Understanding Fractional Laser Beams Theories
Fractional laser technology is a groundbreaking advancement in the field of dermatology and cosmetic treatments. It works by using high-intensity laser beams to target specific areas of the skin, promoting rejuvenation and healing. Here's a comprehensive look at how fractional laser beams operate and their applications in both non-ablative and ablative photothermolysis.
How Fractional Laser Beams WorkWhen the high-intensity laser beam hits the skin, it is absorbed by the chromophores (the pigment-containing cells) in the target area. The electromagnetic energy from the laser is then converted into thermal energy, causing a rapid increase in temperature. This thermal effect induces a controlled injury to the skin cells, which triggers the body's natural healing process.
During this process, new Heat Shock Protein 70 (HSP-70) cells are generated around the dermis. These proteins play a crucial role in protecting cells from stress and aiding in the repair of damaged proteins. Additionally, collagen, a vital protein for maintaining skin elasticity and firmness, is formed. The result is the formation of new, healthy skin tissue, which appears smoother, more even, and youthful.
Non-Ablative Fractional Photothermolysis
Non-ablative fractional photothermolysis uses a picosecond laser with a micro spot size and short pulse width. This type of laser is highly effective for treating various skin concerns without causing significant damage to the surface of the skin. The picosecond laser delivers energy in ultra-short pulses, which minimizes the risk of side effects and allows for quicker recovery times.
- Effective Treatment: Non-ablative lasers are ideal for addressing pigmentation issues, fine lines, and mild to moderate skin laxity. They work by creating micro-injuries beneath the skin's surface, stimulating collagen production and promoting cell turnover.
- Minimal Downtime: Since the outer layer of the skin is left intact, patients can return to their normal activities almost immediately after treatment.
- Targeted Results: The precision of the micro spot size allows for targeted treatment of specific problem areas, resulting in more uniform and natural-looking results.
Ablative Fractional Photothermolysis
Ablative fractional photothermolysis involves the use of CO2 and Er lasers. These lasers remove the outer layers of the skin to a greater extent than non-ablative lasers, making them suitable for more severe skin issues.
- CO2 Laser: Known for its efficacy in resurfacing the skin, the CO2 laser is highly effective in treating deep wrinkles, severe sun damage, and prominent scars. It works by vaporizing the damaged skin cells, promoting the regeneration of new skin.
- Er Laser: The Er laser is used for more precise ablation, making it suitable for delicate areas and finer lines. It offers controlled penetration, reducing the risk of thermal damage to surrounding tissues.
Dramatic Results: Ablative lasers produce more noticeable improvements in skin texture and tone. They are particularly effective for patients with significant photoaging and deep scars.
Longer Downtime: Due to the removal of the outer skin layers, patients may experience a longer recovery period, which includes redness, swelling, and peeling.

Characteristics of Depth of Focus and Small Spot Size in Dermatology
Understanding Depth of Focus and Small Spot SizeIn the field of dermatology, the precision and efficacy of laser treatments are significantly influenced by the depth of focus (DOF) and the size of the laser spot. These characteristics are critical for achieving optimal results in skin treatments, ensuring both effectiveness and safety.
Long Depth of Focus (DOF)
The depth of focus refers to the distance over which the laser beam maintains a tight focus. A long DOF is particularly advantageous in dermatological applications for several reasons:
Consistency on Curved Surfaces: The human skin is not a flat surface; it has curves and contours. A long DOF ensures that the laser maintains a small, precise spot size even on these uneven surfaces. This is crucial for treating areas like the face, neck, and other curved regions effectively.
Enhanced Precision: With a long DOF, dermatologists can deliver laser energy accurately to the targeted area, minimizing the risk of unintended damage to surrounding tissues.
Small Spot Size
The spot size of a laser is another vital factor in dermatology. A small spot size offers several benefits:
High Energy Intensity: Smaller spot sizes allow the laser to concentrate its energy more intensely on a specific area. This high energy intensity is essential for targeting deep layers of the skin, such as the dermal layer, without affecting the superficial layers.
Controlled Thermal Damage: The ability to deliver high-intensity energy to the dermal layer with a small spot size means that treatments can be more effective while reducing thermal damage to the skin. This leads to quicker recovery times and less discomfort for patients.
Precision in Treatment: Small spot sizes enable dermatologists to treat very specific areas with great accuracy. This is especially important for procedures like removing pigmented lesions, treating fine lines, and performing intricate skin resurfacing.
Advantages in Dermatological Treatments
The combination of a long depth of focus and a small spot size offers several advantages in dermatological treatments:
Effective Targeting: The laser can effectively target specific areas, ensuring that the treatment is concentrated where it is needed most. This is particularly beneficial for treating conditions like acne scars, wrinkles, and pigmentation issues.
Minimized Side Effects: By focusing the energy precisely and minimizing the thermal spread, the risk of side effects such as redness, swelling, and scarring is significantly reduced.
Improved Patient Comfort: Patients experience less discomfort and downtime due to the controlled application of laser energy. The precision of the treatment allows for quicker healing and better overall results.
Conclusion
In dermatology, the characteristics of depth of focus and small spot size play a pivotal role in the success of laser treatments. At SEA HEART GROUP, we leverage advanced laser technologies to ensure our devices offer these critical features, providing dermatologists with the tools they need to deliver exceptional results.

Revolutionizing Dermatology with Picosecond Lasers
The advent of picosecond lasers has brought about a significant shift in dermatological treatments, particularly with the 300ps Nd
picosecond laser. This cutting-edge technology leverages ultra-high peak power to introduce new, non-ablative skin rejuvenation techniques that offer remarkable results without the drawbacks of traditional methods.
The Plasma Effect in Picosecond Lasers
One of the key innovations in picosecond laser technology is the plasma effect. When the ultra-high peak power of the 300ps Nd
laser is applied to the skin, it induces a plasma effect characterized by a rapid acceleration of electrons. This plasma effect triggers an inertial reaction within the skin, creating micro injuries that promote the body's natural healing processes.
Benefits of the Plasma EffectNon-Ablative Skin Rejuvenation: Unlike traditional ablative lasers that remove layers of skin, the picosecond laser with its plasma effect allows for non-ablative treatments. This means that the surface of the skin remains intact while the laser works beneath the dermis to stimulate collagen production and rejuvenate the skin.
Enhanced Precision: The 300ps pulse duration ensures that the laser energy is delivered in ultra-short bursts, minimizing the risk of thermal damage to the surrounding tissues. This precision makes it possible to target specific skin concerns without affecting the overall skin integrity.
