They are the three families in the Young Nails powder names. Core powders are the clear, natural, pink and white basics, such as 00 Core Clear, 02 Core Natural and 04 Core White. Cover powders are skin-tone shades such as 07 Cover Bare, 08 Cover Beige and 09 Cover Blush. Speed powders, such as 18 Speed Clear and 21 Speed White, are the third family. Each jar holds 45 g.
Young Nails lists its own Liquid Monomer in 6 and 32 oz sizes, labelled EMA, and a separate 32 oz Nail Liquid Monomer. Brands advise using their own liquid for the best result. Prep the nail with Young Nails Protein Bond, an acid-free primer with keratin, sold in 0.25 and 0.5 oz bottles. Each listing shows its own stock count.
Prep the nail, apply a thin coat of primer to the natural nail only and let it air-dry. Dip the brush in liquid, wipe off the excess, pick up a bead of powder and press it into shape on the nail, keeping product off the skin and the cuticle line. Acrylic sets in the air with no lamp. File and shape once it has set.
Young Nails trial kits for acrylic and for Synergy Gel are listed, along with Pro Acrylic Kits named Speed, Ultimate and Core, and a 22-colour set of 45 g jars. Kits are a quick way to try the system; check each listing for its contents and its stock, since some kits have only one or two left.
Keep jars closed between clients so the powder stays clean and dry, and store them sealed, away from heat and direct sunlight. Use a clean, dry brush, and do not return used powder to the jar. Label open jars with the shade number so reorders stay simple. Check each listing for stock before you plan an order.
