Before going over each type of stretch marks, let's refresh our memory briefly with some facts about stretch marks.

Stretch Marks, what are they?

The skin is the most stretchy organ of the human body, it can extend or retract to a certain limit. The layer of skin responsible for its elasticity is called "the Dermis". 

The skin stretches when the body changes its shape because of weight gain, puberty, growth of the muscle mass, or any other factors that might affect your weight or shape.

If those body changes happen fast. The elasticity of the skin reaches its maximum mechanical limit. 

Once it happens, it will cause a collagen breakdown in the Dermis.

Once the dermis is damaged, our organism will start a healing process leading to the appearance of stretch marks

Stretch marks or striae are technically scars. They will fade out with time (serval years) but they will never disappear completely.

So, after this brief reminder, let's dive in and start with the first and most widespread type of stretch marks.

Stretch Marks type: Striae Distensae

Striae Distensea are the most prevalent type of stretch marks. They are associated with the following causes:

  1. Quick weight/shape changes
  2. puberty. 
  3. Steroid use
  4. Pregnancy
  5. Obesity
  6. Cushing syndrome
 The picture below shows Striae Distensae.

Striae Distensae

Striae Distensae appear like lines pointing to the perpendicular direction of the skin. There are 2 main forms of striae Distensae: Stria Rubra and Striae Alba. 

Less frequent forms of Stria Distensae are called Striae Nigra and Striae Caerulea.

In the following section, we're going to discuss each one of these forms.

Stretch Marks type: Striae Rubra

Rubra in Latin means Red, Striae Rubra is the early stage of striae Distensae. Usually, they can be red, pink, or purple. After 7 to 12 months, they start losing their color and may turn either white or black, depending on the individual skin pigmentation. 

Striae Rubra

What characterizes this type of stretch marks is that they have the best response to stretch marks treatments.

Why you should treat Striae Rubra in priority

Striae Rubra is a type of stretch mark that can be treated relatively easily comparing to the other types of stretch marks. The cutaneous lesions are still fresh. Unlike the striae, Striae Rubra has a great response to the majority of stretch marks treatments available.

Stimulating collagen production in the concerned areas may reduce drastically the future aspect of stretch marks.

Topical creams treatments can be a very effective way of getting rid of this type of stretch marks.

Topical Creams to treat stretch marks: our recommendation XYZCollagen

XYZ collagen is a topical cream that boosts the collagen production of the skin. The natural active ingredients of this cream have been clinically proven to treat and prevent stretch marks. For more info check out XYZ collagen official website.

To boost the XYZcollagen result, you can start exfoliating dead skin around the area of stretch marks. 

Stretch Marks type: Striae Albae

Striae alba is the mature stage of Striae Distensiae. After a few months, striae Rubra transforms into Striae Alba. Striae alba are white stretch marks and are the hardest stretch mark to treat. Over the years, they will eventually start to diminish and fadeout to a certain degree.

Striae Albae

Striae alba Treatments

Unlike Striae Rubra, Topical creams and even laser therapy may not be very efficient in treating striae alba. The reason is that stretch marks tissues forming this type of striae are already atrophied. However, some recent clinical trials showed promising results in the treatment of striae albae. 

The treatment consists of a combination of 2 existing treatments: Fractionated Microneedle Radiofrequency and Fractional CO2 laser. As you can see in the picture below, this treatment shows promising results.

Stretch Marks type: Striae nigra

Striae Nigra

Striae Negra are black stretch marks. They are a rare form of striae Distensiae. They develop only within people that have dark skin. The reasons are not clear, but recent studies suggest that this type of stretch marks are caused by Hypermelanosis around the areas of the skin affected by stretch marks.

Stretch Marks type: Striae Caerulea

Striae Caerulea are dark blue Stretch marks. Like Striae Nigrae, they are not a very prevalent form of striae Distensiae and only applicable to persons with darker skin.

Striae Distensae and Ethnicity

The result of the studies published in The American journal of dermatology show that black women have higher chances than caucasian women of developing striae Distensae. Darker skin increases the chances of striae distensae to occur. 

However, if you have dark skin, you still can reduce this risk by by applying some measures which aim to prevent stretch marks. Such as having a balanced diet, Working out, moisturize the skin, and control your weight.

Striae Distensae (Stretch marks) and Gender prevalence

A study conducted on a group of 131 adolescents showed that males have almost the same chances of getting affected by striae distensae as females when exposed to a stretch marks cause.

Summary: Striae Distensae

Striae Distensae are the most prevalent type of stretch mark among men and women. They may occur when a person experiences a significant weight loss or gain, puberty, pregnancy, Obesity, and Cushing syndrome.
There are 4 different forms of Striae distensae.
  1. Striae Rubra early stage of Striae Distensae (red or purple stretch marks) and the easiest to heal.
  2. Striae Alba which is a mature Striae Distensae (white stretch marks)
  3. Striae nigra and Caerulea mature Striae Distensae ( black or dark blue stretch marks), which develop among persons with darker skin.

In the next section, we're going over the most widespread type of stretch marks among women, which is Striae Gravidarum.

Stretch Marks type: Striae Gravidarum

Striae Gravidarum

Striae Gravidarum refers to stretch marks caused by pregnancy. Most pregnant women will get this type of stretch marks (the incidence rate is between 50% to 90%). Their thickness is larger than that of regular Striae Distensiae. 

Striae Gravidarum are formed usually after the 24th week. However, they can show up sooner in 43% of cases. Research indicates that these types of stretch marks are caused by a change in the skin collagen structure due to hormonal changes during pregnancy and the uterus growth.

However, you can prevent stretch marks during pregnancy by following these steps:

  1. Exercise
  2. Avoid stress
  3. Have a vitamins-rich and balanced diet
  4. Moisturize your skin

As months pass by, they will start fading out and become white. Striae Gravidarums are typically located on the belly, hips, and breasts.

Risk factors of Striae Gravidrum

Some behaviors and Factors raise the risks related to the Striae Gravidarum. Recent research showed that a high BMI ( basal mass index) before pregnancy, which is associated with overweight, raises the chances of developing Striae Gravidrum and striae Distensiae.
