kreukels

Kreukels is the Dutch term for creases or wrinkles. The concept describes folds or lines that form in surfaces under stress, whether in textiles or in living tissue such as skin.

In textiles, kreukels are creases that appear after washing, drying, storage, or handling. Different fabrics crease to varying degrees depending on fiber content, weave or knit, and fabric finish. Cotton and linen tend to wrinkle more easily than synthetic fibers like polyester or blends with crease-resistant finishes. Removal typically involves ironing or steaming, while prevention can be achieved through careful washing, avoiding overloading the machine, using appropriate heat settings, and employing crease-resistant finishes or careful storage.

In skin, kreukels refer to wrinkles that develop with aging and exposure to environmental factors. Aging causes changes in the dermis, including a reduction in collagen and elastin, leading to diminished skin elasticity. Ultraviolet (UV) radiation from sun exposure accelerates this process, as do smoking and repeated facial expressions. Common sites include the face, neck, and hands. Dynamic wrinkles form from muscle movement, while static wrinkles are visible at rest. While wrinkles are a normal part of aging, they are not generally considered a disease.

Prevention and management differ by context. For textiles, proper laundering, avoiding over-drying, and using appropriate ironing practices help maintain smooth fabrics. For skin, sun protection, regular moisturization, and the use of retinoids or antioxidants can slow visible aging, while clinical options such as botulinum toxin, dermal fillers, laser resurfacing, or chemical peels may be discussed with a qualified professional for more pronounced wrinkles.
