Hello,
This is a great question!
In the process of research aimed at identifying the underlying cause for vitiligo, scientists have postulated that vitiligo can be triggered by stress to the pigment producing cells of the skin.
Some potential vitiligo triggers have been identified:
- Genetic susceptibility
- Sunburn
- Mechanical trauma (e.g. friction, cuts)
- Chemical exposure
- Low mood / Abnormal emotional stress
Some of my patients have found that after one or a combination of the above-mentioned triggers, they began to notice progressive depigmentation occurring on their skin.
These triggers work to increase oxidative stress in the pigment-producing cells of the skin. There is growing evidence to suggest a role for use of antioxidants as a part of vitiligo therapy, with promising research showing a positive impact on repigmentation rates with the supplementation with certain antioxidants.
Identification of relevant triggers helps with a better understanding of our patients and guides further advice and treatment.
I hope this helps to answer the question!
Best Regards
Dr Christopher Lim
