Product Type Base Coats

Jessica Critical Care is an intensive base coat created for very weak, brittle, or easily damaged nails that need extra care and support. Designed as part of Jessica’s prescriptive nail care system, this treatment-style base coat helps nails look stronger, smoother, and better maintained while creating a reliable foundation for colour or a natural, cared-for finish on its own.

The formula features Keratin, Soy, and Wheat Proteins to support the appearance of fragile nails and help improve the look of the nail surface over time. It is especially useful if your nails feel thin, break easily, or struggle to maintain length. Worn regularly, it helps create a more flexible, polished-looking base so your nails appear neater, healthier, and more resilient as part of your routine.

Suitable for: Very weak, brittle, thin, or easily damaged nails that need a supportive base coat and regular conditioning care.

Benefits:

  • Supports stronger-looking nails: Helps improve the appearance of nails that feel fragile or prone to breaking.
  • Protein-rich formula: Keratin, Soy, and Wheat Proteins help support a smoother, better conditioned nail surface.
  • Can be worn alone or under colour: Use as a treatment-style base or as the first step before Jessica Custom Colour.
  • Helps nails look more resilient: A useful option when nails need consistent care between manicures.
  • Smooth application: Glides on evenly to create a neat, polished-looking finish.

Key ingredients:

  • Keratin: Helps support the look of stronger, smoother nails.
  • Soy Protein: Included to help condition and support fragile-looking nails.
  • Wheat Protein: Helps improve the appearance of the nail surface with regular use.

How to use:

  • Apply to clean, dry nails using a generous amount of product on the brush.
  • Use long, smooth strokes to cover each nail fully.
  • Finish by brushing across the free edge of the nail to help seal it.
  • Follow with your chosen Jessica Custom Colour or apply a second coat if wearing alone.

Expert tips:

  • If you are not wearing colour, reapply every 2 to 3 days to keep nails feeling cared for.
  • Apply Jessica Nourish daily and Jessica Phenomen Oil at night to keep cuticles looking soft and neat.
  • Seal the free edge with each layer to help your manicure look smoother for longer.

Good to know:

  • This base coat is best suited to nails that need extra support rather than nails that are already strong and balanced.
  • Works well as part of a full Jessica manicure routine with base coat, colour, top coat, and cuticle care.
