According to the [[American Academy of Dermatology]], the most common types of moles are [[skin tags]], raised moles, and flat moles. [[Benignity|Benign]] moles are usually brown, tan, pink, or black (the latter especially on dark-colored skin). They are circular or oval and are usually small (commonly between 1–3 mm), though some can be larger than the size of a typical pencil eraser (>5 mm). Some moles produce dark, coarse hair. Common mole hair removal procedures include plucking, cosmetic waxing, [[electrology|electrolysis]], [[Threading (epilation)|threading]], and cauterization.

===Aging===
Moles tend to appear during early childhood and during the first 30 years of life. They may change slowly, becoming raised, changing color, or gradually fading.<ref>{{cite web|url=http://www.webmd.com/skin-problems-and-treatments/guide/moles-freckles-skin-tags|title=Moles, Freckles, Skin Tags: Types, Causes, Treatments|work=WebMD}}</ref> Most people have between 30 and 40 moles, but some have as many as 600.<ref>{{cite news|url=https://www.bbc.co.uk/news/health-11813378|title=Skin moles link to delayed ageing|work=BBC News|date=22 November 2010}}</ref>

The number of moles a person has was found to have a correlation with [[telomere]] length.<ref>{{cite journal  |vauthors=Bataille V, Kato BS, Falchi M, etal |title=Nevus size and number are associated with telomere length and represent potential markers of a decreased senescence in vivo |journal=Cancer Epidemiology, Biomarkers & Prevention |volume=16 |issue=7 |pages=1499–1502 |date=July 2007  |pmid=17627017 |doi=10.1158/1055-9965.EPI-07-0152|doi-access=free }}</ref> However, the relation between telomeres and [[Senescence|aging]] remains uncertain.<ref>{{cite journal  |vauthors=Gomes NM, Ryder OA, Houck ML, etal |title=Comparative biology of mammalian telomeres: hypotheses on ancestral states and the roles of telomeres in longevity determination |journal=Aging Cell |volume=10 |issue=5 |pages=761–768 |date=October 2011  |pmid=21518243 |pmc=3387546 |doi=10.1111/j.1474-9726.2011.00718.x}}</ref>

===Complications===
The [[American Academy of Dermatology]] says that the vast majority of moles are benign.<ref name="aad.org" /> Data on the chances of transformation from melanocytic nevus to [[melanoma]] is controversial, but it appears that about 10% of malignant melanomas have a precursor lesion, of which about 10% are melanocytic nevi. Therefore, it appears that malignant melanoma quite seldom (1% of cases) has a melanocytic nevus as a precursor.<ref>{{cite journal |author=Fernandes NC |title=The risk of cutaneous melanoma in melanocytic nevi |journal=Anais Brasileiros de Dermatologia |volume=88 |issue=2 |pages=314–315 |year=2013 |pmid=23739702 |pmc=3750908 |doi=10.1590/S0365-05962013000200030}}</ref>
