Laser hair removal has become one of Australia’s most popular cosmetic procedures, offering a long-term solution to unwanted hair. However, questions about safety, side effects, and myths surrounding the treatment often cause hesitation.
Is laser hair removal harmful? What are the risks involved, especially for sensitive skin? This guide breaks down the facts, debunks common myths, and explains everything you need to know about laser hair removal safety.
Let’s Get Straight to the Point
For those short on time, here’s a quick summary:
✅ Laser hair removal is safe when performed by trained professionals using approved devices.
✅ Side effects are minimal—redness and slight irritation may occur but usually subside within a few hours.
✅ Not suitable for everyone—people with certain skin conditions, very light hair, or darker skin tones should consult a specialist first.

Now, let’s separate facts from fiction and thoroughly explore laser hair removal safety.
Laser Hair Removal Safety Facts
1. How Does Laser Hair Removal Work?
Laser hair removal works by directing concentrated light energy at hair follicles, heating them to slow down or prevent future hair growth.
The laser specifically targets melanin (the pigment in the hair), making it most effective on darker hairs against lighter skin. However, advancements in laser technology have led to improved options for individuals with darker skin tones.
The procedure is typically performed by trained professionals using medical-grade laser devices that adjust settings based on skin and hair type. Depending on the treatment area, sessions usually take 10 to 60 minutes, and multiple sessions are required for lasting results.
2. Is Laser Hair Removal Harmful?
When performed correctly, laser hair removal is not harmful. The technology has been refined over decades, and modern laser devices have built-in cooling mechanisms to protect the skin.
However, if performed incorrectly—such as using the wrong laser settings or undergoing treatment from an unqualified provider—there is a risk of burns, hyperpigmentation, or scarring.
Following post-treatment care instructions, such as avoiding sun exposure, is important to reduce the risk of complications. People with a history of keloid scarring or light-sensitive conditions should consult a professional before treatment.
Myths About Laser Hair Removal
1. “Laser Hair Removal Causes Cancer”
A common concern is that laser hair removal might lead to cancer. However, the lasers used in these treatments do not emit ionising radiation, which is linked to cancer development. Instead, they use non-ionising radiation, which affects only the targeted hair follicles without impacting deeper tissues or internal organs.
No scientific evidence suggests that laser hair removal increases cancer risk. Regulatory bodies, including the Therapeutic Goods Administration (TGA) in Australia, approve using medical-grade lasers for cosmetic procedures.
2. “It’s Extremely Painful”
Although pain tolerance varies from person to person, laser hair removal is generally described as mildly uncomfortable rather than painful. Most patients liken the sensation to a rubber band snapping against the skin. Newer laser technology has built-in cooling features that significantly reduce discomfort.
Numbing creams can be applied before treatment for those with low pain tolerance. Additionally, certain body areas, such as the underarms and bikini line, may be more sensitive than others.
3. “Laser Hair Removal Doesn’t Work on Dark Skin”
In the past, laser hair removal was less effective for individuals with darker skin tones due to the risk of pigmentation changes. However, advancements such as the Nd:YAG laser now allow for safer and more effective treatments on a wider range of skin tones.
The key is to visit a reputable clinic with professionals experienced in treating different skin types. Personalised settings can be adjusted to reduce the risk of burns or pigmentation issues.
4. “You Only Need One Session”
Laser hair removal does not provide instant, permanent results. Hair grows in different cycles, and laser treatment is only effective during the active growth phase (anagen phase). Because not all hairs are in this phase simultaneously, multiple sessions—typically 6 to 10—are required for optimal results.
After completing the initial sessions, maintenance treatments may be needed every few months to keep hair regrowth minimal.
Safety Concerns with Laser Hair Removal
1. Laser Hair Removal and Skin Risks
While laser hair removal is generally safe, certain risks exist, especially when treatments are performed incorrectly or on unsuitable skin types. The most common skin risks include:
- Redness and Irritation – A temporary reaction that usually subsides within a few hours to a day.
- Hyperpigmentation and Hypopigmentation – Skin discolouration can occur using the wrong laser settings.
- Blistering and Burns – This is more likely when laser intensity is too high or if performed on tanned skin.
- Scarring – Rare, but possible if aftercare instructions are not followed properly.
Proper pre-treatment consultation and choosing a qualified professional significantly reduce these risks.
2. Is Laser Hair Removal Suitable for Everyone?
Laser hair removal is not suitable for everyone. Factors that may affect suitability include:
- Hair Colour – Light blonde, grey, and red hairs contain little melanin, making them difficult to treat.
- Skin Conditions – Those with eczema, psoriasis, or active infections should avoid treatment.
- Pregnancy – There is limited research on laser hair removal during pregnancy, so it is generally not recommended.
- Medication Use – Some medications, such as isotretinoin, can make skin more sensitive to laser treatments.
A consultation with a professional can help determine whether laser hair removal is the right option for you.
Risks of DIY Laser Hair Removal
Why At-Home Laser Hair Removal Can Be Risky
At-home laser hair removal devices have gained popularity, but they come with certain risks and limitations, such as:
- Lower Power Output – Home devices are less powerful than professional machines, require more frequent use, and may not deliver the same long-term results.
- Potential for Burns – Without professional guidance, users may set the device too high, leading to burns or irritation.
- Not Suitable for All Skin Types – Many at-home lasers work poorly on darker skin tones or very light hair.
While home devices can be convenient for touch-ups, professional treatments remain the safest and most effective option.
Laser Hair Removal Safety for Sensitive Skin
How to Minimise Irritation for Sensitive Skin
Extra care is required to prevent irritation or adverse reactions if you have sensitive skin. Here are some steps to ensure a safe experience:
- Choose the Right Laser – Certain lasers, such as the Alexandrite or Diode, are gentler on sensitive skin.
- Use Soothing Products – Aloe vera and fragrance-free moisturisers can help calm the skin post-treatment.
- Avoid Harsh Skincare Products – Refrain from using exfoliants, acids, or retinoids before and after treatments.
- Stay Out of the Sun – Sun exposure can make the skin more prone to burns and hyperpigmentation.
- Wear Loose Clothing – Tight clothing can cause friction and increase irritation on treated areas.
Consulting with a specialist ensures the right precautions are taken to protect sensitive skin.
