Smooth Skin Ahead: Laser Therapy for Stretch Marks

Stretch marks, formally known as striae distensae, are reddish or silvery lines that can appear on various areas of the body. While harmless, they can leave you feeling self-conscious about your skin tone and appearance. And most frustratingly, they don’t disappear with diet or exercise.

Thankfully, there’s a solution–laser therapy. New advancements in laser technology employ fast bursts of light to break up stretch marks and promote the growth of healthy, smooth skin in their place. Here’s how it works.

What Causes Stretch Marks?

Stretch marks form when the dermis, the middle layer of your skin, experiences rapid stretching. This stretching can happen due to various reasons, including:

  • Rapid weight gain: Rapid weight loss or gain puts stress on the skin, leading to tears in the dermis.
  • Pregnancy: As the baby grows, the mother’s abdomen stretches, causing stretch marks.
  • Growth spurts: During puberty, rapid growth can cause stretch marks, particularly on the thighs, breasts and hips.
  • Bodybuilding: Rapid muscle gain can also lead to stretch mark formation.

Stretch marks typically appear red or purple (striae rubra) when they’re new. Over time, they fade to a silvery white color (striae alba). While they may not pose a health concern, they can impact your confidence and self-esteem.

Laser Therapy for Stretch Marks: A Promising Approach

Laser therapy is a minimally invasive, effective treatment option for stretch marks. Laser energy penetrates the skin while causing minimal damage to the epidermis, the surface layer, and stimulates the production of collagen and elastin, the building blocks of healthy skin. This deep rejuvenation plumps up the dermis, improving the texture and reducing the visibility of stretch marks.

Types of Lasers Used for Stretch Marks

Laser therapy for stretch marks utilizes various technologies, each with a unique mechanism of action and suited for different kinds of stretch marks.

Fractional lasers

Fractional lasers, such as the Fraxel laser, can effectively improve the texture, color and shape of stretch marks. They create tiny microthermal zones (like microscopic wounds) within the affected skin. This process stimulates the body’s natural healing process, promoting the growth of new, healthy skin cells and increasing collagen and elastin production in the dermal layer. The surrounding untreated areas facilitate rapid healing.

Non-ablative lasers

Non-ablative lasers work by heating up the dermis without damaging the surface of the skin. This heat stimulates collagen and elastin production, helping to repair and rejuvenate the skin from within.

These lasers are suitable for treating newer stretch marks and are less invasive than ablative lasers. They typically require less downtime but may need multiple sessions for optimal results.

Ablative lasers

Ablative lasers such as the CO2 laser remove the outer layer of the skin, the epidermis, while simultaneously heating the underlying skin (dermis). As the epidermis heals and regrows, the skin appears smoother and more even-toned.

Most commonly known as laser resurfacing, ablative laser treatments are more aggressive than other lasers. They’re effective on older, more established stretch marks as they can remove the stretch mark itself and stimulate new collagen growth. However, they come with a longer recovery time and higher risk of side effects compared to non-ablative lasers.

Pulsed-dye lasers

Pulsed-dye lasers target the blood vessels within the stretch marks. They reduce redness by emitting a concentrated beam of light that is absorbed by blood vessels, damaging them and causing them to be absorbed by the body.

This type of laser is most effective at reducing redness and improving the color of stretch marks to blend more with the surrounding skin.

Which laser is right for me?

Deciding on the best treatment for your stretch marks involves a careful consideration of your specific skin concerns, the type and age of your stretch marks and your desired outcomes. Consulting with a dermatology specialist such as a dermatologist, plastic surgeon or licensed laser technician can provide you with tailored advice and a treatment plan that aligns with your goals.

What to Expect at Your Laser Stretch Mark Removal Appointment

Here’s a breakdown of the laser treatment process for stretch marks:

Consultation

During a consultation with a qualified dermatologist, your stretch marks will be assessed. The dermatologist will discuss your goals, medical history and recommend the most suitable laser and treatment plan based on the severity, color and location of the stretch marks.

Treatment 

During your laser procedure, a numbing cream may first be applied to the treatment area to minimize discomfort. Then, your provider will use the laser to deliver targeted energy pulses to the skin. 

The number of treatment sessions needed depends on the severity of your stretch marks and the desired outcome. Typically, multiple sessions spaced several weeks apart are recommended for optimal results.

Downtime and healing

Laser treatment for stretch marks is minimally invasive with minimal downtime. You may experience some redness or swelling after the procedure, which usually resolves within a few days. 

Proper post-treatment care, including diligent sun protection, is key for optimal healing and to prevent hyperpigmentation (darkening of the treated area). Keep the treated area clean and moisturized, and avoid using harsh products or picking at the treated area as it heals.

Results

Once your skin has fully healed, the targeted stretch marks will be less noticeable and blend more smoothly with the surrounding skin. While laser treatments can greatly improve the appearance of stretch marks, it’s important to note that they may not completely erase them. 

Safety and Side Effects of Laser Stretch Mark Removal

This procedure is generally safe when performed by a qualified professional with experience in laser skin resurfacing. However, as with any medical procedure, there are some potential side effects to consider, including:

  • Temporary redness or swelling: These are the most common side effects and typically subside within a few days after treatment.
  • Hyperpigmentation: In some cases, the treated area may become darker than the surrounding skin. This risk is higher for individuals with darker skin tones and can be minimized with consistent use of sunscreen following treatment.
  • Hypopigmentation: Rarely, the treated area may become lighter than the surrounding skin. This is more likely with aggressive laser treatments and in individuals with darker skin tones.
  • Scarring: Scarring is a rare complication but can occur if the laser treatment is too aggressive or if the skin doesn’t heal properly.

Am I a Good Candidate for Laser Stretch Mark Treatments?

Laser therapy offers a promising and effective approach for improving the appearance of stretch marks. However, it’s not always the best option for everyone. Here are some factors to consider when deciding if laser therapy is right for you:

Severity of stretch marks

Laser therapy is generally more effective for newer, red stretch marks. White stretch marks may require a combination of treatments, such as fractional laser therapy combined with microneedling or chemical peels, for optimal results.

Skin type

People with darker skin tones are at a higher risk of hyperpigmentation following laser treatment. A consultation with a dermatologist experienced in treating various skin types is key to determine if laser therapy is safe and suitable for you.

Medical history

Certain medical conditions or medications may make you a poor candidate for laser therapy. Be upfront with your dermatologist about your medical history during the consultation.

Cost

Laser stretch mark removal can be expensive, and insurance typically doesn’t cover it as it’s considered a cosmetic procedure. Be sure to discuss the cost of treatment with your dermatologist before starting the process.

How Do I Prevent Stretch Marks?

Preventing stretch marks, though not always entirely possible, involves several proactive measures that can significantly reduce their likelihood and severity. Some strategies to keep in mind are:

  • Maintain a Healthy Weight: Fluctuations in weight, especially rapid gains or losses, can stretch the skin and lead to stretch marks. Aim for a steady and healthy weight through balanced nutrition and regular exercise.  
  • Stay Hydrated: Adequate hydration keeps your skin soft and less prone to stretch marks. Drinking enough water and moisturizing your skin can maintain its elasticity and reduce the chances of stretch marks forming.
  • Eat a Nutrient-Rich Diet: A diet high in vitamins and minerals, particularly vitamins C and E, zinc and silica, can help maintain skin health and elasticity. Foods like citrus fruits, nuts, seeds and leafy greens are excellent choices.
  • Use Preventive Lotions and Oils: Specially formulated creams and oils can increase skin elasticity when applied during pregnancy or periods of significant weight gain. Ingredients like hyaluronic acid, vitamin E and gotu kola extract may be particularly beneficial.
  • Avoid Steroid Creams: Prolonged use of topical steroid creams can weaken skin structure and increase the risk of stretch marks. Use such medications only as prescribed by a healthcare professional.
  • Manage Sun Exposure: Protect your skin from excessive sun exposure, which can deplete its moisture and reduce its elasticity, making it more susceptible to stretch marks. Use sunscreen and seek shade when necessary.

While these preventive measures can be effective, it’s important to acknowledge that genetics also play a significant role in the development of stretch marks. If you’re predisposed to them or if they’ve already developed, laser therapy or other treatment options can be an effective treatment option.

The Bottom Line: Taking Charge of Your Skin Health

Stretch marks are a common concern, but they don’t have to define you. With various treatment options available, including laser therapy, you can achieve smoother, more confident skin.  Remember, the best course of action depends on the severity and color of your stretch marks, your skin type and your overall health. Consulting with a qualified dermatologist or other provider can help you discover the most suitable treatment plan to achieve your desired results and feel comfortable and confident in your skin.
