Apply two coats of Critical Care Base Coat to clean, dry nails, using smooth, even strokes for full coverage. Ensure you seal the free edge (tip) of the nail to help protect against breakage. Wear alone as an intensive strengthening treatment, or follow with your chosen Custom Colour shade for a polished finish. For best results, pair with your favourite Jessica Top Coat to enhance shine and extend wear.
Healthy nails start with well-cared-for cuticles. Apply Nourish each day to keep cuticles soft and hydrated, and massage Phenomen Oil each evening to deeply condition and support nail growth.
Jessica’s prescriptive base coats are formulated to feed and strengthen the nail gradually. If you’re not wearing colour, reapply your base coat every 2–3 days to maintain consistent nourishment and protection.
I don’t know how it works or why but it does.
I have had soft, splitting nails for years, 6 weeks of twice weekly application and my nails are growing well, no splits, no peeling. So happy with this product! 10/10
