Painting the nails with colored [[nail polish]] (also called nail lacquer and nail varnish) to improve the appearance is a common practice dating back to at least 3000 BC.

Acrylic nails are made out of acrylic glass ([[Poly(methyl methacrylate)|PMMA]]). When it is mixed with a liquid monomer (usually ethyl methacrylate mixed with some inhibitor) it forms a malleable bead. This mixture begins to cure immediately, continuing until completely solid in minutes. Acrylic nails can last up to 21 days but can last longer with touch-ups. To give acrylic nails color, gel polish, nail polish, and dip powders can be applied.<ref>{{cite web |url=https://www.nailsmag.com/386817/secret-ingredient-acrylic-liquid |title=Secret Ingredient: Acrylic Liquid |work=Nails |date=June 27, 2011 }}</ref>

[[Gel nails]] can be used in order to create artificial nail extensions, but can also be used like nail polish. They are hardened using ultraviolet light. They last longer than regular nail polish and do not chip. They have a high-gloss finish and last for two to three weeks.<ref>{{cite web |url=https://www.huffingtonpost.co.uk/entry/are-gel-nails-damaging_uk_5d52b0bae4b05fa9df04c708 |title=Gel Manicures Look Good, but What's the Damage to Your Nails? |work=[[HuffPost]] |date=12 October 2019 }}</ref>
