Topical 5% Tranexamic Acid as a Treatment for Postinflammatory Hyperpigmentation Due to Acne Vulgaris
Study Details
Study Description
Brief Summary
The goal of this study is to determine if topical tranexamic acid is capable of decreasing the pigment of the dark spots left from acne bumps. The first line medication used for this often is not tolerated well by patients, and topical tranexamic acid has minimal reported side effects thus far.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Right Side of Face Patients will apply topical tranexamic acid to the dark spots on the one side of their face. |
Drug: Tranexamic Acid
Topical tranexamic acid in cream form applied to dark spots on right side of face.
|
| Sham Comparator: Left Side of Face Patients will apply the vehicle cream without any medication to the dark spots on one side of their face. |
Drug: Vehicle
The Vehicle is going to be a cream without any active medication that will be applied as a control substance for the topical tranexamic acid cream, and will be applied to the contralateral side of the face.

Outcome Measures
Primary Outcome Measures
- Change from Baseline Pigmentation at 4 Weeks. [4 Weeks.]
Patients will have their lesion pigmentation scored with the postacne hyperpigmentation index after 4 weeks. The postacne hyperpigmentation index (PAHPI) assesses hyperpigmentation lesions after acne based on the median lesion size, the median lesion intensity, and the number of lesions present. The total score can range from 6-22 points. Subscales will measure lesion size, lesion intensity, and number of lesions. Subscales will be assigned a number based on the table in the protocol, and then added together to form the total score. Higher values indicate worse hyperpigmentation. We will measure the total decrease in the PAHPI at the follow-up visit.
- Change from Baseline Pigmentation at 8 Weeks. [8 Weeks]
Patients will have their lesion pigmentation scored with the postacne hyperpigmentation index after 8 weeks. The postacne hyperpigmentation index (PAHPI) assesses hyperpigmentation lesions after acne based on the median lesion size, the median lesion intensity, and the number of lesions present. The total score can range from 6-22 points. Subscales will measure lesion size, lesion intensity, and number of lesions. Subscales will be assigned a number based on the table in the protocol, and then added together to form the total score. Higher values indicate worse hyperpigmentation. We will measure the total decrease in the PAHPI at the follow-up visit.
- Change from Baseline Pigmentation at 12 Weeks. [12 Weeks]
Patients will have their lesion pigmentation scored with the postacne hyperpigmentation index after 12 weeks. The postacne hyperpigmentation index (PAHPI) assesses hyperpigmentation lesions after acne based on the median lesion size, the median lesion intensity, and the number of lesions present. The total score can range from 6-22 points. Subscales will measure lesion size, lesion intensity, and number of lesions. Subscales will be assigned a number based on the table in the protocol, and then added together to form the total score. Higher values indicate worse hyperpigmentation. We will measure the total decrease in the PAHPI at the follow-up visit.
