It sounds like you may be suffering from hypopigmentation from IPL use. This can happen with many laser and light treatments, and the risk is higher with overuse of/aggressive laser/light treatments meant for pigmentation removal, as well as in individuals with darker skin.
Your question brings to mind one of my pet topics, which is the overuse of Q-switch laser and IPL toning in medical aesthetics. Many clinics advertise their treatments as a solve it all solution, promoting qswitch/IPL treatments to help with everything from pigmentation to even acne and firming.
Many salons and clinics also repeatedly use IPL for unsuitable darker skin types which results in painful scars. It appeals to the average consumer as well because of the low cost and instant gratification.
It is important to remember that:
1. Qswitch/Picosecond lasers are intended primarily to benefit pigmentation problems, they DO NOT help much with skin tightening, and CERTAINLY NOT for acne! There are much better options for skin tightening and acne, and clinics still using Qswitch lasers for acne reflect a lack of knowledge and/or limited equipment.
2. IPL treatments are NOT SUITABLE for individuals with darker skin.
The first thing you should do is discontinue your IPL treatments. Hypopigmentation after laser and light treatments are particularly hard to treat and you should find a good dermatologist or aesthetic GP with special interest in skin to treat it early.
If you are fortunate, the problem can be transient and may be improved with some topical creams in a short time. Otherwise, it can take many months to even years to improve. Fractional lasers or microneedling are some treatments options, but require a lot of patience.
Consult your dermatologist/doctor early, all the best!
