Post-inflammatory hypopigmentation can occasionally occur after Intense Pulsed Light or IPL treatment for certain skin types. Most of the time, the problem is transient and pigmentation changes will resolve gradually with time.
Topical anti-oxidants like Vitamin C serums and mild anti-inflammatory creams can help. Should long-term hypopigmentation occur, treatment of the area can include ultraviolet light and certain lasers.
As hypopigmentation is uncommon with careful usage of the IPL, you should consult a doctor for an assessment. Fungal infection and autoimmune diseases can also cause hypopigmentation. Cheers!
