CND Strengthener RXx Nail Strengthener 0.5 fl oz — Thickening, Fast-Drying Protective Coat for Thin Nails

CND Strengthener RXx is a nourishing nail treatment that builds noticeable thickness and protects thin, fragile nails while smoothing the nail surface.

Designed as a protective, fast-absorbing coating, CND Strengthener RXx combines conditioning vitamins and essential fatty acids with a breathable formula that resists chipping, peeling and splitting. It’s applied like a polish to provide immediate reinforcement and a smoother appearance, while ingredients such as Omega-6, Omega-9 and vitamins A, B and E help condition and support the nail plate over time.

How does Strengthener RXx reinforce weak or thin nails?

Strengthener RXx deposits a durable yet flexible layer that immediately increases nail thickness and reduces visible ridges. The formula is engineered to bond to the nail surface, helping to protect against everyday stresses that cause splits and breakage.

• Thickening coating for instant reinforcement
• Flexible finish that moves with the nail to prevent cracking
• Helps smooth ridges for a more even surface
• Resists common wear like chipping and peeling

What conditioning ingredients are included and why do they matter?

CND incorporates essential fatty acids (Omega-6 and Omega-9) plus vitamins A, B and E to help nourish the nail plate. These ingredients support hydration and pliability, which contributes to reduced splitting and a healthier-looking nail over regular use.

• Omega-6 and Omega-9 to help preserve nail flexibility
• Vitamin A and B to support surface conditioning
• Vitamin E for antioxidant support and smoothness
• Fast-absorbing delivery for minimal waiting time

Is this product safe and suitable for regular application?

Yes — the formula is breathable, allowing water and oxygen to pass, and it’s free from many common harsh additives. It dries quickly and is formulated without toluene, DBP, camphor, xylene and several other controversial ingredients, making it appropriate for routine use as a strengthening treatment.

How should I use CND Strengthener RXx for best results?

• Reapply as directed for maintenance and added strength
• Can be used alone or under color polish as a base
