Stretch marks

Causes of stretch marks

Stretch marks are the result of rapid stretching of the skin due to sudden growth or weight gain.

This stretching causes the middle layer of skin (the dermis) to tear, allowing the deeper skin layers to show through, forming stretch marks.

The dermis contains strong, inter-connected fibres that allow your skin to stretch as your body grows. However, rapid growth can over-stretch and break the fibres.

The tears in the dermis allow the blood vessels below to show through. This is why stretch marks are often red or purple when they first appear.

When the blood vessels eventually contract, the pale-coloured fat underneath your skin will be visible, and your stretch marks will change to a silvery-white colour.

When stretch marks occur

Stretch marks often occur:

  • during pregnancy
  • after rapid weight gain
  • during puberty
  • if you have a family history of stretch marks
  • if you have an underlying health condition or a syndrome, such as Marfan syndrome
  • after the prolonged or inappropriate use of corticosteroid medication  

These are discussed in more detail below.

Pregnancy

Stretch marks are common during the later stages of pregnancy, affecting about 8 out of 10 pregnant women. Whether or not you’ll get stretch marks depends on your skin type and how elastic it is.

During pregnancy, your body produces hormones that soften the ligaments in your pelvis so they’re more flexible when you give birth. Ligaments are strong bands of tissue that connect joints. However, the hormones also soften the fibres in your skin, making you prone to stretch marks.

As your baby grows, you may get stretch marks on your tummy, as your skin stretches. You may also develop stretch marks on your thighs and breasts as they get bigger.

After childbirth, stretch marks usually fade and become less noticeable, but they don’t always disappear completely.

Rapid weight gain

You may get stretch marks if you put on a lot of weight over a short period of time.

The stretch marks sometimes remain even after losing weight, but should eventually fade.

If you diet regularly, stretch marks can occur as your weight goes up and down. Should you need to lose weight, lose it slowly and steadily so that your skin isn’t put under strain.

Read more about how to lose weight safely.

Bodybuilders and athletes can also get stretch marks as their muscles increase in size.

Puberty

During puberty, the body often develops very quickly in growth spurts.

Boys may get stretch marks on their shoulders and back, and girls may get them on their hips, thighs and breasts.

Family history

If you have a close relative with stretch marks, such as your mother, you’re more likely to develop them yourself.

Although stretch marks can affect both male and female members of your family, they’re most common in women.

Underlying health conditions

Stretch marks can sometimes be caused by rare, underlying health conditions or syndromes, such as Cushing’s syndrome and Marfan syndrome.

Cushing’s syndrome occurs when the body overproduces the hormone cortisol, which is thought to cause stretch marks to develop.

Marfan syndrome is caused by a faulty gene that affects your body’s skin and connective tissues. It weakens your body’s tissues, reducing their elasticity (ability to stretch). This means your skin isn’t as resistant to stretch marks as it should be.

If you have Marfan syndrome, you may develop stretch marks on your shoulders, hips or lower back.

Corticosteroids

In rare cases, stretch marks can develop after prolonged or inappropriate use of corticosteroid medicines, such as creams or lotions used to treat skin conditions, including eczema.

Corticosteroids work in a similar way to the hormone cortisol, which is naturally produced by your body.

Corticosteroids can help ease inflammatory skin conditions; however, like cortisol, they can also decrease the amount of collagen in your skin.

Collagen is a protein that helps to keep your skin stretchy. This means that the less collagen there is in your skin, the more likely you are to develop stretch marks.

When using a corticosteroid cream or lotion, make sure you follow the manufacturer’s instructions about how and where to apply it. The face, groin and armpits are particularly sensitive areas. If you’re unsure, ask your GP or pharmacist for advice.

Stretch marks 

Introduction 

Stretch marks that develop during pregnancy are known as striae gravidarum 

Who gets stretch marks?

Stretch marks are very common. Anyone can get them, but they tend to affect women more than men.

About 8 out of 10 women get stretch marks during pregnancy. About 7 out of 10 girls and 4 out of 10 boys get them during puberty.

Look after your skin

Benefit your skin by stopping smoking, plus how to protect your skin against sun damage and more

Stretch marks are narrow streaks or lines that occur on the surface of the skin.

Doctors often refer to stretch marks as stria, striae or  during pregnancy  striae gravidarum.

The tummy (abdomen), buttocks, breasts and thighs are the areas of the body most often affected.

Stretch marks are often red or purple to start with, before gradually fading to a silvery-white colour. They’re usually long and thin.

Read more about the characteristics of stretch marks.

What causes stretch marks?

Stretch marks are the result of the skin suddenly stretching. The middle layer of skin (dermis) breaks in places, allowing the deeper layers to show through.

The dermis can be stretched:

  • during pregnancy
  • as a result of weight gain
  • due to growth spurts during puberty

Read more about the causes of stretch marks.

When to see your GP

See your GP if you have stretch marks that don’t seem to be linked to weight gain or growth, because they may be due to another condition.

In rare cases, stretch marks are caused by syndromes such as Cushing’s syndrome or Marfan syndrome, or from the overuse of powerful steroid creams or ointments on the skin.

Treating stretch marks

Most stretch marks aren’t particularly noticeable and will fade over time.

If you have unsightly stretch marks, or if they affect a large area of your body, you may want to try one of the treatment options available. 

Creams, gels, lotions, laser surgery and cosmetic surgery are all used to treat stretch marks. However, there’s little medical evidence to show that these treatments are particularly effective, so it’s important to be realistic about what they can achieve.

It should also be noted that laser treatment and cosmetic surgery for stretch marks aren’t available on the NHS, and private treatment can be expensive.

Read more about treating stretch marks.

Preventing stretch marks

In certain situations, such as during pregnancy, it isn’t possible to prevent stretch marks.

However, maintaining a healthy weight and looking after your skin can reduce your risk of getting them.

It’s so frustrating to look to the NHS and just be told that there is nothing you can do. There are private treatments such as DermaEraze offered privately that have proven results that have helped thousands of women, including me, at an affordable price. No one expects the NHS to pay for these treatments, but we do expect to be pointed in the direction of a solution. Most women in my situation are happy to save in order to have a treatment that works.

I am 29, haven’t had children, nor gained/lost weight. I have rather bad stretch marks on my breasts, hips and thighs…and started to get them on the back of my knees (sounds strange I know). I have never been larger than a size 8. I have been using Bio Oil for about 2 years now on and off and I haven’t really seen any improvement to my stretch marks. I visited a Doctor who said there isn’t really anything you can do about them and keep trying creams and oils, which really wasn’t helpful. I heard about derma rollers and thought I would give it a try. I have used the roller 4 times now and can’t see any improvement yet but I guess time will tell. I am really self conscious about my stretch marks and am petrified about having children because I can’t imagine what my body will look like after if I have them in abundance now! If anyone had stretch marks before pregnancy, I would be interested to know what happened to your body during and after the birth. Did they get worse? Did the amount of stretch marks double?

The Danaefabienne cream might help you to prevent stretch marks; just like it helped me and still does. I was even able to almost completely erase one very red streak on my tummy and two purple ones on my breasts.

Please help. Im 26, a size 10 and have had 2 kids. I have no desire for anymore and would like to gain back some body. My youngest is nearly 2 and I have what I would consider to be quite bad stretch marks on my stomach (mainly on the sides) which have now turned silvery white with a reddish tone in some lights. Some are quite wide and relatively long. Is there anything anyone could recommend for me to use?? It really needs to be no more than £20 ish – especially if its something that only last 3 months or so. Thanks!

I found bio oil helped a smidgen so did coco butter. Creams don’t help me at all. Only thing that has visibily reduced my stretch marks is mummies with tummies oil. You can only notis the marks now if you go up close. I have only been using this for just over a month and i am lovin my bump.

Honestly, for me it was Lamaze Belly Rub it s absolutely the best body butter for pregnant bellies. Its got lots of oils in the butter which slowly absorb into the skin making the skin softer/more elastic longer. Has great smell and isn’t overly watery/oily when its applied. You can feel the difference from using this butter as compared to Palmers coco butter. I love this butter with a passion, and i’m pregnant with twins so that’s gotta speak for something!

I have found Bio Oil to be very helpful on acne scars, and I have heard excellent things on what it can do for stretch marks. Worth a go! It is mid-price but lasts a long time. Use morning and evening for best results.

Hello, I’m 16 and I’ve had stretch marks since I was 13, they’ve never really bothered me but they are still appearing even though my weight and size is stable. They are appearing in place that will be noticeable like above hips and back of my legs. I moisturise with cocoa butter, e45 and body oils. But they still appear :(please some advice would be helpful. I’ve heard there are vitamin e injections that could help (heard from embarrassing body’s channel 4) could I get some more information on this topic please.

Diet has helped improve my stretch marks more than anything else. I’ve cut out all processed foods, coffee, alcohol etc and have progressed to a 100% raw vegan diet. I’m not saying you have to go that extreme but definitely substituting "bad" foods for more fruit and veg helps.

Hi, sorry to hear about your stretch marks. It sounds as if you have a healthy diet and that your stretch marks are not a result of being overweight. However, they are clearly causing you some distress, affecting your self esteem and making you self conscious.

You should go to visit your GP who will be able to examine your stretch marks and recommend suitable treatment options. Also, just to let you know that this topic is currently being reviewed and the updated version will be available within the next couple of weeks – good luck!

hello. I’m 14, nearly 15 and i have bad stretch marks on my inner thighs. I dont think its due to being overweight as i am a size 10 and have never been over just into a size 12. I also didn’t have much of a growth spurt as i have always been tall and have only developed the scars in the last few years. i have a healthy diet, i dont eat fast food, anything processed or sweets, and i only have the right amount of carbs and dairy each day and i eat a lot of fruit and vegetables. i’ve tried a number of creams and oils, etc. and it has only made them more purple/silver rather than red. my aunt is due to be treated by the nhs for acne and she said she was told that a similar thing could be provided for me, and i’ve heard some things are free for under 16’s. Also, in the "useful links" there is a link to the plastic surgery section, is that appropriate? i dont know what else i’m going to do, i dont show my legs and have refused to go swimming for the last 3 years, i think my mum is concerned with me being so self concious but i can’t show my legs how they are now. please reply and tell me if any of the information i’ve heard is correct. thankyou

Stretch marks

Preventing stretch marks

Stretch marks are very common and can’t always be prevented.

However, the following advice may help reduce your risk of developing stretch marks.

Healthy weight

Gaining weight rapidly over a short period of time is one of the most common causes of stretch marks.

Dieting that results in your weight quickly going up and down  so-called “yo-yo dieting”  can cause stretch marks. Therefore, avoiding rapid weight gain and weight loss can help prevent stretch marks occurring.

If you need to lose weight, you should do it slowly by eating a healthy, balanced diet and exercising regularly. You shouldn’t lose more than 0.5kg (1lb) a week.

Read more about how to lose weight safely.

Diet

It’s important to eat a healthy, balanced diet that’s rich in vitamins and minerals, particularly vitamin E, vitamin C, and the minerals zinc and silicon. These vitamins and minerals will help keep your skin healthy.

A balanced diet will provide all the vitamins and minerals that the body needs. Dietary supplements aren’t needed to prevent stretch marks developing.

During pregnancy

Stretch marks that occur during pregnancy (striae gravidarum) are usually due to hormonal changes that affect your skin. Gaining pregnancy weight steadily may help minimise the effect of stretch marks.

During pregnancy it’s normal for a woman to put on weight over a relatively short period of time. However, it’s a myth that you need to “eat for two”, even if you’re expecting twins or triplets.

You don’t need to go on a special diet if you’re pregnant, but you should eat a variety of foods every day to get the right balance of nutrients for you and your baby. Your diet should be rich in wholewheat carbohydrates, such as bread and pasta, as well as fruit and vegetables.

Read more about diet during pregnancy

During pregnancy, your weight gain should be slow and gradual. The amount of weight you put on will depend on the weight you were before you became pregnant. It’s normal to gain 1-2kg (2.2-4.4lb) over the first 12 weeks of your pregnancy.

As a rough guide, during pregnancy, women who are:

  • underweight (have a BMI of less than 18.5) should gain 12.7-18.1kg (28-40lb)
  • a normal weight (have a BMI of 18.5-24.9) should gain 11.3-15.9kg (25-35lb)
  • overweight (have a BMI of more than 25) should gain 6.8-11.3kg (15-25lb)
  • obese (have a BMI of more than 30) should gain 5-9.1kg (11-20lb).

Speak to your GP, midwife or health visitor if you’re worried about not gaining weight at a healthy rate, or if you’re concerned about your stretch marks.

Stretch marks

Symptoms of stretch marks

Not everyone gets stretch marks  it depends on your skin type.

Collagen is a protein in your skin, which keeps it elastic and stretchy. Having a lot of collagen in your skin makes it less likely that you’ll get stretch marks.

How stretch marks develop

Before the stretch marks appear, the affected skin will become thin, flattened and pink, and may feel itchy.

The stretch marks themselves then appear as red or purple streaks or lines, but can be pink, reddish-brown or dark brown, depending on your skin colour.

They can occur in patches of parallel lines on your body and often appear “scar-like”.

To start with, the lines will be slightly raised and may feel wrinkly, before eventually flattening out.

As the lines become flatter, they will begin to fade and change to a white or silvery colour.

Stretch marks usually fade and become less noticeable over time, but this can sometimes take years.

Where stretch marks occur

Stretch marks can occur anywhere where the skin has been stretched.

They usually  but not always  develop on areas where fat is stored, and can occur on your:

  • tummy (abdomen)
  • buttocks
  • thighs
  • upper arms
  • breasts
  • shoulders (in bodybuilders)

Stretch marks can also sometimes occur on the back, where they overlie the spine horizontally (rather like the rungs on a ladder), particularly teenage boys.

Stretch marks that are caused by Cushing’s syndrome (where a person has high levels of a hormone called cortisol in their blood) tend to be wider and larger, and can also appear on the face.

Stretch marks

Treating stretch marks

Stretch marks often aren’t noticeable and usually fade over time.

If you have stretch marks that affect a large area of your body, or if you’re worried they look unsightly, there are a few treatment options available.

However, there isn’t much medical evidence to show that these treatments work.

Camouflage

Cosmetic camouflage (make-up) is available over-the-counter at pharmacies and can be used for small areas of skin affected by stretch marks. Some types are waterproof and can stay in place for two to three days.

Creams, gels and lotions

The manufacturers of creams, gels and lotions often claim that they can remove stretch marks.

These products are essentially skin moisturisers and are available from pharmacies, supermarkets, and health and beauty shops.

It’s recommended that you apply these products when your stretch marks are still red or purple. However, it’s unlikely that these treatments can prevent stretch marks occurring, or make them fade any more significantly than they will with time alone.

Read more about preventing stretch marks.

Laser therapy

Laser therapy can’t completely remove stretch marks, but it may help fade them and make them less noticeable.

Several different types of laser therapy are used to treat stretch marks.

Pulsed dye laser treatment is one type of laser treatment available. It’s painless and can be used at an early stage, while your stretch marks are still red or purple.

The energy from the laser is absorbed by the blood vessels underneath your stretch marks. The blood vessels collapse and the red or purple colour either disappears completely or turns white. 

Laser therapy for stretch marks isn’t available on the NHS and is usually expensive. You will probably need a few treatments to obtain visible results. The exact number will depend on your skin colour and type.

Cosmetic surgery

Cosmetic surgery for stretch marks is expensive and rarely recommended.

If you have stretch marks on your tummy (abdomen) and a large amount of loose skin, it may be possible to have an operation known as an abdominoplasty or tummy tuck.

The procedure removes excess fat and skin from your abdomen, and also gets rid of stretch marks below your belly button.

As this type of surgery is carried out for cosmetic reasons (to improve appearance), it isn’t available on the NHS. It also carries a number of associated risks and can cause considerable scarring.
