What Is Laser? Understanding the Benefits of Laser Technology
Many people have probably heard the term “laser” often in the medical and aesthetic fields, but do you know what it actually is?
In fact, laser refers to a special type of light that has unique properties, making it different from the ordinary light we see every day.

What Is Laser?
Laser technology uses concentrated, high-intensity light energy focused on a specific area for both medical and aesthetic purposes.
In dermatology, laser energy is converted into heat, which can precisely remove pigments, abnormal cells, or blood vessels without damaging the surrounding tissue.
How Many Types of Laser Are There?
There are many different types of laser, each with unique properties and applications depending on several factors, such as:
- The medium used to generate light — solid, liquid, gas, or semiconductor.
- The operation mode — continuous wave (CW laser) or pulsed laser, which emits short bursts of light.
- The wavelength — ranging from short to long, determining how deeply the laser penetrates the skin.
In general, lasers can be divided into two main groups:
- Lasers for Skin Treatments. Examples include IPL (Intense Pulsed Light), Q-Switched Laser, Pico Laser, Dual Yellow Laser, and Fractional Lasers such as CO₂ Laser and Erbium YAG Laser. These are commonly used for skin rejuvenation, pigmentation reduction, and pore tightening.
- Lasers for Hair Removal. Common devices include Ruby Laser, Long-Pulsed Alexandrite Laser, Long-Pulse Nd:YAG Laser, and Diode Laser — all of which target hair follicles to permanently reduce unwanted hair growth.
What can laser treatments help with?
Laser technology can address a wide range of medical and aesthetic concerns, such as:
- Medical treatments: Treating varicose veins, removing moles or skin tags, and managing certain skin diseases.
- Dermatology: Improving acne scars, minimizing large pores, reducing wrinkles, treating acne, fading dark spots, and evening out skin tone.
- Hair removal: Eliminating unwanted hair from various areas of the body — including the bikini area, underarms, beard, upper lip, arms, legs, chest, abdomen, and back.
How does laser technology work?
The principle behind laser treatment is the use of high-intensity light energy at a specific wavelength.
When the laser light hits a target — such as pigment in the skin, hair follicles, or blood vessels — the light is absorbed and converted into heat energy. This process precisely destroys or alters the targeted structure without damaging the surrounding tissue.
Advantages of laser treatments
- High precision with targeted results.
- Quick and noticeable improvements with continued sessions.
- Treat multiple skin issues in a single procedure.
- Safe when performed by experienced medical professionals or specialists.
- Minimal to no downtime.
- No incisions or scarring.
Disadvantages of laser treatments
- More expensive than traditional treatment methods.
- May cause temporary redness, peeling, or small scabs (depending on the type of laser).
- Requires multiple sessions to achieve optimal results.
Laser and the skin
Laser technology has revolutionized dermatology — allowing treatments to target specific skin layers effectively:
- Epidermis (outer layer): Helps even out skin tone and reduce dark spots.
- Dermis (middle layer): Stimulates collagen production, reduces wrinkles, tightens skin, and removes hair (as this layer contains hair follicles).
- Subcutaneous layer (deep layer): Helps reduce excess fat deposits.
To make it easier to understand, the next sections will explain facial laser treatments and laser hair removal separately.
Facial Laser Treatment
Facial laser treatment, also known as skin rejuvenation laser, is a method used to improve various skin concerns — such as acne, acne scars, redness, dark spots, melasma, freckles, and uneven skin texture.
Each type of laser emits light at a different wavelength, making it suitable for specific skin conditions. For example, certain lasers are more effective for pigmentation, while others are designed to smooth skin texture or reduce redness.
Laser Hair Removal
Laser hair removal is a popular method for eliminating unwanted hair. The laser light precisely targets the melanin pigment in the hair root and destroys the follicle, causing hair to regrow more slowly, become finer, and eventually stop growing altogether.
This treatment provides long-lasting results compared to shaving or waxing and significantly reduces the risk of side effects such as skin irritation, ingrown hairs, folliculitis, uneven skin texture, wounds, or infection.

Laser Technologies Used at V Square Clinic
Pico Laser
Pico Laser is an advanced laser technology specifically designed to treat pigmentation problems such as melasma, freckles, dark spots, acne marks, acne scars and tattoos. It delivers highly concentrated light energy in picoseconds (one trillionth of a second) — thousands of times faster than the older nanosecond lasers.
When the laser targets pigment in the skin, it breaks the pigment into tiny dust-like particles that are naturally eliminated by the body. Since the energy is released so quickly that it doesn’t accumulate as heat, it reduces the risk of burns, dark spots, or peeling. It also stimulates collagen regeneration, resulting in smoother and brighter skin.
Currently, there are several well-known brands of Pico Lasers, such as PicoSure Pro, Pico Plus, PicoWay, Discovery Pico, and Enlighten.
LED Light Therapy
LED Light Therapy with the Bellalux Lite device is not a laser treatment itself but is often used in combination with laser procedures such as Pico Laser or other rejuvenation lasers. It helps reduce swelling, inflammation, and accelerate wound healing, allowing the skin to recover more quickly.
Many people mistakenly think that LED light devices are a type of laser, but in reality, they use specific wavelengths of LED light to target different skin concerns.
Each light color has its own unique properties:
- Red Light (625 nm): stimulates hair growth.
- Yellow Light (592 nm): boosts collagen production.
- Blue Light (460 nm): kills acne-causing bacteria and reduces acne.
- NIR Light (850 nm): helps fade melasma, freckles, and dark spots.
Microneedling RF
The Microneedling RF technology of Sylfirm X is another breakthrough innovation that targets the Basement Membrane, the origin of issues like melasma, vascular lesions, and stubborn acne scars.
Sylfirm X delivers radiofrequency energy through microneedles with precision, treating melasma, pigmentation, acne scars, enlarged pores, active acne, redness, and dark marks. The RF energy forms microthermal zones deep within the skin, stimulating new collagen formation, repairing damaged tissue, and restoring firmness, smoothness, and skin resilience.
Yag Laser
YAG Laser (Yttrium Aluminum Garnet Laser) is a solid-state laser that uses YAG optical crystal material as the gain medium. The emitted light converts into heat energy at different skin depths, targeting melanin pigments and breaking them down to fade dark spots, redness, freckles, melasma, and tattoos.
Fotona SP Dynamis is one of the most advanced YAG laser systems, combining Er:YAG (2940 nm) and Nd:YAG (1064 nm) wavelengths in a single device to effectively treat multiple skin layers.
In addition, YAG lasers can be used for hair removal — the heat energy weakens the hair root, causing it to shed naturally over time.
At V Square Clinic, the Cool YAG 1064 program uses the Light-B EVO laser from Italy, a Long Pulse Nd:YAG 1064 nm system that penetrates deeply to the hair root. It is suitable for all hair types and skin tones, ensuring effective and safe results.
