What does this retinol and tranexamic acid serum treat?

This serum tackles pigmentation from three angles at once: retinol renews the skin surface, tranexamic acid reduces melanin production directly, and licorice extract adds brightening while calming any retinol-related irritation. Together they're suited to melasma, sun damage, acne scarring and general dullness. It is best introduced gradually, a few nights a week at first.

Retinol renews the skin surface and boosts penetration of the other actives.

Tranexamic acid directly reduces melanin synthesis and transfer.

Licorice extract enhances brightening, counters potential retinol dryness/irritation, and adds anti-inflammatory protection.

Together, they address pigmentation from multiple pathways: production, transfer, and inflammation, while tackling aging concerns like wrinkles and loss of firmness. This makes the serum especially effective for melasma, sun damage, acne scars, and overall dullness. Research and product formulations show that pairing tranexamic acid with licorice extract (and retinol) creates amplified fading of dark spots compared to single-ingredient approaches.
