A French manicure is a natural-toned finish (milky, pink or sandy) with a white line along the free edge of the nail, known as the smile line. With gel polish it is done just like a regular application, except that instead of a colour you use a cover base, and the white line is painted with a brush, made with a stencil or shaped with top forms. Below you will find the proportions of the classic, the techniques, the baby boomer version and ideas for the season.
Classic French manicure: proportions and shape
Three things determine a beautiful result:
- The smile line follows the natural boundary of the free edge or sits slightly above it. Both ends of the line on the sides of the nail should be at the same height.
- The thickness of the line depends on the nail length: the shorter the nail, the thinner the line. A white band that is too wide visually shortens the nail.
- The base shade is semi-sheer, milky or pink, evening out the colour of the nail. Cover bases are ideal for this, for example "Strong Milky White Base".
The classic looks best on squoval, oval or almond-shaped nails. How to choose a shape is explained in our article nail shapes and their names.
French manicure with gel polish step by step
- Preparation. Shape the nails, push back the cuticles, remove the surface shine and degrease.
- Base. Apply a thin layer of cover base and cure. If the nail colour is uneven, apply a second layer, just enough for the nail to look smooth but still natural.
- White line. Draw the smile line using one of the methods described below and cure. If the white does not cover well enough, a second thin layer is better than one thick one.
- Top coat. Cover the whole nail with top coat, seal the free edge and cure.
- Finishing. If the top coat has a tacky layer, wipe it off with a cleanser and apply cuticle oil.
If you want a subtler effect, choose a milkier base: the lower the contrast between the base and the white, the more natural the result looks.
Line with a brush, stencil or top forms
With a brush
You will need a thin long liner brush or a flat angled brush and a thick, well-covering white gel that does not spread, for example "Liner-Spider Gel White". You will find brushes of various shapes in the brushes section.
- On the cured base, mark three points: both ends of the line at the sides and the middle.
- Join them with an arc, turning your finger rather than the brush, which gives a more even line.
- Fill in the area up to the edge of the nail and seal the edge.
- Until you get the hang of it, cure each nail separately so the line does not have time to spread.
With a stencil
French manicure stickers are applied to a cured, non-tacky base. Apply the white layer thinly, remove the sticker before curing, and then cure. On a tacky surface the stickers would pull the coating off. Before applying a sticker, press it against the nail along its full length, especially at the sides, otherwise the white will seep under the edge and the line will be uneven.
With top forms or a stamp
A top form with white gel is pressed against the nail and creates an identical smile line on every nail. The technique is described in the article nail extensions with top forms. A quick method at home is a silicone stamp: the tip of the nail is pressed into the white gel on the stamp, and the excess at the sides is wiped away.
The baby boomer (ombre French) technique
Baby boomer is a variation of the French manicure in which the white at the edge of the nail blends smoothly into a natural shade near the cuticles. A thick rubber cover base works well for this, for example "RB Cover Base Baby Boomer".
- Cover the nail with cover base and cure.
- Apply a second layer of base, and a white strip near the free edge.
- Before curing, blend the colours: dab with a sponge or sweep an ombre brush from the edge of the nail towards the cuticles until the boundary disappears.
- Cure and, if necessary, reinforce the white edge with a second thin layer.
- Apply the top coat.
The area near the cuticles should stay natural: the white must not reach the base of the nail. Use a clean sponge for each nail, or cut off the used edge, otherwise lumps of already thickened gel will end up in the transition.
Coloured and micro French
- Micro French is a very thin line right at the edge of the nail. It looks minimalist and suits short nails.
- Coloured uses any colour instead of white: a pastel, rich red, black or a metallic shade.
- Double line is two thin lines in different colours one above the other.
- V-shaped line is an angle instead of an arc; it looks especially beautiful on almond-shaped nails.
- Sparkly line is an edge with glitter or chrome powder.
French manicure for short nails
A French manicure suits short nails if you follow a few rules. The line must be very thin and follow the natural smile line: if placed high, it shortens the nail even more. Choose a pink base shade, which visually lengthens the nail bed, and keep the shape natural, an oval or a squoval. A micro line is an excellent choice for short nails. If the free edge is very short or uneven, the smile line can also be drawn slightly below the edge, which hides the irregularities, but the line must be even on all nails.
Common mistakes: a crooked line, a smile that is too thick
- Asymmetrical line ends. Mark the points before drawing and look at the nail from the front.
- A white band that is too thick. The nail looks shorter and the finish looks bulky.
- A white layer that is too thick. White pigments absorb UV light, so a thick layer may not cure all the way through. Two thin layers are better.
- An unsealed edge. The coating starts to lift from the free edge.
- White that is too runny. The line spreads before curing, so choose a thick gel or gel paint.
