The Five Most Common Side Effects of Laser Hair Removal

Laser hair removal is a safe and effective way to remove unwanted hair permanently. However, like any medical procedure, some side effects can occur from laser hair removal. In this blog post, we will look at the five most common side effects of laser hair removal and discuss ways to manage them if they occur. Whether you’re considering laser hair removal or already have had the procedure, it is essential to be aware of the treatment’s potential risks and side effects.

Skin Sensitivity

Skin sensitivity is one of laser hair removal’s most common side effects. Laser hair removal can cause redness and irritation to the treated area. It is because the laser energy used to target and remove unwanted hairs can cause a slight burning sensation on the skin’s surface.

The affected area may also become slightly swollen or itchy. Most of these effects should subside within a few hours after treatment. To minimize the impact of skin sensitivity, it is essential to keep the treated area clean and dry and to avoid sun exposure for at least 48 hours after treatment. If you experience any signs of skin sensitivity, contact your healthcare provider for advice on managing them. 

Scarring is another possible side effect of laser hair removal. Although rare, the possibility exists that some patients may experience scarring or hyperpigmentation as a result of their treatments. If this occurs, it is best to consult with a doctor or dermatologist about the possibility of receiving scar-reduction treatments. Blistering is another potential issue that can occur with laser hair removal. Blisters are caused by high heat levels, which damage the skin cells. 


Swelling is one of the most common side effects of laser hair removal. It usually begins within the first few hours after treatment. Swelling is generally mild and temporary and is often localized to the area that has been treated. Swelling can range from mild puffiness to visible bumps. Applying a cold compress to the site may help reduce swelling. If the swelling persists or worsens, you must contact your doctor. 

It is essential to avoid sun exposure for at least a few days after your laser hair removal treatment. Sun exposure can increase the risk of side effects such as skin irritation, burning, and pigmentation changes. If you need to go outside, wear sunscreen with an SPF of at least 30 and cover the treated area with a hat or clothing to protect it from the sun.


One of the most common side effects of laser hair removal is redness. It is caused when the heat generated by the laser damages the cells in the area that’s being treated, causing temporary inflammation and an increase in blood flow to the site. Depending on skin sensitivity, redness can last from a few hours to several days. 

To reduce redness, apply a cold compress or aloe vera gel to the treated area. If the redness does not subside within a few days, you should consult a doctor, as it could be a sign of a more serious issue. Blisters may also occur after treatment due to the laser energy intensity used during treatment. Blisters can appear within one day and usually heal after about a week. In some cases, scarring may also occur, but this is rare. Hyperpigmentation, or darker spots on the treated area, may also occur and usually resolves within a few months.


One of the most concerning side effects of laser hair removal is the potential for blistering. It occurs when the skin is exposed to too much heat during the treatment, and small, painful blisters form. Blistering can be especially dangerous if the blisters burst and become infected, so it’s essential to take extra care if this side effect occurs. If you experience blistering, contact your doctor or dermatologist immediately; they will recommend a course of action. Some treatments involve over-the-counter creams and ointments. Other more severe cases may require antibiotics or other medical treatments. Keeping the treatment area clean and dry is also essential to prevent infection.

Changes in Skin Color

One of the most concerning side effects of laser hair removal is changes in skin color. The most common issue is hyperpigmentation when skin areas become darker than the surrounding areas. It can be caused by several factors, including a too-high energy setting during the laser treatment or even a skin reaction to the ingredients in the anesthetic cream.

Hyperpigmentation can cause discoloration and patches of dark skin. It can also worsen conditions such as melasma, which are dark patches caused by hormones.

Hypopigmentation is another common side effect of laser hair removal. It is when areas of the skin become lighter than the surrounding areas. Hypopigmentation can be caused by over-treating an area with laser hair removal, destroying melanocytes responsible for the pigment in the skin. 

Suppose you’re worried about changes in skin color due to your laser hair removal treatments. In that case, it’s best to speak with your dermatologist or aesthetician before starting treatment. They will be able to advise you on the proper settings to use and provide tips on minimizing risks associated with laser treatments.
