-inflammatory. It can effectively inhibit the activity of tyrosinase (reduce the production of melanin), and can prevent the formed melanin from transferring to surrounding cells, thereby gradually increasing. Eliminates hyperpigmentation (but not very quickly) for whitening purposes, and is considered to have a freckle-removing, blemish-reducing effect.

The mechanism of action of niacinamide whitening is to inhibit the transport of melanin, promote skin metabolism, and accelerate the shedding of melanin on the skin surface (the whitening effect is faster than that of tranexamic acid). It can also repair the skin barrier, moisturize and delay aging.

From a safety point of view, the use of nicotinamide has fewer contraindications and fewer side effects, but tranexamic acid has a certain hemostatic effect, and side effects will occur if used for a long time. The results show that niacinamide has better safety and efficacy than traditional tranexamic acid.

Inhibit the production of melanin, prevent the transfer and transfer of melanin to other cells, and promote the exfoliation and metabolism of the skin epidermis.

The whitening effect of tranexamic acid is mainly to inhibit the production of melanin and prevent the formed melanin from migrating to surrounding cells, thereby preventing the spread and enlargement of dark spots.
