Wash your hands thoroughly with antibacterial soap and warm water. Dry them completely.
Trim the free edge of your nail to even off the new growth and keep your nails at the length you want them.
File the nail edge near your cuticle with an electric rotary file. A regular hand file will also work if you are careful not to file the natural nail. Angle the file to bevel the edge of the gel so that it will blend seamlessly with the new gel.
Hold the edge of the electric file flat against the surface of your nail, and file the entire surface of the gel. This is to keep the gel overlay from getting too thick when you fill it.
Angle the drill to make a new groove -- or smile line -- between the pink and white gels. Brush away the dust with a soft, dry nail brush.
Scoop a little white gel onto your brush and redo the white portion of each nail. Let the first hand sit under the UV lamp for two to three minutes before you do the second one. If you're doing the nails of someone other than yourself, you can begin working on the other hand while the first hand is under the UV lamp.
Apply pink gel to the cuticle area of the first hand, blending it well with the existing gel overlay. Apply this only up to the white gel, not over it. Pat it and smooth it, as opposed to using long brush strokes, to make sure the backfill line thickens properly. Set the first hand under the UV light for two to three minutes as you work on the second hand.
Brush a second coat of pink gel onto the nail. Cure both hands.
Use a cotton ball or pad dipped into rubbing alcohol to clean off the nails and get rid of any sticky residue.
Brush a clear gel topcoat over all 10 nails, from cuticle to free edge, and let both hands cure under the UV lights for two to three minutes.
Correct any flaws with a hand file. Wash your hands thoroughly.
Use glue-on white tips and pink gel if you are not skilled enough to create a pink-and-white French gel manicure.
Never peel off gel nails or tips -- doing so damages your nails.
