Types of Stretch Marks: How to Tell Which Ones You Have

What the types of stretch marks mean: colour stage, cause label, three checks to tell new from old, and how marks read on deeper skin tones.

Types of stretch marks carry two labels at once: a colour stage and a cause. Striae rubra are new red or purple marks, striae alba are the faded white or silver stage, and cause labels such as striae atrophicans name what stretched the skin. Reading both labels tells you how old a mark is and what to expect next.

The types of stretch marks are two labels, read together

Almost every guide presents one flat list that mixes Latin colour words with Latin cause words, which is why readers finish the page unsure which one applies to them. The clearer way to hold it: every mark carries a colour label and a cause label at once.A pink line on a pregnant belly sits in the red stage and carries the pregnancy cause label. Eighteen months later the same line has moved to the pale stage, and the cause label has not changed.

The umbrella term for the whole group is striae distensae, which translates roughly as stretch lines. Clinicians also shorten it to skin striae in notes and consultation letters. The mechanism underneath is the same in every case: the dermis is pulled faster than it can produce collagen and elastin, the fibres tear, and the repair fills the gap with scar tissue that reflects light differently from the skin around it.

Axis Label What it describes
Colour stage Striae rubra New. Red, pink or purple, sometimes slightly raised and itchy.
Colour stage Striae alba Mature. White, silver or pale, usually a little sunken.
Colour stage Striae nigra, striae caerulea Dark brown to black, or blue to slate grey. Seen mostly on deeper skin tones.
Cause Striae gravidarum Pregnancy.
Cause Striae atrophicans Thinned skin, often from long steroid use or a condition such as Cushing’s syndrome.
Cause Striae distensae The umbrella label for marks from rapid stretching of any kind.

Read the table down the Axis column rather than across it, and the confusion clears: nobody carries a colour label instead of a cause label, they carry one of each.

Striae rubra: the red, pink and purple stage

Striae rubra, sometimes written with the Latin plural ending, is the name for a mark in its first months. The colour is not pigment. It comes from blood vessels sitting closer to the surface than usual, because the dermis above them has thinned where the fibres gave way. That is why red stretch marks often look brighter after a hot shower or a gym session, and duller first thing in the morning.

Two other signs travel with this stage. The American Academy of Dermatology describes marks at this point as slightly raised and sometimes itchy, and plenty of people register the itch before they register a line. The itch signals skin under mechanical strain rather than anything going wrong.

This stage also carries the practical point that most treatment guides bury. While the vessels are still active, the tissue is still remodelling, and published reviews consistently find better response to treatment at this point than later. That is the reasoning behind clinics steering early marks toward gentler options such as a topical retinoid or a course of microneedling before anything more aggressive is discussed.

Striae alba: the white, silver and grey stage

Striae alba is the mature form. The vessels calm down, the redness drains away, and what remains is a strip of scar tissue with less pigment than the skin around it. On lighter skin that reads as white or silver. On medium and deeper skin it more often reads as pale grey, ash or a dull sand colour against the surrounding tone.

Texture changes too. As the scar contracts, white stretch marks tend to sit slightly below the surface, so they catch shadow in raking light and can look creased or wrinkled. Old marks frequently become more visible with age, not less, because the surrounding skin loses elasticity while the scar does not change. Options aimed at this stage, such as fractional laser skin resurfacing, work on texture and tone rather than on colour, since there is no longer a red component to settle.

New versus old stretch marks: three checks you can run at home

The most common question about stretch marks colour stages has no picture that reliably answers it, because the same stage looks different on every skin tone. Three physical checks work better than a photo comparison, and none of them needs equipment.

  1. Press it. Colour that comes from blood vessels lightens under gentle finger pressure and floods back when you let go. Colour that comes from scar tissue does not move. A mark that pales under the finger is still in the rubra stage whatever shade it looks in the mirror.
  2. Feel across it, not along it. Run a fingertip at right angles to the line. A newer mark sits level or a fraction raised. A mature one usually drops into a shallow groove you can feel before you can see.
  3. Notice the itch. Itching and tightness cluster around the forming stage and settle as the mark matures. A line that has stopped itching has generally stopped changing quickly.

These checks date a mark. They say nothing about what caused it, and they are not a diagnosis. Anything that is spreading fast, appearing without an obvious trigger, or arriving alongside other skin or weight changes belongs in front of a licensed clinician rather than a search bar.

The press test is most useful in the first year. After that both stages behave the same under pressure, and texture becomes the more reliable signal.

The cause labels: pregnancy, steroids and everything else

Cause labels answer a different question: what pulled the skin. They do not describe how a mark looks today.

Striae gravidarum is the pregnancy form. Marks usually surface in the second and third trimesters across the lower abdomen, breasts, hips and thighs, and they follow the same ageing path as any other mark: red or dark first, pale later. Worth separating from linea nigra, the vertical brown line that appears down the centre of the abdomen in pregnancy. That is pigmentation, not a scar, it is not a stretch mark, and it usually fades on its own after birth.

Striae atrophicans describes marks on skin that has been thinned from the inside, most often by long term topical or oral corticosteroids, or by a hormonal condition such as Cushing’s syndrome. The tell is distribution: these turn up in places under no real mechanical strain, and that pattern is a reason to raise it with a doctor rather than a beauty therapist.

Striae distensae is the catch-all for everything driven by ordinary rapid stretching: a puberty growth spurt, weight gain or loss, or muscle put on quickly through training. Most marks on most people sit here.

What do stretch marks look like on brown and deep skin tones?

The standard red-to-white description was written for light skin, and it misleads a large share of Dubai’s population. On Fitzpatrick types IV to VI, a new mark is more likely to read purple, deep brown or near black than red, and a mature one is more likely to read grey, ash or hypopigmented than white. The two labels that cover this are striae nigra for the dark brown to black form and striae caerulea for the blue to slate version.

The practical consequence is that a reader with deeper skin who is looking for red stretch marks may decide they do not have new marks at all, and miss the window where marks respond best. Run the press test instead of matching a colour swatch. It is also why treatment decisions on deeper skin get made more cautiously: several devices that suit lighter skin carry a real risk of leaving a pigment change behind, which is the same caution that governs hyperpigmentation treatment generally.

Where each type shows up on the body

Location is the other clue people use, and it is a reasonable one, because the trigger decides where the skin gets pulled hardest.

Trigger Where marks usually appear Label most often used
Pregnancy Lower abdomen, breasts, hips, thighs Striae gravidarum
Rapid weight gain Abdomen, hips, outer thighs, upper arms Striae distensae
Puberty growth spurt Outer thighs, lower back, calves, breasts Striae distensae
Muscle gain from training Shoulders, chest, upper arms Striae distensae
Long term steroid use Widespread, including low strain areas Striae atrophicans

The distinction people most often ask about, gaining against losing weight, is largely a false one: the marks form while the skin is being stretched, then become easier to see once the volume underneath drops away.

Which stretch marks are permanent?

All of them. Every stretch mark is a dermal scar, and a scar does not leave. What changes is how visible it is: the red settles, the contrast drops, and a mark that dominated the skin at six months can be hard to find at three years without anyone doing anything to it.

That distinction matters when reading treatment claims. Nothing available returns skin to an unmarked state, and the NHS puts it plainly: marks usually fade over time but may not disappear completely. What clinical work realistically buys is a reduction in colour, depth and texture, with the strongest results on marks caught in the rubra stage. Anyone weighing that up will find the method by method breakdown in the guide to stretch marks treatment in Dubai more useful than another before and after gallery.

Where to get skin striae assessed in Dubai

Identifying a mark at home is enough for most people, since most marks need nothing done to them. An in person look earns its fee when marks appear without a clear trigger, spread quickly, or when someone wants a realistic read on what treatment would achieve before paying for a course.

Two licences matter in the UAE and they are not interchangeable. Any salon or clinic trading in Dubai holds a Department of Economy and Tourism (DET) trade licence, which covers the business but says nothing about clinical scope. Assessment or treatment of a skin condition additionally requires Dubai Health Authority (DHA) licensing, held by both the facility and the individual practitioner. A venue offering a device-based stretch mark treatment without DHA clinical licensing is working outside its permission, and the licence is a fair thing to ask to see. The directory currently lists 17 aesthetic clinics alongside its skin specialists and aesthetic salons categories, and the ranking methodology explains how entries are ordered.

One thing worth doing before that appointment: run the press test and note which lines still lighten under the finger. Those are the ones where a conversation about texture and tone work, a chemical peel or something more targeted, has the most to work with. The pale ones set a different expectation entirely. Knowing which is which before walking in is what keeps a consultation from turning into a sales pitch.

Frequently asked questions

Six named forms cover almost everything: striae rubra, striae alba, striae nigra and striae caerulea describe the colour stage, while striae gravidarum and striae atrophicans describe the cause. Striae distensae is the umbrella term for the whole group.

Raised or level lines running across the direction the skin was pulled, in red, pink or purple on lighter skin and purple, deep brown or near black on deeper skin. They often itch before they are visible.

Red ones. While a mark is still in the vascular red stage the tissue is actively remodelling and responds better to treatment. Once it turns pale the work shifts to texture and tone, and results are more modest.

All of them. Every mark is a dermal scar and the scar itself stays. Visibility drops a lot over the first two to three years, and treatment can reduce colour and depth further, but no method removes a mark completely.

Normal, and not a health problem. They are one of the most common skin findings there is, they are not contagious, and they need no treatment. Marks that appear with no obvious trigger are the one exception worth checking.

Press one. Colour from blood vessels lightens under the finger and returns; scar colour does not move. Newer marks also sit level or slightly raised and may itch, while older ones sit in a shallow groove.

Striae distensae covers marks from rapid stretching of any kind. The pregnancy label names the subset caused by carrying a child, so a pregnancy mark is both at the same time.

Yes. Every mark starts in a vascular red or dark phase and fades to a pale one over months to years. The two stretch marks colour stages are the same line at different ages, not two different problems.
