Role of different topical modalities in improvement of facial hyperpigmentation and skin rejuvenation
Keywords:Kojic acid, Azelaic acid, 4-n-butyl resorcinol, Tranexamic acid, Glutathione
Background: Facial hypermelanosis is a psychologically stressful condition for modern men and women who are cosmetically more conscious than their ancestors. There are various lightening agent used for several months before effect becomes apparent and are much more effective when pigment is epidermal. these topical agents include hydroquinone, liquorice derivatives niacinamide, glycolic acid, arbutin and deoxyarbutin, ascorbic acid, 4-n-butyl resorcinol, retinoids topical steroids mequinol, kojic acid, azelaic acid, 5% tranexmic acid, glutathione cream etc.
Methods: A randomized, controlled study was done. 220 patients were given either treatment will be given depending upon the physician choice after taking well informed consent from the patient. Patients' assessment regarding the degree of improvement of complexion since the beginning of therapy was evaluated.
Results: The percentage satisfactory response for different modalities was as follow kojic acid 2% cream- 55.55%, 20% azelaic acid cream- 53.12%, 4-n-butyl resorcinol 0.3% cream- 57.89%, 5% tranexmic acid lotion- 48.83% and glutathione cream- 55.76%.
Conclusions: Out 220 patients post inflammatory hyperpigmentation was the most common facial condition. Total 61 patients of PIH were there in the present study including 26 males and 35 females followed by melasma. All The modalities were effective in the treatment of different types- pigmentary conditions.
