Kkeut Oriental Medicine Clinic's Approach to Erbium YAG Fractional Laser Treatment

Difference in using Erbium YAG instead of CO2:

CO2 lasers penetrate deep into the skin, but carry a relatively high risk of severe thermal damage and hyperpigmentation.

Erbium YAG is used as a fractional laser device that reduces thermal damage while precisely reaching from the epidermis to the dermal-epidermal junction.

Customized Parameter Adjustment:

We meticulously analyze each individual's skin condition to adjust the depth and intensity of the laser.

By applying multiple low-power shots to thin skin and a single high-power shot to thicker skin, for example, we meticulously fine-tune the treatment to reduce the burden on your skin.

Utilization of Overlap Technique:

Considering the specific characteristics of areas with fine lines, scars, or pores, we carefully adjust the treatment intensity by applying multiple overlapping shots.

Fine lines on the back of the hands or neck due to aging can also be treated. These areas are typically challenging, but we proceed with customized settings, carefully considering the skin's regeneration rate and sebaceous gland density.

Fractional Synergy through Skin Booster Delivery Technique:

The micro-channels formed in the skin immediately after fractional laser treatment create an environment favorable for the absorption of active ingredients.

At Kkeut Oriental Medicine Clinic, we apply skin boosters immediately after fractional laser treatment, utilizing a protocol that helps effectively deliver necessary ingredients to the dermal layer.

Considering deep scars and varying skin thickness in different areas, we adjust the degree and intensity of overlapping shots, focusing on opening a path for ingredient absorption up to the dermal-epidermal junction.

When using small-particle skin boosters like PDRN or Juvelook together, they can be absorbed deep into the dermal layer, positively influencing the regenerative process. This can lead to synergistic improvements in pores, fine lines, and acne scars.

What is Fractional Laser?

Fractional laser is named after 'fractional,' meaning 'partial.' Instead of stimulating the entire skin, it's a treatment method that partially irradiates the skin with a laser at very fine intervals.

It creates microscopic holes in the skin, and through this stimulation, it induces the skin's natural regeneration response.

This selective damage-inducing approach has the advantage of reducing recovery burden while leading to overall skin improvement effects.

Ablative Fractional and Non-Ablative Fractional Lasers

Ablative fractional lasers microscopically remove the epidermis and deliver energy to the dermal junction, helping to improve skin texture, wrinkles, and pigmentation. A recovery period may be necessary after treatment.

Non-ablative fractional lasers preserve the epidermis while delivering thermal stimulation to the dermis. Recovery is faster, but the scope of effect may be somewhat limited compared to ablative types.

The Erbium YAG fractional laser used at Kkeut Oriental Medicine Clinic belongs to the ablative laser category.

Principle of Erbium YAG Fractional Laser

Erbium YAG fractional laser belongs to the ablative laser family, specifically using a 2940nm wavelength that reacts to water.

This wavelength can precisely vaporize and remove tissue from the epidermis to the dermal junction. This results in characteristics such as precise depth control, minimal thermal damage, and relatively fast recovery.

Since it removes tissue by reacting with water without burning surrounding tissues, it reduces the risk of hyperpigmentation and lessens the burden of the procedure.

Comparison of DOE and MLA Methods

Fractional laser energy delivery methods are broadly divided into DOE and MLA methods. The DOE (Diffractive Optical Element) method delivers uniform energy to all treatment points, allowing for even energy distribution. However, due to power limitations, the operator's skill is crucial for scar treatment.

In contrast, the MLA (Microlens Array) method has stronger energy at the center of the shot and weaker energy towards the periphery. This can be useful for treating deep scars, but if energy is concentrated in a specific area, recovery may take longer.

Expected Effects of Erbium YAG Fractional Laser Treatment

Kkeut Oriental Medicine Clinic's Erbium YAG fractional laser utilizes the DOE method for energy delivery.

By delivering even energy across the entire skin, the treatment can be performed with reduced burden.

This method can lead to positive effects on pores, fine lines, and skin texture, and in cases like acne scars, improvement can be expected by applying the overlap technique.

Collagen·Elastin Regeneration: It removes damaged skin tissue and stimulates fibroblasts in the dermal layer, contributing to thicker and firmer skin. Improved skin texture and elasticity are expected.

Pore Reduction Effect: The fibrous tissue around the pores is restructured, which can lead to a reduction in pore size and a smoother skin surface.

Acne Scar Remodeling: Old scar tissue gradually breaks down and is replaced by new collagen tissue, leading to a gradual improvement in skin texture.

Erbium YAG Fractional Laser Research Data

Serdar ZA et al. Dermatol Ther. 2019:

333 patients with facial and neck wrinkles

When Er-YAG Fraxel treatment is performed 3 to 4 times, improvement in skin texture, wrinkles, and pigmentation issues can be expected.

Robati RM et al. J Cosmet Dermatol. 2020 Study Results:

It can be recommended to those who wish to manage enlarged pores or fine wrinkles on their face.

Even with a single treatment, changes in fine wrinkles may appear.

If you receive more than 3 treatments, the effect can be maintained longer, and you may observe a tendency for pores to shrink.

A Message from the Chief Director

We treat various skin types every day. We know that no two skin types are the same, and even for the same person, skin condition can vary day by day.

Fraxel treatment is not simply determined by the equipment alone. Considering the patient's skin condition on the day of treatment, we meticulously adjust the laser's output and depth in 0.1 increments.

With this mindset, we approach every treatment moment. We strive to provide more precise and safer treatments to our patients.

We believe that the true completion of a Fraxel treatment goes beyond the equipment itself and is achieved through the skilled hands of our medical staff.

We will do our best to provide satisfactory results to those who trust us and visit our clinic.

Post-Treatment Precautions

• 
  
• 
  
• ㆍIt is recommended not to wash your face or apply makeup on the day of the procedure; light cleansing is advised from the next day.
• 
  
• 
  
• 
  
• ㆍTip marks, redness, and mild pain in the treated area may persist for about 7 days. Cooling care using ice packs can be helpful during this time.
• 
  
• 
  
• 
  
• ㆍFraxel is a type of laser resurfacing treatment, so it is best not to peel off any dead skin cells that appear around 3-4 days after the procedure, but rather let them shed naturally.
• 
  
• 
  
• 
  
• ㆍUntil all dead skin cells have naturally fallen off, it is recommended to avoid alcohol, smoking, saunas, public baths, and swimming pools.
• 
  
• 
  
• 
  
• ㆍThe period immediately after treatment and for about 1-2 weeks after exfoliation is when skin regeneration is active. During this time, it is good to consistently apply a regenerative ointment.
• 
  
• 
  
• 
  
• ㆍPay special attention to moisturizing for skin soothing, and it is crucial to diligently apply sunscreen when going outdoors.
