Doctor's Column

UltraClear™ is a next-generation fractional laser developed by Acclaro Medical in the US that uses the world's first 2910nm wavelength. It is an innovative device that dramatically improves upon the shortcomings of conventional CO₂ and Erbium lasers. The 2910nm wavelength optimizes water absorption, dedicating 95% of its energy to ablation and only 5% to coagulation, which minimizes damage to surrounding tissue and significantly shortens recovery time. It is a cutting-edge rejuvenation platform that induces collagen and elastin regeneration while simultaneously improving pigmentation, pores, scars, fine lines, and elasticity. SH Plastic Surgery is the first in Korea to introduce UltraClear, delivering personalized treatments that surpass the limitations of conventional laser therapies by providing micro-tissue regeneration, early anti-aging prevention, and surgical-alternative lifting effects. In this article, we provide an in-depth analysis of UltraClear's technology, working principles, clinical evidence, and effects by mode from a medical perspective, while introducing its practical clinical applicability and future potential.

Face Designer, Dr. Sung-Hoon Kim, Director of SH Plastic Surgery

I've never experienced a laser like this before

"I've had many laser treatments... but this feels completely different.

The redness subsides quickly, and I can even wear makeup the next day...

It's amazing how both pores and elasticity improve at the same time."

Hello, I am Dr. Sung-Hoon Kim, Director of SH Plastic Surgery.

The words above...

are actually reviews that patients who received UltraClear treatments

uniquely share in common.

If conventional lasers

– offered good collagen regeneration but required long downtime, or

– had short downtime but provided weak results,

meaning they could only have one of these two characteristics,

UltraClear is the first device to satisfy both simultaneously.

That is precisely why SH Plastic Surgery came to introduce it for the first time in Korea.

UltraClear's Technical Principle – Innovation Created by the 2910nm Wavelength

The world's first 2910nm Erbium Glass fiber laser

Compared to conventional CO₂ (10,600nm) and Er:YAG (2,940nm),

it achieves precise ablation power + minimal thermal damage + rapid recovery all at once.

95% Ablation · 5% Coagulation

In the case of CO₂, 60% ablation · 40% coagulation

→ High thermal damage and delayed recovery

UltraClear

→ Induces collagen regeneration with almost no thermal damage

→ Allows return to daily life within a few days

Optimized water absorption rate

Highest reactivity to water within the skin

Acts only at the precise depth → Minimizes unnecessary damage

Increased collagen & elastin regeneration

In optical research, 2910nm

has been reported as the wavelength optimized for stimulating and activating fibroblasts in the dermis.

(Ref: Dermatol Surg. 2022;48:1123–1135)

Why UltraClear is the 'Next-Generation Laser'

1. Overwhelmingly fast recovery (Downtime Revolution)

Low rate of thermal coagulation

→ Reduced erythema (redness)

→ Minimal scabbing

→ Face washing and makeup possible the next day (varies depending on the mode)

2. Precise depth control is possible

Clear / 3DMIRACL / Ultra / Coring modes

→ Optimized according to skin type, age, and concerns

3. Addresses most signs of aging simultaneously

An all-in-one structure that improves

✔ Elasticity

✔ Fine lines

✔ Pores

✔ Pigmentation

✔ Skin tone

✔ Acne scars

✔ Skin regeneration

all with a single laser.

4. Truly creates an 'inconspicuous, natural look'

Without excessive peeling,

it creates only delicate micro-channels,

leading to a transformation where the skin "naturally improves."

5. Applicable even for middle-aged and older individuals who are reluctant to undergo surgery

Its effectiveness in helping improve drooping eyelids, deep wrinkles, and neck wrinkles

has been repeatedly confirmed in clinical studies.

(Ref: Lasers Med Sci. 2023)

UltraClear's 6 Modes

UltraClear is not just a "single laser,"

but a platform that integrates six laser devices into one.

Thanks to this, the following treatments are possible:

20s–30s: Pores, blemishes, and skin texture care

40s–50s: Improvement of wrinkles and loss of elasticity

60s: Addressing aging for those reluctant to undergo surgery

All age groups: Specialized acne scar treatment

The Effects of UltraClear Proven by Clinical Papers

Study 1

Full-face and neck resurfacing with a novel ablative fractional 2910 nm erbium-doped fluoride glass fiber laser for advanced photoaging

-> . 2024 Mar;56(3):249-256. doi: 10.1002/lsm.23764. Epub 2024 Feb 14

Conclusion:

Increased collagen regeneration

Improved elasticity

Reduced erythema and edema

Recovery speed is over 50% faster compared to CO₂

Study 2

The 2910-nm Fiber Laser Is Safe and Effective for Improving Acne Scarring

First published: 22 September 2024 https://doi.org/10.1002/lsm.23845Citations: 2

Conclusion:

Less painful than CO₂

Enables more natural skin resurfacing

Significantly less damage to the skin barrier

UltraClear is recommended for these people:

20s–30s

– Enlarged pores, fine lines, rough skin texture

– Those who want to prevent aging in its early stages

40s–50s

– Deep wrinkles, loss of elasticity, dull skin tone

– Those who need lifting + regeneration + pigment improvement all at once

60s and older

– Those who want definite skin regeneration without the burden of surgery

– Improvement of eyelids, under-eye areas, and neck wrinkles

All age groups with acne scars

– Coring mode has excellent effects on scar treatment

Reflections by Facial Designer Dr. Kim Seong-hoon

“UltraClear is not simply an ‘upgraded version’ of existing lasers.

This device is not about lesion-centered treatment, but rather revitalizing the skin's physiology itself.

I believe UltraClear has a high probability of

changing the standard of anti-aging treatments in the future.

In particular, the concept of preventative rejuvenation among younger demographics

will become more firmly established.

As the first in Korea to introduce UltraClear, SH Plastic Surgery

is researching the most ideal settings and mode combinations.

By analyzing more skin types in the future,

we plan to open the ‘era of sophisticated, customized skin treatment.’”
