Laser Hair Reduction Explained by a Dermatologist: Upper Lip, Underarms & Bikini Area

We all love smooth, hair-free skin — but achieving it can be a constant struggle. Waxing, threading, shaving, or tweezing — most of us have tried them all. These methods can be painful, messy, and worst of all, temporary.

If you’re done with endless shaving or waxing, Laser Hair Reduction (LHR) provides a lasting, low-maintenance way to stay smooth. We use advanced medical-grade laser technology that helps you enjoy smoother skin for longer.

What Is Laser Hair Reduction?

Laser Hair Reduction (LHR) is a safe dermatological treatment that uses focused laser beams to eliminate unwanted hair. The laser light targets melanin in the hair, converting it into heat that weakens hair follicles without affecting nearby skin.

Because it works on the pigment, the treatment is most effective on darker, thicker hair, which absorbs more laser energy. With multiple sessions, the hair that does grow back is finer, lighter, and sparser — often to the point where it’s barely visible.

How Laser Hair Reduction Works – The Science Behind It

Each hair on our body grows in cycles:

1. Anagen Phase (Active Growth): Hair is growing and attached to the follicle — the only stage when the laser can effectively destroy it.

2. Catagen Phase (Transition): Growth stops, and the hair detaches from its follicle.

3. Telogen Phase (Resting): Old hair sheds, and new growth starts.

Since all hairs aren’t in the same stage, several sessions are needed to catch each hair in the active (anagen) phase.

Common Treatment Areas and How Laser Hair Reduction Is Done

Let’s now focus on how LHR is performed for the most commonly treated areas — upper lip, underarms, and bikini line. Each area has its own technique and considerations to ensure effective and safe results.

1. Upper Lip Laser Hair Reduction

The upper lip, being a sensitive area, requires careful precision during treatment. Many women resort to threading, waxing, or bleaching — which often leads to darkening, redness, or small bumps. Laser treatment offers a gentler, long-term solution.

How it’s done:

1. The skin is first cleansed to remove impurities.
2. A cooling gel is applied to protect and smooth the laser’s movement.
3. The laser handpiece is used to deliver precise pulses on the upper lip area — this takes only 5–10 minutes.

4. You may feel a mild pricking or warmth, but it’s well-tolerated and comfortable.

5. A cooling lotion or compress is applied afterward.

Results:
Hair becomes finer and lighter with each visit. The upper lip skin looks smoother and lighter without the shadow or darkness caused by frequent hair removal.

2. Underarm Laser Hair Reduction

Underarm hair grows quickly and can cause odor, sweat accumulation, and darkening due to repeated shaving or waxing. Laser Hair Reduction not only eliminates hair but also brightens and smoothens the underarm skin.

How it’s done:

1. The area is clean-shaven before the session so the laser can directly target the hair root.

2. Protective eyewear is worn by both doctor and patient.

3. The Diode laser is passed over the underarm region in short pulses. Thanks to the in-built cooling technology, the treatment stays comfortable. 
4. The session lasts 10–15 minutes per side.

Aftercare:
Avoid deodorant, tight clothes, or hot showers for 1–2 days. Mild redness is normal and subsides quickly.

Results:
With every session, hair density and thickness reduce significantly. The skin becomes smoother, softer, and visibly lighter as dark stubble and pigmentation fade away.

3. Bikini Area Laser Hair Reduction

The bikini or intimate area is a sensitive region where traditional hair removal methods like waxing or shaving often lead to cuts, ingrown hairs, and irritation. Laser treatment here provides clean, hygienic, and long-lasting results.

How it’s done:

1. The area is prepared and cleaned with a gentle antiseptic.

2. The patient is provided with privacy and protective coverings for comfort.

3. A layer of cooling gel is spread evenly, and the laser targets only the hair follicles with high precision.
4. Since this area is sensitive, a low-energy setting is used initially and adjusted over sessions for optimal results.

Procedure time: 15–20 minutes.

Aftercare:

• Avoid tight clothing, friction, and hot baths for 24 hours.

• Apply soothing aloe vera or prescribed creams if mild redness occurs.

Results:
Results: After 6–8 sessions, hair growth reduces noticeably, leaving smooth, clean skin free from irritation, ingrown hairs, and razor burns.
