Guide to Diode Laser Hair Removal at SKNN Clinic
If you are tired of shaving, waxing, plucking, or dealing with ingrown hairs, laser hair removal offers one of the most effective long-term solutions available.
Using advanced diode laser technology, unwanted facial and body hair can be progressively reduced - helping you enjoy smoother skin, less maintenance, and greater confidence in your day-to-day life.
SKNN Clinic Bangkok is pleased to introduce laser hair removal as a new service, using a professional-grade diode laser platform. Located in Sukhumvit Soi 22 - conveniently between BTS Asoke and BTS Phrom Phong - our clinic offers diode laser hair removal treatments for both men and women across a wide range of facial and body areas.
Whether you are considering underarm laser hair removal, Brazilian laser hair removal, facial hair removal, or full-body treatments, this guide covers everything you need to know before getting started.
Laser hair removal at SKNN Clinic Bangkok starts from ฿800 per session. We offer 6-session and 12-session packages across all treatment areas.
What Is Laser Hair Removal?
Laser hair removal is a treatment that uses concentrated light energy to target hair follicles beneath the skin.
The laser is attracted to melanin - the pigment found within the hair shaft. When the light energy is absorbed, it heats the follicle and disrupts its ability to produce future hair growth. Over a course of treatments, most clients experience a significant and lasting reduction in hair growth, with any remaining hair often becoming finer, softer, and less noticeable.
Unlike shaving, which only removes hair at the skin's surface, laser hair removal targets the source of hair growth itself.
Important note on results: Laser hair removal is clinically described as long-term hair reduction, not permanent removal. Most clients achieve an 80-90% reduction in hair growth after a full course of treatment. Some individuals may benefit from occasional maintenance sessions over time, depending on hormonal changes and individual hair growth patterns. This is the standard clinical consensus and applies across all professional laser systems.
The Technology Behind Our Laser Hair Removal
SKNN Clinic Bangkok uses a premium professional diode laser system featuring 4-wavelength technology, an advanced cooling plate, and dual-certified safety clearance from both the US FDA and Thai FDA (TFDA). Here is what that means for you as a patient.
4-Wavelength Technology: Built for Every Skin and Hair Type
Most laser hair removal machines operate on a single wavelength, which means they are optimised for a narrower range of skin tones and hair types. Our system uses four wavelengths simultaneously - 755nm, 808nm, 940nm, and 1064nm - allowing it to be precisely calibrated to your individual combination of skin tone and hair characteristics.
In practical terms, this means:
• 755nm - most effective for finer hair on fairer skin
• 808nm - the standard clinical workhorse, effective across a broad range of skin and hair types
• 940nm - better suited to clients with tanned skin
• 1064nm - designed for coarser hair on darker skin tones, including Fitzpatrick Types V and VI
For clients in Bangkok, where skin tones span a wide range, this multi-wavelength capability matters. It means a single platform can be appropriately adjusted for Thai, Southeast Asian, South Asian, and other skin tones rather than applying a one-size-fits-all approach.
FDA-Certified Safety
Our device carries clearance from both the US FDA and the Thai FDA (TFDA). These certifications confirm that the device meets internationally recognised safety and efficacy standards for professional laser hair removal. You can book with confidence that the technology used at SKNN Clinic is not a grey-market or uncertified device.
Built-In Cooling for Comfort
The system incorporates an advanced cooling plate that maintains the handpiece at a controlled temperature throughout your treatment. This active cooling is designed to protect the surface of your skin and significantly reduce discomfort during the session - particularly relevant for sensitive treatment areas.
Precision Across All Treatment Areas
Different areas of the face and body require different levels of precision. Our system includes multiple interchangeable treatment tips - from larger applicators suited to broad areas like the back and legs, down to smaller precision tips for delicate areas such as the upper lip or hairline. This means every area can be treated with the appropriate level of accuracy rather than a single fixed setting.
Is Diode Laser Suitable for Asian and Thai Skin Tones?
This is one of the most relevant questions for clients in Bangkok, and it deserves a direct answer.
Skin tone is classified using the Fitzpatrick scale, which ranges from Type I (very fair) to Type VI (very deep). Most Thai and Southeast Asian skin falls within Fitzpatrick Types III to V.
Most single-wavelength laser systems are optimised for a specific range of skin tones, which can limit their suitability for the full diversity of skin types seen across Thailand and Southeast Asia. The 4-wavelength system used at SKNN Clinic is specifically designed to cover the full Fitzpatrick spectrum - from fair skin at 755nm through to darker skin tones at 1064nm - meaning it can be calibrated appropriately for a much wider range of patients than a single-wavelength device.
At SKNN Clinic, every client begins with a personalised assessment to confirm suitability and determine the correct parameters for their individual skin tone and hair characteristics.
One important caveat applies to all laser hair removal systems: clients with very light, fine, blonde, red, or grey hair will see more limited results, as these hair colours contain less melanin for the laser to target. This is not unique to our system - it is a fundamental characteristic of how laser hair removal works. If this applies to you, we will discuss realistic expectations honestly during your consultation.
Why Are People Choosing Laser Hair Removal?
Most people begin laser hair removal for convenience. What starts as frustration with shaving or waxing often becomes a decision that saves considerable time and cost in the long run.
Time Saving
Many people shave several times per week to maintain smooth skin. A full course of laser hair removal can dramatically reduce this ongoing maintenance, freeing up time over the months and years that follow.
Fewer Ingrown Hairs
Ingrown hairs are a common concern - particularly in the underarm, bikini, Brazilian, beard, and neck areas. By progressively reducing active hair follicles, laser hair removal often leads to a significant reduction in ingrown hairs, which also helps improve the appearance of skin texture in those areas.
Long-Term Cost Comparison
The upfront cost of a laser hair removal course may be higher than a single waxing appointment, but when compared against years of waxing visits or the lifetime cost of razors and shaving products, many clients find laser hair removal to be the more economical choice over time.
Smoother Skin Texture
Without the cycle of shaving and regrowth, many clients report noticeably smoother-feeling skin and reduced irritation, particularly in sensitive areas.
How Does Laser Hair Removal Work?
To understand why multiple sessions are needed, it helps to understand how hair grows.
The Hair Growth Cycle
Hair grows in three main phases:
Anagen - Active Growth Phase: this is when the hair is actively connected to the follicle and contains the highest concentration of melanin. Laser hair removal is most effective during this stage, as the laser energy can be efficiently absorbed and transmitted to the follicle.
Catagen - Transition Phase: the hair begins detaching from the follicle. Laser treatment is less effective at this stage.
Telogen - Resting Phase: the hair is dormant and will eventually shed before a new hair begins growing. Laser treatment has minimal effect during this phase.
Because not all hairs in any given area are in the same phase at the same time, a single treatment cannot reach every active follicle.
This is why a course of multiple sessions - spaced at appropriate intervals - is necessary to progressively treat the area as follicles cycle through their active growth phase.
How Many Sessions Will I Need?
The number of sessions required varies from person to person and depends on several factors:
Treatment area - some areas respond faster than others; underarms and lower legs often show early results
Hair thickness and density - coarser, denser hair typically requires more sessions
Hair colour - darker hair contains more melanin and generally responds well; lighter hair colours absorb less laser energy and may require additional sessions
Skin tone - treatment parameters are adjusted based on individual skin characteristics
Hormonal factors - hormonal changes, including those related to PCOS, pregnancy, or menopause, can affect hair growth patterns and treatment outcomes
Genetics - individual hair growth patterns varies
Most clients require between 6 and 12 sessions to achieve optimal long-term hair reduction, scheduled at intervals of approximately 4 to 8 weeks depending on the treatment area. Some clients may benefit from occasional maintenance sessions after completing their initial course.
We will discuss realistic expectations for your specific case during your appointment.
What Areas Can Be Treated?
Laser hair removal can be performed on many areas of the face and body.
Facial Areas: Upper lip, chin, full face, beard shaping, sideburns, nose area
Body Areas: Underarms, bikini line, Brazilian, arms, forearms, hands, legs, lower legs, back, shoulders, chest, abdomen
Both men and women can benefit from laser hair removal treatments across all of these areas.
Laser Hair Removal for Women
Some of the most popular treatment areas for women at SKNN Clinic include underarms, bikini line, Brazilian, legs, upper lip, and chin.
Many women choose laser hair removal to simplify their daily routine, reduce the need for frequent waxing or shaving, and address concerns such as ingrown hairs or skin irritation in sensitive areas.
Laser Hair Removal for Men
Laser hair removal is increasingly sought by men in Bangkok. Common treatment areas include beard shaping and neck definition, back, shoulders, chest, and arms.
Many male clients seek treatment to reduce irritation from daily shaving, minimise persistent ingrown hairs on the neck and jawline, or reduce unwanted body hair for cosmetic or comfort reasons.
Before and After Your Treatment: What to Know
Before Treatment
Shave the area 24 hours before your appointment - shaving is recommended prior to treatment
Do not wax, pluck, or use depilatory creams in the weeks before treatment; these methods remove the hair root that the laser needs to target
Avoid significant sun exposure to the treatment area in the weeks before your session, and inform your therapist if you are tanned
Avoid retinoids and certain topical treatments in the days before treatment - your therapist will advise based on your skincare routine
After Treatment
Mild redness or warmth in the treated area is normal and typically resolves within a few hours
Avoid direct sun exposure to treated areas immediately after treatment; apply SPF 50 sunscreen when outdoors - this is particularly important in Bangkok's climate
Avoid heat (hot showers, saunas, intense exercise) for 24-48 hours after treatment
Do not wax or pluck between sessions; shaving is fine if needed
Diode Laser vs. IPL: What Is the Difference
These two technologies are often grouped together, but they are meaningfully different.
Diode laser uses a focused, single wavelength of light specifically designed to target hair follicles. The precision of the wavelength allows for more targeted energy delivery to the follicle.
IPL (Intense Pulsed Light) uses a broader spectrum of light wavelengths. While IPL can be effective for hair removal, it is a broader-spectrum technology and is considered less targeted than a dedicated laser system.
Diode laser systems are widely used in professional clinical settings for hair removal and are a standard technology in medical aesthetic clinics globally.

Frequently Asked Questions
Is laser hair removal worth it?
For most clients, yes. The combination of reduced grooming time, fewer ingrown hairs, and smoother skin over the long term makes laser hair removal a worthwhile investment compared to the ongoing cost and effort of shaving and waxing. Results vary between individuals, which is why we recommend a consultation to discuss realistic expectations for your specific case before committing to a course of treatment.
Is laser hair removal permanent?
Laser hair removal is clinically classified as long-term hair reduction, not permanent removal. Most clients achieve an 80-90% reduction in hair growth after completing a full course. Some individuals - particularly those with hormonal influences on hair growth - may benefit from occasional maintenance sessions over time. This is true of all professional laser hair removal systems, regardless of technology.
How many sessions do I need?
Most clients require between 6 and 12 sessions, scheduled approximately 4 to 8 weeks apart. Individual requirements vary based on the treatment area, hair characteristics, skin tone, and hormonal factors. Your therapist will give you a more specific estimate during your consultation.
Does laser hair removal hurt?
Most clients find it significantly more comfortable than expected. The sensation is commonly described as a brief, warm snap against the skin. Sensitivity varies by treatment area - bony areas and sensitive zones may feel more noticeable - but the majority of clients tolerate treatment well. Modern diode laser systems incorporate cooling technology specifically to maximise comfort.
Why do I need to shave but not wax before laser hair removal treatment?
Shaving removes hair above the skin surface while leaving the follicle and hair root intact beneath the skin. Waxing, plucking, and epilating remove the hair from the follicle entirely. Since the laser needs pigment within the follicle to effectively target and heat it, removing the hair root reduces treatment effectiveness. Shaving before your appointment is recommended; waxing should be avoided throughout your treatment course.
Is diode laser suitable for Asian and Thai skin tones?
Diode laser systems are among the most commonly used technologies for Fitzpatrick Types III-V skin - the range that covers most Thai and Southeast Asian skin tones. Suitability and treatment parameters are assessed individually at consultation. Clients with very fair hair or very dark skin tones should discuss their specific case with the team to ensure appropriate expectations.
Can laser hair removal help with ingrown hairs?
Yes. Many clients seek laser hair removal specifically because of recurring ingrown hairs. By progressively reducing active hair follicles, laser treatment reduces the conditions that lead to ingrown hairs forming, particularly in areas like the underarms, bikini line, neck, and beard area.
Can laser hair removal help with strawberry legs?
Many clients notice an improvement in the appearance of strawberry legs - the dark pore-like dots on the legs - as hair follicle activity reduces. This is a secondary benefit rather than the primary purpose of the treatment, but it is a commonly reported improvement.
How long does a session take?
Treatment times depend on the area being treated. Small areas such as the upper lip may take just a few minutes. Larger areas such as the legs or back require more time. Your therapist will advise on expected treatment duration for your chosen area at your consultation.
What happens if I miss a session?
Missing a session does not undo progress from previous treatments. However, maintaining a consistent treatment schedule is important for optimal results, as the intervals are designed to align with the hair growth cycle. If you need to reschedule, contact the clinic as early as possible.
Can I exercise after treatment?
Most clients can return to normal activities immediately after treatment. However, it is generally recommended to avoid intense exercise, heat, and sweat for 24-48 hours following a session, as these can cause irritation to the treated skin.
Can I go in the sun after treatment?
Excessive sun exposure to treated areas should be avoided immediately following treatment. Sunscreen - SPF 50 or higher - should be applied whenever going outdoors. This is especially relevant in Bangkok, where UV exposure is consistently high throughout the year.
Can I have laser hair removal before a holiday?
Yes, though timing should be planned carefully. Avoid scheduling a session immediately before significant sun exposure, and discuss your travel plans with your therapist so treatment timing can be adjusted appropriately.
