Choosing Between Tranexamic and Azelaic Acid

Uneven skin tone often requires a shift in maintenance strategy rather than a change in foundation shade. Both tranexamic acid and azelaic acid serve as standard topicals for managing the appearance of surface-level pigment. Selection between the two rests on your specific skin type and the nature of the discoloration you intend to address.

This guide establishes how to implement one of these ingredients into your evening routine to achieve consistent results. By focusing on a single agent, you minimize the risk of over-application while assessing efficacy.

1. Cleanse the skin. Begin with a neutral, non-foaming cleanser to remove debris. Pat the skin completely dry with a clean towel. Residual moisture can alter the penetration of the active ingredient.
2. Apply the active. Dispense three drops of your chosen acid onto your fingertips. Apply in an even, thin layer across the affected zones. Allow the product to dry down fully for sixty seconds before proceeding.
3. Seal with moisture. Apply a basic, fragrance-free moisturizer to lock in the product. This creates an occlusive barrier that prevents transepidermal water loss. Ensure the moisturizer does not contain additional exfoliating agents.
4. Protection phase. The efficacy of your nightly routine depends on daytime sun avoidance. Apply a broad-spectrum mineral sunscreen every morning. Failure to do so will reverse any progress made during the evening.

Consistency over intensity dictates the success of any topical acid regimen.
