I’m seeing a real difference in my stretch marks
I’ve been having laser treatment for my stretch marks and I’m seeing a real improvement. I feel like a few more sessions might make them much harder to see. The treated skin also feels softer!!!
Our stretch mark program combines scar lasers, skin-tightening treatments, growth factors and a protective skin dressing. The combination depends on how long the marks have been present and on your skin’s firmness, and it addresses both color and texture.

One treatment alone has its limits. We assess the age of your stretch marks and your skin’s firmness before choosing a combination.

Scarring, firmness,
color and repair:
one coordinated treatment plan

Stretch marks develop when collagen and elastin in the dermis are damaged and altered. A single treatment may have limited effects, so we combine approaches according to the age of the marks and the firmness of the skin.
Our program addresses scarring, firmness, color and repair together. Scar lasers and skin-tightening devices stimulate the dermis, BENEV growth factors support recovery, and Shin Nanoskin provides a protective covering during healing.

Scar lasers stimulate collagen and elastin in the damaged dermis, helping stretch marks become narrower and shallower.

Treatments such as body Thermage and plasma support collagen and elastin renewal, improving loose skin around stretch marks.

Laser treatment and growth factors support repair, helping red or white stretch marks blend more closely with the surrounding skin.

As the dermis renews itself, Shin Nanoskin helps retain moisture so rough skin can feel smoother and softer.

Areas such as the abdomen, thighs, buttocks and upper arms can be treated in one session. The larger body Thermage tip delivers energy across a broad area of skin and underlying tissue.

BENEV growth factors support recovery, while Shin Nanoskin helps prevent moisture loss and soothe treated skin.
Treatment planning and technique both affect results. At Dong-An Joongsim Clinic, a doctor conducts your consultation and performs your treatment, with time to assess your individual concerns.
Your doctor chooses the devices and energy settings from a range of eight systems, including Legato II, UltraPulse, DeepPulse, Harmony XL4D-1, 1540XD and body Thermage. We have also added the 1565 nm ResurFX laser.
We coordinate treatment for scarring, firmness, color and repair so that each approach supports the others.

The stretch marks on my calves stand out less
I tried treatment for stretch marks on my calves that had been there since my teenage years. It still hurt despite the anesthesia, and there were red marks afterward. As they healed, the stretch marks looked less noticeable, though I can still see some up close. I see it as an improvement rather than a complete fix.
The lines are less noticeable
I hesitated because the stretch marks on my calves were so old. What I remember most after treatment is waiting for the redness to settle. It hurt on the day, and the marks were quite vivid, but over time the lines became less noticeable. I saw the biggest difference from a distance.
My stretch marks bother me less now
The cost and discomfort made me think carefully before deciding. After treatment on my calves, I had to wait for the red marks to heal. As they faded, my stretch marks started to bother me less. Some are still there, but they catch my eye less than before, which I’m pleased about.

These four common types differ in their causes and typical locations.
| Type | Features |
|---|---|
| Adolescent stretch marks | Often on the calves, thighs, buttocks and lower back; adrenal hormones play a role |
| Pregnancy-related stretch marks | Affect around 90% of pregnant women |
| Medication-related stretch marks | Associated with steroid use; often wider and deeper |
| Weight-related stretch marks | Rapid weight gain can cause marks on the buttocks, thighs and abdomen |
How do stretch marks fade? Treatment follows four steps. A doctor who teaches stretch mark treatment internationally plans the combination according to the age of the marks and your skin’s firmness.

We examine their type, age and the firmness of the surrounding skin.
Scar lasers and tightening devices stimulate repair in the damaged dermis.
BENEV growth factors support skin renewal and wound healing.
Shin Nanoskin covers the treated area to support a moist healing environment.

Our approach
Dr. Soyoun Koo introduced the clinic’s stretch mark program and clinical cases on Korea Economic TV’s “WOW Medical Center.” Dr. Cho discussed developments in devices and treatment approaches in the November 2018 issue of D&PS.

Our doctors explain concerns related to stretch marks in plain language.

Red stretch marks are an early stage with visible vessels and inflammation. White stretch marks are a later stage of thinned, scarred dermis, so treatment differs.
The doctors at Dong-An Joongsim Clinic
To reduce the appearance of enlarged pores, first identify the cause: excess oil, loss of firmness or the size of the hair follicles.
The doctors at Dong-An Joongsim Clinic
Depressed acne scars fall into three main types: ice pick, rolling and boxcar. Each responds to a different combination of lasers and other treatments.
The doctors at Dong-An Joongsim ClinicThe plan and the doctor’s technique both matter. Check who conducts the consultation and treatment, whether authentic devices and supplies are used, and whether treatments can be combined to suit your skin. At Dong-An Joongsim Clinic, your consultation and procedure are both handled by a doctor, with time to discuss your individual needs.
They can develop during pregnancy, weight gain, adolescent growth or steroid use. They often begin as red lines, gradually become white, and may appear symmetrically on both sides of the body.
Stretch marks involve damage to dermal collagen and elastin, so creams alone have limited effects. Laser treatment stimulates repair, aiming to reduce their width and depth and help their color blend with surrounding skin. Our program combines scar lasers, tightening treatments, growth factors and Shin Nanoskin according to the condition of your skin.
Red stretch marks gradually turn white. Older white marks can also be treated with scar lasers and growth factors to improve their texture and color. Patients have reported that their stretch marks became less noticeable and the treated skin felt softer.
Yes. Men may develop stretch marks on the arms, flanks or thighs during growth, rapid weight changes or muscle gain. The underlying process is the same. We choose a combination based on how long the marks have been present and the skin’s firmness.
As redness and bruising settle over 1–2 weeks, smoother texture may be the first change you notice. With dermal renewal and repeated sessions, stretch marks can become narrower and lighter.
Cost depends on the location and size of the area, the combination of devices and the number of sessions. Your doctor assesses your stretch marks and explains the proposed plan and cost.
Because stretch marks involve damaged collagen and elastin, one approach alone has limitations. Addressing scarring, firmness, color and repair together can improve the overall result.
We treat stretch marks on the abdomen, thighs, buttocks, arms and calves. For larger areas, we may include body Thermage with its larger treatment tip.
Redness, bruising and reduced sensation may occur, usually settling within 1–2 weeks. Temporary firmness or a cool sensation can also occur immediately afterward.
The 1565 nm ResurFX laser is nonablative and fractional: it delivers microscopic zones of heat to the dermis without removing the skin’s surface. This stimulates collagen renewal, while contact cooling helps keep the skin comfortable. Coverage and density are adjusted to the depth and width of the marks and your skin’s condition.
After childbirth, the abdomen may change because of fat, loose skin and stretch marks together. Reducing fat and treating stretch marks in the dermis are different goals, so we assess each cause and plan treatments accordingly. Timing also depends on your recovery after childbirth and whether you are breastfeeding.
