You can’t see them — and that’s precisely the point. They streak across your back, out of sight, yet you know they’re there, and they make you self-conscious. Back stretch marks, particularly around the lower back, are something many people have in common. But why do they appear on this specific area of the body, and more importantly, what can you do about them?
Sommaire
Why do I have stretch marks on my back?
There are several reasons why stretch marks can appear on the back. Here are some of the most common.
1. Adolescence
This is the period most likely to trigger stretch marks on the back, especially in the lumbar area. They are caused by rapid, sudden growth spurts. The skin, which has a degree of elasticity thanks to its collagen and elastin fibres, is put under significant strain during puberty. Bone growth spurts, changes in body shape… all it takes is an overly intense stretch for the elastic fibres to break. Inflammatory stretch marks, red or purple, then appear. The back is particularly affected during adolescence, as the body “lengthens” dramatically in this area.
2. Significant weight fluctuations
Sudden weight loss or gain takes a toll on the skin which, despite its elasticity, can be weakened by abrupt stretching. For some people, weight fluctuations will have no visible effect on the skin. But for the majority, they will trigger stretch marks, which can appear on the back — particularly in the thoracic area (around the latissimus dorsi, teres major and teres minor muscles). Stretch marks linked to weight changes are generally finer than those caused by hormonal factors.
3. Elevated cortisol
Cortisol, often called the “stress hormone”, is naturally produced by the body. It helps regulate energy release when the body needs it: upon waking, during brief periods of stress, or in emergency situations. In certain circumstances (both external and internal), blood cortisol levels can spike and remain persistently high — a condition known as hypercortisolism. This can occur in the following situations:
- The development of chronic stress
- Long-term corticosteroid use — to manage the effects of rheumatism, allergies or certain conditions (such as inflammatory bowel disease)
- Cushing’s syndrome, which involves persistent hypercortisolism
Sustained high cortisol levels weaken the dermis’s elastic network. The skin becomes dry and rough, making it particularly prone to stretch marks. It is not uncommon to see striae appear across various parts of the body. In cases of Cushing’s syndrome, the back is especially affected. The stretch marks are often vertical, very wide and deeply coloured.
4. Pregnancy
It is relatively uncommon for pregnancy stretch marks to appear on the back. They typically develop on the stomach of the expectant mother, as well as on the bust, thighs and hips. That said, pregnancy brings such profound changes to the body that, under the combined effect of several factors (hormones, morphological transformation, changes in skin quality), stretch marks can sometimes form on the lower back of pregnant women.
5. Physical activity
Certain sports can cause stretch marks. This is particularly true of activities that involve rapid, significant muscle mass gain in the back: weight training, weightlifting, bodybuilding. That said, stretch marks more commonly appear on areas such as the arms, shoulders or chest (in the case of stretch marks in men). Muscle hypertrophy creates tension in the dermis. If this tension becomes too intense, the elastic fibres may give way under the strain and tear, leading to the appearance of stretch marks.
What are the solutions for back stretch marks?
1. Prevention
Preventing stretch marks is no easy task — you never quite know where, when or whether they will appear. That said, a few simple habits can help reduce the risk of developing stretch marks on your back.
- Stay well hydrated: the body is made up of around 70% water. Drinking enough is essential. Water, herbal teas, fresh juices and broths are all great options. Try to limit alcohol, as it contributes to dehydration.
- Eat well: certain minerals and vitamins are particularly beneficial for the skin. Vitamins A, B5, C and E, along with zinc, copper and silicon, help preserve the dermis’s resilience and elasticity. Don’t hesitate to include offal, nuts and seeds, seafood, dried fruits, fresh fruit and vegetables, and wholegrains in your diet. These will help nourish your skin and keep it in good condition.
- Practise gentle sports and stretching: high-intensity, high-impact sports can affect your skin and contribute to back stretch marks. However, physical activity is largely beneficial overall. Regular exercise not only helps keep the factors that encourage back stretch marks in check (weight gain, elevated cortisol), but also slows skin ageing and improves oxygenation. Opt for a variety of gentle activities and complement them with regular stretching.
- Care for your skin: build a moisturising routine, because your skin needs nourishment both from within and from the outside. Choose nourishing, protective products such as natural plant oils (olive, sweet almond, coconut), plant butters (shea), or Aloe Vera gel and suitable creams.
2. Technical solutions
Certain aesthetic techniques aim to reduce the visibility of back stretch marks. They focus on two main objectives:
- Smoothing the indented appearance of stretch marks: peeling, cosmetic surgery, dermabrasion.
- Stimulating collagen production in the dermis: plasma injections, microneedling, LED therapy, laser, radiofrequency.
These techniques, which vary in cost, deliver mixed results. On some stretch marks — particularly newer ones — they can noticeably improve their appearance. However, white stretch marks, the more mature ones, are always harder to treat and never fully disappear.
