Stretch marks, or striae, are streaks or lines that appear on the skin due to rapid stretching or tearing of the dermis, the middle layer of the skin. They commonly occur when the skin expands quickly, which disrupts the collagen and elastin fibers responsible for maintaining skin elasticity. These marks can appear red, purple, or dark brown in their initial stages and often fade to a lighter color over time. Stretch marks typically form during periods of rapid weight gain, such as during pregnancy, puberty, or significant changes in body size. Other factors include hormonal changes, certain medical conditions, and the use of corticosteroid medications. The skin's ability to accommodate such changes varies from person to person, influencing whether stretch marks develop.
Treatment options for stretch marks include topical treatments, such as creams containing retinoids or hyaluronic acid, which may improve their appearance by promoting collagen production. Laser therapy and microdermabrasion are more intensive methods that can help reduce the visibility of stretch marks by targeting the skin's deeper layers. Additionally, maintaining a healthy weight and keeping the skin well-moisturized can help minimize their appearance. While these treatments can improve the look of stretch marks, they may not completely eliminate them. In many cases, stretch marks eventually become less noticeable over time without intervention.
