What technique is commonly used to achieve a French manicure?

The technique commonly used to achieve a French manicure is characterized by the application of white polish to the tips of the nails, combined with a nude or pink base coat on the rest of the nail. This classic style is distinguished by its clean and natural appearance, with the white tips providing a sharp contrast against the base color. The color combination epitomizes elegance and simplicity, making it a popular choice for many.

In the context of other techniques, applying rhinestones to the tips adds embellishment rather than adhering to the minimalist aesthetic of a French manicure. Using a gradient effect with multiple colors introduces complexity that departs from the traditional look of the French style. Moreover, using only clear polish on all nails does not achieve any color contrast or the signature white-tipped design that defines a true French manicure. Therefore, the focus on white tips and a nude or pink base effectively embodies the essence of this manicure style.
