What are the characteristics of Erbium YAG Fractional Laser?

Utilizes Erbium YAG laser instead of CO2 laser:

While CO2 lasers penetrate deep into the skin, they can cause significant thermal damage to surrounding tissues and carry a relatively higher risk of hyperpigmentation.

Erbium YAG is a fractional laser device that precisely delivers energy from the epidermis to the dermal-epidermal junction while minimizing thermal damage.

Customized parameter adjustment according to skin condition:

The treatment depth and intensity are carefully adjusted, taking into account each individual's skin characteristics.

The procedure involves delicate adjustments, such as applying low power multiple times to areas with thin skin and using high power once for thicker areas.

Application of Overlap Technique:

For specific skin concerns like fine lines, scars, and pores, the laser can be applied repeatedly to finely adjust the treatment intensity.

Treatment can also be considered for areas with fine lines due to aging, such as the back of the hands or neck. Even for areas typically challenging to treat, customized settings can be used, taking into account skin regeneration speed and sebaceous gland density.

Enhancing Fractional Laser Treatment Effects through Skin Booster Delivery Technique:

The microscopic channels created in the skin immediately after fractional laser treatment can be utilized.

Immediately after fractional laser treatment, a skin booster application protocol is followed to help effectively deliver active ingredients to the dermal layer.

Considering deep scars or varying skin thickness in different areas, the degree of overlap and intensity are adjusted to create microscopic channels down to the dermal-epidermal junction.

When small-particle skin boosters like PDRN or Juvelook are used in conjunction, active ingredients can be deeply absorbed into the dermal layer, which is crucial for regeneration. This can lead to positive improvements in pores, fine lines, and acne scars.

What is Fractional Laser?

Fractional laser is a term derived from 'fractional,' referring to a treatment method that delivers energy only partially, with microscopic gaps, instead of irradiating the entire skin surface.

It works by creating microscopic channels in the skin, and this stimulation promotes the skin's natural regeneration process.

This method, which induces partial damage, can help reduce recovery burden while still expecting overall skin improvement effects.

Ablative vs. Non-Ablative Fractional Laser

Ablative Fractional Laser: It finely removes the epidermal layer and delivers energy to the dermal-epidermal junction, aiding in the improvement of skin texture, wrinkles, and hyperpigmentation. A certain period of recovery may be required after the procedure.

Non-Ablative Fractional Laser: This method preserves the epidermis while delivering thermal energy to the dermal layer. The recovery period is relatively short, but the range of expected improvement effects may be somewhat more limited compared to ablative lasers.

The Erbium YAG fractional laser used at our clinic is an ablative laser.

Principle of Erbium YAG Fractional Laser Action

Erbium YAG fractional laser is a type of ablative laser that uses a 2940nm wavelength, which selectively reacts with water in the skin.

This wavelength precisely vaporizes tissue from the epidermis to the dermal-epidermal junction, which can contribute to increasing the accuracy of treatment depth control, reducing thermal damage to surrounding tissues, and decreasing recovery burden.

Since this method removes tissue by delivering energy through the water within the tissue without excessively burning surrounding areas, it can reduce the possibility of hyperpigmentation.

Comparison of DOE vs. MLA Methods

When performing fractional laser treatment, the energy delivery methods are broadly categorized into DOE (Diffractive Optical Element) and MLA (Microlens Array) methods. The DOE method delivers uniform energy to all treatment points, dispersing energy evenly. However, it may have power limitations, so the expertise of the medical staff is crucial for scar treatment.

The MLA method concentrates strong energy on the central area and delivers weaker energy to the surrounding areas. This can be advantageous for treating deep scars, but it's important to consider that an excessive concentration of energy in specific areas may prolong the recovery period.

Effects of Erbium YAG Fractional Laser

The Erbium YAG fractional laser at our clinic delivers energy using the DOE method,

which focuses on delivering energy uniformly across the entire skin.

This method may be more suitable for improving pores, fine lines, and skin texture, and even for conditions like acne scars, improvement effects can be expected using the overlap technique.

Collagen & Elastin Regeneration: It tidies damaged skin tissue and stimulates fibroblasts in the dermal layer to induce collagen and elastin production. This allows the skin to regenerate more densely and can contribute to enhanced elasticity.

Pore Reduction: As the collagen fibrous tissue around pores is reorganized, it helps in pore contraction, which can lead to a smoother skin surface.

Acne Scar Improvement: Existing scar tissue is gradually broken down and replaced with new collagen tissue, leading to an overall improvement in skin texture.

There have been cases where 3-4 sessions of Er:YAG Fraxel treatment resulted in visible improvements in skin texture, wrinkles, and areas of hyperpigmentation.

Robati RM et al. J Cosmet Dermatol. 2020:

This treatment may be suitable for those looking for overall skin improvement through the reduction of facial pores and fine wrinkles.

Improvements in fine wrinkles can be observed even after a single session.

After 3 or more sessions, the improved condition can be maintained long-term, and you may also experience pore tightening.

A Message from the Director

Encountering various skin types daily, I recognize that every individual's skin is unique, and even for the same person, its condition can change from day to day.
