Skincare, simply explained
If dark marks linger after a breakout or your skin looks uneven, tranexamic acid is an ingredient to get to know. It appears in leave-on serums and creams designed to help discoloration look less noticeable over time.
TXA-containing formulas may help areas of uneven pigmentation look more balanced with regular use.
Some combination serums have improved the appearance of brown marks left after blemishes. Those flat marks are different from indented scars.
It is often paired with niacinamide and other brightening ingredients, allowing several tone-focused ingredients to fit into one product.
Tranexamic acid, often shortened to TXA, is a manufactured compound related to the amino acid lysine. In skincare, it is used in formulas for dark spots, post-blemish marks and uneven-looking pigmentation. It is usually part of a leave-on serum or cream.
The word acid can make it sound like an exfoliant, but TXA has a different job from glycolic or lactic acid. Research focuses on its role in the signals involved in pigment production, rather than loosening dead surface skin cells. That explains its place in brightening formulas.
TXA is often combined with other tone-focused ingredients, including niacinamide. A serum can bring these ingredients together in one step, while a cream combines them with moisturizing care. The TXA abbreviation and Tranexamic Acid refer to the same ingredient.
