Stretch marks are one of the most common skin changes after pregnancy - according to studies, they affect between 55% and as many as 90% of women [1]. They are completely natural and harmless, but they can be a source of discomfort. Below I explain where they come from, what genuinely helps with prevention during pregnancy and what is better avoided, and when after giving birth effective treatment can begin, including laser stretch mark treatment in Wrocław.

Where stretch marks in pregnancy come from
Pregnancy stretch marks (striae gravidarum) are linear scars that form when rapidly stretched skin is damaged in the connective tissue layer; hormonal changes also contribute to this [2]. They most often appear on the abdomen, breasts and thighs, usually in the second half of pregnancy.
Several factors influence their development - the ones most often identified in studies are [1]:
- younger maternal age,
- a family history of stretch marks (predisposition),
- higher body weight before pregnancy and before delivery,
- higher birth weight of the baby.
In other words: genetics and the rate of weight gain play a large part, and we do not always have full control over them.
Prevention in pregnancy - what makes sense and what does not
To be honest: no method prevents stretch marks 100%, and the evidence for most products is limited or inconclusive [1][3]. According to research reviews, some moderate signals of effectiveness have been found for [1]:
- products containing Centella asiatica extract,
- hyaluronic acid,
- daily massage of the areas prone to stretch marks (the massage itself may make a difference).
On the other hand, popular oils (e.g. olive oil) did not produce a statistically significant difference in controlled studies [1]. General, sensible rules - gradual weight gain, hydration and regular skin moisturising - will do no harm and support the condition of the skin [2].
When to start treatment after giving birth
Fresh stretch marks (pink, red) respond to treatment better than old, white ones - so from the point of view of effectiveness, it is not worth waiting for years [1]. However, contraindications must be kept in mind: laser treatments are performed only after breastfeeding has ended. The best time and method are determined individually during a consultation.
How stretch marks after pregnancy are treated
Today the most effective options are procedures that stimulate the skin to remodel. In studies, fractional lasers usually achieve a 50–75% improvement in the treated stretch marks [1], and the treatment works by stimulating collagen and elastin production in a controlled way. At MM Clinic we use a fractional CO2 laser - usually as a course of 3–6 treatments every 4–6 weeks; the effects continue to build for 3–6 months after the course. Details, prices and contraindications are described on the laser stretch mark treatment page. I explain why the stage of stretch marks matters in the post red and white stretch marks.
Stretch marks cannot be removed completely - they are scars [2]. A realistic and honest goal is to clearly reduce their visibility and improve the texture of the skin.

Does every woman get stretch marks in pregnancy?
Not every woman, but they are very common - according to studies, they affect 55–90% of women. Genetics and family history play a major role.
Can stretch marks in pregnancy be prevented?
Not 100%. The evidence for most products is limited; some moderate signals have been found for Centella asiatica, hyaluronic acid and daily massage. Gradual weight gain and moisturising the skin also help.
Can retinol creams or laser treatments be used during pregnancy?
No. Retinoids (e.g. tretinoin) are contraindicated in pregnancy, and laser treatments are performed only after breastfeeding has ended.
When after giving birth can stretch mark treatment begin?
Laser treatments are performed after breastfeeding has ended. Fresh, pink stretch marks respond better than white ones, so it is not worth waiting for years - the timing is determined during a consultation.
Will stretch marks after pregnancy disappear completely?
No. They are scars and rarely disappear completely. Treatment clearly reduces their visibility and improves the texture of the skin, but the result varies from person to person.
