CAN I LAYER THIS WITH OTHER INGREDIENTS? Yes! It’s safe to use this serum for hyperpigmentation with all other products AM + PM. Just wait 30 mins before applying moisturizer.

WHY DID THE NAME CHANGE? We renamed it from Tranexamic Acid Night Treatment in Spring 2022 to reflect AM + PM use. Formula hasn’t changed.

CAN I USE THIS ON MY BODY? Yes, apply to any area with hyperpigmentation. Always patch test first.

IS IT SAFE FOR LONG-TERM USE? Absolutely. Use it consistently for best results.

IS THIS SAFE FOR SENSITIVE SKIN? Tranexamic Acid is one of the gentlest brightening ingredients available. However, we always recommend patch testing first.

WHAT MAKES TRANEXAMIC ACID GOOD FOR HYPERPIGMENTATION? It helps reduce dark spots by blocking melanin transfer + calming inflammation.

CAN IT HELP WITH BREAKOUTS? It doesn’t treat breakouts, but helps fade post-blemish marks. Plus, Acai + Vitamin C help defend against stressors that can trigger spots.

WILL IT IMPROVE BLEMISH SCARS? Yes, it helps smooth uneven tone and fade marks left behind.

CAN I USE THIS WITH VITAMIN C OR RETINOL? Yes! Tranexamic Acid is gentle and works well with other actives. Use this serum in AM/PM, and layer with Vitamin C in the morning or Retinol at night.

CAN I USE IT WITH NIACINAMIDE? Yes! Layer together in your routine. Wait until fully absorbed before applying moisturizer.

WHAT'S THE DIFFERENCE BETWEEN THIS AND VITAMIN C SERUM? While Vitamin C prevents future damage and brightens overall, Tranexamic Acid specifically targets existing dark spots and hyperpigmentation. For maximum results, many people use both.

WHAT IS TRANEXAMIC ACID AND HOW DOES IT WORK? Tranexamic acid is a gentle yet powerful ingredient that works by blocking the pathways that create excess melanin (the pigment that causes dark spots). Originally used in medicine, it's now a dermatologist favourite for treating hyperpigmentation safely.

IS IT AN EXFOLIATING ACID? No.

HOW LONG DOES TRANEXAMIC ACID TAKE TO WORK? You may notice brighter skin in 2-4 weeks, with significant improvement in dark spots and hyperpigmentation typically visible after 6-8 weeks of consistent use.
