Skin type and sensitivity issues – The Fitzpatrick skin scale categorizes skin types from very fair to very dark. Darker skin has more melanin, which absorbs laser light more easily, increasing the risk of burns. Even those with sensitive or recently tanned skin may experience stronger side effects.

Sun exposure before or after treatment – Skin that is sunburnt, tanned or recently exposed to UV rays is already fragile. Exposing such skin to laser light makes burns more likely. Similarly, skipping sun protection after a session can worsen side effects.

Use of incorrect cooling methods – Cooling devices or gels are used to protect the skin during treatment. If skipped, applied incorrectly or replaced with poor substitutes, the risk of burns increases significantly.

In short, most laser hair removal side effects, especially burns, are linked to poor technique, lack of personalization or neglecting proper skin preparation. Choosing the right professional and following recommended precautions greatly lowers the chances of burns.
