White roll is the white line that borders the top of the upper lip.{{cite journal |last1=Mulliken |first1=John B. |last2=Pensler |first2=Jay M. |last3=Kozakewich |first3=Harry P.W. |title=The Anatomy of Cupidʼs Bow in Normal and Cleft Lip |journal=Plastic and Reconstructive Surgery |date=September 1993 |volume=92 |issue=3 |pages=395–403 |doi=10.1097/00006534-199309000-00001 |pmid=8341737 |s2cid=44800426 }}{{cite journal |last1=Kirschner |first1=Richard E. |last2=LaRossa |first2=Don |title=Cleft Lip and Palate |journal=Otolaryngologic Clinics of North America |date=December 2000 |volume=33 |issue=6 |pages=1191–1215 |doi=10.1016/s0030-6665(05)70277-2 |pmid=11449783 }} It is an adnexal mass of specialized glands and fat. White roll occurs naturally for nearly everyone, although it can be not white and less visible for dark skinned individuals. Well defined white roll indicates youthfulness and is considered aesthetically pleasing.{{cite journal |last1=Sanniec |first1=Kyle |last2=Carboy |first2=Jourdan |last3=Thornton |first3=James |title=Simplifying Lip Reconstruction: An Algorithmic Approach |journal=Seminars in Plastic Surgery |date=May 2018 |volume=32 |issue=2 |pages=069–074 |doi=10.1055/s-0038-1645882 |pmid=29765270 |pmc=5951711 }}

With age, white roll often becomes less defined.{{cite news |last1=Rosenstein |first1=Jenna |title=Do You Have an Anti-Aging Routine for Your Lips? |url=https://www.yahoo.com/lifestyle/why-anti-aging-lips-174716001.html |work=Yahoo! |agency=Harper's Bazaar |date=24 February 2020 }} This is due to sun damage, changes in facial fat, and decreasing collagen in the area right above the lip.{{cite news |last1=Strugatz |first1=Rachel |title=Kylie Jenner Spurs Lip Plumper Craze in Beauty Market |url=https://wwd.com/beauty-industry-news/beauty-features/kylie-jenner-spurs-lip-plumper-craze-beauty-market-10710565/ |work=WWD |date=22 November 2016 }} White roll can also be accentuated using injectable fillers.{{cite journal |last1=Blandford |first1=Alexander D. |last2=Hwang |first2=Catherine J. |last3=Young |first3=Jason |last4=Barnes |first4=Alexander C. |last5=Plesec |first5=Thomas P. |last6=Perry |first6=Julian D. |title=Microanatomical Location of Hyaluronic Acid Gel Following Injection of the Upper Lip Vermillion Border: Comparison of Needle and Microcannula Injection Technique |journal=Ophthalmic Plastic & Reconstructive Surgery |date=May 2018 |volume=34 |issue=3 |pages=296–299 |doi=10.1097/IOP.0000000000000960 |pmid=28723735 |pmc=5773414 }}{{cite journal |last1=Jacono |first1=Andrew A. |title=A New Classification of Lip Zones to Customize Injectable Lip Augmentation |journal=Archives of Facial Plastic Surgery |date=1 January 2008 |volume=10 |issue=1 |pages=25–29 |doi=10.1001/archfaci.10.1.25 |pmid=18209119 }}{{cite news |last1=Sundaram |first1=Hema |title=A 25-Year-Old Woman Seeking Subtle Lip Enhancement |url=https://www.medscape.org/viewarticle/588145 |work=Medscape }}

Sometimes white roll is absent or damaged, due to trauma or cleft lip, in which case it could be reconstructed with plastic surgery.{{cite journal |last1=Chandran |first1=Geethan |last2=Lalonde |first2=Donald H |title=Obtaining a good lip roll in congenital, secondary and traumatic cleft lip repairs |journal=Canadian Journal of Plastic Surgery |date=December 2013 |volume=21 |issue=4 |pages=248 |doi=10.1177/229255031302100409 |pmid=24497768 |pmc=3910528 }}{{cite journal |last1=Murthy |first1=Jyotsna |title=The refinement of the median tubercle of cleft lip |journal=Indian Journal of Plastic Surgery |date=May 2018 |volume=51 |issue=2 |pages=131–136 |doi=10.4103/ijps.IJPS_214_17 |pmid=30505082 |pmc=6219361 |doi-access=free }} However, it is difficult to achieve satisfactory results using surgery, because malalignment of even a millimeter is noticeable and unattractive. It is therefore sometimes tattooed instead.{{cite journal |last1=Stal |first1=Samuel |last2=Hollier |first2=Larry |title=Correction of Secondary Cleft Lip Deformities |journal=Plastic and Reconstructive Surgery |date=April 2002 |volume=109 |issue=5 |pages=1672–1681 |doi=10.1097/00006534-200204150-00031 |pmid=11932617 }}
