Drs.Woo&Hann’s Skin Clinic received a certificate of appreciation from the US Department of Defence for the medical services it has provided over the years.

Laser hair removal
This is a procedure to remove unwanted hair by the means of a Long-pulse Alexandrite laser and Long-pulse Nd:YAG laser through the surface of the skin, disabling hair follicles. Installation of two different epilation lasers at one clinic is very special. The advantage of dual installation is that we are able to remove any type of hair from fine to thick.

Spider vein & broken vessel removal
A laser beam passes through the skin and penetrates a targeted vessel. The laser energy heats up and coagulates blood inside the vessel and underlying collagen is stimulated. The skin is protected during the laser treatment by Dynamic cooling device which sprays a cool liquid onto the skin.

Tattoo removal
We use a Q-switched Nd:YAG laser to fade tattoos. This has two separate wavelengths so that different colored tattoos can be treated. Black ink absorbs all the laser light and therefore is most effective. Multi colored professional tattoos is less effective and several sessions of treatment are required.

Common mole removal
Updated laser or surgical excision related technologies are available for removal of unwanted mole without pain. The remaining scar is quite minimal and negligible.

Acne scar treatment
Acne scar removal can be performed by Ablative procedures or Non ablative procedures.
Significant improvement may also be achieved both by lasers which build up skin collagen without sacrificing the skin surface(Smoothbeam laser) or by techniques which ablate the skin(Erbium:YAG laser and Scanned CO2 laser). Some assistant procedures such as subscision and selective chemical peeling may be combined to get a better result.

Since 2005, we’ve established fractional laser system, so called to Fraxel, improve a variety of scars, especially for acne scars. There are a lot of advantages of Fraxel compare to other scar treatment lasers. If you click on the Fraxel section, you can get a more detailed information.

Chemical peeling
It is a process whereby a chemical solution is applied to the surface of the skin to peel away the top cell layers which will be replaced during the healing process with a fresh , new skin surface. New techniques and technologies in chemical peeling offer safe and effective ways to improve the texture of skin. Some uperficial blemish marks can also be removed by chemical peeling.

Spider vein & broken vessel removal
This name is derived by absence of downtime during the procedures. It also called glycolic acid peeling. The lunchtime peel causes an exfoliation of the outer, dead layers of the skin. The younger skin call emerge beneath, thereby promoting more even skin tones, and complexions. The effects are gradual, usually requiring a series of peels.

Tattoo removal
Microdermabrasion is a new approach to skin resurfacing that stimulates the production of new collagen. It is a non-surgical treatment that does not require an anesthetic.

Common mole removal
Our practice includes the most up-to-date program for acne skin care. All this procedures are performed by physicians, nurses and trained medical estheticians. The superficial chemical peel or microdermabrasion are also performed by physicians.

Acne scar treatment
It is a sort of electric and chemical treatment that let ionized L-ascorbic acid salts(Vitamin-C) penetrate deep into the skin. Vitamin-C acts as an antioxidant, so it can diminish blemished areas and provide skin whitening.

Acne scar treatment
Starlux is not only a model of IPL system, but also a multi functional skin rejuvenation system.
We’ve been used Palomar Medilux that is a previous model of Starlux more than 3 years. Recently we've renovated it to Satrlux (new generation model). Due to the cooling effect and single pulse mode, the pain is very much decreased compare to other models of IPL. And, there is another reason that we decided to buy Starlux, that is because Starlux can attach IR(Infrared) handpiece. This new handpiece is designed for skin tightening and lifting without discomfort. It enables facial lifting without scar. Actually, Starlux IR handpiece can not make same effect like operation, but we can expect quite impressive result.

The new Palomar StarLux™ Pulsed Light System is emerging as a photofacial system with power that surpasses many cosmetic lasers, according to users. Palomar’s unique RejuveLux™ process, one of several applications possible with the StarLux, consists of the treatment of pigmented and vascular lesions on the face, chest, arms and other large areas ? with a resulting improvement of skin tone and texture. “In my practice, the StarLux system has been fast, effective, versatile and user-friendly,” said R. Rox
Anderson, M.D. of Massachusetts General Hospital, Boston, Mass. “I’m impressed with how far filtered xenon flashlamps have come, since their humble beginningsover a decade ago for skin treatment. StarLux is now my favorite way to treat facial telangiectasia and rosacea without causing purpura. The combination of integrated skin cooling, high pulse energy, tunable pulse duration without splitting up the pulse, speed, and a wide range of handpieces tailored for specific indications makes this device very useful. It has apparently no major glitches.” “The StarLux is the next generation in photofacial technology,” reported Robert A. Weiss, M.D., assistant professor of dermatology at Johns Hopkins University School of Medicine. “The LuxG handpiece is optimized to target oxyhemoglobin, epidermal pigment and water, which produces desirable results for my patients seeking photorejuvenation.” Immediately after RejuveLux treatment, there is a slight darkening of the unwanted pigment (lentigines, actinic bronzing, etc.). Within two to three minutes,
there is usually mild to moderate erythema around the individual pigmented lesions, and within two to three days, there is usually a mild desquamation of the unwanted pigment. Vessels generally undergo blanching and then either fully or partially resolve in about 10 - 14 days. Areas of diffuse flushing or erythema gradually fade, leaving skin with a normal appearance.
StarLux is able to deliver high energy to the target pigment and oxyhemoglobin due to its active contact cooling feature, which chills the handpiece’s sapphire tip to as low as 4°C. The skin is cooled throughout treatment, permitting the operator to deliver high-energy pulses while providing maximum comfort and safety to the patient. “The active cooling provides good epidermal protection and patient comfort during treatments,” added Dr. Weiss. “Also, having the ability to vary the pulsewidth and fluence independently creates the opportunity to treat with a wide variety of parameters, including longer pulsewidths. This ultimately means more flexibility in addressing the patient’s needs and optimizing the results.” Another high energy and safety feature is the StarLux’s Smooth Pulse Technology. StarLux delivers light over one smooth pulse duration, rather than the multiple power spikes (which may damage skin) that other technologies use. This keeps the epidermal temperature lower, permitting safe delivery of greater amounts of energy, which are more effectively absorbed by pigment and blood, producing greater efficacy compared to other technologies. http://www.palomarmedical.com/

We can attach on Starlux a variety of application-specific handpieces to one compact base unit, allowing expand treatment repertoire. Palomar systems deliver pulsed light over one smooth pulse duration, rather than the multiple power spikes (which may damage skin) that other technologies use. This smooth pulse technology keeps the epidermal temperature lower, for far more comfortable treatments. It also allows for the safe delivery of greater amounts of energy, which is more effectively absorbed by pigment and blood, producing greater efficacy.

In most light-based treatments, up to 60% of light is reflected back off the skin surface, and not delivered to the treatment target. But Palomar’s patented Photon Recycling process uses mirrors within the handpiece to recapture this scattered light and send it back to the treatment area for a more efficient delivery of energy.

The Palomar Lux handpieces are designed to filter light in the optimal bands of the spectrum for specific treatments. For example, the LuxRs™ filters light to provide the ideal spectrum for permanent hair reduction on all skin types. The LuxG™ filters light to provide the ideal spectrum for vascular lesions and epidermal pigment. This allows you to choose the best handpiece for the treatments you seek to deliver.

It is pliable substances that can be injected into the skin to erase fine line and wrinkles, plump lip, improve scars, elevate deepfolds and repair various facial imperfections through a tiny needle. The hyaluronic acid in filler is nearly the same as that found in the body. Botox is a purified chemical that regulates the activity of wrinkle producing muscles. It's been used safely in medicine for over 10 years with no serious side effects documented.

Indications of botox
- Wrinkle treatment
- Reshaping of lower face by masseter muscle activity reduction.
- Hyperhidrosis

Polaris WR(Wrinkle Reduction) utilizes Syneron's proprietary ELOS (Electro-Optical Synergy) technology, which combines optical energy and electrical energy to enable a wide range of highly efficient, safe and cost-effective medical aesthetic treatment systems. It stimulates new collagen growth and creates a smoother, softer appearance to the skin. The unique properties of combining and layering laser and RF is described as Matrix Heating, which results in the desired and profound heating of the dermis necessary for wrinkle reduction.

The post treatment results demonstrate significant reduction in the signs of aging. Improvement of wrinkles in these cases is dramatic. Polaris WR helps to remove crow's feet around the eyes, smoker's lines around the mouth and all other wrinkles!!! The unique properties of combining and layering laser and RF are described as matrix heating, which results in the desired and profound heating of the dermis necessary for wrinkle reduction.
Treatments are done in 3-4 sessions. The Polaris WR is ideally suited for those patients with wrinkles, looseness and skin texture concerns, such as large pores. The Polaris WR can diminish moderate wrinkles, reduce enlarged pores, improve superficial acne scarring, and tighten skin laxity of the face and neck without surgery. All the people are able to return to work immediately after the procedure. The unique properties of combining and layering laser and RF are described as matrix heating, which results in the desired and profound heating of the dermis necessary for wrinkle reduction. This device approved by the FDA for wrinkle reduction.

IPL, also known as Photo Rejuvenation, is a non-invasive, non-abrasive treatment that uses selected wavelengths and light pulses to stimulate collagen production, increase moisture and improve circulation in the skin. When collagen is increased, signs of aging such as fine lines and large pores are reduced. It provides multiple wavelengths composing white light (not laser light) that remove sunlight induced freckles, most benign brown pigments like sun spots, uneven skin tone, rough skin texture, acne/scarring and other common skin conditions, and broken vessels. Also, it is effective for long-term hair removal. IPL can be performed over a lunchtime visit without any subsequent down time. It takes approximately 3 to 4 treatments, scheduled 3 weeks apart, to get the desired effect. In short, in terms of superficial problems, it works great, IPL can allow practitioners to deliver the right amount of energy to each blood vessel and without causing much risk to the skin. How the treatment works is light energy is delivered through a special hand-piece, with filters, to the specific vessel. Light is then delivered in a series of short and/or long pulses. This light energy is then absorbed by the blood vessels, so the heat caused by the light induces a clogging of the blood vessel and eventually shuts down that.

Superficial pigment responds easily to IPL, whereas deep pigment such as melasma may require combining with other methods.
