Dark spots: this revolutionary ingredient will transform your skin!
Long used in medicine for its antifibrinolytic properties, tranexamic acid is now established as a key ingredient in skincare products designed to even out skin tone and combat hyperpigmentation. Discover how this active ingredient works and how to effectively incorporate it into your skincare routine.
What is tranexamic acid?
Tranexamic acid is a synthetic derivative of lysine, an essential amino acid. Initially used in medicine to limit excessive bleeding, it has recently been found to have benefits in cosmetics for reducing hyperpigmentation and improving skin tone uniformity.
How does it affect the skin?
Tranexamic acid acts on several mechanisms responsible for the formation of pigment spots:
- Inhibition of melanin production It prevents excessive stimulation of melanocytes, the cells responsible for producing melanin.
- Anti-inflammatory action It reduces skin inflammation, which is frequently associated with post-inflammatory hyperpigmentation, particularly after an acne flare-up or excessive sun exposure.
- Blocking melanin transfer : It limits pigment migration to the skin's surface, thereby preventing the appearance of new spots.
Why incorporate it into your skincare routine?
Tranexamic acid is particularly recommended for treating:
- Melasma (pigmentation spots caused by hormonal fluctuations)
- Sunspots (caused by UV exposure)
- Post-inflammatory hyperpigmentation (due to acne scars or skin irritation)
It is gentle on all skin types and can be incorporated into a daily routine for a more even and radiant complexion.
How to use it properly
Tranexamic acid is found in various types of skincare products such as serums, creams, and lotions. For optimal effectiveness:
- Apply a product containing between 2% and 5% of tranexamic acid, once or twice a day
- Combine it with other complementary assets such as niacinamide or the vitamin C to strengthen its action.
- Use daily sun protection (SPF 30 minimum) to prevent new spots from appearing.
Precautions and side effects
Although generally well tolerated, tranexamic acid may cause mild irritation in sensitive skin. It is therefore recommended that you perform a skin test before incorporating it into your routine.
