Clinic opening

Lasers have the characteristic of being able to selectively destroy only the desired area by focusing a large amount of light energy on a small area, and are effectively used for various diseases depending on the type of laser. Currently, the dermatology and plastic surgery department of Ilsan Paik Hospital has carbon dioxide laser, vascular laser, ND YAG laser, fractional carbon dioxide laser, IPL (intense pulsed light), excimer laser, and high-intensity focused ultrasound (HIFU). We use various lasers in combination to treat pigment diseases such as age spots, moles, lentigo, freckles, and freckles, vascular lesions such as hemangioma, flame nevus, and rosacea, scars, and wrinkle improvement.

The laser clinic treats a wide range of skin diseases such as atopic dermatitis, psoriasis, vitiligo, contact dermatitis, allergic diseases, hair diseases, skin tumors, hereditary diseases, pigmentary diseases, vascular diseases, acne, and skin aging. It also helps in diagnosing diseases of various internal organs that appear as symptoms. Non-invasive testing equipment, such as ultrasound devices for dermatology and laser Doppler for measuring skin blood flow, are being applied to the diagnosis of skin diseases, and many new laser equipment and phototherapy equipment have been introduced. The laser clinic uses various laser treatment machines to treat vascular diseases, pigmented diseases, and skin tumors. Ilsan Paik Hospital conducts treatment on a reservation system after making a treatment plan through consultation in advance. The devices and indications currently in stock at Ilsan Paik Hospital Laser Clinic are as follows.

Carbon dioxide laser (CO2 laser)

It is effective in treating moles, warts, raised age spots (seborrheic keratosis), small lumps, hidradenomas called ‘water warts’ under the eyes, and milia. Apply anesthetic ointment for 30 minutes, or for large lesions, anesthetize with a local anesthetic injection and then perform laser treatment. If the treatment is too deep to remove moles and warts at once, it may leave scars, so the treatment is performed to the extent that no scars remain. If lesions remain or recur, reoperation is performed after 6 weeks. After the procedure, waterproof tape must be worn for about a week, and light washing of the face is allowed during this time.

Q switch Nd:YAG laser

This is a laser that selectively removes melanin pigment using two different wavelengths of the laser. It is effective in treating eyebrow tattoos on the face, tattoos on the body, blue dots such as the nevus of Ota, age spots, freckles, and brown spots. During the procedure, anesthesia as mentioned above is administered and then treatment is performed. A thin scab forms, which naturally falls off over a week or two and is treated. Erythema in the treated area may last for as little as a month or as long as 2 to 3 months. At this time, you must pay attention to UV rays to prevent discoloration.

V-star laser (Pulsed Dye Laser (V-star Smart pulse))

The V-Star laser with a wavelength of 585 nm is selectively and strongly absorbed by hemoglobin (oxyhemoglobin), enabling the treatment of vascular lesions and reducing damage to other tissues, making it safe to treat. In addition, various pulses from 0.5ms up to 40ms are used to treat vascular lesions (port-wine stains, hemangioma, angiectasia, rosacea, etc.) as well as red acne marks, hypertrophic scars, keloids, and warts. is possible. The advantage of this laser is that there is a low probability of bruising during the procedure, recovery time is short, and daily life is possible.

IPL

IPL is an abbreviation for 'intense pulsed light' and its difference from existing laser treatments is that light of various wavelengths is emitted at the same time, so it can treat pigmentary diseases such as freckles and blemishes, vascular problems such as capillary dilatation and facial flushing. It is possible to maintain elastic skin by increasing the synthesis of skin collagen. After treatment, only when the pigment is dark, a few thin scabs appear and disappear on their own. This can be sufficiently covered with makeup, and it is possible to wash your face on the day of treatment, so it does not cause any significant disruption to your daily life. Of course, it is difficult to solve 100% of the problems listed above with IPL, but satisfactory results can be obtained if treatment is planned with a reasonable goal. Furthermore, maximum results can be obtained if combined with existing laser treatment.

Laser treatment involves applying heat or energy to the skin to create a type of wound, so caution must always be taken during recovery. A scab will form on the wound area after the laser treatment, and the scab should never be forcibly ripped off. It is best to leave it until it falls off naturally. If the scab falls off before the wound heals, the wound recovery process will be interrupted midway and a scar will inevitably remain. Additionally, erythema temporarily remains in the area where the scab has fallen, and if this area is exposed to ultraviolet rays, the erythema may persist for a long time or darkening pigmentation may remain.

Therefore, you should always make efforts to protect the laser treatment area from sunlight, such as always applying sunscreen and wearing a wide-brimmed hat when doing outdoor activities for long periods of time.

◎ Carbon dioxide laser: Used to treat moles, age spots, warts, and sweat ducts.

◎ Vascular laser: Mainly used to treat red lesions and scars, such as hemangioma, nevus flames, rosacea, and telangiectasia.

◎ N.D. Glaser: Used to treat lentigo, freckles, freckles, Nevus of Ota, tattoos, etc.

◎ Fractional carbon dioxide laser: Used to treat acne scars and scars.

◎ IPL: This is a device that emits powerful light of various wavelengths. Although it is not a laser, it can effectively remove the desired lesion using a filter. It is used for pigmented lesions such as freckles and lentigo, and vascular lesions such as rosacea and flushing.

◎ Excimer laser: Can be used to treat vitiligo, psoriasis, and alopecia areata.

◎ High-intensity focused ultrasound (HIFU): It has a skin lifting effect by using ultrasound to deliver energy to the epidermis, dermis, and fascia layers.
