Spots, Scars, and Stretch Marks: Lasers Can Treat Them All

Skin imperfections can damage your self-confidence and prevent you from looking as good as you feel. Spots, scars, and stretch marks represent some of the most common flaws that can make you feel self-conscious and less than your best. While makeup and clothing can help camouflage these imperfections, lasers are a better option.

You’ll experience the best outcomes from laser therapy when you work with our professionals who specialize in this area of cosmetic procedures. Cosmetic and reconstructive surgeon Dr. Allan Wu and our clinical team at MedWeight, Lasers & Wellness Centers offer customized laser therapy services that can help you achieve your desired results. Dr. Wu and the staff administer cutting-edge treatments with an eye for aesthetics to ensure that your results appear natural.

Here’s how our lasers can treat some of the most common skin imperfections -- spots, scars, and stretch marks.


Age spots, often called liver spots, appear as light brown flat spots. They can grow anywhere on your body but can be most noticeable on your face, neck, and hands. While age spots are associated with aging, many of these spots occur as a result of sun exposure or other sources of ultraviolet light such as tanning beds.

Treating age spots requires a dermatological evaluation to ensure that the spots aren’t related to skin cancer. If there’s a concern, you may require a skin biopsy, which involves taking a sample of your skin for microscopic analysis. 

Laser therapy works by destroying melanin-producing cells, which cause the brown color, without damaging the skin’s surface. A professionally trained provider can deliver treatment while reducing the possibility of skin discoloration. 

Depending on the color, size, and depth of your age spots, you may require more than one treatment session to achieve your desired results. After laser treatment, you may experience some redness, so subsequent treatments are spaced apart to allow for healing. 

Your spots disappear gradually over several weeks or months. As you heal, it’s important to protect yourself from the sun to avoid damaging the fresh skin. 


Scars are made up of cells and collagen that cover the site of an injury, surgery, or acne. Laser therapy helps encourage the growth of healthy skin by removing damaged skin and stimulating collagen production so new skin can grow in its place. 

The effect of laser therapy can make a scar less visible, but it doesn’t remove it. In effect, the treatment replaces your noticeable scar with one that’s less noticeable.

In addition to providing cosmetic benefits, laser treatment for scars can:

After receiving laser therapy for a scar, you may experience pinkness or redness for up to eight hours. You may also feel like you have a mild sunburn in the treated area, and have mild swelling that lasts for several days. Results can take months to appear, with improvement occurring gradually over time. 

Stretch marks

Stretch marks appear when your skin stretches or shrinks quickly. The collagen and elastin that support your skin rupture in response to the sudden change, and stretch marks appear as the skin heals. 

Stretch marks looks like narrow bands, stripes, or lines. Their appearance varies relative to their age, cause, location, and your skin type. While stretch marks can become less noticeable over time, they won’t disappear on their own. 

Laser therapy for stretch marks helps to stimulate the growth of collagen to help make stretch marks smoother and reduce their appearance. Depending on the condition of your stretch marks, you may require more than one session. 

Like other laser treatments, post-treatment pink or red skin can result. Depending on the area treated, your skin may feel raw and uncomfortable for a short time, and the improvements in the appearance of your stretch marks develop over several months.
