Outcome Measures

Primary Outcomes (4)

  • Measurement of melanin index to assess change of post-acne hyperpigmentation

    the melanin index (MI) average is 1.10 +/-0.29 with higher values showing worse outcome. It will be measured using reflectance spectrophotometer in order to assess the degree of hyperpigmentation

    3 months

  • Measurement of erythema index to assess change of post-acne hyperpigmentation

    the erythema index (EI) average is 1.29 +/- 0.38 with higher values showing worse outcome. It will be measured using reflectance spectrophotometer in order to assess the degree of erythema

    3 months

  • Measurement of post-acne hyperpigmentation index to assess change of post-acne hyperpigmentation

    the post-acne hyperpigmentation index (PAHPI) ranges from 6-22 with higher values showing worse outcome. It is a summation of three scores (Postinflammatory hyperpigmentation(PIH) lesion size, median lesion intensity compared with surrounding skin and the number of PIH lesions).

    3 months

  • Patient satisfaction score to assess change of post-acne hyperpigmentation

    It is a score ranging from 1-4 with improvement 0-25%=1, 26-50%= 2, 51-75%=3 and more than 75%=4 so higher values of patient satisfaction score showing better outcome

    3 months

Study Arms (2)

Tranexamic acid injection (Kapron)

EXPERIMENTAL

One side of the face will be assigned to TXA intradermal microinjection using Kapron 500mg/5ml ampoules (Amoun Pharmaceutical Company), the dose of 1 ml syringe with 100mg/ml. TXA will be prepared under sterile conditions. Injections will be applied intradermally on hyperpigmented areas at 1cm intervals. The injection will be repeated every two weeks for three months.

Drug: Tranexamic Acid

Fractional CO2 laser resurfacing

ACTIVE COMPARATOR

The other side of the face will be randomly assigned to do low power fractional CO2 laser with a power of 12 watts, spacing 700 micrometers (low density), and dwell time 300 microsecond every four weeks for three months.

Device: Fractional CO2 laser

Interventions

One side of the face will be assigned to TXA intradermal microinjection using Kapron 500mg/5ml ampoules (Amoun Pharmaceutical Company), the dose of 1 ml syringe with 100mg/ml. TXA will prepared under sterile conditions. Injections will be applied intradermally on hyperpigmented areas at 1cm intervals. The injection will be repeated every two weeks for three months.
