Our nail care solution set contains glycerin and matrine root extract. It can strengthen nail care kits to provide comprehensive care for healthy nails. Glycerin effectively locks in moisture and deeply moisturizes nails and surrounding skin. Its application is simple: clean and dry the nail and surrounding skin, gently shape the nail with a sponge nail file, and polish the surface of the nail. Use a wooden fork to gently trim the cuticles around the edges of your nails. Apply the appropriate amount of nail polish to your nails. Massage gently with your fingertips to absorb. It can also help repair damaged nails and increase toughness.
