Laser Treatment: What Is It, How It Works, 4 Benefits, 3 Types & Cost

Lasers are versatile skincare technologies designed to address various skin conditions involving the skin, hair, and body. The selection of laser types varies depending on the issue, including acne, acne scars, pigmentations, hair removal, and tattoo removal.

Choosing the appropriate laser treatment depends on your individual needs and skin type.

Here is a comprehensive guide to understanding laser treatments in Singapore for your skin, face, and body.

What is Laser Treatment?

Laser treatment is a non-invasive procedure that utilises concentrated beams of light to address various cosmetic and medical skin concerns. These laser treatments can resurface the skin and effectively remove blemishes by focusing high-intensity light on specific areas. This helps reduce age spots, scars, and wrinkles and balance skin tone.

Different laser treatments are distinguished by their unique features, such as wavelength, pulse width, and the rate at which the light beam is delivered, which can be tailored to suit individual needs and skin types. Laser treatments offer precision, allowing for targeted action with minimal damage to the surrounding healthy skin, making them a good option for achieving smooth and rejuvenated skin.

Dr Justin Boey, Medical Director of Sozo Clinic, provides tailored laser treatments, using his expertise to select the suitable laser technology for each patient’s unique skin concerns. Dr Boey’s in-depth knowledge of laser therapy enables him to offer precise and safe treatments for diverse skin conditions.

How Does Laser Treatment Work?

Lasers emit light energy at specific wavelengths that the target tissues can absorb. When the light is absorbed, it converts into heat, which can destroy or modify the tissues without affecting the surrounding areas. Different wavelengths correspond to different penetration depths and absorption characteristics, making certain lasers more suitable for particular treatments.

For example, shorter wavelengths are often used for targeting pigmented lesions. In comparison, longer wavelengths might be utilised for deeper skin structures or hair removal. This ability to select the appropriate wavelength allows laser treatments to be tailored according to the specific requirements of the skin concern being addressed.

Benefits of Laser Treatment

Laser treatments offer a range of advantages. Some of the most notable benefits include:

1. Precision

One of the main advantages of laser treatments is their precision in targeting specific areas, which limits the impact on surrounding healthy tissues. This focused approach allows treating sensitive or delicate areas with less likelihood of side effects compared to broader, more invasive procedures. This accuracy improves patient outcomes, making laser treatments an option for those who address specific skin concerns effectively and safely.

2. Improved Skin Texture

Lasers play a significant role in skin rejuvenation by enhancing skin texture and reducing visible imperfections. By promoting collagen production and targeting damaged skin layers, laser treatments result in a smoother and more even skin surface. Precise laser applications can significantly diminish imperfections such as age spots, acne scars, and uneven skin tones, resulting in a youthful, revitalised appearance.

3. Faster Healing

The precision and control offered by laser treatments are key factors in promoting quicker healing times. This targeted approach reduces the risk of inflammation and scarring, allowing patients to experience faster recovery. Consequently, patients can resume their daily activities earlier than with more invasive procedures.

4. Stimulates Collagen Production

Certain laser treatments help to stimulate collagen production, an essential protein that maintains skin elasticity and firmness. Laser treatments can use precise wavelengths of light to penetrate skin layers and trigger the body’s natural healing mechanisms, prompting increased collagen production. This rejuvenating effect refreshes the skin, leading to a youthful, healthier appearance.

Types of Laser Treatments

When considering laser treatments, it is essential to understand the specific types of lasers and their intended applications. Here are the main types of lasers commonly used in skincare and their uses:

• CO2 Laser: The CO2 laser is commonly used for skin resurfacing and scar removal. This laser emits infrared light that precisely targets the skin’s deeper layers, promoting collagen production, which results in smoother and more youthful-looking skin. Its efficacy makes it suitable for treating deep acne scars, uneven textures, and fine lines.
• Erbium Laser: Known for reducing wrinkles and fine lines, the erbium laser is effective for individuals with moderate skin concerns, as it removes surface-level skin layers with minimal heat damage to the surrounding tissue. This quality makes it a preferred option for patients with sensitive skin or those seeking quicker recovery time.
• Q-switched Laser: This laser removes tattoos and targets pigmentation and skin blemishes. Q-switched lasers generate rapid, high-intensity pulses of light that fragment tattoo ink or pigmented areas into smaller particles, which the body naturally eliminates. This type of laser is versatile and effective in addressing unwanted pigments and ink of various colours.

Ablative vs. Non-Ablative Lasers

There are two main categories of lasers: ablative and non-ablative. Ablative lasers are more invasive, as they remove the outer layers of skin to stimulate collagen production and resurface the skin’s texture. Non-ablative lasers, conversely, do not damage the top layer of skin but rather penetrate deeper into the skin to target specific concerns.

The table below shows the differences between the two types of lasers:

Laser Type	Skin Layers Affected	Recovery Time	Common Issues Treated
Ablative Lasers	Epidermis and Dermis	Longer (days-weeks)	Wrinkles, deep scars, sun damage
Non-Ablative Lasers	Dermis	Shorter (hours-days)	Fine lines, slight pigmentation, mild acne scars

Cost of Laser Treatment

Understanding the cost of laser treatments can help you plan and budget effectively. Here is a breakdown of the costs associated with various laser treatments in Singapore:

• Skin Resurfacing: Prices for CO2 laser treatments like Fractional CO2 laser, commonly used for skin resurfacing, range from SGD 250 to SGD 1000 per session. Factors such as the clinic’s location, the complexity of the treatment, and the specific condition being treated can affect the overall cost.
• Hair Removal: Q-switched lasers effectively remove unwanted hair and generally cost between SGD 150 and SGD 600 per session. The price variation depends on the treatment area and the clinic’s technology.​
• Tattoo Removal: Laser tattoo removal costs vary significantly based on the size and colour of the tattoo and the type of laser used. On average, sessions can range from SGD 200 to SGD 500, with complete removal often requiring multiple sessions depending on the tattoo’s characteristics​.

During consultations, Dr Boey provides a detailed cost breakdown based on the individual’s treatment plan, allowing for an informed decision.

Conditions Treated with Laser Therapy

Laser therapy offers versatile solutions for various skin conditions, allowing individuals to address specific concerns precisely and effectively. These treatments target underlying issues, improving appearance and confidence. Below are some common conditions treated through laser resurfacing:

• Acne Scars: These are permanently indented marks left on the skin after acne lesions heal. Laser resurfacing focuses on smoothing the skin and promoting collagen formation to help treat acne scars.
• Fine Lines and Wrinkles: These are the early signs of ageing, characterised by creases and folds in the skin. Lasers stimulate collagen and elastin production, which helps to restore skin elasticity and reduce these lines.
• Pigmentation Issues: These include conditions such as age spots, sun spots, or melasma, where the skin tone becomes uneven due to excess melanin. Laser therapy targets pigmented areas, breaking down excess melanin and evening skin tone.
• Hair Removal: Laser therapy can effectively treat unwanted hair on various body parts. The laser targets and destroys hair follicles, preventing future hair growth.
• Tattoo Removal: Lasers can break down the ink particles in tattoos, allowing them to be absorbed and eliminated by the body over time. This is a precise method to fade and eventually remove unwanted tattoos.

Side Effects of Laser Treatment

While laser treatments are generally safe and effective, they can sometimes result in side effects. The most common side effects include redness, swelling, and changes in pigmentation. These effects are usually temporary and may subside within a few days to weeks.

However, taking preventive measures to mitigate these risks and ensure optimal results is crucial.

• Redness and Swelling: These are typical post-treatment reactions due to the skin’s response to the laser. Applying a cold compress immediately after the procedure can help reduce inflammation. As a healthcare professional recommends, anti-inflammatory creams or gentle moisturisers can soothe the skin and promote healing.
• Pigmentation Changes: Temporary hyperpigmentation (darkening of the skin) or hyperpigmentation (lightening) can occur in some individuals, especially those with darker skin tones. Avoiding sun exposure before and after treatment is essential to minimise the risk. Applying sunscreen with a high SPF level can protect the skin from UV rays and help maintain an even skin tone.

Who is Suitable for Laser Treatment

Laser treatments can benefit individuals looking to address specific skin concerns like acne scars, fine lines, wrinkles, or pigmentation disorders, as laser therapy effectively targets these conditions. Suitable candidates should be in good health without underlying conditions that could affect healing or increase risks. They must have realistic expectations and understand laser treatments’ potential results and limitations. Committing to aftercare is crucial for ensuring ideal outcomes and minimising side effects.

While laser treatments are effective for many, some should exercise caution or avoid them. Pregnant or nursing women are advised against such procedures due to limited research on effects during these times. Individuals with active skin infections should delay treatment until resolved to avoid worsening the issue. Those with very dark skin or specific pigmentation issues may risk pigmentation changes and should consult an aesthetic practitioner.

Patients taking medications, especially those affecting the skin or causing photosensitivity, should disclose their medications to a healthcare provider before undergoing laser therapy to reduce adverse effects.

How to Choose the Right Laser Treatment

When selecting the right laser treatment, it’s essential to consider your skin type, specific condition, and treatment goals. Dr Boey recommends the following approach:

1. Consult a Professional: Consult a qualified aesthetic practitioner or certified laser specialist like Dr Justin Boey. They can assess your skin type, understand your concerns, and recommend suitable treatment options.
2. Understand Your Skin Type: Different skin types react differently to laser treatments. For instance, individuals with lighter skin tones may handle most laser treatments well. In comparison, those with darker skin tones should opt for systems designed to minimise the risk of pigmentation changes.
3. Identify Your Condition: Targeted issues like acne scars, pigmentation, or wrinkle reduction require specific laser technologies. Ensure the laser treatment is explicitly tailored to address your skin concerns for optimal results.
4. Set Realistic Goals: Clearly define what you hope to achieve through laser therapy. Discuss these goals with your practitioner to align expectations with achievable outcomes, whether complete hair removal, significant scar reduction, or a glowing complexion.
5. Research Treatment Options: Familiarise yourself with the different laser treatments available and their specific uses. Knowing ablative, non-ablative, or fractional lasers will help you understand the best choice for your needs.
6. Consider Aftercare and Downtime: Evaluate the post-treatment care requirements and anticipated recovery time. Some treatments may necessitate more extended downtime and intensive care; ensure you can commit to the necessary follow-up care to maximise benefits and minimise risks.

Laser Treatment Aftercare

After undergoing a laser treatment, following a comprehensive aftercare routine is important to ensure proper healing and maximise the results. Here are some essential steps and considerations for post-treatment care:

1. Keep the area Clean: Clean the treated area with a mild cleanser and lukewarm water twice daily. Avoid using hot water, harsh soaps, or scrubbing the skin, as this can irritate and delay healing.
2. Moisturise: Apply a gentle, fragrance-free moisturiser your practitioner recommends to keep the skin hydrated and facilitate healing.
3. Avoid Sun Exposure: Protect the treated area from direct sunlight by wearing a broad-spectrum sunscreen with high SPF daily. Consider wearing a wide-brimmed hat or clothing to shield the skin further.
4. Cold Compress: If you experience swelling or discomfort, a cold compress wrapped in a soft cloth can help soothe the area and reduce inflammation.
5. Follow Practitioner Guidelines: Adhere to any specific post-treatment instructions your healthcare provider offers, including any ointments or creams to be applied.
6. Avoid Makeup: Refrain from using makeup on the treated area for at least a few days following the procedure, or until your practitioner permits, to allow the skin to breathe and recover.
7. Hydrate and Nourish: Drink plenty of water and maintain a balanced diet rich in vitamins and minerals to support skin regeneration from the inside out.
8. Avoid Strenuous Activity: Steer clear of intense physical activities, saunas, and hot baths that cause excessive sweating, exacerbating sensitivity and irritation.
