No color changing?TEST: let the nails touch the ice or put them under the cold flowing tap water,likewise, soak them in quite hot water. Above actions can clearly see the color chaning for your nails.2. Not dry?Excluding the factor of the dryer lamp, It is actually dry, please don't foget to use the nail cleanser or the rubbing alcohol to wipe the sticker layer after curing the top coat. 3. Too thick?To apply thin coats, make sure the brush don't have to much on it before starting the strokes.4.Peel off easily? (1)It is vital that you do not get the polish on your skin, make sure you wipe it off very well.( **If cure it while on your skin, your gel nails will likely chip quick/peel off within a day or two**)(2)Without using a nail file to dehydrate your nail make the nail surface dry and rough. (4)Not enough rubbing alcohol to wipe the sticky layer, or it will be cracked.(3)Curing too long time under the lamp that influence the nail's durability.(5)Painting too much for the base&top coat will make the gel shrink.(6)Different brand base coat used with our brand gel that MAY influence its compatibility.
