My Personal Test! Which Permanent Laser Hair Removal Really Works? Side Effects + Difference Between 1064nm, 810nm, and 755nm

For most women, hair removal is a summer must-do. More and more women are choosing full-body permanent hair removal — after all, bikinis, mini skirts, and shorts reveal more skin, and visible hair can ruin the look in an instant.

But with so many hair removal methods out there, do you know the pros and cons of each? And which one can actually deliver permanent results? Let’s break it down.

Why Go for Permanent Hair Removal? The Benefits You Didn’t Know

Sure, body hair serves a purpose — protecting the skin and regulating temperature — but for many modern women, smooth skin just feels better. And the benefits go beyond aesthetics:

1. Stay Clean and Fresh

Removing hair gives a neat, fresh appearance and helps reduce stuffiness during hot weather. Summer outfits like tank tops and shorts often expose the skin, and stray hairs can be… awkward.

2. Reduce Body Odor

Too much hair traps sweat and bacteria, which can lead to acne, eczema, allergies, or even skin infections. Sweat mixing with oil and bacteria can also cause strong body odor — including underarm odor — so removing hair can help keep you smelling fresh.

3. Smoother Makeup Application

Facial hair can prevent foundation from sitting evenly, leading to patchy or cakey makeup. Permanent hair removal not only removes hair but can also help get rid of dead skin cells and excess oil, leaving your skin smoother and makeup-ready.

4. Improve Intimate Confidence

Keeping the bikini area smooth can boost confidence, enhance intimacy, and make swimsuits look even better.

Comparing Permanent Hair Removal Methods

1. Waxing

Waxing pulls hair out from the root, making it last longer than shaving — usually about a week before fine regrowth appears. But it’s painful and not permanent.

2. At-Home Laser Devices

Cheaper than salon treatments and convenient, but home devices are less powerful, and technique affects results.

3. IPL (Intense Pulsed Light)

Once the most popular method before laser technology took over. It weakens hair over time but requires 10–20 sessions for noticeable results. Bonus: it can also help with skin brightening and pore refinement.

4. Professional Laser Hair Removal

The most effective and truly permanent option. Concentrated laser energy targets hair follicles to stop growth. Usually, just 6 sessions are enough for lasting results.

3 Common Questions About Permanent Laser Hair Removal

1. How many sessions are needed?

Generally 6–8 treatments remove up to 90% of hair permanently, but results vary depending on the machine, operator, and your hair growth cycle.

2. Are there side effects?

Some temporary redness or swelling is normal and fades within hours. Inexperienced operators or too-high settings can cause burns or peeling.

3. Does it hurt?

Laser is high-energy, so you might feel some heat or discomfort. Cooling gel, ice packs, and devices with built-in cooling help make it tolerable and safe.

Laser Wavelengths Explained: 755nm, 808/810nm, and 1064nm

Different wavelengths target different hair and skin types:

• 755nm – Best for thick, coarse dark hair.
• 808/810nm – Great for medium to dark brown hair.
• 1064nm – Ideal for fine, light hair.

Using the right wavelength for your skin tone and hair type maximizes results and safety.

Things to Keep in Mind Before and After Permanent Hair Removal

So, you’ve decided to go for laser hair removal — great choice! But how can you make sure your treatment goes as smoothly as possible? Here are a few things worth paying extra attention to.

1. Trim Hair to the Right Length

Many people assume the beautician will shave the area before the session, so there’s no need to prepare. But trimming beforehand not only saves time during the appointment, it also helps the laser work more effectively. Aim to trim hair down to about 1mm the day before your treatment.

2. Check Your Medications

Certain medications — such as antibiotics or aspirin — can make your skin more sensitive to light, increasing the risk of burns or irritation. If you’re on long-term medication, consult your doctor before booking a laser session.

3. Avoid Sun Exposure

For at least 4 weeks before and after your treatment, avoid tanning or prolonged sun exposure. Always wear SPF 30+ when going outdoors to protect the treated skin, which will be more delicate. Sun exposure can also increase melanin production, leading to pigmentation.

4. Skip Intense Heat and Workouts

Laser hair removal is a high-energy treatment that leaves the skin slightly heated. Strenuous exercise or hot environments can cause redness, discomfort, or even rashes in the treated area. Take it easy for at least one week after treatment.

5. Moisturise Well

Your skin may feel drier after treatment. Apply fragrance-free, gentle moisturisers to soothe and hydrate the skin, helping it recover faster.

6. Stop Using Whitening or Acidic Skincare

Before and after your treatment, avoid whitening products or anything with acids (like AHA/BHA). These thin the skin’s outer layer, making it more prone to irritation.

Recently, I tried the Perfect Medical A3 Laser Hair Removal Treatment to see if it lived up to the hype. First, the tech:

The treatment room was spotless, the therapist experienced and gentle, and the whole session took just 5 minutes. Each laser pulse was preceded by a cool sensation — I barely felt any heat at all.

Within two hours, any redness was gone. Two weeks later, the regrowth was soft, fine, and almost invisible. After completing five sessions at the recommended intervals, my underarm hair was completely gone. Smooth, precise, and super quick — I couldn’t be happier.
