5 Common (and Rare) Laser Hair Removal Side Effects

Laser Hair Removal Side Effects: Key Points

---

• Temporary changes in skin pigment or redness are common side effects of laser hair removal

• Rare side-effects of laser hair removal include crusting, scabbing, and skin texture changes

• Post-treatment skin care can help minimize irritation and promote healing 

• People with certain health conditions, such as herpes simplex virus (HSV), may not be good candidates for laser hair removal

Laser hair removal is safe for most individuals, but using the wrong laser type for a person’s skin tone can cause side effects.

In fact, using shorter wavelength lasers for hair removal increases the likelihood of skin pigment changes, affecting up to 19% of cases, especially in darker skin tones.

In comparison, the risk drops to just 2-3% with Nd:YAG (neodymium-doped yttrium aluminum garnet) lasers, which are more suitable for dark skin.

Here’s what we’ll cover:

• Common laser hair removal side effects you should be aware of

• Tips for preventing further irritation after your session

• Why Laser by Aleya is a trusted provider for safe laser hair removal treatments

Common Side Effects of Laser Hair Removal

Laser hair removal is generally safe and effective for most individuals if a qualified laser specialist performs it. 

However, the procedure might cause temporary side effects following the treatment, such as: 

1. Redness and Irritation 

Redness or a sunburn-like sensation often occurs shortly after a laser session, as the laser targets hair follicles and heats the surrounding skin. 

2. Swelling Around Hair Follicles 

Mild swelling, especially in areas with thicker hair like the underarms, is common and usually subsides within a few hours. 

3. Temporary Skin Discomfort 

You may feel tingling or slight stinging during or shortly after the procedure, with discomfort levels varying according to your pain tolerance and the treatment area. 

4. Pigment Changes 

Some people may experience temporary skin darkening (hyperpigmentation) or lightening (hypopigmentation), especially those with darker skin tones or those exposed to the sun soon after treatment.

5. Dryness or Flaking

Laser treatments can temporarily disturb the skin’s moisture barrier, resulting in mild dryness or flakiness.

Rare Side Effects of Laser Hair Removal 

Unfortunately, rare side effects can occur from improper treatment by the laser specialist or inadequate aftercare. 

1. Crusting or Scabbing 

Crusting or small scabs might develop if the skin becomes excessively dry or irritated after treatment. 

2. Scarring 

Scarring might result from improper laser techniques, aggressive treatment settings, or scratching healing skin. 

 3. Changes in Skin Texture 

Whether it’s roughness or indentations, some individuals might notice changes in the texture of their skin following a laser hair removal session. 

These usually occur when the skin reacts poorly to the laser’s heat. 

4. Excessive Hair Growth in the Treatment Area 

In rare cases, laser treatments can trigger paradoxical hypertrichosis — an unexpected increase in hair growth in or near the treated area. 

This occurs more often in people with darker skin tones or when lasers operate at low energy settings. 

Side Effects of Laser Hair Removal on the Bikini Area

Here are short-term laser hair removal side effects you might experience on the bikini area:

• Localized swelling: Mild swelling around hair follicles is common, particularly in sensitive areas like the bikini line. According to the American Academy of Dermatology (AADA), this typically subsides within one to three days. 

• Redness and irritation: Right after your session, the treated skin may appear pink or feel warm. This irritation typically fades within a few hours. 

• Temporary skin discoloration: You might notice slight darkening or lightening of the skin in the treated area. These pigment changes are usually temporary but can persist longer in darker skin tones. 

• Itching and tingling: You may feel mild itching or tingling during the treatment or shortly afterward. 

• Sensitivity: The treated area might feel warm or tender to the touch for several hours following the treatment. 

Does Laser Hair Removal Cause Cancer?

According to the Cancer Council, laser hair removal doesn’t cause cancer. 

This misconception stems from confusion about the radiation type used. 

Laser hair removal uses non-ionizing radiation, which doesn’t damage DNA or alter cell structure. 

Unlike ionizing radiation (such as X-rays or UV rays), non-ionizing laser energy specifically targets the hair follicle, heating and disabling it without affecting surrounding skin or penetrating deeply enough to pose a cancer risk.

Does Laser Hair Removal Cause Infertility?

No, laser hair removal doesn’t cause infertility.

There’s no clinical evidence that laser hair removal causes infertility, as the procedure only affects the skin’s surface and doesn’t appear to affect the reproductive organs.

Is Laser Hair Removal Harmful for Expecting Mothers?

Experts don’t recommend laser hair removal for pregnant women. 

The American Pregnancy Association states that while there’s no evidence to suggest laser hair removal is harmful during pregnancy, there’s also no conclusive proof of its safety. 

Given this uncertainty, many healthcare providers recommend avoiding laser hair removal during pregnancy to prevent any potential effects on the fetus. 

Who Should Avoid Laser Hair Removal?

While laser hair removal is generally safe, it’s not suitable for everyone.

Certain medical conditions can increase skin sensitivity, raising the risk of adverse reactions from laser hair removal. 

For instance, individuals with a history of herpes simplex virus (HSV) outbreaks should be cautious, as laser hair removal might trigger a recurrence of these outbreaks due to skin irritation. 

A safe and effective treatment always begins with knowing who should wait or avoid the procedure entirely. 

Individuals considering laser hair removal should be cautious if they have any of the following conditions: 

• Active skin infections, including open wounds 

• A history of HSV outbreaks 

• A history of keloid scarring 

• Light hair color 

How To Reduce Laser Hair Removal Side Effects

You can help minimize the risk of side effects from laser hair removal by taking these straightforward precautions:

1. Follow Pre-Treatment Guidelines

Avoid tanning, waxing, or plucking for at least four weeks before your appointment. On the day of your session, keep the area clean and skip lotions, deodorants, or perfumes. 

2. Keep the Area Moisturized

Hydrate the treated skin with a fragrance-free lotion or pure aloe vera gel. Avoid using heavy or greasy products that could clog pores or irritate the skin.

3. Stay Out of the Sun

Limit sun exposure for at least 48 hours post-treatment. If you need to go outside, wear a broad-spectrum sunscreen with SPF 30 or higher to protect the area.

4. Avoid Heat and Friction

Skip hot showers, saunas, and tight clothing for at least 24 to 48 hours after your session, as these can delay healing.

5. Don’t Scratch or Pick the Skin

Itching is normal, but avoid touching, scratching, or picking at the treated area to prevent irritation or infection.

6. Use a Cold Compress After Treatment

Apply a cold compress for 10 to 15 minutes to reduce redness and swelling.

7. Follow All Aftercare Instructions

Follow your laser specialist’s post-treatment plan, adhere to product and skin recommendations, and attend follow-up sessions as needed for optimal results.

Benefits of Laser Hair Removal

While laser hair removal comes with some drawbacks, it is generally a safe and effective way to reduce unwanted hair. 

With consistent treatment, you can expect smoother skin and fewer long-term maintenance needs.  

1. Delivers Long-Lasting Results 

Laser hair removal significantly slows hair growth, allowing many individuals to enjoy smooth skin for extended periods with only occasional touch-ups. 

2. Targets Hair With Precision 

The laser targets dark, coarse hairs without harming surrounding skin, making it ideal for sensitive areas like the bikini line, face, and underarms. 

3. Prevents Ingrown Hairs

Laser hair removal disables the follicle to prevent ingrown hairs, reducing the bumps, redness, and irritation often caused by shaving or waxing. 

4. Saves Time 

After completing a series of treatments, you’ll spend less time on routine hair removal, eliminating daily shaving and frequent waxing appointments. 

5. Improves Skin Texture 

Laser hair removal makes skin smoother and reduces common side effects like razor burn and post-wax breakouts.
