Our cuticle care pens are made with 100% Jojoba and Vitamin E oils. We do add premium fragrances for scent. Jojoba oil has many benefits, including its moisturizing ability, natural antifungal properties, and the fact that it's hypoallergenic. Both jojoba and Vitamin E oils are antioxidants, they promote nail growth, and have been used to help speed up wound healing and reduce scarring. These oils keep the problem areas moisturized while the nutrients soak into the skin and nails. These cuticle care pens make it easy to get into all the narrow areas of the cuticles, sidewalls, and especially under the nail where the nail meets the skin.
