Stretch marks are purple grey or red streaks that appear on the skin due to skin elasticity.  Stretch marks can appear on any body part, but the most common places include the thighs, stomach and bum. In most cases, both men and women are reluctant to show off the affected body part in public.  

Thankfully, there are several medical treatments and home remedies that can help drastically reduce the appearance of these skin denting lines. 

This article shall explain the causes of stretch marks on thighs, stomach and bum, how to prevent these causes, and how to get rid of the market and have blemish-free skin. 

Stretch marks on thighs, stomach and butt

Stretch marks are reddish, purple, or pinkish indented streaks on any body part, but often around the thigh, stomach and butt. Tiny tears in the dermis layer cause these streaks or lines, and they tend to fade into greyish colour over time. Stretch marks are common in people due to the expansion of the skin’s collagen and elastin fibres. 

Types of stretch marks

Type of stretch marks explained

Yes, there are different types of stretch marks, 

depending on the appearance and formation.

Striae rubrae

This is known to be the onset of stretch marks on the skin as it indicates the flattening of the epidermis and loss of rete ridges. This makes the collagen fibres thicken more and appear in parallel patterns. It also causes the elastic fibres to decrease. 

Stretch marks at this stage are usually flat or slightly raised in pink or red. They also tend to be itchy.

Striae alba

Striae alba is a more mature stage of stretch mark formation. As the striae rubrae progresses within months, the stretch marks become more hypopigmented, irregularly shaped, in a scar-like wrinkled texture. 

Striae alba is usually white and becomes more prominent due to the loss of skin elasticity as you age. 

Striae gravidarum

These types of stretch marks are also known as pregnancy stretch marks. They appear in parallel lines on the abdomen, thigh and breast, usually in the second trimester. 

These stretch marks do not cause problems for the baby or the mother, and they tend to fade and become less noticeable after childbirth.

Striae caerulea

These types of stretch marks affect those with darker complexions because of the amount of melanin present in their skin. They usually appear in purplish or dark blue colours.

Striae nigrae

These are also types of stretch marks that are common with people who have darker complexions. They are usually linear stretches in black or dark grey colours, which later fade into whitish lines. 

Striae Atrophicans

Those with Cushing’s syndrome and those who have used corticosteroids for a long time after their surgery often develop a cutaneous condition that causes the appearance of stretch marks. These stretch marks with purple or pink symmetric lines are called striae atrophicans. 

Causes of stretch marks

Causes of stretch marks explained

The primary and only cause of stretch marks on the body is the stretching of the skin, which can affect anybody. How severe the stretch mark will be, depends on many factors. These factors are;


One of the characteristics of puberty is weight gain, which gives room for the skin to overstretch in areas like hips, thighs, and breasts. These stretches cause stretch marks on the body. Stretch marks are standard parts of puberty for most people, especially women and those who gain a lot of weight during that period. 


Rapid weight gain over a short period also stretches the skin, and excessive skin stretching damages collagen, thereby leading to stretch marks. 


The tummy needs to expand to accommodate the baby, and this often leads to somewhat brown, purple, pink or red stretch marks on the stomach. Apart from the tummy, the skin on other parts of the body, such as breasts, thighs and hips, also gets stretched and then causes stretch marks on these areas. However, there can still be stretch marks on the tummy without pregnancy, as long as the skin around that area is stretched. 

Family history

Genetics also play a vital role in whether you have stretch marks. In a study conducted to assess stretch marks risk factors among adults in Riyadh city, KSA, about 70% of the participants had a family history of stretch marks. 

Muscle gain

Muscle growth, either through routine exercise or repeated use of steroids, can cause stretch marks. Once the muscles start bulging, the skin stretches and stretch mark streaks appear. 

Breast implant surgery

According to a plastic surgeon, one of the factors to be considered before embarking on breast surgery is skin type. Soft, thin skin cannot accommodate large implants, as they are at risk of skin stretching and drooping. 


Some drugs can cause the skin to stretch and develop streaks. These drugs can cause weight gain, bloating, and swelling, thereby leading to stretch marks on thighs, stomach and bums. These medications include; birth control pills and corticosteroids.

Health conditions

Some health conditions can cause sudden growth, weight gain, or other skin issues that make the skin develop stretch marks. Examples of these conditions are; Marfan syndrome, Cushing’s syndrome, and  Ehlers-Danfoss syndrome. People with these health conditions are even more at risk of having stretch marks on their bodies.

These treatments are usually carried out by a certified health professional like Nina Bal who, after you make an appointment, will discuss the cost implication, risks and expectations of any treatment method chosen. 

Parts of these treatments are;

Microneedling with derma roller, derma stamp or derma pen 

The process of micro-needling, also known as collagen induction therapy, helps the skin produce elastin and collagen that enables the skin to regain its elasticity. This method uses microneedles to make tiny punctures in the skin to boost collagen and elastic development. Microneedling can improve stretch mark scars by about 75% after 1-3 treatments. You can expect visible results within six weeks after the procedure. For ultimate results, it is advisable to have three treatment sessions every four weeks. This will lead to complete skin rejuvenation and less visible stretch marks.

Chemical peel

A chemical peel is another way to fade off the appearance of stretch marks on the body. This process makes use of acids such as glycolic acid. A review affirms that chemical peels profoundly exfoliate the skin and foster collagen production.

Laser therapy

The process involves directing concentrated light rays on the areas with stretch marks to smoothen the scars and stimulate new skin growth. 

Other medical treatments include; 

  • Microdermabrasion
  • Radiofrequency therapy
