Side effects of laser hair removal

Laser hair removal penetrates the skin to the root of hair follicle through selective photopyrolysis, so as to irreversibly destroy the structure of hair follicle, so as to achieve the effect of inhibiting hair regeneration. Side effects may also occur due to personal physical factors or failure to pay attention to operation methods, including the following aspects:

  1. The depilated part is red;
  2. Some patients may show follicular edema and small wind mass like changes in the skin;
  3. If the laser energy is too high or repeated treatment, blisters, even scabs and scars may appear at the depilated part;
  4. Due to the close distance between the hair follicle and the sebaceous gland, the sebaceous gland may be affected during laser hair removal, resulting in less oil from the depilated part and slightly poor skin moisture.

To sum up, it is suggested that patients should take local cooling after depilation to reduce local discomfort. If it is found that the skin remains red after depilation, or even blisters appear, go to the hospital in time for treatment by a doctor. If only slight redness and follicular edema occur locally, most patients can disappear 1-2 hours after treatment.

It should be noted that the degree and quantity of hair reduction vary from person to person. Some people can achieve satisfactory results quickly, while others need to increase the number of treatments than conventional cases, which should be determined according to the specific situation.
