Stretch marks are essentially lesions that are located in the second layer of the skin called the dermis. They are caused by a decrease in the production of collagen fibres, which reduces the skin's thickness by 50%, as well as a decrease in the quality of elastin fibres.
If we asked anyone at random why they have stretch marks, they would likely provide a response that includes some form of numbers—for example, I gained 15 kilos in a few months during my last pregnancy or, when I was a teenager, I grew several centimetres in a really short time.
Indeed, most people tend to think that stretch marks are caused by the stretching of the skin. However, this isn’t exactly what happens. Although the stretching of the skin, especially if it happens quickly, is an aggravating factor, the real cause is hormones disequilibrium.
Cortisol and stretch marks
The body normally produces Cortisol, an essential stress hormone to our survival since it helps the body and brain overcome situations that are threatening or simply stressful.
When excessive amounts of Cortisol are produced, the skin becomes much more vulnerable. This happens, for example, during pregnancy, puberty, restrictive dieting or periods of intense psychological stress. Skin becomes less resistant and stretches form as a result. If the skin happens to also stretch significantly during this time, the resulting stretch marks will also be more intense.
How to prevent the appearance of stretch marks
The obvious answer would be: avoid situations that cause the body to produce large amounts of cortisol. Sounds easy but the reality is that we have very little control on it.
The best option is to turn over proper skincare using treatments specifically intended to help prevent stretch marks. Lierac Paris Laboratories have more than 45 years of expertise in the creation of targeted treatments to correct and prevent the appearance of stretch marks. The innovation: PHYTOLASTIL Soluté and Prevention Gel with a natural formula with Alchemilla, Ivy and Horsetail and a strong restructuring complex, capable of stimulating collagen and elastin synthesis.
The PHYTOLASTIL ritual
The best way to ensure the optimal performance of
PHYTOLASTIL treatments is to exfoliate the skin before their application. One great exfoliation option is BODY-HYDRA+ Micropeeling Scrub.
During pregnancy, start your stretch mark prevention routine as soon as you notice your body changing—usually around the 3rd month. If you’re already in the habit of using hydrating products every day, simply add a step to your routine by applying the gel before your hydrating cream, the same way you would apply a serum to your face.
For a corrective action: Apply
PHYTOLASTIL Soluté instead on already set and visible stretch marks.
Applied twice a day to areas where stretch marks are visible. It usually takes about two to three months for stretch marks to change in appearance. Although they won’t completely disappear, they will fade and look significantly better.
