Apres Non-Acidic Gel Primer is the second step to creating beautiful Gel-X extensions. After applying the pH Bonder, Apres Non-Acidic Gel Primer creates a tacky surface on the nail that allows for better adhesion to the Gel-X tip. Formulated to be acid-free, this primer gently etches and preps the nail without any danger of causing any soreness or sensitivity that is commonly associated with acid based primers. Apres Non-Acidic Gel Primer will ensure a long lasting and comfortable wear for any set of Gel-X extensions!
