Stretch marks are scars on the skin that have been subjected to stretching in a short period of time, causing the fibres to break. Although they could actually appear anywhere on the body, the increase in weight or volume in the body does not usually occur uniformly and there will be areas of the body that are more sensitive to the appearance of stretch marks.
The chest is one of the parts of the body most vulnerable to the appearance of stretch marks. This is because its an area that is exposed to changes in volume, as it adapts to growth and its function. This is especially relevant in the case of women.
Before puberty, there are not many differences in the breast area between boys and girls. Once puberty begins, girls begin to develop breasts as part of natural growth development. Breasts are a secondary sexual character in girls, and as they transition from childhood to adult life they will grow and develop to a great extent.
Puberty has a variable duration, but usually covers about 2-3 years in which somatic growth will be accelerated, and all body tissues will increase in volume. This change is very evident in the chest. And although the growth of this area in girls is not homogeneous, due to genetic and hormonal influence, the changes will be very visible.
It is a time when stretch marks appear very frequently. In addition to the great growth, it is a time of life in which self-care routines are neglected, so that it is usually difficult for them to comply with preventive activities, which in this case, prevent the appearance of stretch marks.
The development of the breast, however, is completed during pregnancy and lactation. It is another vulnerable time for the appearance of stretch marks. The chest is going to increase a lot in volume progressively. It is something very striking especially during the first months of pregnancy and during the first few days of breastfeeding. The good thing is that having this information, and having tools that prevent stretch marks, such as continuity in the application of Trofolastin.
In boys, although breast development is not the same as that of girls, there is also an increase in the volume of the chest area during puberty, primarily due to expense of muscle development than of the growth of the mammary glands themselves. So, although it is less common, boys can also have stretch marks on the chest. After puberty, practicing strength exercises (for example, with weights) that strengthen the muscles of the thoracic area can lead to the appearance of stretch marks. These too can benefit from preventative treatment.
