Mona Lisa ditched her eyebrows to keep up with Florentine fashion

The Mona Lisa's famously smooth brow line is not an oversight by Leonardo da Vinci but a deliberate reflection of Renaissance beauty standards. In late 15th- and early 16th-century Florence, a high, unbroken forehead was considered the height of elegance, and many women plucked or shaved their eyebrows to achieve it. ^[1][2]

The Fashion for a High Forehead

Florentine women of the period often removed their eyebrows entirely, sometimes using tweezers, razors, or depilatory creams. The goal was to create an expansive, smooth forehead, which was seen as a sign of nobility and refinement. This practice was not limited to the upper classes; it was widely followed among those who could afford to keep up with fashion. ^[1][3]

Leonardo da Vinci, ever attentive to the world around him, painted his sitter according to this trend. The Mona Lisa's lack of eyebrows is therefore not a mystery but a mark of her adherence to contemporary Florentine style. Art historians have long noted that her appearance matches descriptions of fashionable women of the time. ^[2][4]

Evidence and Interpretation

In 2004, a French engineer named Pascal Cotte used a high-resolution multispectral camera to scan the painting and claimed to have found traces of a left eyebrow. However, this finding remains debated, and many scholars argue that any faint marks are likely later additions or artifacts of aging rather than original details. Even if Leonardo initially sketched eyebrows, the final painting shows none, consistent with the fashion. ^[4][5]

• Renaissance beauty ideals prized a high forehead, often achieved by plucking the hairline as well as the eyebrows. ^[1]
• Depilatory practices were documented in contemporary cosmetics texts and letters. ^[3]
• Leonardo's other portraits, such as Ginevra de' Benci, also show subjects with minimal or no eyebrows. ^[2]

So the Mona Lisa's enigmatic gaze is accompanied by a fashion statement: she ditched her eyebrows to keep up with the Florentine elite. What might seem like an odd omission today was, in her time, a sign of beauty and status. ^[1][2]
