What is a normal reaction after treatment and what is not?

When undergoing Laser Hair Removal, having a skin reaction in the following hours or days is expected and often even a sign that the treatment is going well. But how can you know that what you are experiencing is normal or not?

These reactions are usually mild and should subside within a few hours to a few days. Here are some normal reactions you may expect:

  • Redness: The treated area may appear slightly red immediately after the procedure. This redness is typically similar to a mild sunburn and should fade away within a few hours.
  • Swelling: Some degree of swelling may occur, especially around sensitive areas like the upper lip or bikini line. It is usually minor and resolves within a day or two.
  • Skin Sensitivity: The treated skin might feel more sensitive than usual, and you may experience a mild sensation of heat or tingling. This sensitivity should diminish within a few hours.
  • Itching: You may experience itching in the treated area as the hair starts to shed. This is a normal part of the hair removal process and should not last long.
  • Peeling or Crusting: In some cases, the treated skin may develop a temporary crust or scab, particularly if the laser was used at higher settings or on more delicate skin. Avoid picking or scratching these areas to prevent infection and allow them to heal naturally.
  • Changes in Pigmentation: Temporary changes in skin color are possible, especially for individuals with darker skin tones. The treated area might appear slightly darker or lighter, but this usually resolves within a few weeks.

If you are feeling any of these, you can always apply Hydrocortisone 1% on the area two or three times a day until the irritation is gone. It is always important to follow the after care in detail to make sure your skin gets the proper rest after a Laser Hair Removal Treatment. 

While most reactions after laser hair removal are considered normal and temporary, there are certain symptoms that may indicate an abnormal or potentially concerning reaction. If you experience any of the following, it is recommended to seek medical attention:

  • Severe or Prolonged Pain: It is normal to experience some discomfort during and immediately after the procedure. However, if you have intense or persistent pain that is not relieved by over-the-counter pain medications, it could be a sign of an abnormal reaction or complication.
  • Excessive Swelling or Blisters: While some swelling is expected, excessive swelling or the development of blisters larger than a quarter may indicate a more severe reaction. This could be a sign of a burn or infection, and medical attention should be sought.
  • Severe Redness or Heat: While mild redness and warmth are normal, if the treated area becomes significantly red, hot, or feels unusually warm to the touch, it may indicate an adverse reaction or infection.
  • Oozing, Crusting, or Infection: If the treated area starts to ooze pus, develop a thick crust, or shows signs of infection such as increased pain, redness, warmth, or a spreading rash, it is important to consult a healthcare professional promptly.
  • Persistent or Worsening Skin Changes: While temporary changes in pigmentation are normal, if you notice persistent or worsening darkening or lightening of the skin that doesn't improve over time, it's best to consult with a medical professional.
  • Any other concerning symptoms: If you experience any other unusual or concerning symptoms that you suspect may be related to the laser hair removal treatment, it is advisable to consult with a healthcare professional for evaluation and guidance.

Remember, these are potential signs of abnormal reactions, but they are relatively rare. It is very important to always follow the pre and post care protocols and choose a Laser Center that has experience, specially with different skin tones, where the technicians are licensed, the technology being used is recent and with strict disinfection guide lines.
