SUPPORTIVE FOR NAIL FUNGUS: Thanks to the high-quality care complex with tea tree oil, Bee Venom & aloe vera, our Nail Care Pen works very well and is your additional cosmetic care for nail fungus treatments STRENGTHENED NAILS: Our Nail Care Pen noticeably supports the nail even with cracked & brittle nails. The serum ensures optimal moisture supply & long-term regeneration. UNIQUE EFFECT: The nail matrix technology in the Nail Care Pen ensures that the nail is opened at the cellular level in the first step. This allows the nourishing active ingredients to reach the nail fungus at the nail root where it arises & to fully develop their effect. EASY TO USE: File the nail with a file and remove porous, brittle areas - moisten the brush by turning it on the top. Then apply the product to the affected area and surrounding area. Leave it to work until it is completely dry.
