Patients come to me asking which treatment works best for stretch marks. My answer is always the same: it depends on the stretch mark. Laser treatment is being the most effective treatment Starting with an accurate assessment of the skin factors such as colour, depth, age, and location all influence which technology I recommend. At REPIC Clinic in Seoul, I use these clinical findings to guide treatment selection rather than relying on a one-size-fits-all approach.

The Factors We Consider Before Recommending a Stretch Mark Laser

Stretch marks are a normal part of life that can develop to anyone. Mostly it occurs in periods of growth, pregnancy, weight changes, or hormonal fluctuations, and they affect individuals of all ages and skin types.

Stretch marks are not a medical concern, but people choose to go toward treatment options to improve their skin. Questions like which laser treatment is best is mostly depends on several factors, including the type of stretch mark, how long it has been present, and the characteristics of the surrounding skin.

Before I recommend any treatment, I focus on understanding these factors first to help and  ensure that the chosen treatment is appropriate for the skin condition. Today I’ll be giving you an overview of my process.

How Stretch Marks Form

Stretch marks occur due to rapid weight changes, hormonal fluctuations, genetics, and steroid use.

When the skin stretches suddenly, collagen and elastin fibers in the dermis are damaged, causing visible lines.

They are most common during pregnancy and adolescence because cortisol levels rise, which breaks down collagen fibers.

Types of Stretch Marks

Not all stretch marks look the same. Depending on how long they have been present and the changes occurring within the skin, they can generally be divided into two categories.

1. Red Stretch Marks (Striae Rubrae)

• Early stage: red or purple lines on the abdomen, thighs, or buttocks

• Features: vascular dilation, inflammatory cell infiltration, edema

• Dermis begins extracellular matrix remodeling

2. White Stretch Marks (Striae Albae)

• Later stage: white or silver-colored, slightly indented lines

• Features: decreased inflammation, parallel collagen fibers, reduced elastic fibers, epidermal thinning

• Reduced melanocyte activity makes them appear lighter than surrounding skin

Laser Treatments by Stretch Mark Type

Red Stretch Marks (Striae Rubrae):

• Use vascular lasers like Clarity

• Targets abnormal blood vessels

• Stimulates collagen regeneration

• Early treatment is most effective

White Stretch Marks (Striae Albae):

• More challenging and requires longer treatment duration

• Use fractional lasers like Fraxel or CureJet

• Similar to scar treatment, micro-injuries promote collagen formation

• Heats deep dermis for tissue regeneration and smooths uneven skin surface

• Side effects may include redness, crusting, and mild pain

CureJet Device:

• Needle-free injection system that delivers pressure to stimulate collagen

• Minimal pain and fewer side effects compared to traditional lasers

• Can be combined with skin boosters like Rejuran or Juvederm Volume for enhanced results

Key Points for Stretch Mark Laser Treatment

Different stretch mark types require different lasers.

Treatment approach depends on:

• Type and stage of the stretch mark (red or white)

• Age of the stretch mark

• Size and severity

• Skin thickness and treatment area

• Individual skin characteristics and treatment goals

⚠️ Avoid using skin-colored tattoos to cover stretch marks, they may darken over time and are difficult to remove.

⚠ I generally advise against skin-coloured tattoos for stretch marks, as they can darken and complicate future treatment options.

Stretch Mark Laser Treatment Simplified

There is no single laser option that works best for every stretch mark. The most effective treatment strategy depends on factors such as the stage of the stretch mark, skin characteristics, and treatment objectives. At REPIC Clinic in Gangnam, Seoul, treatment recommendations are based on these individual factors rather than a one-size-fits-all approach.
