To keep the cream effective, store the tube in a cool, dry place away from direct sunlight and keep the cap tightly closed after each use. Exposure to heat or moisture can alter the texture and reduce the stability of the ingredients over time. The product typically remains usable for up to twelve months after opening, but the exact duration is indicated by the batch code printed on the packaging; checking this code helps you determine when the product should be replaced. When adding the cream to a broader hand‑care routine, you can pair it with a mild cleanser and, if desired, a separate nail‑strengthening treatment, but avoid layering it with heavy oils or occlusive balms that might counteract its light absorption. The cream is not intended to diagnose, treat, or prevent any disease, and it should not be applied to broken skin.
