Have you noticed fine scars on your skin and wonder what they are? Where do they come from? Maybe you even feel self-conscious or worried that these marks might be permanent. 😣
Rest assured, you are not the only one. The stretch marks are extremely common in women.
But understand their origin and how they work, It's a big step to prevent and accept them!
What is a stretch mark?
What are these small scars on your belly, hips, or thighs? These marks can be worrying or give the impression that your skin is deteriorating for no reason.🤔
Les stretch marks are superficial skin lesions who appear when the skin is subjected to rapid stretching . This can occur during puberty, pregnancy, rapid weight gain, or muscle mass increase.
When your skin stretches too quickly , she "cracks": the collagen and elastin fibers break, leading to the formation of streaks, some small scars.
They can appear on several areas: the belly, the hips, the thighs, the breasts, the arms, or even the buttocks.
First red, purplish, or dark (\"immature\" stretch marks), they then evolve into lighter shades, until they become pearly white (stretch marks "mature").
Good news: even if the stretch marks are permanent , there are ways to prevent their appearance and for reduce their appearance over time thanks to appropriate care!
Now that you have a better understanding of what stretch marks are, you are probably wondering: why do some women have them and others don't? 🤗
Why do we have stretch marks?
You take care of your skin, yet stretch marks appear without warning! It's frustrating, isn't it? 😩
What you need to know is that The appearance of stretch marks is often linked to sudden changes in the body, that you do not always control.
This phenomenon can occur at different times in life, such as:
- puberty
- pregnancy
- with weight variations
- with a muscle grip
- based on genetic predispositions

Hormonal changes during puberty
To adolescence, the body changes quickly : growth spurt, hormonal transformation, development of shapes… And, the skin does not always have time to adapt !
Result, the Stretch marks affect more than 40 to 50% of the young population , which is why teenage girls appear from the stretch marks , often on the thighs, breasts, buttocks, or hips.
Pregnancy
During pregnancy, the belly rounds quickly. Skin stretching, associated with an increase in hormones, weakens the skin. The stretch marks usually appear between the 6th and 9th month , mainly on the stomach, but also the breasts, hips, and buttocks.
Rest assured: these marks can fade after childbirth. 😊
Rapid weight fluctuations
You have gained weight quickly ? The skin can suffer from it.
The sudden weight fluctuations put under tension the supporting fibers of the dermis , which can tear. This explains why stretch marks are common during yo-yo weight gain (repeated weight gain and loss) which gradually damages the skin tissues. 🫤
Rapid muscle gain
You are given a discount of intense sport ? Or do you have mass gain to the gym? Well done! 🎯
But if the muscle growth is too fast , the skin may not keep up, and the stretch marks appear on the arms, shoulders, or thighs.
Genetic predispositions
Some of us are more prone than others to developing stretch marks. Why? Because it all depends on natural elasticity of the skin , often determined by your genes.
If your mother or sister are prone to stretch marks, you are more likely to develop them as well. 💡
The lack of collagen or less elastic skin
The collagen and elastin are the pillars of your skin. They ensure its flexibility and its ability to return to its original shape. But with age, or in case of deficiency, their production decreases.
Result: more fragile skin, more prone to "breaks." 😓
You got it: the stretch marks can appear at different stages of life and for multiple reasons, often beyond your control. But then, where do they most often settle on your body? Let's take a look at the most affected areas. 👀
Where do stretch marks appear?
You have noticed the presence of stretch marks on your body, but you don't know if it's normal in that area? Rest assured, no matter their location, they do not pose a danger to your health.
However, knowing the body areas most prone to the development of stretch marks, allows to be able to anticipate their appearances.
Hips, thighs, and buttocks: areas with high hormonal impact
These parts of the body are directly influenced by hormones, especially during adolescence. That is why 90 to 95% of young girls develop stretch marks during puberty , mainly on :
- The hips (effect of lateral "growth spurt"),
- The thighs (often on the outside),
- The buttocks (area with high skin tension in case of weight gain or sports activity).
These areas are also affected when engaging in intensive sports or a rapid muscle strengthening program. 💪
Breasts and décolleté: often forgotten, but very exposed
Whether it is during the puberty , the pregnancy or following a weight gain , breasts can gain volume very quickly.
The skin, thin and delicate in this area, is particularly prone to internal cracking.
Result: from the stretch marks appearing on the sides of the breasts or between the chest, sometimes even on the upper part of the neckline.
The wearing of a adapted bra and one regular hydration limits the risk of stretch marks. 🤗
The belly during pregnancy: the most prominent area
This is the most well-known area when it comes to stretch marks, especially during pregnancy. As your belly rounds, the skin stretches intensely and rapidly , especially from the 6th month of pregnancy.
Result: the deep fibers crack and reveal red or purplish stretch marks.
🔍 Stretch marks usually appear during the 2nd and 3rd trimesters of pregnancy, affecting approximately 80 to 90% of pregnant women , mainly on the belly, breasts, hips, thighs, and buttocks.
Even after childbirth, they may persist but gradually diminish!
Bras (inner): rarer but possible
The stretch marks who appear at the inside of bras are due to: rapid muscle growth, or in some teenage girls during periods of body transformation or weight gain.
People with thin skin or low natural elasticity are more prone to it. 🧬
Calves, back, behind the knees: secondary areas
Less common but entirely possible, stretch marks can also affect:
- The lower back and the love handles (in case of rapid weight gain or mass increase),
- The calves (especially among athletes),
-
The back of the knees (during growth spurts in adolescence).
These less visible locations are no less a source of discomfort or insecurity for some of you, but remember that these marks are natural and common 💗
You now know that the stretch marks can appear just about anywhere on your body, except under the soles of your feet.
According to your history, your hormones, and your skin, they are all different. Their color, shape, or age influence how to take care of them. 🤗
The types of stretch marks: how to recognize them?
From stretch marks have appeared on your skin … but you don't know if it will be permanent or not? 🤔
Depending on their appearance, you may or may not be able to make disappear , adapting the care provided.
You will see that some are easier to mitigate than others, at the right time! ⏳
1. Immature stretch marks: the most recent ones
This is the first stage in the formation of stretch marks. They are also called « striae rubrae » (on fair skin) or "striae nigra" (on dark skin). Their color varies depending on the skin type.
- Pink, red, or purplish in light carnations
- Dark brown, violet or almost black on more pigmented skin
These colors are due to a inflammation of the skin fibers , in response to the sudden stretching of the skin. 🧬
They indicate a active healing phase, which makes it the ideal time to intervene with targeted treatments.
The earlier you act, the better your chances of mitigating them are great. It's a valuable opportunity that should not be missed! 😊
2. Stretch marks mature: the oldest ones
Over time, the stretch marks lose their bright color and become white , pearly or sometimes slightly shiny, even hollowed out.
On the calls "striae albae" . They mark the end of the inflammatory process : the skin has healed , but the lesion remains visible as a fine scar. 👩⚕️
At this stage, they are more difficult to process : treatments can no longer act on the initial regeneration phase. However, it is still possible to improve the texture and appearance thanks to nourishing, firming treatments or certain dermatological techniques.
It is better to act quickly at the first appearance of stretch marks to optimize your results. The younger a stretch mark is, the more receptive it is to treatment!

Better to anticipate rather than repair: prevent stretch marks, It's already a big step towards smooth skin. Don't move, we're sharing our best tips to prevent their appearance right now.👇
How to prevent stretch marks?
As we have seen, certain periods of your life such as adolescence, pregnancy, or a change in lifestyle, increase the risk of stretch marks appearing. The good news: simple actions make it possible to effectively prevent . 🤗
1. Stay hydrated 💧
It cannot be repeated enough: a well-hydrated skin is more supple skin and more durable!
Drink at least 1.5 to 2 liters of water per day , especially if you are pregnant, if you sweat a lot, or if you have naturally dry skin.
Internal hydration promotes your skin's elasticity and supports collagen production. 💡
2. Nourish your skin 🧴
Apply morning and evening a moisturizing or nourishing treatment on sensitive areas : belly, hips, thighs, buttocks, and breasts. And gently massage in circular motions to stimulate blood circulation, promote the absorption of the treatment, and strengthen the skin fibers. ✅
Favor rich textures like body butters, vegetable oils (sweet almond, coconut…) or the specific anti-stretch mark creams (even if they are not here yet) !
💡Choose treatments rich in nourishing active ingredients like shea, oats or marine extracts : they strengthen the skin barrier, improve skin elasticity, and limit the appearance of stretch marks.
3. Adopt a balanced diet 🥗
One diet rich in antioxidants, vitamins (A, C, E), essential fatty acids, and proteins promotes healthy skin.
Avoid snacking, "yo-yo" diets, or rapid weight gain: sudden fluctuations are a major factor in stretch marks.
Prefer:
- fresh fruits (orange, kiwi, red fruits),
- green vegetables (broccoli, spinach),
- vegetable oils (rapeseed, flax, walnut),
- eggs, fish, legumes.
4. Be consistent
A treatment applied once a week will have little impact! However, consistency makes all the difference.
Take this time for yourself every day: hydrate, massage, pamper your skin. 💆♀️
It is also a moment of relaxation, of reconnecting with your body. And your skin will thank you! 🙏
Adopting a healthy lifestyle, moisturizing your skin daily, and nourishing it deeply are simple yet powerful habits to help prevent the appearance of stretch marks.
And if you are pregnant or planning to be, these actions become even more important: from the first trimester, gently massage the sensitive areas (belly, breasts, hips) for improve skin elasticity. Also remember to stay well hydrated from the inside (1.5 to 2 liters of water per day) and to favor a balanced diet to limit rapid weight gain.
What if the stretch marks are already there?
These so-called "recent" stretch marks are in the inflammatory phase: the skin is reacting to tension, and it is precisely at this moment that it is most receptive to treatment.
Continue to apply the care listed above and you will limit their size.
Each treatment, each daily gesture can help your skin better cope with these major changes and reduce the risk of stretch marks. 💕
How to reduce the appearance of healed stretch marks?
Are your stretch marks making you self-conscious, but no cream seems to work on them anymore? Have you already tried natural treatments, but without any results? There are more advanced options to make them disappear or reduce their appearance, but beware: they come with some constraints! 😓
Vitamin A acid (tretinoin) creams 🧴
This is a cream that contains a derivative of the vitamin A (called tretinoin). This substance promotes the cell renewal and stimulates collagen production.
In other words, it helps your skin heal faster.
She is mainly prescribed to young girls between 12 and 14 years old (puberty) and only with a medical prescription!
⚠️ Important: these creams are strictly prohibited for pregnant or breastfeeding women, as they can be toxic to the fetus.
Fractional CO2 or Erbium laser
The abrasive laser acts by creating micro-needles in the skin to stimulate the production of new collagen fibers. It "smooths" the area and reduces the appearance of stretch marks. The results are often spectacular after a few sessions: the texture improves, the color whitens, and scars become less noticeable.
The drawbacks? Because yes, there are some!
The aftereffects are sometimes severe: intense redness, peeling skin, oozing, burning sensation, and require dressings and post-laser care for several days.
Note: recovery takes longer than with other treatments. 💡
To give you an idea of the treatment, it lasts 4 sessions spaced 1 month apart and costs on average €120 to €240 per session depending on the area.
Microdermabrasion
It is a mechanical exfoliation technique: a machine projects microcrystals onto the skin and “sands” the surface to stimulate cell renewal. It is gentler than the laser, better tolerated, and can improve the texture of stretch marks over the course of sessions.
It's less effective on very old or deep stretch marks! You need to plan ahead several spaced sessions to see a difference. ✅
Strong chemical peels
The dermatologist applies a chemical acid product on the area. This causes a controlled destruction of the superficial layers of the skin, which will then be regenerate. Peeling can reduce the depth and color of stretch marks.
However, this treatment is reserved for strictly medical use and the aftermath is quite painful: the skin burns, scabs form and take about 7 to 10 days to fall off!
Results vary greatly from one patient to another. 🌸
⚠️ These treatments can be expensive and require medical supervision.
What if we learned to accept them?
The stretch marks tell a story: that one of a body that changes, that grows, that lives. They are natural, common, and do not diminish your beauty in any way. You can take care of them, reduce them, or simply accept them, without pressure. 💕
