In children who are not yet teens (adolescents), most stretch marks occur in those who are overweight. In the United States, 70% of adolescent girls and 40% of adolescent boys have stretch marks. These are due to growth and stretching of the skin.
Stretch marks are a normal part of puberty for most people. People who are obese often have stretch marks.
Hormonal changes
Skin changes during puberty are the most common reason for stretch marks on the breasts. “They develop when your skin rapidly stretches as your breasts develop,” Dr. Akhtar says.
Stretch marks are very common. They're harmless and often get less visible over time.
They're common in pregnant women, especially during the last trimester. Stretch marks aren't painful or harmful, but some people don't like the way they make their skin look. Stretch marks don't require treatment.
Medically, stretch marks don't require treatment because they aren't harmful or painful. They usually fade over time, with or without treatment, but may never go away completely.
Generally, breasts continue to grow until the age of 17-18. However, they may keep developing until your early or mid-20s. The growth rate and the time when they stop developing differ from person to person, largely due to genetic and hormonal factors.
Even young teenagers have breasts that can start to succumb to this natural law of the universe. In a society that prioritizes the perkiness of breasts, many women feel the pressure to have an “ideal” breast shape, which often involves having C- or D-cup-sized breasts that stay upright without the support of a bra.
The marks occur when a person experiences a significant amount of growth or weight gain in a short period of time, such as during puberty. Getting stretch marks does not necessarily mean a person is overweight. Thin people can get the marks too, especially when experiencing a rapid growth spurt.
In general, stretch marks from weight loss fade or disappear completely on their own. Sometimes rapid weight loss can actually cause stretch marks because of excess skin weighing down on the healthy skin.
The skin is stretched as a consequence of underlying tissue expansion. There is an inflammatory reaction in the skin that is responsible for the characteristic red or purple colour. The inflammation eventually fades and is replaced by scar tissue.
Through puberty, the skin of children progressively darkens with no differences between sexes prior to adolescence.
Stretch marks form at a 90 degree angle to the direction in which the skin stretches. On the thighs, stretch marks often first appear as raised pink or purple linear streaks on the skin. Over the next few months or years, these marks change to white or silver scars.
In children who are not yet teens (adolescents), most stretch marks occur in those who are overweight. In the United States, 70% of adolescent girls and 40% of adolescent boys have stretch marks. These are due to growth and stretching of the skin.
There is a gentle slope from the breast bone to the nipple, with the nipple pointing outward and parallel to the ground. The ideal breast does not sag and appears firm and rounded. From a frontal view, both nipples fall evenly on a horizontal line that runs midway between the shoulder and elbow.
Teens that are already at a normal weight but want to lose weight in their breasts risk vitamin and mineral deficiency. Exercise will not make breasts larger or smaller or perkier as there are not any muscles in the breast.
In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18, however in some cases they can continue to grow into her early twenties.
Several factors can contribute to smaller breast size, including genetics, hormonal imbalances, and medical conditions such as amazia, where there is little to no breast tissue present. Additionally, factors like height, weight, and post-puberty underdevelopment can also influence breast size.
Stretch marks don't hurt, but they can affect your mental health. They can make you worry about how others look at you. They can also affect how you think about yourself and your behavior. You may experience stress, anxiety and depression.
Rapid growth is a significant cause of stretch marks on the buttocks, and treatment is often sought. During puberty, both boys and girls experience quick growth spurts, often leading to stretch marks. The skin stretches rapidly to accommodate this growth. This can lead to new stretch marks forming.
