Red and White Stretch Marks After Childbirth: What Can MiraJet Do?

Why do stretch marks appear after childbirth?

During pregnancy, the skin of the abdomen, breasts, buttocks and thighs stretches greatly in a short time. When the dermal structure cannot keep up with the speed of stretching, collagen and elastic fibers are damaged and long linear stretch marks can appear. Besides pregnancy, rapid weight gain, growth spurts, increased muscle mass and hormonal changes can also cause stretch marks. Stretch marks are not white from the start. Early on they appear red or purple as striae rubra, and over time they gradually fade into striae alba, lighter than the surrounding skin. Older stretch marks can also show texture change, with thin, slightly sunken skin. That is why red and white stretch marks are not managed the same way, even though both are "stretch marks."

How are red and white stretch marks different?

Red stretch marks

Red stretch marks are a relatively early stage. They are red or purple and clearly differ in color from the surrounding skin. Because vascular changes remain, treatments that improve color can be used along with treatments that stimulate skin regeneration. Especially for recent postpartum stretch marks, it is better to manage them actively before they progress to older white stretch marks. Studies of stretch-mark treatment also report that red-stage stretch marks tend to respond better than older white ones.

White stretch marks

White stretch marks are a later stage in which color has faded and the dermal structure has changed. They look lighter than the skin, and the skin along the line can become thin or slightly sunken. Because the dermal change is already established, whitening or moisturizing alone cannot improve the sunken texture. So for white stretch marks, it is realistic to aim to reduce the texture, depth and color contrast rather than return the color completely to normal skin.

In a systematic review of 151 studies (4,806 cases) on stretch-mark treatment, complete resolution was rare and red stretch marks tended to respond better. The researchers concluded that stretch marks vary so much that no single treatment solves them.^[1]

How does MiraJet manage stretch marks?

The MiraJet nozzle uses laser energy of a specific wavelength to generate pressure, and uses that pressure to deliver a solution into the skin as a fine jet. Its key feature is delivering medication needle-free, unlike needle injection. The process, simply put: laser irradiation → instant pressure → microjet ejection → drug delivery into the skin. Because the purpose depends on the medication used, it is not accurate to think of "MiraJet itself as a drug that removes stretch marks." Its advantage lies in precisely delivering the needed medication to target deeper skin layers.

What can MiraJet do for red stretch marks?

Because red stretch marks are relatively recent, it is important to manage both the redness and the texture change. MiraJet treatment can deliver medications aimed at skin regeneration along with fine microjet stimulation, so it can be used to improve the color contrast and texture of stretch marks. Treatments that induce collagen formation focus on improving surface texture and dermal structure. So if red lines have started to appear on your abdomen after childbirth, rather than waiting a long time hoping they will fade, it is better to consider treatment that actively stimulates skin regeneration at an early stage.

Can MiraJet be used for white stretch marks?

Yes. MiraJet can be used for white stretch marks to improve texture and depth. But because white stretch marks usually involve established, older dermal damage, you should not expect the same results as with red ones. The key to treating white stretch marks is less about color change and more about how much the sunken texture can be softened and how much the border with surrounding normal skin can be blended.

Will MiraJet make stretch marks disappear completely?

It is not accurate to call it a treatment that removes them completely. Stretch marks are a scar-like change in which the dermal structure is damaged, so no current treatment can be said with certainty to return every stretch mark to exactly normal skin. Many treatments aim to improve color and texture, but complete removal has limits. MiraJet is no exception. The goal is closer to reducing the color difference, softening the sunken texture and helping the area blend naturally with surrounding skin. Stretch marks are usually approached over several sessions, with skin regeneration accumulating, rather than one treatment completing a big change.

How does the skin change after MiraJet?

Because MiraJet delivers medication with microjets instead of needles, temporary redness, swelling or pinpoint bleeding can appear right after treatment. When used on stretch marks or scars, mild bruising and swelling can last a few days, and small scabs may form and then heal. Clinical data on MiraJet also report that mild bruising and swelling can occur after stretch-mark or scar treatment and generally resolve. So rather than expecting smooth skin right after treatment, allow time for the skin to recover and regenerate. After treatment, it is important to follow the medical team's guidance on moisturizing, sun protection and avoiding irritation. In particular, avoid rubbing the area hard or forcibly removing flaking skin.

When should stretch-mark care start after childbirth?

If red stretch marks have already appeared, it is best to manage them as early as possible. Red stretch marks turn white over time, and in later stages skin atrophy and texture change become more pronounced. However, right after childbirth your body is still recovering, and whether you are breastfeeding can affect the treatment plan. Because MiraJet delivers medication directly into the skin, it is important to check which medication will be used. During pregnancy and breastfeeding there may be restrictions depending on the medication, so you should not assume "it's MiraJet, so I can do it right after childbirth." If you are planning postpartum stretch-mark treatment, it is safer to set the schedule after checking the timing, breastfeeding status and the planned medication.

What matters when getting stretch-mark care at a wellness clinic

Even in the same area, stretch marks can differ in color and depth. For example, widespread red stretch marks on the abdomen after childbirth and deep white stretch marks from years ago are better treated with different goals rather than repeating the same treatment.

Red stretch marks → manage color and early dermal change together

White stretch marks → focus on improving sunken texture and color contrast

An approach matched to the condition is important. At a wellness clinic, stretch marks can be managed by delivering medication into the dermis with MiraJet to stimulate skin regeneration. What matters is not "how many MiraJet sessions until they're gone?" but planning treatment according to the current stage of the stretch marks and the degree of skin damage.
