kråketær

Kråketær, or crow's feet, are wrinkles that form at the outer corners of the eyes. They are a common form of periorbital aging and range from fine lines to deeper grooves.

Causes include aging, loss of collagen and elastin, and thinning skin around the eyes. Sun exposure accelerates wrinkling (photoaging). Other factors are smoking, repetitive facial expressions, and genetics.

Anatomy: the skin around the eyes is among the thinnest on the body. Wrinkles originate from contraction of the orbicularis oculi muscle near the lateral canthus and often radiate outward.

Prevention and skincare: protect the eyes from sun with sunglasses and broad-spectrum sunscreen near the eyes, avoid smoking, and use gentle, retinoid-containing creams and antioxidants as advised by a clinician.

Treatments: non-surgical options include topical retinoids, fillers (hyaluronic acid), neuromodulators (botulinum toxin), chemical peels, laser therapy, microneedling, and radiofrequency. For extensive sagging, blepharoplasty can improve the appearance of the periorbital area.

In Norwegian usage, kråketær specifically describes these periorbital wrinkles; in English-language dermatology the term is crow's feet.
