What causes Varicose Veins?

Varicose veins are enlarged, swollen, and twisting veins that appear under the skin in the legs and may cause complications.

What are the risk factors that cause Varicose Veins?

  • Increased age
  • Sex hormones
  • taking birth control pills
  • Pregnancy
  • Standing or sitting for a long time
  • History of family members

How to treat Varicose Veins

1. Laser Treatment (Nd YAG)

which is very popular in Europe and America. The best technology nowadays is suitable for small varicose veins. The laser will pass through the upper surface to the area of the varicose veins precisely, causing the blood vessels to become hot and destroyed. With the cooling gas, the pain is reduced by adding coolness to the upper skin. The treatment does not damage the skin and can cure varicose veins safely, quickly, and most efficiently, without a scar. After the treatment, some varicose veins will fade away immediately, and some may take 2-3 days to disappear.

2. Sclerotherapy

Sclerotherapy causes varicose veins to collapse and eventually fade away by injecting a solution directly into the vein. It is recommended for a 2-3 mm vein. After treatment, you may experience minor side effects, such as itching, red areas at the injection site, and bruising.

3. Vein Stripping

This surgical procedure is recommended for large and long varicose veins. Even if this procedure is safe and low-risk, there are always side effects associated with surgeries. These include bleeding and inflammation at incision sites

Melasma, freckles, and age spots are caused by overactive pigment cells. These cells produce melanin, a substance that darkens the skin. Freckles are tiny, brown spots that usually appear on sun-exposed areas early in life and fade over time. Age spots are generally seen later in life and tend not to fade. Melasma occurs most frequently in women of reproductive age. It is common in women with darker complexions who live in areas of intense ultraviolet (UV) radiation exposure.

All these skin discolorations can cause considerable cosmetic disfigurement and psychological distress. Studies have also shown that they negatively affect emotional well-being, social life, and leisure activities.

What causes Melasma?

The pathogenesis of melasma needs to be better understood. Contributing factors include darker skin prototypes, ultraviolet (UV) radiation, hormonal factors (e.g., pregnancy, oral contraceptives), genetic predisposition, cosmetic use, thyroid dysfunction, and antiepileptic medications. Melasma may be caused by more biologically active melanocytes in the affected skin.

Clinical features

Melasma can present with irregularly shaped, hyperpigmented spots less than 5 mm. Depending upon the site of melanin deposition in the skin, the color varies from light brown to dark brown or ash/blue. The deeper site, such as dermal melanin, has a more grey/blue hue.

The spots are often confluent and symmetrically distributed. They are typically seen on sun-exposing skin areas of the face. Melasma caused by pregnancy usually regresses within a year after delivery.

Treatments

Treatments include skin-lightening agents, chemical peels, and laser and light-based therapy. Continued application of topical skin-lightening agents for up to six months may be required before a reduction in pigmentation occurs.

Therapy for melasma must be combined with sun protection measures, which include sun avoidance, wearing sun-blocking clothing and hat, and sunscreens that block both ultraviolet A (UVA) and ultraviolet B (UVB) with sun protection factor (SPF) 30 or higher. Sunscreen should be applied before going out and reapplied every two hours while being outdoors.

First-line therapies for melasma are skin-lightening agents and topical retinoids. Topical skin-lightening agents are the mainstay of treatment of melasma. Skin-lightening agents commonly used to treat melasma include Hydroquinone, Azelaic acid, Mequinol, and Kojic acid. Tretinoin stimulates the turnover of skin cells, decreases melanin transfer, and allows greater penetration of other active ingredients. Topical retinoids should not be started or continued during pregnancy because they are known teratogens and may cause congenital malformations.

New skin-lightening agents contain potent ingredients from natural plants from France, Spain, Africa, Canada, and the Swiss Alps. They inhibit the activity of tyrosinase and help melasma regress in fourteen to sixty days. They also claim to reduce some side effects seen in older skin-lightening agents.

Laser and light source-based therapy

Lasers and light-based therapies for treating melasma can be used in refractory cases.

HELIOS II: What is it, and how does it work?

Helios II is a laser emitting device from Korean LASEROPTIK, which emits fractional Q-switched Nd: YAG of 1064-nm and 532-nm wavelengths. Helios II’s targeted chromophore is melanin and can be used with pigmented skin lesions. The 532 nm frequency-doubled Nd: YAG laser mode is suitable for red, yellow, and orange tattoos and can remove more epidermal lesions, such as freckles and sun spots. The 1064 nm Nd: YAG laser is suitable for black and blue tattoos and can treat deeper lesions, such as melasma on the dermal layer of skin.

Helios II has a Fractional Handpiece and Diffraction Optical Element (DOE), which claims to minimize pain and side effects, such as post-inflammatory hyperpigmentation, scarring, etc. The Fractional Handpiece divides one laser beam into 81 small beams, leaving the surrounding skin intact, reducing the heat applied to the skin and minimizing downtime. The Diffraction Optical Element (DOE) allows HELIOS II to deliver an even and uniform laser beam.

Helios II also has a ‘Soft Peeling’ effect. It applies a light carbon coating over the skin and then removes the carbon through a burst of light from the laser. Dead skin cells, makeup residue, clogged pores, oil sebum, and blackheads are removed. The benefits of ‘Soft Peeling’ include reduced pore size, even skin tone, reduced sebum production, reduced fine lines and wrinkles from collagen stimulation, and healthy glowing skin with zero downtime.

Indications of HELIOS II

  • Melasma
  • Freckles
  • Tattoos
  • Nevus of Ota
  • Becker’s nevus
  • Lentigo
  • Uneven skin tone
  • Café au Lait spots
  • Age spots
  • Skin rejuvenation

Treatment sessions

Often, eight or more treatment sessions are required to achieve maximum improvement, but with HELIOS II’s technology, three or five treatment sessions may be necessary for deeper skin lesions. Additional treatment sessions are usually separated by four to six weeks. Subsequent treatments may need higher laser energy settings to remove residual pigments.

Post-treatment Care

The preferred post-treatment care of the laser site consists of the daily application of a bland, occlusive ointment such as petrolatum to maintain wound moisture. Moisture promotes wound healing, and application should continue until the site is fully healed. Crusting and scabbing are normal and typically persist for one to two weeks. Cool packs may help minimize discomfort after treatment. Sunscreen and sun-protecting clothing should be used to minimize the risk of post-inflammatory hyperpigmentation. Strict sun protection should be continued for at least several weeks after treatment.

Safety of HELIOS II

HELIOS II is approved by the Thai FDA, US FDA, European Economic Area’s Conformité Européenne (CE marking of EEA), and Korean FDA.

Does Laser Hair Removal completely get rid of hair?

In today’s beauty trend, girls want to be beautiful and have clean skin but have hair as an obstacle. Some people rely on plucking or shaving methods because they are easy. The thing that follows is the inflammation of the skin. Also, using hair removal chemicals may cause inflammation and irritation. Girls now prefer laser hair removal until the hair follicle is destroyed and permanently eliminated.

There are 2 methods for permanent Hair Removal

1. The electrolysis method uses the needle inserted into the hair follicles individually and releases the electric current to destroy the hair roots. This method is painful and time-consuming because they must insert the needle into the hair follicle individually. The risk of scarring is relatively high because inserting the needle into the hair root is a random insertion method without knowing where the hair root is. This method may leave scars after treatment.

2. High-intensity light or laser is a hair removal method using heat energy from the light to destroy the hair roots. The light can destroy specific hair roots since the hair follicle area has a color-creating cell called Melanocyte, which acts as a light conductor or a light energy absorber to the hair follicle area

Nowadays, Fotona-XP Focus laser technology is an Nd: YAG laser with a wavelength suitable for hair removal. This technology does not cause wounds. It is a very safe laser and has been certified by international standards in Europe and America (US-FDA). Fotona-XP Focus laser can be used effectively for permanent hair removal. It is suitable for all skin colors, including dark skin, without causing wounds or burns. With repeated treatments, the hair will be permanently removed.

How long does Laser Hair Removal take?

It depends on the area. For example, underarm hair removal takes only 2-3 minutes, while treating the back or legs may take approximately 1 hour.

What factors does the treatment depend on?

It depends on hair color and skin type. Dark black hair removal is more effective than lighter hair.

How many treatments are needed?

Laser hair removal typically destroys 15% to 30% of hair after the first treatment. Generally, it requires 5 to 8 sessions, with treatments spaced every 4-6 weeks. While some individuals experience complete hair disappearance, others may have 10 to 20% fine and sparse hair remaining.

How does the skin change after Laser Hair Removal?

The skin around the pores may become red and slightly swollen within 30 minutes after treatment. This will subside within a day. Applying a cold compress can help reduce the burning sensation. Post-treatment, the skin does not bleed or cause wounds.

How should I care for my skin after Laser Hair Removal?

Avoid using soaps or creams that irritate the skin, such as Retin-A or AHA. Sun exposure should be minimized, and sunscreen should be applied to the treated area.

What happens to the hair after treatment?

Hair will gradually push out of the skin within 2 weeks after treatment.

How should I prepare before Laser Hair Removal?

One week before treatment, avoid unnecessary outdoor activities to prevent sun exposure. Please don’t pluck or wax the hair. If needed, use shaving up to two or three days before laser treatment.

Cheek Lines or Nasolabial Fold

The nasolabial fold is the deep crease running from either side of the nose towards the corners of a mouth. This crease becomes more noticeable as part of the natural aging process. Fat is lost from the cheeks, reducing skin volume and making this fold appear deeper. Repeated smiling or having a “big smile” may result in permanent, deep creases in this area. Many treatment procedures to correct nasolabial fold include;

  1. Dermal filler injection
  2. Fat graft
  3. Laser tightening
  4. Surgery

Dermal filler injection is the best choice for mild to moderate tear troughs, as it does not require downtime or recovery.

A good candidate for Nasolabial Fold Filler

  1. Mild to moderate nasolabial fold without skin conditions, such as infection at the injection area.
  2. No history of allergic reaction to hyaluronic acid dermal filler
  3. Realistic expectation

Preparation for Nasolabial Fold Filler

  • consultation with the doctor about your expectation
  • Stop taking anti-inflammatory medication such as Ibuprofen or aspirin for at least two weeks or some vitamin and herbal supplements that may increase bleeding during and after the procedure

The procedure of Nasolabial Fold Filler

The procedure typically takes less than half an hour. Nasolabial fold filler is painless and can be performed under local anesthesia. The total time of examination and injection is usually less than 10-15 minutes.

Post-procedure Care for Nasolabial Fold Filler

  1. The patients should avoid intense or extended pressure within the treated area
  2. The patients should be informed about aftercare, such as avoiding massage, strenuous physical activity, and exposure to extreme cold or heat for up to six hours post-treatment
  3. It is important to schedule follow-up sessions to assess the clinical result. Touch-ups may be performed in the follow-up sessions if required.

Risks and Complications for Nasolabial Fold Filler

The risks and complications are sporadic under specialist care, including:

  • Pain
  • Infection
  • Swelling and bruising
  • Over-filled or Asymmetry
  • Tissue necrosis or Blindness

Recovery from Nasolabial Fold Filler

After treatment, pain is minimal. Patients can return to work in a day, and the results can last for a year or more.

A tattoo is visible and permanent skin pigmentation secondary to the deposition of exogenous pigment within the dermis.

In the past, methods for tattoo removal were limited to excisional and destructive procedures (e.g., surgical excision, dermabrasion, traditional ablative lasers). The discovery of the theory of selective photothermolysis has contributed to advances in laser therapy for tattoos.

Quality-switched (Q-switched, QS) lasers are the preferred first-line treatment for most tattoos. It has been the standard of care for tattoo removal for over two decades. The range of laser wavelengths available in QS devices and the short pulse durations of these lasers allow for the effective treatment of tattoos with low risk for scarring. Q-switched lasers generate short nanosecond bursts of laser light that break apart tattoo pigment in the dermis. Shattered tattoo pigment fragments either remain in the dermis or are removed by the lymphatic system.

Quality-switched lasers are available in various wavelengths and are selected based on tattoo color(s). These are Q-switched laser-used tattoo removal;

  • 532 nm frequency-doubled Nd: YAG laser
  • 694 nm ruby laser
  • 755 nm alexandrite laser
  • 1064 nm Nd: YAG laser

(Nd: neodymium-doped; YAG: yttrium aluminum garnet)

More than one laser is usually necessary to treat tattoos with multiple colors. In general, yellow and orange pigments are the most difficult to remove, whereas blue and black pigments tend to be the easiest to remove. Tattoos with pigments placed deeper and more extensively in the dermis are often more challenging to treat. More treatment sessions and higher fluence settings may be necessary for the removal.

PRP Hand Rejuvenation Treatment

What kind of story do hands tell? Do they express pain and fatigue? Do they reveal an injury, arthritis, or wrinkles and age spots? PRP is a treatment to invest in before scheduling a surgical procedure. PRP can bring dramatic healing to the hands quickly and effectively.

PRP Treatment for Hand Rejuvenation

Hands show one’s age. They come into contact with harsh environmental conditions and are subject to injury. PRP treatments for hand rejuvenation offer benefits that enhance the appearance of hands.

Conditions Treated using PRP for Hand Rejuvenation

Those struggling with any of the following can benefit from PRP injections in the hands:

  • Excessive wrinkles
  • Age or liver spots
  • Loss of volume in hands
  • Injuries
  • Arthritis
  • Carpal tunnel syndrome
  • Trigger finger

PRP injections use the patient’s plasma to help repair skin issues and injuries in the hand. This process provides a safe, natural, quick remedy for unsightly hands. PRP is used mainly for rejuvenation and swift healing purposes.

Hand Injuries

Not only do the hands suffer from aging, but they also suffer from pain. This pain can also come from arthritis, carpal tunnel syndrome, or hand, wrist, and finger injuries and can happen at any age. PRP treatments provide aid in restoring the needed strength, mobility, and range of motion necessary in the hands, fingers, and wrists.

Treatment

The PRP procedure is straightforward and quick. It’s very similar to taking a sample of an individual’s blood. However, 30-60 ml of blood is drawn from the patient’s arm, collected into a tube, and placed into a centrifuge. The blood sample is spun around to remove the plasma and platelets from the blood until the rich plasma separates from the blood particles.

After numbing the area, the plasma is injected into the patient’s hand. Unlike a surgical operation, PRP allows patients to resume daily activities quickly.

Types of Hand Aging

  • Intrinsic. This type of aging occurs naturally as we age. The hands show decreased skin volume, less elasticity, more wrinkles, and more apparent veins, tendons, and joints. Intrinsic aging affects the deep tissue within the hands.
  • Extrinsic. This happens to the above layers of the skin, known as the epidermal and dermal, or surface, layers of the skin, which can be caused by sun exposure, strong chemicals such as nicotine, diet, and lifestyle choices.

Recovery

After a PRP procedure, a noticeable difference can be seen within a month—the results usually last about twelve months. Therefore, treatment is advised every six months to a year, depending on the patient’s desires and needs.

Prevention

Before the hand’s aging progresses, PRP treatments can help prevent the damage that occurs naturally. Of course, extrinsic aging can be prevented or delayed by applying moisturizers and sunscreen products daily.

Other Alternatives

Other methods for improving hand appearance can include surgeries and botox. However, those options might be necessary depending on the patient’s situation. Recovery time is less with PRP and physical therapy, and scarring issues are minimal.

Of course, surgical fees are much more expensive than any PRP treatment. The cost of the procedure is discussed during the consultation.

What is Keloid Removal?

Keloid removal is the treatment to make the keloid flattened, softened, or shrunk. Keloids can be hard to get rid of in the body. Sometimes, they return after treatment. Most cases require using a combination of treatments for the best results. Different treatments work for different people, such as:

  1. Intralesional steroid injection
  2. Vascular and pigment laser therapy
  3. Surgical excision

Procedure of Nonsurgical Keloid Removal Therapy

The treatments include laser and medical injection, which are painless and can be done under topical anesthesia. The laser time is approximately 15 mins. The laser treatment can be performed around 2-4 weeks apart for each session without any severe side effects depending on the skin condition, and a medical injection can be administered every month. The patient should do a laser at least six times for maximum results.

A good candidate for Keloid Removal

Patients with keloid without any skin condition in that area are good candidates for keloid removal.

Post-treatment Care for Keloid Removal

The preferred post-treatment care of the laser site consists of daily application of a bland ointment such as petrolatum to maintain skin moisture. Moisture promotes skin healing, and the application should continue until the site fully heal.

Sunscreen and sun-protecting clothing should be used to minimize the risk of post-inflammatory hyperpigmentation. Strict sun protection should continue for at least several weeks after treatment.

Risks and Complications for Keloid Removal

Crusting and scabbing are normal and typically persist for one to two weeks. Cold packs may help minimize discomfort after treatment. Other serious complications included

  • bleeding or bruising
  • skin hyperpigmentation and hypopigmentation
  • scar

However, these conditions are sporadic.

Recovery from Keloid Removal

Crusting and scabbing are normal and typically persist for one to two weeks. Cold packs may help minimize discomfort after treatment. There will be a mild, ticklish sensation during the treatment, but this should not affect you or the procedure itself. Results will improve after each subsequent session, with the number of courses depending on the severity of the keloid.
