What Are Stretch Marks?

Stretch marks, also known as striae, are lines or streaks that develop when the skin stretches or changes faster than it can naturally adapt.


They often appear after pregnancy, puberty, rapid weight gain, weight loss, muscle growth or hormonal changes. Stretch marks commonly affect areas such as the stomach, breasts, thighs, hips, arms, bottom and back.


Stretch marks are very common and are not usually harmful. They may first appear red, purple, pink, brown or darker depending on skin tone, before gradually fading to a lighter or silvery colour over time.


Although stretch marks may become less visible naturally, they do not always disappear completely. Professional treatments may help improve their texture, colour and overall appearance by supporting collagen renewal and skin repair.

Types of Stretch Marks

Stretch marks can look different depending on their age, colour and depth.

 

Red or Purple Stretch Marks

Newer stretch marks often appear red, pink, purple, brown or darker depending on skin tone. These are sometimes called striae rubrae.

 

At this stage, the marks may look more noticeable and can sometimes feel slightly raised or itchy.

 

White or Silver Stretch Marks

Older stretch marks usually fade over time and may become white, silver, pale or slightly indented. These are sometimes called striae albae.

 

Older stretch marks can be more difficult to treat, but professional treatments may still help improve texture and visibility.

 

Pregnancy Stretch Marks

Pregnancy stretch marks commonly appear on the stomach, breasts, hips and thighs as the skin stretches to support body changes.

 

Weight Change Stretch Marks

Rapid weight gain or weight loss can cause stretch marks on areas where the skin has stretched or loosened quickly.

 

Muscle Growth Stretch Marks

Stretch marks may also appear after rapid muscle growth, especially around the shoulders, chest, arms or thighs.

What Causes Stretch Marks?

Stretch marks develop when the middle layer of the skin, known as the dermis, stretches too quickly. This can affect collagen and elastin fibres, which help keep the skin firm, flexible and supported.
 
When these fibres are stretched beyond their normal limit, small tear-like changes can form in the skin. As the skin heals, stretch marks may become visible as lines, streaks or indented marks.
 
Common causes and contributing factors include:
 
  • Pregnancy
  • Puberty and growth spurts
  • Rapid weight gain
  • Rapid weight loss
  • Muscle growth or bodybuilding
  • Hormonal changes
  • Genetics
  • Reduced collagen and elastin
  • Long-term steroid use
  • Certain medical conditions
Some people are more likely to develop stretch marks because of family history, skin type, hormones or how quickly their body shape changes.

Common Areas Affected by Stretch Marks

Stretch marks can appear anywhere the skin has stretched, but some areas are more commonly affected.
 
Common areas include:
 
  • Stomach
  • Breasts
  • Chest
  • Upper arms
  • Thighs
  • Hips
  • Bottom
  • Back
  • Shoulders
  • Flanks
The appearance may vary depending on skin tone, age of the stretch marks and how deeply the skin has been affected.

How to Help Prevent Stretch Marks

Stretch marks cannot always be prevented, especially during pregnancy, puberty or genetic body changes. However, supporting skin health may help reduce risk or severity.
 
Helpful steps include:
 
  • Keeping the skin moisturised
  • Maintaining steady weight changes where possible
  • Staying hydrated
  • Supporting skin with a balanced diet
  • Avoiding unnecessary steroid cream use unless prescribed
  • Wearing SPF on exposed areas
  • Treating new stretch marks early
  • Avoiding harsh scrubs on sensitive stretched skin
Prevention is not always possible, but early support may help improve the skin’s ability to recover.

Professional treatment may help if stretch marks are affecting confidence, texture or skin appearance.
 
You may wish to seek professional support if:
 
  • Stretch marks are new and very visible
  • Older stretch marks have become white or indented
  • Stretch marks developed after pregnancy
  • Stretch marks appeared after weight loss or muscle gain
  • Skin texture feels uneven

Stretch Mark Treatment Options in the UK

Stretch mark treatment focuses on stimulating collagen production, improving skin elasticity and reducing the visibility of marks. While stretch marks cannot usually be completely removed, their appearance can be significantly improved with professional treatment.
 
Treatment may help:
  • Improve skin texture
  • Increase collagen production
  • Reduce redness in new stretch marks
  • Improve the appearance of older white stretch marks
Microneedling creates controlled micro-injuries in the skin to stimulate natural collagen and elastin production. This helps strengthen the dermal layer and improve the appearance of stretch marks over time.
 
Microneedling may be suitable for:
  • Early red stretch marks
  • Mild to moderate white stretch marks
  • Areas such as the abdomen and thighs
Multiple sessions are typically recommended for optimal results.
Laser treatment uses focused energy to target damaged tissue and promote skin renewal. Certain lasers can help reduce redness in newer stretch marks and stimulate collagen production in older marks.
 
Laser therapy may be suitable for:
  • Persistent stretch marks
  • Textural irregularities
  • Combination treatment plans

Frequently Asked Questions About Stretch Marks

What are stretch marks?

Stretch marks are lines or streaks that develop when the skin stretches or changes faster than it can naturally adapt.

Stretch marks may be caused by pregnancy, puberty, rapid weight gain, weight loss, muscle growth, hormonal changes, genetics or reduced skin elasticity.

Stretch marks often fade over time, but they may not disappear completely because they are a form of dermal scarring.

Stretch marks usually cannot be removed completely, but professional treatments may help improve their texture, colour and overall appearance.

The best treatment depends on the age, colour and depth of the stretch marks. Options may include microneedling, laser treatment or RF microneedling.

Microneedling may help improve stretch mark texture by stimulating collagen and elastin production in the skin.

Laser treatment may help improve the colour, texture and visibility of selected stretch marks, depending on skin type and stretch mark age.

Newer red or purple stretch marks may respond more quickly than older white or silver stretch marks, although both may improve with the right treatment plan.

The number of sessions depends on the area treated, stretch mark depth, skin type and treatment method used.

Professional advice may help if stretch marks are affecting confidence, are very visible, feel textured or have not improved with time or skincare.
