SULLMAR 4‑in‑1 Nail Care Kit — Nail Hardener, Calcium Primer & Cuticle Oil for Thin, Brittle Nails

SULLMAR 4in1 Nail Care Kit combines a nail hardener, calcium primer, strengthening treatment and nourishing cuticle oil to repair, firm and hydrate thin or brittle nails.

This compact kit gathers four coordinated products designed to address common nail concerns—peeling, splitting, weak growth and dry cuticles—so you can manage nail health at home or on the go. Each formula targets a specific step in a simple routine: soften and remove excess cuticle, strengthen the nail plate, reinforce with calcium, and lock in moisture with vitamin-rich oil. The set works best when used consistently and as part of a gentle manicure regimen.

How does this kit rebuild weak or peeling nails?

The calcium primer and strengthener are formulated to firm the nail surface and reduce delamination that causes layers to peel. Regular application helps create a more resilient nail plate that resists everyday stresses like typing and light impact.

• Calcium-rich primer to add structural support to the nail plate
• Strengthener smooths surface ridges and improves gloss
• Thin, even coats recommended to avoid flaking of the treatment

What role does the cuticle remover gel cream and oil play?

The cuticle remover gel softens dead skin around the nail edge so it can be gently pushed back or trimmed, while the cuticle oil replenishes moisture and vitamins to the nail fold. Together they reduce hangnails, improve the look of the nail line and create a healthier base for growth.

• Remover gel loosens excess cuticle for safe removal with tools
• Cuticle oil pen delivers concentrated hydration and nourishment
• Daily oil application helps prevent dryness and brittle edges

Can I use these products with polish and other manicures?

Yes—each product is designed to integrate into regular manicure routines. Apply the primer and strengthener before colored polish or use them on natural nails between polishes to maintain strength and shine.

• Apply thin primer layer before base coat for fortified foundation
• Strengthener can be used as a base or top coat, if applied thinly
• Use cuticle oil after polish removal and as an overnight treatment

How soon will I notice improvements in nail appearance?

Visible improvements—like smoother surface and reduced flaking—can appear within a few applications, but full nail regeneration depends on individual growth rates. Consistent use over several weeks will produce the most measurable results.

• Surface shine and reduced roughness often visible within days
• Stronger, less split nails typically seen after multiple weeks
• Combine with gentle filing and protective habits for best outcomes

Who is this for: The SULLMAR 4in1 Nail Care Kit suits anyone with thin, brittle, or peeling nails who wants an at-home regimen combining renovation and daily maintenance. It’s appropriate for those who wear polish regularly and for people seeking to improve nail condition with targeted products—cuticle remover for prep, calcium primer for reinforcement, a strengthener for shine and durability, and a nourishing oil to keep the nail fold healthy.
