Laser and IPL hair removal work by heating up hair follicles under treatment areas which can cause injury sometimes. Usually, side effects ranges from irritation to discoloration. However, improper use may cause serious side effects such as swelling or even some tiny blisters.

It is not advisable to scrub or rub the area in order to avoid any scarring.

Discoloration / Hyper or Hypo-pigmentation

After IPL or laser treatment, slightly darker or lighter spots may be clearly seen. In case you have dark skin, you might notice lighter spots (white spots) due to the treatment which is called hypopigmentation. This happens because of melanin depletion. If you have light skin, you will notice the opposite as you will notice darker spots which is called hyperpigmentation. This case happens when there is higher levels of melanin than normal. Yet, such a change in the skin is temporary and only lasts 24-48 hours.

In other words, this process is called discoloration. It happens when there is higher or lower amount of melanin in a particular area.

Photosensitivity / Sensitivity To Light

After each IPL hair removal session, your skin becomes photosensitive. So, experts advise to avoid prolonged and unprotected exposure to sunlight for at least two days after and before treatments. There are also some sources of heat other than the sun you are not allowed to be exposed to including steam baths and sauna for 24 hours. This also applies to intense workouts.
