1. Key Ingredients of Nail 15: The lotion contains a rich formula of moisturizing and strengthening ingredients for nails, most notably: * **Urea:** Helps to deeply moisturize the nail and surrounding skin, and softens thick or hardened nails to facilitate the absorption of other nutrients. * **Salicylic Acid:** Acts as a gentle exfoliant to remove dead skin cells around the nails, helping to cleanse and prepare the nail environment for healthy growth. * **Panthenol (Pro-Vitamin B5):** Provides intense hydration and strengthens the nail structure to prevent breakage, also contributing to its flexibility. * **Castor Oil:** Nourishes nails and provides them with the necessary fatty acids to prevent dryness and cracking. * **Vitamin E:** A powerful antioxidant that protects nails from harmful environmental factors and promotes healthy growth. 2. Benefits and Uses of Nail 15: * **Strengthening Weak Nails:** Treats the problem of brittle and weak nails that break or crack easily. * **Stimulating Nail Growth:** Nourishes the nail matrix (the part responsible for growth), helping nails grow faster and stronger. * **Moisturizing the Skin Around the Nail:** Eliminates dryness and excess cuticle (hangnails) around the nails that sometimes cause pain. * **Improving Nail Appearance and Texture:** Restores the natural shine of nails and makes their texture smooth and even. * **Protecting Nails:** Forms a protective layer for nails constantly exposed to water, detergents, or frequent use of cosmetics (like acetone and nail polish removers). 3. Correct Usage Method: 1. Wash your hands (or feet) and dry them thoroughly before use. 2. Apply a small drop of the lotion to each nail and the surrounding skin. 3. Gently massage the nail and skin in circular motions until the skin and nail bed have completely absorbed the product. 4. It is preferable to use it twice daily (morning and evening), and for best results, it is recommended to continue using it for several weeks.
