Skin care products containing tranexamic acid are the most popular products on the market today. The following will introduce the efficacy and principle of tranexamic acid, and answer whether pregnant women can take tranexamic acid and its adverse reactions.

What is tranexamic acid?

Tranexamic acid is widely used in medicine as a blood coagulant. Some people can take oral whitening and lightening, but take it under the guidance of a doctor. It is also a skin care product that can whiten and lighten spots, but the effect is not very good. Combined with other whitening ingredients, the effect will be better.

Does tranexamic acid work for external use?

Tranexamic acid was initially valued for its fair skin after taking it, and the efficacy of this ingredient on melasma has also been verified a lot.

External application can also play a role, but there are three ways to whiten and fade spots: 1. Block the production of melanin; 2. Block the metabolism of black.

Tranexamic acid is safe and reliable for external use. After a lot of experiments, you don't have to worry. The overall nature of tranexamic acid is relatively mild and does not cause any irritation to the skin.

What is the effect of tranexamic acid?

Efficacy 1. The composition of tranexamic acid and VC is different. It plays a very good inhibitory role in the process of inhibiting melanin. The main function is to inhibit the production of melanin in the front.

Efficacy 2. Tranexamic acid can inhibit the prostaglandins secreted by keratinocytes, thereby activating the formation of melanin, thereby prompting melanocytes to produce melanin. Tranexamic acid can inhibit PGE2, which can inhibit the front-end melanosomes and keratinocytes produced by the skin after ultraviolet radiation.

Efficacy 3. Tranexamic acid has a significant inhibitory effect on the expression of PAR-2. PAR-2 ​​can promote the diffusion of melanosomes into keratinocytes, resulting in skin blackening and pigmentation. This ingredient can also prevent melanosomes. Spreads to the keratinocytes for a whitening and blemish-free effect.

Efficacy 4. Tranexamic acid can significantly inhibit PAR-2, and has a certain inhibitory effect on rosacea and skin inflammation.

Tranexamic acid is so widely used because of its stability, not other ingredients. Although the data in the laboratory is good, the stability is very poor. After the product is produced and stored, the After using it, the active substances in it will be exhausted, and it will no longer have any effect.

Who should not take tranexamic acid?

Although tranexamic acid is stable, mild and non-irritating, many research institutions have proven its safety. However, because this ingredient has unique hemostatic properties and may cause some adverse effects, it is not suitable for everyone looking to lighten spots:

(1) It is not suitable for use during pregnancy and breastfeeding. It is harmless to adults, but may have an impact on the baby's body.

(2) For women with low menstrual flow, due to long-term heavy use, there is a risk of irregular menstruation. In the case of women with small menstrual flow, it should be used with caution (small doses can be used externally).

(3) If it is a patient with qi stagnation and blood stasis, it should be used carefully to avoid causing qi stagnation and blood stasis.

(4) It is not suitable for people with dark yellow skin. The yellowing of the skin has nothing to do with melanin, mainly due to lack of qi and blood. If there are dark spots on the skin, tranexamic acid can be used to whiten and lighten the spots. If the skin has yellow spots, then you must pay attention to regulating qi and blood, and do not blindly use whitening products such as tranexamic acid.
